The toggle was absolutely positioned over the drawer's flex row, owned by
neither column. That forced two coupled workarounds: a stacking level so it
could beat whatever it landed on, and pl-12 on the sidebar header to reserve
space for a button that was not its child.
The sidebar column now always renders, at 224px expanded and a 40px rail
collapsed, and the toggle is a normal in-flow child of the column it controls.
No absolute, no z-index, no reserved padding, and nothing that can paint over
the button. It also stops the toggle from clipping the provider logo, which it
did in the collapsed state even before the z-index scale landed.
Costs 40px of drawer width while collapsed.
The sidebar toggle sits absolutely positioned over the drawer's flex row. With
the sidebar expanded it lands on the sidebar header, but once collapsed it lands
on the drawer header, which is sticky at z-chrome (10). The named-z-scale
refactor moved the toggle from z-20 to z-raised (1), so from then on the header
painted over it and swallowed the click: collapse the trace list and there was
no way to bring it back.
Moves the toggle to z-floating (30) and folds the two mirrored buttons into one,
since they only ever differed by icon, label and handler.
Covered by a Playwright spec, which is the tier that can see the layering: the
button stays visible and enabled either way, so the pre-fix failure is a click
interception that jsdom cannot reproduce.
The attempt row now prices the real arm (the payload's response_cost plus its own
routing classifier when it routed) beside the shadow arm (completion plus the
classifier cost the routing decision writes back), and flags turns litellm's
response cache served. A per-leg funnel table counts the eligible requests that
produced no row (lost the sampling dice, unjudgeable shape, concurrency shed),
so results can weigh judged rows against the traffic they stand for. Job results
gain per-slice and overall arm spends plus the coverage counts, the budget gates
charge the shadow arm's classifier spend against max_budget, and the dashboard
shows the measured cost comparison beside the win rate
Resolves LIT-6358

Lite ran Muse Spark 1.2 and Kimi K3 at whatever effort each provider happens to
default to. Set the ones their own docs name: Muse Spark 1.2 at xhigh, and Kimi
K3 at max, which is Kimi's own default and what the model map now declares for
that model.
Stacked on the map change, since without it kimi-k3 resolves to unknown levels
and the tier editor's capability-blind fallback list does not offer max.
* feat(guardrails): honor Lakera v2 skip-message flags and add advisory (inject_system_message) mode
Squashed rebase of bugfix/lakera-v2-skip-system-tool-messages onto latest
litellm_internal_staging (900+ commits ahead; a commit-by-commit rebase hit
repeated conflicts against the same files across earlier review-round
commits, so the branch's cumulative diff was reapplied in one pass instead).
Adds skip_system_message_in_guardrail/skip_tool_message_in_guardrail support
to Lakera v2, a third on_flagged: "inject_system_message" advisory mode, and
the associated masking-safety-guard hardening (multimodal content, non-
maskable message fields, combined messages+input, and structured Responses-
API input in advisory delivery) found across this PR's review rounds.
* fix(guardrails): don't let one invalid guardrail config crash proxy boot
init_guardrails_v2 had no try/except around initialize_guardrail, so a
guardrail whose litellm_params fail validation at construction time (for
example Lakera's on_flagged=inject_system_message combined with
mode=during_call, or a malformed advisory_system_message template) raised
uncaught and crashed the entire proxy at startup, taking down every other,
correctly-configured guardrail in the list. Catch ValueError/TypeError per
guardrail, log a warning, and skip it, matching the same pattern already
used for the DB-driven guardrail-creation path in guardrail_endpoints.py.
* fix(guardrails): preserve message fields and mask PII before advising in Lakera v2
Mask-in-place degraded to a hard block for any message carrying a field
beyond role/content (tool_call_id, tool_calls, name, cache_control), for a
message excluded by skip_system_message_in_guardrail/skip_tool_message_in_guardrail,
or for a message with no inspectable text, since it rewrote data["messages"]
wholesale from a synthetic role/content-only list built for the Lakera API
call. That made masking effectively unusable for any real tool-calling
conversation and made the skip flags flip every PII-only violation to a hard
block instead of masking just the in-scope text.
Replace the wholesale rewrite with a scope-index merge, reusing the same
merge_guardrailed_scoped_messages helper the OpenAI/Anthropic guardrail
translation handlers already use for this: patch content in place on a copy
of each original message actually sent to Lakera, and leave every
skipped/no-text/out-of-scope message untouched at its original position.
This also fixes on_flagged="inject_system_message" (advisory mode) shipping
raw unmasked PII to the model: a PII-only violation is now masked the same
way regardless of on_flagged, and the advisory note is reserved for flags
masking can't resolve on its own.
Addresses maintainer-reported regressions on BerriAI/litellm#34940.
* fix(guardrails): satisfy new lint gates for the masking/advisory fix
Parameterize the write-back helper's dict param and suppress the two new
lint rules that landed on the base while this branch was in flight: TQ008
(patching an internal collaborator) for two pre-existing tests unrelated to
this change, and LIT001 for a param that genuinely needs to mutate the
caller's request dict in place.
* fix(guardrails): normalize role casing in Lakera v2 masking scope, log skipped guardrails louder
Greptile finding: the masking scope helper compared roles case-sensitively
while filter_messages_by_skip_flags (used to build what's actually sent to
Lakera) normalizes casing, so an uppercase-cased "System"/"TOOL" role
survived the scope filter but was excluded from the inspected list. The
resulting length mismatch raised inside the strict positional zip, turning
a maskable PII-only violation into an unhandled request failure. Lowercase
the role comparison to match.
Also, per veria-ai's finding that a skipped invalid guardrail now fails
open: log it at error level with an explicit note that the proxy is
starting without that guardrail, so it's not mistaken for routine info.
