The generic 400 branch of the OpenAI exception mapper dropped the wire body and no
branch carried the response headers, so an application calling a LiteLLM proxy through
a litellm_proxy/ model could not tell a guardrail block from any other failure without
walking __cause__. BadRequestError now takes headers, filled for a litellm_proxy
upstream, and the generic branch passes the body. The proxy edge treats the literal
"None" type and param an older proxy sends as absent and stops forwarding an upstream
proxy's date and server headers.
Key objects share the 200-entry UserApiKeyCache in-memory store with teams,
end users, tags and memberships, so churn in those objects evicts hot keys
and forces a LiteLLM_VerificationToken lookup on the next request. Route
bare hashed-token keys to a dedicated InMemoryCache inside UserApiKeyCache
while keeping Redis, TTL, serialization and invalidation shared

The release image installs only the proxy extras, and psutil is a locust and mirakuru dev
dependency, so /debug/memory/summary answered with an error and no ram_usage_mb on the e2e
gate. Fall back to /proc/self/statm and /proc/meminfo on Linux when psutil cannot be imported
On the release gate the e2e tests only see the nginx router, and the chart's
ingress sent /debug/memory/summary to the backend catch-all, so the RSS check
measured the backend pod instead of the gateway workers that serve the failing
requests. Render it as an Exact gateway path next to /test, name the host in the
summary response so workers behind one origin never collide on pid alone, and
key the harness readings by (origin, hostname, pid)
The cascade zeroed end-user spend with a single update_many whose where
clause enumerated every dependent user id. Prisma compiles that IN-list
into one prepared statement carrying one bind variable per customer, and
PostgreSQL caps a statement at 32,767 of them. Once a shared budget had
more dependents than that the statement could not be parsed at all, so
the atomic cascade rolled back, budget_reset_at never advanced, and the
tier stayed due on every later tick forever. Customers sitting at their
cap were blocked indefinitely with only a recurring log line to show for
it.
End users now match on budget_id like every other gated table, plus a
NULL-budget_id branch for the implicitly created rows that carry no link
and ride the default tier. The statement's bind count now tracks the
number of expiring tiers rather than the customer population, so a reset
costs the same whether a budget has ten dependents or a million.

* feat(rust_bridge): count budget-check input tokens in Rust on all LLM routes
Rust counts input tokens from the raw JSON body with the GIL released inside the existing budget reservation, covering every LLM route the auth dependency guards. It only fires for models on the Anthropic tokenizer when a budget is set, and Python counts whenever Rust is off, missing, or declines a body shape.

* perf(rust): count byte-level BPE tokens without the GPT-2 split regex (#40594)
The oniguruma run of the ByteLevel pre-tokenizer regex is about 90% of
encode_fast on a 100k token body (100 ms of the ~110 ms Rust admission
count in the gateway pod). A hand-written scanner that yields the same
pieces, then feeds the model directly, counts the same text in 10 ms.
It only engages for tokenizers with the Anthropic shape (optional NFKC,
ByteLevel without prefix space, no post-processor) and falls back to the
full encoder when the text contains an added token. Parity with
encode_fast is tested on random texts, the pieces are compared with the
real pre-tokenizer, and the \p{L}/\p{N}/\s tables are checked against
oniguruma for every code point.
NFKC runs through unicode-normalization-alignments, the crate and
Unicode tables NormalizedString::nfkc already uses, so the fast path
normalizes exactly what the full encoder would. Using the newer
unicode-normalization crate changed the count for 171 code points that
gained compatibility decompositions after Unicode 9 (U+32FF, U+A7F1..).
The fast normalizer is compared with the tokenizer's for every scalar
value and on random texts.
The scanner is built without mutable state: byte_char and mapped_len replace the const table builders and the reusable mapped buffer, and iter::successors replaces the stateful piece iterator. byte_chars_match_the_byte_level_alphabet checks the byte mapping against ByteLevel for every scalar value.

