file uploads to litellm_proxy deployments Uploads for the Batch API through a deployment that points at a second LiteLLM proxy arrived downstream as bare multipart requests with no model or target_model_names, so the second proxy could not route them and fell back to files_settings or the wrong endpoint shape. The router now injects target_model_names into extra_body when the deployment provider is litellm_proxy, and litellm_proxy is registered as an OpenAI-compatible files/batches provider so the downstream call uses the deployment api_base and api_key over the OpenAI wire format.

Cursor Agent Date: Thu, 30 Apr 2026 17:47:18 +0000 Subject: [PATCH 010/147] feat(proxy): proactive model deprecation alerts and /model/deprecations endpoint Surfaces deprecation_date metadata that is already shipped in model_prices_and_context_window.json so operators get lead time to migrate before a provider sunsets a model. - New helper litellm.proxy.common_utils.model_deprecation classifies the router's configured models into deprecated / imminent / upcoming buckets. Resolution order: explicit model_info.deprecation_date > model_info.base_model > litellm_params.model. - New GET /model/deprecations (and /v1/model/deprecations) endpoint returns a ModelDeprecationResponse, gated by user_api_key_auth. - New AlertType.model_deprecation_warnings (in DEFAULT_ALERT_TYPES) plus SlackAlerting.send_model_deprecation_alert dispatches a Slack message for deprecated/imminent models. Severity is High when any model is already past its date, Medium when only imminent. - ProxyLogging.startup_event schedules a daily background task (_run_scheduled_deprecation_check) when the alert type is enabled. The interval is configurable via LITELLM_MODEL_DEPRECATION_CHECK_INTERVAL and the warn window via LITELLM_MODEL_DEPRECATION_WARN_DAYS. - Tests: 16 unit tests for the helper plus 4 for the Slack hook in tests/test_litellm/.

From 2d7350412440f07535768bc6b7bc522bf55bc678 Mon Sep 17 00:00:00 2001 From: Cursor Agent Date: Thu, 30 Apr 2026 17:51:54 +0000 Subject: [PATCH 011/147] fix(model_deprecation): drop env-var overrides to satisfy docs validation The proxy documentation lives in BerriAI/litellm-docs and any new env key flagged by os.getenv() must be added there before the test_env_keys.py CI check passes. Rather than fork the docs repo for two niche tunables, hard-code the defaults: - DEFAULT_DEPRECATION_WARN_DAYS = 30 (already overridable per-request via ?warn_within_days=N on /model/deprecations). - DEFAULT_DEPRECATION_CHECK_INTERVAL_SECONDS = 24h. Both can still be raised as env-var follow-ups together with their docs update if operators ask for it.

Resolving deployment pricing through it therefore reported a free deployment for any ordinary one, which priced its batches at $0 while usage stayed correct: the same silent under-count this branch set out to remove, widened from bedrock to every provider. Caught by a live batch run, where four vertex batches that price correctly today came back at $0. The raw registration is now what decides: pricing is used only when the deployment actually declares one of the batch cost fields, so ordinary deployments fall back to the global cost map exactly as before.

Layering declared rates over published ones made this reachable: a deployment declaring only a zero batch rate previously kept a fabricated zero on the standard field, which happened to bill nothing. The two batch fields are now gated on presence. Verified no cost-map entry changes behavior: the only three carrying a zero batch rate are embeddings, whose standard output rate is also 0.0, so both paths yield the same zero.

affordance, then return with that promise still in flight. When the worker outlives the file's jsdom environment, the component's setIsLoading(false) runs against a torn-down window, and React reports "ReferenceError: window is not defined" as an unhandled rejection. Vitest counts that as an error, so ui-unit-tests fails the job while reporting every one of its 7351 tests as passed.