* fix(guardrails): mask maskable PII in mixed violations before advising in Lakera v2
on_flagged="inject_system_message" only masked when a violation was
PII-only; a mixed violation (PII plus a non-PII flag like prompt injection)
fell straight through to the advisory branch with the raw PII still in
place, in both async_pre_call_hook and async_moderation_hook. Mask whatever
Lakera returned location data for before appending or logging the advisory,
so a mixed violation never ships raw PII just because something else was
also flagged.
Also degrade to blocking, same as block mode already does, when nothing
can be safely masked at all (multimodal content, or messages combined with
a Responses API input field) instead of showing an advisory note next to
raw, unredacted content.
Widened call_v2_guard/_mask_pii_in_messages/the write-back helper's message
parameters from list to Sequence to match what's actually passed through
from _filter_skipped_messages, instead of duplicating list(...) casts at
every call site.
* fix(guardrails): don't hard-block advisory mode for non-PII flags on non-maskable input
Bugbot finding: gating the entire inject_system_message branch on
is_multimodal_input hard-blocked every flagged request on Responses
instructions, combined messages+input, or multimodal content, including
a prompt-injection-only violation with no PII at all. Masking safety only
matters when there's actual PII to mask; a violation with no PII needs no
masking, so the advisory should still be delivered normally.
Only degrade to blocking when the breakdown actually contains a PII
detection and masking isn't safely possible. Otherwise, mask whatever's
maskable (if any) and deliver the advisory as before.
* fix(guardrails): require payload and breakdown for Lakera v2 advisory mode
Advisory mode's mixed-violation masking safety net can only redact
detected PII when Lakera's response carries both the breakdown (to
detect a PII hit at all) and payload (the location data to mask by).
payload=False or breakdown=False alongside on_flagged='inject_system_message'
silently forwarded raw PII next to the advisory note. Reject that
combination at construction and hot-reload time instead.
* fix(guardrails): skip_system_message_in_guardrail must not force-block Lakera masking
_has_responses_instructions treated any non-empty data["instructions"]
as unsafe to mask regardless of skip_system_message_in_guardrail, even
though that flag excludes the instructions-derived synthetic system
message from what Lakera ever inspects. PII detected purely in the
maskable non-system content was force-blocked instead of masked.
Also fixes pre-existing LIT010 (missing Final) violations in
_has_responses_instructions, _breakdown_has_pii_violation, and
async_post_call_success_hook that the rebase's lowered budget ceiling
now flags.
* chore: retrigger CI (GitHub Actions runner-acquisition failure on prior push)
* fix(guardrails): address maintainer review findings on Lakera v2 advisory mode
- Gate advisory_system_message template validation on on_flagged=
'inject_system_message', since block/monitor mode never reads it.
- Allow on_flagged='inject_system_message' with mode='during_call' at
construction/hot-reload instead of rejecting it; async_moderation_hook
already degrades gracefully (masks if possible, else logs a warning).
- reinitialize_guardrail now restores the previous live instance when the
new config fails to initialize, instead of leaving the guardrail deleted
entirely with nothing enforcing it.
- PATCH /guardrails/{id} rolls back the DB write and returns 422 when the
in-memory sync rejects the new config, instead of persisting a config
that never actually took effect and returning 200.
- Qualifire now rejects on_flagged values it doesn't implement (only
Lakera should accept 'inject_system_message'; LitellmParams flattens
the field across every guardrail config mixin).
* fix(tests): satisfy lint gates and update collateral test for advisory-mode fixes
- Add match= to a too-broad pytest.raises(ValueError), and suppress the
new TQ008 mocker.patch findings (same pattern already used by sibling
scenarios in this test).
- test_init_guardrails_v2_skips_invalid_guardrail_instead_of_crashing_boot
used mode='during_call' + on_flagged='inject_system_message' as its
invalid-config example; that combination is now accepted, so swap in
the payload/breakdown-missing case and add a test confirming during_call
advisory mode constructs successfully.
* docs(CLAUDE.md): auto-capture review learnings without being asked
This session found three real bugs a human maintainer caught after eight
rounds of bot review and live-proxy verification all missed them. Add a
standing instruction to write learnings.md entries the moment a root
cause is understood, in both the repo-wide file and any relevant skill's
own file, instead of relying on being asked.
* feat(guardrails): add scan_raw_request flag so YAML order can't change enforcement
Maintainer finding on BerriAI/litellm#34940: guardrails for the same hook
run sequentially over one shared, progressively-mutated request dict, so
declaring a masking guardrail before a blocking one hides the violation
from it (200 vs 400 depending purely on YAML order).
scan_raw_request opts a guardrail into always evaluating a snapshot taken
before any guardrail in the hook ran, regardless of its declared position.
Same contract as run_in_parallel: block-only, its own mutations discarded.
Verified live: real proxy, real Gemini call, two custom guardrails (a
redactor then a blocker). Same request, same declared order -- without the
flag the blocker never sees the raw secret (200); with it, the blocker
correctly rejects before any provider call (400).
* fix(guardrails): harden scan_raw_request against review findings
- Use safe_deep_copy instead of a bare deepcopy for the raw-request
snapshot; request payloads commonly carry unpicklable objects (e.g. an
otel span in metadata), which previously raised on every guarded
request when tracing was enabled (Bugbot, High).
- Only compute the snapshot when a guardrail actually opted in, and take
it before _maybe_execute_pipelines runs, so a pipeline-mutated payload
can't hide a violation from a scan_raw_request guardrail outside the
pipeline (veria-ai).
- Log a warning when a scan_raw_request guardrail returns a modified
payload, since that mutation is discarded and the combination is
otherwise silently exploitable for a masking-capable integration
misconfigured this way (veria-ai).