* feat(guardrails): map each guardrail scan id to its guardrail, stage and provider
Adds the x-litellm-guardrail-scan-metadata response header, a JSON list of
{guardrail, stage, provider, scan_id} entries, next to the existing
comma-separated x-litellm-guardrail-scan-id header. Prisma AIRS records the
execution stage for every scan and OpenAI Moderation now records its
moderation id too. The new metadata key is internal: client-supplied values
are stripped and it is exposed through the UI CORS allow list.

error_status_code only read status_code, so a ProxyException raised
before routing (which stores its status as the string code) answered
500 with its 4xx type through the rerank, images, realtime, files, and
pass-through tails. It now falls back to a decimal code. A 408 maps to
timeout_error instead of invalid_request_error.
Tail regressions for rerank, images, realtime calls, and the chat
pass-through fail at the merge base with ('None', 'None'); the new
files-test helpers are fully typed.
* fix(proxy): load db credentials inside the model reconcile so a worker never serves a model before its credential
* fix(proxy): load db credentials in the model read-through so a request miss never adds a model before its credential
* fix(proxy): read credentials from the writer db before the router update and look a credential up once
* test(proxy): assert the credential is loaded when db models reach the router instead of the call order
An include entry that matches both a file next to the config that declares it and
one next to the root config now warns naming both, so a config that resolves to a
different file than it used to says so instead of quietly serving other models.
Also from reviewing that change:
- an empty root object in a bucket fails the boot again instead of coming up empty
- a YAML syntax error in a bucket object logs its own line naming the object
- an include already loaded is skipped before it is read rather than after
- reading a config out of GCS builds the plain bucket client, so it needs no
enterprise license and starts no flush loop that nothing ever cancels
Keep reading an include left beside the root config, with a warning naming where it
was found, so a nested include written against the old rule still boots.
Also build one S3 client per config load rather than one per included object, treat an
empty included object as an empty config instead of failing the boot, and point the
error a dropped bucket include raises at the bucket error logged with it.
Reading a config from a bucket ran a blocking boto3 GET straight from the
event loop for every object in the include tree, and on GCS it built a new
bucket client per object, each one starting a flush task that never ends.
S3 reads now go through a worker thread, and one bucket client serves the
whole include tree.
A config loaded from a GCS or S3 bucket skipped include processing entirely,
so every model, guardrail, and setting behind an `include` was silently
dropped. Both bucket types shared the same branch in `get_config`, which
never called `_process_includes`, and that helper only ever read from disk.
The merge now lives in one async helper that takes the loader as a
dependency, so disk and bucket configs share the same semantics: list values
extend, everything else overrides, nested includes are followed, and the
`include` key is stripped. Bucket entries resolve as object keys relative to
the config object's prefix, with a leading `/` meaning the bucket root, and
an include that cannot be read now raises instead of being skipped.
_numeric_form_type only peeled a single ReadOnly layer, so a field still
wrapped in Required/NotRequired was read as non-numeric and dropped from the
mapping. Which qualifiers survive get_type_hints varies by interpreter version
and by include_extras, so on Python 3.10 NotRequired[ReadOnly[int]] reached the
check intact and the field was silently skipped, which is what turns the mapped
test red on the 3.10 leg only.
Peel Required/NotRequired/ReadOnly/Annotated in any order and nesting instead.
The one production caller feeds a schema with no qualifiers, so the resulting
mapping is unchanged on every interpreter in the matrix, but a field written the
house-convention way stops being dropped.
The proxy's exception tails defaulted `type` and `param` to the four-character
string "None", which is neither a known OpenAI error type nor the JSON null the
nullable `param` field is typed as, so a client's error handler matched nothing
and fell into its generic branch.
Lifts the helpers PR #39521 added for the unified LLM endpoints into
litellm/proxy/common_utils/openai_error_payload.py and calls them from the file,
rerank, image, realtime, anthropic, and pass-through route families, plus the
shared handle_exception_on_proxy handler that the management, batches,
fine-tuning, credential, SCIM, guardrail, and customer routes funnel through.
The remaining families (proxy_server, auth, health, spend tracking, and
management endpoints) follow in separate PRs so each slice stays QA'able on a
live proxy.
Every field of a multipart form arrives as a string, so `n` reached the
provider as "2" and Bedrock Nova Canvas rejected the request with
"expected type: Number, found: String". Restore the type the request
schema declares at the boundary where the form is parsed, driven by the
schema's own type hints so the helper covers any int- or float-typed
field on any multipart endpoint.
A model access group could gate which models a caller reaches but never how
much that group of callers could spend in total. Capping a shared pool meant
setting a per-entity budget on every key by hand, which caps each key
separately and still leaves no way to read what the group cost.
Spend is attributed to a group only when the group's name appears on an
allowlist the caller was granted (key, team, team-member scope, project or
org) and that group serves the requested model. Asking for a model that
merely belongs to a group attributes nothing, because nothing about the
caller named the group. Levels are unioned rather than ranked, so a team
granted "*" whose member is scoped to one group still counts as gated by
that group.
Enforcement runs on both paths tags already use: a reservation counter on
the pre-call path and a read-time max_budget check inside the existing
concurrent budget gather, so the ceiling still holds under
disable_budget_reservation.
Adds LiteLLM_ModelAccessGroupBudgetTable, which is the only place a group is
ever a row: the groups themselves stay free-text strings in
model_info.access_groups, so a row exists only once someone gives that group
a budget. GET, PUT and DELETE /access_group/{name}/budget manage it, and
/access_group/{name}/info now carries the spend and budget alongside the
models.