Adds an "Advanced scoring" panel to the classification section, shown whenever the scorer actually runs: on a heuristic router, and on an LLM classifier that falls back to the heuristic. An untouched knob is omitted from the payload, so a router keeps tracking the shipped defaults instead of freezing today's numbers. The three keys join MANAGED_COMPLEXITY_ROUTER_KEYS, so the edit modal now rebuilds them from form state rather than carrying the stored copy through. That makes hydration load-bearing, and it hydrates an absent knob to undefined rather than to the defaults, so an untouched save cannot pin a router that was tracking them. The "How Classification Works" card now reads the configured boundaries instead of hardcoding 0.15 / 0.35 / 0.60, which would otherwise start lying the moment an operator changed them. * test(complexity_router): pin the dashboard scorer defaults against config.py The Admin UI keeps its own copy of the boundary, threshold and weight defaults to prefill its controls. The copy is display only, since an untouched knob is omitted from the payload, so drift shows a stale placeholder rather than pinning a router. Nothing caught that drift before, and a blank or dead control is worse, so the two copies and the dimension key set are pinned against each other here. * fix(ui): surface out-of-order scorer thresholds as an error, not a hint Boundaries that decrease make the tiers between them unreachable, which silently changes where traffic goes, so amber body text undersold it. Saving stays allowed: a router configured this way in config.yaml would otherwise become uneditable in the UI for every unrelated change. * fix(test): search the default-model picker instead of trusting option order The pinned model is appended after every model the presets contribute, and that list has reached 11, so the option fell outside the virtualized dropdown's rendered slice and the two default-model-pin cases failed on staging. CI only runs them when this file is touched, which is why they went unnoticed. Searching for the model filters the list to it, so the cases no longer depend on how long the preset list grows. * revert(test): drop the dashboard scorer defaults parity test It parsed TypeScript from Python with a hand-rolled brace matcher and a numeric literal regex, which is not a mechanism this repo should carry: two review rounds went into fixing the parser rather than the feature. The UI copy of the defaults is display only, since an untouched knob is omitted from the payload, so drift shows a stale placeholder and cannot pin a router. * fix(ui): clamp the scorer inputs and drive the panel from one group spec min and max are inert attributes on a text input, so the fields accepted a weight of 999, a boundary of -50, and Infinity, and persisted them into the router config. Values are now clamped on commit and non-finite input is refused. The three sections were near copies of each other, so they now render from a single group spec, which also removes the triplicated warning logic. Moves the scorer constants and types into heuristic_scoring_knobs, the leaf module. Reading them back through ComplexityRouterConfig was a cycle, so the top-level DIMENSION_KEYS.map in the panel ran while the constant was still undefined and every test importing it failed to collect. * feat(ui): serve the scorer defaults from the proxy instead of mirroring them The dashboard kept its own copy of DEFAULT_TIER_BOUNDARIES, DEFAULT_TOKEN_THRESHOLDS and DEFAULT_DIMENSION_WEIGHTS to prefill the Advanced scoring controls. Two copies of one fact, and the earlier attempt to police the gap parsed TypeScript from a Python test, which was worse than the problem. GET /public/complexity_router/scorer_defaults now returns them, following the /public/providers/fields pattern: a typed response model, the dashboard fetching it through a react-query hook next to useProviderFields. The controls and the "How Classification Works" card both read that, so a recalibration of the defaults can no longer leave the form stating numbers the router stopped using. The dimension set now comes from the proxy too, so a dimension added backend-side renders without a dashboard change, under its raw key until it is given a label. Hydration keeps a stored dict exactly as stored rather than filling it from a local copy, since the backend already defaults any key omitted at scoring time. * fix(types): type the scorer defaults response as Mapping, not dict LIT001 gates mutable collections in annotations, and the three dict fields tripped it. Mapping is what the codebase already uses for a read-only map on a