* chore(openapi): regenerate lazy snapshot and dashboard schema types
The lazy OpenAPI snapshot (litellm/proxy/_lazy_openapi_snapshot.json) and
the derived dashboard schema.d.ts had drifted stale relative to the
guardrail config model changes across this PR's rounds (advisory mode,
scan_raw_request, and upstream additions picked up by rebasing).
Regenerated via the CI's own documented fix:
uv run python -m litellm.proxy._lazy_openapi_snapshot
npm run gen:api (via make check)
* chore(openapi): pick up cache_hit_filter field after rebase
* fix(guardrails): stop scan_raw_request warning from firing on every call
_process_guardrail_callback always returns a dict once a guardrail runs
(mark_pre_call_hook_ran unconditionally stamps bookkeeping metadata), so
comparing the result to non-None warned on every request even when the
guardrail never touched the payload. Compare against a bookkeeping-only
baseline instead, so only an actual content mutation triggers the warning.
* fix(guardrails): make scan_raw_request snapshots independent of safe_memory_mode
safe_deep_copy can return the original object under litellm.safe_memory_mode,
or alias a per-key reference on copy failure. Under that mode, the
scan_raw_request comparison baseline aliased raw_request_snapshot (and
therefore the live request), letting mark_pre_call_hook_ran write a
premature execution marker that a deployment-level guardrail sharing the
same name would read as "already ran" and skip. Also affected the feature's
core isolation guarantee: input_data itself could alias the live request
under the same mode. Replace every scan_raw_request snapshot with
_independent_snapshot, which never returns an alias, only a genuine copy
or None.
* fix(guardrails): gate during_call mixed-violation masking behind an actual PII check
The during_call branch for a mixed violation under on_flagged=inject_system_message
unconditionally masked and reassigned data["messages"], even for a pure
prompt-injection violation with zero PII, unlike async_pre_call_hook which
already gates the same call behind _breakdown_has_pii_violation. The
unconditional reassignment touched shared request state during a hook
documented as racing with the concurrent LLM dispatch, for no reason when
there was nothing to mask.
* fix(guardrails): stop scan_raw_request from silently no-op'ing on real requests
_independent_snapshot did one whole-dict copy.deepcopy and returned None on
any failure. Every real proxy request carries data["litellm_logging_obj"]
(a Logging instance nesting a live OTel span with a real lock) by the time
pre_call_hook runs, which can never be deep-copied, so the snapshot failed
on every real request and silently fell back to the live, unisolated data
with no warning -- defeating the entire feature in production while every
existing test (none of which set litellm_logging_obj) kept passing.
Rework the helper to deep-copy each top-level key independently, falling
back to the original reference only for the specific key that fails, same
crash tolerance as safe_deep_copy's own per-key fallback. It never returns
None now; only the keys scan_raw_request actually depends on (messages/
input, metadata/litellm_metadata) need to be genuinely independent.
* fix(guardrails): block during_call when PII can't be safely masked
Greptile finding (P1, security): async_moderation_hook's inject_system_message
branch had no equivalent to async_pre_call_hook's degrade-to-blocking case for
a PII violation on input that can't be safely masked (e.g. combined
messages+input). It fell through to the advisory no-op branch and let raw,
unredacted PII reach the model with no protection at all. Raising still
blocks the response from reaching the caller even though during_call races
with the LLM dispatch, the same mechanism on_flagged="block" already relies
on for this hook, so add the same block-instead-of-advisory branch pre_call
already has.
* chore(lint): fix LIT002 ceiling after rebase merge conflict resolution
* fix(lint): suppress genuine LIT002 hits instead of padding the ceiling
My earlier rebase conflict resolution for type-discipline-budget.json's
LIT002 limit was too low, then overcorrected by padding it well above the
actual measured count. Root-caused instead: _independent_snapshot and the
PATCH-endpoint rollback path legitimately construct plain, mutable
request-payload/config dicts (matching this file's existing precedent for
the same shape), so suppress those four sites with `# mutable-ok:` rather
than reshaping code that must stay a plain dict by contract. Set the limit
to the exact current measured total; the small remaining gap vs upstream's
own committed ceiling is pre-existing drift in litellm_internal_staging
itself (its own tree already measures over its committed limit), not
attributable to this PR.
* fix(guardrails): stamp live request when a scan_raw_request guardrail runs
_run_sequential_guardrail_callback and _run_parallel_pre_call_guardrails only
called mark_pre_call_hook_ran on throwaway snapshot copies for a
scan_raw_request guardrail, never on the live request returned to the
caller. A later async_pre_call_deployment_hook (router-level guardrail
re-check) reads that marker on live kwargs to decide whether to skip
re-running the same guardrail; since it was never stamped there, the
guardrail ran a second time on live data, doubling the external call and
re-applying whatever scan_raw_request's contract says should be discarded.
* fix(guardrails): revalidate Qualifire's on_flagged on live config reload
on_flagged was validated only in __init__. The base
CustomGuardrail.update_in_memory_litellm_params is a generic setattr loop
with no revalidation, so a live config update (PUT /guardrails/{id}, no
restart) could setattr on_flagged="inject_system_message" onto a running
instance, bypassing the constructor's rejection -- silently blocking every
flagged request under an "advisory" label. Mirrors LakeraAIGuardrail's own
update_in_memory_litellm_params override added earlier in this PR.
* fix(guardrails): honor scan_raw_request for pipeline-managed guardrails
A scan_raw_request=True guardrail that is itself a pipeline step never saw
raw_request_snapshot: PipelineExecutor.execute_steps had no way to receive
it, and pipeline-managed guardrails are fully excluded from the normal
sequential/parallel loops that implement the flag. Such a guardrail silently
evaluated whatever an earlier pass_data step in the same pipeline had
already rewritten, defeating the flag for pipeline-managed guardrails.