is admin-set key/team callback_vars, with LANGFUSE_TRACING_ENVIRONMENT
as the deployment-wide fallback.

* fix(langfuse): validate langfuse_environment, avoid redundant clients, honor it in langfuse_otel
Closes the review gaps on the langfuse_environment param:
- Validate values against Langfuse's environment pattern at save time
(/key/generate, /key/update, /team callback all 400 on e.g. 'Production'
instead of 200-then-silently-dropping every trace server-side) and at
logger init; non-string values are str()-coerced instead of crashing
the SDK's regex check per event.
- Treat empty/whitespace values and values equal to the deployment-wide
LANGFUSE_TRACING_ENVIRONMENT as non-dynamic so an environment-only
override that changes nothing no longer mints a duplicate SDK client
against MAX_LANGFUSE_INITIALIZED_CLIENTS.
- langfuse_otel now reads the per-key/team langfuse_environment from
standard_callback_dynamic_params instead of only the env var.
- Advertise the param on the discovery surfaces: callback_configs.json
(langfuse + langfuse_otel), the dashboard callback registry, and the
/team/{team_id}/callback docstring (schema.d.ts regenerated).

* fix(proxy): reset a stuck team member's budget
A per-team-member budget check reads a cross-pod spend counter that
nothing ever invalidates. Once a member exceeds their per-member
budget, resetting the key's spend, raising the user's or the team's
own budget, or issuing a new key all leave the member stuck, because
none of them touch this counter or its cached membership object.
Add POST /team/{team_id}/member/{user_id}/reset_spend to reset a
member's tracked spend, and invalidate the same cached state from
/team/member_update when it raises a member's own budget, so that
path also takes effect immediately instead of waiting on the
membership cache's TTL. Name the entity in the check's error message
so a stuck member is diagnosable from the 429 body alone.

Every repository handed its `.table` back untyped, so a dozen modules had
each grown a private `_PrismaTableActions` Protocol to paper over it. They
had drifted: some declared `update` as returning the row, others the row or
None, and none agreed on whether `find_many` was covariant
Replace all of them with a single `TableActions[RowT_co]` in
`litellm/repositories/prisma_protocols.py`, keyed to the prisma row each
repository is bound to. Query inputs stay `Mapping[str, object]` so callers
keep passing plain dicts, and `find_many` returns `Sequence` so the row type
stays covariant
Typing the nullable returns honestly surfaced paths that were already
crashing. A team admin could never edit or delete a memory entry owned by
their team: the write-auth check fed a raw prisma row to a helper that
expects the domain model, so `members_with_roles` arrived as plain dicts and
the request died as a 500 instead of applying the edit. Non-admin members hit
the same 500 in place of the 403 they were owed, so refusal and breakage were
indistinguishable. `/v2/model/info?user_models_only=true` dereferenced a
missing user row rather than returning the 400 the route already had, three
team routes dereferenced a team deleted between the read and the write, and
the agent registry dereferenced a missing agent instead of naming it