Moves the snapshot helper (renamed independent_snapshot) from proxy/utils.py
to litellm_core_utils/core_helpers.py so pipeline_executor.py can use the
same independent-copy logic without a circular import, threads
raw_request_snapshot through _maybe_execute_pipelines and
PipelineExecutor.execute_steps/_run_step, and discards a scan_raw_request
step's returned data the same way the sequential/parallel loops already do.
* chore(openapi): pick up upstream drift after rebase onto litellm_internal_staging
* fix(guardrails): stop attempting PII masking during during_call in Lakera v2
Greptile finding (P1, security): during_call runs concurrently with the LLM
dispatch. In the common path, the provider call already binds its messages
kwarg before this guardrail's coroutine gets a chance to run, let alone
before its own network round trip to Lakera completes -- masking here can
never reliably reach the outgoing request, and _apply_redacted_messages_back_
preserving_fields reassigns to a new list object rather than mutating in
place, so even winning the race wouldn't help. This affected both the
PII-only and mixed-violation masking branches, all added in this same PR.
Remove masking from async_moderation_hook entirely and let PII violations
fall through to the normal on_flagged branching: block under "block" or
"inject_system_message" (extending the existing multimodal-only block to
cover every PII case, since masking is proven non-functional regardless of
input shape), log-and-allow under "monitor" -- consistent with how every
other violation type in this hook is already handled.

* feat(auto_router): write and preview the classifier prompt an edited tier set sends
An edited tier set replaces the whole rubric, so the built-in prompt editor is
refused there and the operator had no way to steer the classifier or add
calibration examples of their own. classification_prompt has always been
accepted beside tier_definitions as the rubric's opening; the dashboard just
never exposed it.
Custom mode gets its own Edit prompt dialog bound to that field. The dialog
previews the assembled prompt from the proxy, debounced against the draft, so a
built-in tier that leaves its description blank shows the shipped criteria it
inherits. The preview and the live classifier both call
custom_tier_classification_prompt, verified byte-identical against a running
proxy, so the preview cannot drift from what the router sends.
The preview POSTs on the same path as the shipped GET, because the prompt is the
operator's own text and must not reach access logs through a URL. The path joins
admin_viewer_routes so a role that may call the GET is not refused the POST, and
the request model applies the write gate's own strip and cap so the preview
refuses what the save would refuse.
* fix(ui): name the orphaned keyword rules inside the tier editor before Done
* fix(ui): drop stale classifier prompt preview responses
* style(ui): format the stale preview regression test
The search tool create and edit forms both built a payload carrying
api_base, timeout and max_retries read off form values that neither
zod schema declares, so all three were always undefined. Drop them.
JSON.stringify omits undefined-valued keys, so the request body on
the wire is unchanged.
SearchToolLiteLLMParams and SearchToolInfo in the page's types.tsx
were hand-rolled with a [key: string]: any index signature, which is
why a param could go missing from a form with nothing complaining.
SearchToolLiteLLMParams is now the generated OpenAPI component and
neither type carries an index signature, so the payload builder can
only set params the backend declares.
Also remove a stray ", ]" text node that rendered as visible garbage
next to the connection test dialog's Close button.
* refactor(proxy): move the shared list framework to a surface-neutral package
The list framework and its RFC 9457 problem machinery sat under
management_endpoints/management_v1/, which was the right home while
/management/v1 was its only consumer. The public surface is about to build
on the same framework, and a control-plane package is the wrong thing for a
public route to import.
Moves list_framework.py in full, plus everything in common.py except
MANAGEMENT_V1_PREFIX, to litellm/proxy/list_api/. Every importer is updated
directly instead of leaving re-export shims, so each symbol keeps exactly
one import path. ManagementProblem keeps its name: renaming it would touch
the app-wide exception handler and every call site for no behavioural gain.
The framework's own tests move alongside the code they cover. The fastapi
removed-name guard in test_common.py now globs both packages, so budgets.py
and spend_logs.py stay covered after leaving the framework's directory.
Pure move, no behaviour change: the 179 tests across both packages pass
unchanged.
* feat(proxy): add paginated GET /public/v1/model_hub
The public Model Hub page loads every public model group in one call.
Measured on a live proxy with 300 published groups, /public/model_hub
answers with 328 KB in a single response and the page renders all 300 rows
into the DOM. At a few thousand models that is multiple megabytes and a
page that stops responding, which is what a customer reported.
Adds GET /public/v1/model_hub, the first resource on the unauthenticated
/public/v1 surface. It is built on the shared list framework, so it gets
the {data, meta, links} envelope, RFC 9457 problems, strict unknown and
duplicate query parameter rejection, and sort validation without
reimplementing any of it. Sorting covers model_group, mode, the token
limits and the per-token costs, `q` searches model_group, and the filters
are the ones the page actually offers: mode and providers. Default sort is
alphabetical, which is what a browse list wants and what these rows can
support: they carry no creation timestamp.
/public/model_hub is untouched. The shipped UI still calls it and its
migration is a separate change, so this is purely additive alongside it.
Model hub rows are computed off the running router rather than read from a
table, so this adds InMemoryListExecutor: the same QueryPlan applied in
Python instead of rendered to SQL. It matches the SQL executors where it
counts, NULLS LAST in both sort directions and NULL satisfying no
comparison, so a filter means the same thing on either. The other three
public hubs have the same shape and can reuse it as is.
The fix itself is ordering. The endpoint being superseded reads every
latest health check and joins it against the whole model list, so paging
the response alone would have changed nothing. Here the health lookup is
an injected dependency the executor calls on the page slice, after the
filter and the sort, so it resolves health for the rows being served and
no others. PrismaClient gains a bounded read for that, next to the
unbounded one it mirrors. The regression test pins the ordering by
asserting which model groups the lookup is asked about, and fails against
an enrich-then-slice implementation.
* fix(proxy): address self-review findings on the public model hub list
Five adversarial review passes over the branch. What they found:
`is_null` was the one predicate in the in-memory executor that read a
repeated field's container instead of its elements, so a field holding only
nulls was indistinguishable from a populated one. It now lifts over elements
like every other predicate does. Not reachable through this endpoint, whose
only repeated field grants `contains` alone, but the executor is written to
be reused by the other three hubs and the inconsistency was a trap for them.
The fastapi removed-name guard globbed the framework packages but not
`public_endpoints/public_v1`, which `proxy_server` also imports unguarded at
module level, so the new package had none of the protection the test claims
to give. It now covers all three.
Regenerates the dashboard's API types, which the OpenAPI sync check requires
whenever the proxy's route surface moves. The diff is the 65 generated lines
for the new operation and nothing else; no dashboard code changes here.
Also trims comments and docstrings that argued for a decision or restated a
signature rather than explaining code, and wraps a docstring line that ran
past 120 characters.
* ci: run the relocated list framework tests in the proxy-endpoints shard
The framework's tests moved from tests/test_litellm/proxy/management_endpoints,
which the proxy-endpoints shard claims, into a new tests/test_litellm/proxy/list_api
that no shard named. Both coverage guards caught it: the semantic shards have no
catch-all bucket, so the directory would have run nowhere.
Claims it alongside management_endpoints, where the same tests ran before.
* docs(proxy): stop restating the list spec in the model hub route docstring
The docstring listed every sortable field, the page-size cap and the filter
set, all of which already live in MODEL_HUB_LIST_SPEC and all of which the
endpoint hands back in the allowed array of a rejected request. Two copies of
one spec is a prose update owed on every change to the real one.
Keeps what a caller cannot derive from the endpoint itself: what the resource
is, that it needs no authentication, and a working example. Regenerates the
dashboard types, which carry the docstring as the operation description.
* fix(proxy): reject a repeated sort field instead of sorting by it twice
sort took any number of comma-separated keys, and the in-memory executor runs
one full sorted() pass per key before slicing. Naming one allowed field N times
therefore bought N passes over every published model group, synchronously on the
event loop, from a route that needs no credentials. Measured on 300 groups:
0.001s for one key, 0.034s for a thousand, 0.166s for five thousand, and it
grows with the catalogue this endpoint exists to make large.
A repeated field cannot change the ordering, so rejecting repeats costs a caller
nothing and bounds the passes at len(sortable), a number the spec author picks
rather than the caller. That beats an arbitrary cap: no magic number, and the
bound holds for every resource built on the framework.
The tiebreaker is appended after parsing, so sorting explicitly by it stays legal.
Budgets renders one ORDER BY in SQL and never had the amplification, but the
check belongs with the rest of the sort validation rather than in one executor.
* fix(proxy): make the search disjunction one level deep by type
Two CI gates, one cause. AnyOf declared its clauses as Predicate, so both
consumers had to recurse to evaluate one: the SQL renderer through
_render/_render_all, and the in-memory executor through _holds. The recursion
detector flags the latter, and its reason is the same one this PR already ran
into once, a caller-controlled cost that shows up as CPU.
Nothing actually builds a nested AnyOf. _search_predicate is its only producer
anywhere in the repo and it emits Compare leaves, in every call site and every
test. Declaring clauses as tuple[Compare, ...] makes that a fact the type
checker keeps rather than a comment, and _holds then evaluates a disjunction of
leaves with no recursion at all.
Also marks the new health read's broad except, which the strict gate counts,
and covers the ordering comparison operators. The endpoint exposes only
eq/in/contains, so gt/gte/lt/lte were live code no test evaluated.
* fix(proxy): keep the new health read inside the type-discipline ceiling
The bounded health query added ten LIT002 violations, which pushed the
codebase total past its budget. The gate counts across the tree and compares
to the merge base, so a file already carrying debt does not absorb new
violations.
Returns an empty tuple rather than an empty list on the two no-result paths:
the signature already promises a Sequence, so that is a free two-violation
reduction and a better type. Builds prisma's order argument from a tuple of
pairs, which turns four literals into one. The three that remain are prisma's
own API shape and each carries its reason.
Both budget gates now pass against the merge base.
* fix(proxy): clear the two basedpyright errors the new route added
The type-check budget is over its ceiling on the base already, so the gate
blames any increase: reportArgumentType 2574/2564 and reportPrivateUsage
1815/1808, one each, both from this file.
fastapi types a route's tags as list[str | Enum], so the tuple was an argument
error; budgets.py has the same one and it is part of what put the rule over.
Passing a list is what the signature asks for, marked because an inline list
is a construction the discipline gate counts.
_get_model_group_info is private by name but is the shared reader the endpoint
this supersedes imports the same way, so the import carries a rule-scoped
ignore with that reason rather than a copy of the function.
basedpyright now reports zero errors across both new modules, and all three
budget gates pass against the merge base.
* feat(ui): edit the auto-router tier set with custom classifier-defined tiers
The editor over the model layer beneath it. An Edit tiers button turns the tier
list into an editor: a tier takes a name, a classifier definition, and models,
between two and eight rows. Restore defaults resets to the built-in four rather
than stacking them on top. Keyword rules follow a rename, an orphaned rule
blocks the save, and both forms dry-run the exact payload against the backend
validator before writing.
The edit modal hydrates a stored custom set into rows, and an untouched
open-and-save round-trips byte-identically, per-model reasoning efforts
included. A form that never opens the editor submits the same bytes as before.
The cost-optimization tier chart renders arbitrary tier names: the guard that
returned no models for a non-built-in name is gone, and the fixed four-color
array gives way to the shared cycle.
* refactor(ui): extract tier editor sections to clear new lint warnings
* test(ui): drop narration comments per repo convention
* fix(ui): default editingTiers so the build's type check passes
* fix(ui): restore the mid-dry-run submit guard and its regression tests
* feat(spend): report prompt caching savings as total and gateway-attributed
`prompt_caching_savings_spend` credited every cached request, including caching a
client asked for with its own `cache_control` and caching a provider does implicitly,
so the number overstated what the gateway had any hand in.
Gating that column in place would have fixed the overstatement by changing what the
column means, leaving rows written before the change saying "all caching savings" and
rows after saying "gateway-injected only" with nothing to tell them apart, and forcing
a decision about rewriting history. It also breaks the cache-leakage estimate on the
dashboard, whose numerator would be gated while its denominator, the cached token
counts, would not, so the rate it extrapolates from would be quietly diluted.
Report both instead. `prompt_caching_savings_spend` keeps meaning every net dollar
caching saved, which is what a customer means by "what did caching save me", and the
new `gateway_injected_caching_savings_spend` carries the subset litellm caused by
injecting the breakpoints itself. Both are derived from the same marker, so this
changes what is done with it rather than how it is obtained.
The attributed figure is normally the smaller of the two, being a subset of the same
requests, but not always: a request that writes cache it never reads has negative net
savings, and excluding such a request can lift the attributed figure above the total.
Also stops the marker riding into a fallback leg. The fallback rebuild spread the
failed attempt's metadata forward, so a deployment that injected nothing inherited the
marker and was credited anyway, which silently restored the very overstatement this
separates out.
* fix(bedrock): credit gateway caching where the tool cachePoint is placed (#38478)
The savings marker records breakpoints litellm placed, and a tool_config
injection point becomes one only in the converse transform, and only when the
request carries tools. The prompt hook cannot see either condition, so marking
on the point's presence credited request shapes that cached nothing, while
Bedrock tool caching the gateway did cause went uncredited.
Record it at the placement site instead. The marker's reader also resolves its
bucket by value now: litellm_params declares litellm_metadata as None on every
request, so asking the shared name resolver named a bucket that was not there
and the mark was dropped.
A coding agent names each conversation by quoting the whole session and asking
for a title. The classifier rated the quoted session rather than the request, so
the cheapest call the client makes routed to the most expensive tier: 11 of 17
title generations in one day of real traffic came back COMPLEX.
Recognize those prompts by literal sentinel on the newest ask and route them to
the cheapest configured tier without classifying them, so the call costs nothing
to route. The placement is scoped to the one request that carries the sentinel:
it never displaces an operator's classifier plugin, the bandit cannot reach above
the tier as raised, it never becomes the session pin, and the sentinel that
matched is recorded on the routing decision. Detection reads the newest ask
alone, so a title request quoted into a later turn cannot cheapen the work that
follows it, and a keyword rule, an escalation keyword or the plan-mode floor all
still decide over it.
Regenerates the lazy OpenAPI snapshot, which was already stale on the base for an
unrelated Presidio guardrail field and failed the schema check on every PR.
Resolves LIT-6349
The Blog trigger carried `bg-transparent!`, which emits an important
background-color and so beat the non-important `hover:bg-accent` the shared
product-link class supplies. Docs lit up on hover and Blog stayed flat, the
same Docs/Blog inconsistency this branch is about on a different axis.
Dropping the override lets the shared hover through. `border-0!` stays, since
it keeps the trigger's box identical to the plain Docs anchor. Verified in the
browser: both now paint lab(96.1596 -0.0823438 -1.13575) on hover at 36px tall.
Docs went from a ghost Button to a plain anchor, which dropped the focus
treatment the Button was supplying, so tabbing to Docs showed nothing while
tabbing to Blog showed a ring. The ring now lives on the shared class both
sides use, matching the Button primitive's values.
Kept Docs as a real anchor rather than routing it back through Button:
nativeButton={false} stamps role="button" onto the element, so the old
DashboardHeader markup announced Docs as a button and lost its link
semantics. Tests pin both the ring and the link role.
* feat(ui): the model and wire layer for operator-defined auto-router tier sets
The data half of the custom tier set editor, with no visible UI change: the
editor lands separately on top of it.
One reader, activeTierRows, mints built-in rows with the canonical tier key as
their id, so the fallback pointer, the plan-mode floor and the per-model params
are row ids in both modes and nothing downstream branches on the mode. One
restrictions table carries each forbidden setting beside the reason shown for
it, so the greyed control and the omitted payload key cannot disagree. The
tier-set writes live in applyTierSetAction, where the fallback re-point and the
floor turn-off happen in one commit, unit-tested without a render.
buildComplexityRouterConfig emits tiers, tier_definitions and fallback_tier from
the rows, forces the LLM classifier, and strips what the backend rejects beside
tier_definitions. A payload built without a custom tier set is byte-identical to
what the form sends today.
* fix(ui): resolve frontend-lint failures on the tier-set model layer
* test(ui): drop a redundant explanatory comment per repo convention
* fix(ui): keyword rules follow their tier row through every tier-set action
The endpoint built messages=[{"role": "user", "content": prompt}], so a dry run
could not carry prior turns, the caller's system prompt, or the tool definitions
a request advertises. A real agentic turn reduced to its last sentence classified
as trivial, which is why a config sweep reported savings for every configuration.
Accept messages, system and tools, and forward them to the same pre-routing hook
untranslated, with the raw-body snapshot built by the serving path's own owner,
refresh_proxy_server_request_body_snapshot. Loose types are deliberate: the hook
reads whatever dialect the surface produced, so validating against one surface's
schema would reject the others.
prompt stays as the single-ask shorthand, normalized into one user turn inside the
request model so the handler carries no mode branch.
The top bar's theme control needed a click on the sun/moon, then a menu, then
a choice, to do something every other product does in one click. It is now a
plain button that flips between light and dark, with the beta marker moved into
the label of the click that turns dark on. An explicit "system" choice is gone,
but next-themes still follows the OS for anyone who has it stored and has not
clicked yet.
Docs and Blog also drifted apart in the gateway header: Blog rendered through
the shared product-link class while Docs was a muted ghost button one size
down, so Docs read as dimmer and sat 4px shorter. Both now go through a shared
DocsLink component, which is also what the legacy navbar uses, so the pair
cannot drift again.
* fix(guardrails): add fail-open mode to CrowdStrike AIDR guardrail
Add a fail_on_error param (default True, preserving existing behaviour) to
the CrowdStrike AIDR guardrail, mirroring model_armor and generic_guardrail_api.
When fail_on_error=False the guard fails open only on server errors (5xx) and
connectivity failures, so the request proceeds unmodified. Caller-controlled
4xx responses and result.blocked policy blocks always fail closed. The
applied-guardrails header is recorded even on the fail-open path.
* fix(guardrails): fail open AIDR 4xx
* refactor(guardrails): isolate AIDR fail-open
* style(guardrails): format AIDR fail-open
* ci: satisfy unit workflow timeout invariant
* refactor(guardrails): accept AIDR mappings
* test(guardrails): inject AIDR HTTP client
* fix(guardrails): harden AIDR fail-open against delivered verdicts and record fail-open status
Reads the blocked verdict from the raw body before guard_output validation so schema drift or a changed verdict type cannot fail open past a delivered block. A transformed response that cannot be parsed fails closed so delivered redactions are never dropped. Fail-open runs record guardrail_status guardrail_failed_to_respond with timings instead of success. Restores the fail-open behavior tests dropped mid-PR and reverts the payload Mapping widening
* test(guardrails): cover fail_on_error wiring and fail-closed default for CrowdStrike AIDR
* chore(guardrails): annotate the transformed-drift detail payload for the LIT002 budget

* feat(ui): dry-run an auto-router config against the backend before saving it
Both auto-router forms built a payload and posted it, so anything the write gate
refused came back as a raw 400 with the backend's message buried in it. They now
POST the exact payload to /auto_router/validate_complexity_router_config first
and surface its verdict inline.
One dryRunRejection owns the gate, and it reads valid alone. The verdict's two
fields arrive independently, so gating on the error message would let a rejection
that carried none through to the write. A transport failure fails open as valid,
leaving the write gate authoritative rather than blocking a save on a flaky
network.
Applies to every auto-router, built-in tiers included.
* fix(ui): hold the auto-router create closed for the full dry-run and create sequence
A second submit while the dry-run round-trip was pending started another
create against the non-idempotent /model/new. The submit handler now
refuses re-entry and the button disables for the whole sequence, matching
the edit modal's loading guard. Also drops the explanatory comments this
PR had added.

The bundled-path check was an unanchored substring match, so a
user-supplied logo URL that happened to carry /assets/logos/ or
/_next/static/media/ in its path, and whose filename collided with one of
the 36 manifest entries, would pick up a dark-mode treatment meant only
for assets we ship.
assetPaths already draws this line for resolveLogoSrc, which returns an
external src untouched. Export that predicate instead of writing a second
one, and require a treated src to clear it.
The existing test only covered a remote URL with a bare filename, which
passed either way. The new ones fail without the guard.

Two lazily loaded models changed without their generated artifacts being
regenerated, so check-ui-api-types has been red on every branch off staging.
The snapshot that /openapi.json serves for unloaded features was missing
ChatCompletionToolReferenceObject, and the dashboard types were missing
aws_external_id. The snapshot step runs first and short-circuits, so only the
first one was visible until it was fixed.
Both files are regenerated with `python -m litellm.proxy._lazy_openapi_snapshot`
and `npm run gen:api`, no hand edits.

The dashboard's dark theme left a chunk of the bundled provider logos
unreadable: 25 of them are pure black marks on a transparent background,
so on a near-black surface they disappeared entirely, and another 11 are
dark multicolor marks drawn for a white page.
This adds the seam the rest of the work hangs off: a per-asset treatment
manifest in logoTreatments.ts, and a Logo component that applies the
treatment it names. Two treatments exist today. "invert" flattens a mark
to solid white with brightness(0) invert(1), which is what the vendor's
own white mark looks like for a pure-black transparent glyph. "plate"
puts a white surface behind the mark so it reads exactly as it does on a
light page.
Both are dark-only, and only assets named in the manifest are touched, so
light mode is unchanged and the other 96 bundled logos keep rendering
byte for byte as they do today. The className an untreated logo receives
is passed through verbatim rather than routed through cn(), so even the
class string is unchanged.
The split between invert and plate was measured per asset, not guessed:
luminance, saturation and alpha coverage sampled off a canvas render. Two
assets that look monochrome, aiml_api and repelloai, carry a light
knockout inside dark artwork, so inversion would flatten the knockout
into the mark and erase it. They get a plate instead, and a test pins
that.
Six assets whose artwork is an opaque dark box (aim_logo, aim_security,
deepgram, jina, lakeraai, openmeter) are deliberately left untreated. A
plate cannot show through an opaque image, so the only honest fix for
them is a replacement asset.
Two loading/empty transitions the disabled empty state got wrong.
A selection made in a range that had options survives a move to a range that
has none, and it still scopes the data below, so disabling the combobox
outright took away the only control that could clear it. Disable it only when
there is nothing selected to clear.
The customer list defaulted to an empty array while its query was in flight,
so the filter announced a range with no customers before anything had been
read. Leave it undefined until the query resolves, as the tag list now does.
Changing the date range left the previous range's tags in state until the
new request landed, so the filter either offered tags that range no longer
has or, when the old range was empty, stated "no tags" about a range nobody
had measured yet.
Stamp the fetched list with its range key and select it during render, the
same way the request tiles above already guard against a superseded range.
Clearing in the effect would be a render too late.
The usage page seeded its tag list as an empty array, so between first
paint and the tag request landing the filter had a resolved-looking empty
list and showed "No tags with usage in this range" for a scope nobody had
measured yet.
Seed it as null instead, which the filter already treats as unresolved and
hides, so the empty state only appears once the list has actually come back.
The tag usage filter was removed from the DOM whenever the tag list came
back empty, so an internal user whose traffic all runs through team keys
saw a blank Tag Usage panel with no filter and no explanation. Their scope
is legitimately empty, but the page gave them no way to tell that apart
from a broken or gated feature.
Render the filter whenever the entity list has resolved, disabling it and
swapping in an entity-specific empty message when there are no options.
A still-unresolved list keeps hiding the control as before.
An MCP server behind an API gateway needs two credentials on one request: the
gateway's own token on a private header, and a separate bearer on Authorization
for the server behind it. Every arm that minted or held a token hardcoded
Authorization, and the conflict rule then dropped the operator's static
Authorization to make room, so the second credential never arrived.
ApiKeyConfig already modelled this as header_name plus value_prefix behind a
header() method. Extend that carrier to the four minted-token configs, have each
resolver arm ask its config which header to use instead of naming one, and drop
only the header the resolved credential is about to occupy.
Operators set it per server via upstream_token_header, plumbed through
config.yaml, the credentials blob, the management API and the admin form, on the
M2M, token-exchange, authorization-code and ID-JAG arms. It is non-secret so it
stays plaintext and round-trips on admin reads. Unset keeps today's behaviour.
Moving a credential off Authorization means it stops inheriting what Authorization
gets for free, so the slot now carries those protections itself. httpx drops
Authorization when a redirect crosses origin and keeps every other header, so a
custom slot is dropped by the client on the same condition, mirroring httpx's own
scheme/host/port rule with an agreement test that fails if the two ever diverge.
The v1 path also mirrors the v2 conflict rule, so an injected header cannot shadow
the credential the gateway resolved for that slot.
Which header a credential occupies, and what counts as being that header, was
answered independently in nine places by four hand-rolled comparisons. same_header,
has_header and without_header in litellm/types/mcp.py are now the one owner, shared
by both MCP stacks, and the client derives its slot once instead of three times.
The header name reaches egress verbatim, so the RFC 7230 grammar lives in one
place and is checked where servers are built: a bad value fails the config load
and the management API returns 400, rather than raising while a spec is built
and emptying the aggregate tool list for every other server. A blank means unset,
matching what the endpoint already accepts.
Migrate the create-key user picker, add-member user search, and usage team filter onto the shared paginated selects, gate the logs error-code filter on input reasons, and add clearAllLabel, autoHighlight, and aria-required passthroughs the migrations need.
Select the picked label on focus and snapshot whether the pre-edit selection covered the whole input; when it did, the next input value is a full replacement, so skip the typedInsertion diff that mangles pastes sharing a prefix or suffix with the label.
* fix(ui): let the paginated search select keep what the user types
The combobox handed Base UI a freshly built option object for the current
selection every time a page of results came back. Base UI answers a changed
value by rewriting the input with that option's label, so every search response
wiped the query mid-typing and the list never narrowed. Once a user had been
picked in the Usage page filter box, no other user could be reached.
The component now owns the input text. It holds the query while the list is
open, falls back to the selected option's label once the list closes, and
remembers the picked option so its label survives later pages that no longer
carry it, the way the multi-select sibling already does.
* refactor(ui): name the paginated select's search state instead of commenting it
* fix(ui): start a fresh query when typing lands on the selected label
Focusing the filter box without clicking it leaves the caret at the end of the
selected option's label, so the next keystroke extended that label into a query
no server could match. Only a click cleared the box first.
A keystroke that arrives while the box is showing a label is now read as the
start of a new query, wherever in the label it landed.
The shared SelectContent wrapper defaulted alignItemWithTrigger to true,
which puts Base UI's positioner into item-aligned mode and places the
popup so the active item sits on top of the trigger. In that mode the
side and sideOffset the wrapper passes two lines above are ignored, and
the popup reports data-side="none".
The overlap only becomes visible once the items are tall enough to
matter, which is why the autorouter Template picker shows it clearly:
its options are three-line cards, so the popup covers both the select
box and its own label.
No call site in the dashboard asked for item-aligned mode. 21 of them
across 15 files already passed alignItemWithTrigger={false} by hand to
undo the default, and the remaining 127 inherited the bug. Flipping the
default makes side and sideOffset live, so collision handling works and
a select with no room below now flips above the trigger rather than
covering it. The 21 hand-written opt-outs are deleted as redundant.

The preset put Fable 5 in REASONING, sitting above Opus in a Haiku to Sonnet to
Opus ladder even though Fable is the lighter model. Run Opus 5 there instead, at
high thinking, so the tier above COMPLEX is the same model thinking harder rather
than a different and lighter one.
This is the first bundled preset to carry tier_model_configs. The round trip was
already built and unit tested, but nothing between the bundled JSON and the
create payload asserted on it, so add that coverage here.