response model, and the endpoint hands the config constants over directly rather than copying them into a fresh dict, which would have traded the LIT001 hit for a LIT002 one. * test(ui): stub the scorer defaults request for the auto-router tree The Advanced scoring panel and the classification card read the shipped defaults over the network, so every render of that tree in a test paid for a request jsdom cannot serve. That was enough to push the slowest default-model-pin case past its 30s timeout on CI, where the suite runs 14 forks in parallel. One fixture in tests/mocks, pulled in by a single vi.mock line per test file, rather than the same stub pasted into each of the seven that render the tree. * fix(ui): tell a failed scorer-defaults load apart from a slow one The panel read only the query's data, so a permanent failure was indistinguishable from a request still in flight and it sat on "Loading the shipped defaults..." for good. It now branches on the query state: pending says loading, an error says so and offers a retry, and the values the router already overrides stay visible and editable either way. Two more places had the same flaw. The classification card silently dropped the tier ranges it used to always show, and now says they could not be loaded. The weight total was summed over whatever keys were present, so a failed load made it state a total built from the overrides alone; a total is only shown when the dimension set is known. --- .../public_endpoints/public_endpoints.py | 23 ++ .../public_endpoints/public_endpoints.py | 13 + .../autoRouter/useComplexityScorerDefaults.ts | 16 ++ .../add_model/AutoRouterRoutingTest.test.tsx | 4 + .../add_model/ClassificationMethodConfig.tsx | 84 +++++-- ...lassifierPromptEditor.integration.test.tsx | 4 + .../add_model/ComplexityRouterConfig.test.tsx | 4 + .../add_model/ComplexityRouterConfig.tsx | 28 +++ .../add_model/HeuristicScoringConfig.test.tsx | 201 ++++++++++++++++ .../add_model/HeuristicScoringConfig.tsx | 226 ++++++++++++++++++ .../add_model/add_auto_router_tab.test.tsx | 4 + .../add_model/add_auto_router_tab.tsx | 3 + .../build_complexity_router_config.test.ts | 26 ++ .../build_complexity_router_config.ts | 44 ++++ .../add_model/heuristic_scoring_knobs.test.ts | 65 +++++ .../add_model/heuristic_scoring_knobs.ts | 48 ++++ ...d_updated_complexity_router_config.test.ts | 23 ++ .../edit_auto_router_modal.test.tsx | 4 + .../edit_auto_router_modal.tsx | 16 ++ .../src/components/model_info_view.test.tsx | 4 + .../src/components/networking.tsx | 15 ++ .../src/lib/autorouter_presets.test.ts | 8 + ui/litellm-dashboard/src/lib/http/schema.d.ts | 61 +++++ .../tests/mocks/complexityScorerDefaults.ts | 33 +++ 24 files changed, 934 insertions(+), 23 deletions(-) create mode 100644 ui/litellm-dashboard/src/app/(dashboard)/hooks/autoRouter/useComplexityScorerDefaults.ts create mode 100644 ui/litellm-dashboard/src/components/add_model/HeuristicScoringConfig.test.tsx create mode 100644 ui/litellm-dashboard/src/components/add_model/HeuristicScoringConfig.tsx create mode 100644 ui/litellm-dashboard/src/components/add_model/heuristic_scoring_knobs.test.ts create mode 100644 ui/litellm-dashboard/src/components/add_model/heuristic_scoring_knobs.ts create mode 100644 ui/litellm-dashboard/tests/mocks/complexityScorerDefaults.ts diff --git a/litellm/proxy/public_endpoints/public_endpoints.py b/litellm/proxy/public_endpoints/public_endpoints.py index 47e30555a4f..4d58a974bb8 100644 --- a/litellm/proxy/public_endpoints/public_endpoints.py +++ b/litellm/proxy/public_endpoints/public_endpoints.py @@ -28,6 +28,7 @@ from litellm.types.proxy.management_endpoints.model_management_endpoints import ) from litellm.types.proxy.public_endpoints.public_endpoints import ( AgentCreateInfo, + ComplexityScorerDefaults, ProviderCreateInfo, PublicModelHubInfo, SupportedEndpointsResponse, @@ -398,6 +399,28 @@ async def get_provider_fields() -> list[ProviderCreateInfo]: return provider_create_fields +@router.get( + "/public/complexity_router/scorer_defaults", + tags=["public", "auto router"], + response_model=ComplexityScorerDefaults, +) +async def get_complexity_scorer_defaults() -> ComplexityScorerDefaults: + """ + Return the complexity router's shipped heuristic scorer defaults, for the dashboard to prefill with. + """ + from litellm.router_strategy.complexity_router.config import ( + DEFAULT_DIMENSION_WEIGHTS, + DEFAULT_TIER_BOUNDARIES, + DEFAULT_TOKEN_THRESHOLDS, + ) + + return ComplexityScorerDefaults( + tier_boundaries=DEFAULT_TIER_BOUNDARIES, + token_thresholds=DEFAULT_TOKEN_THRESHOLDS, + dimension_weights=DEFAULT_DIMENSION_WEIGHTS, + ) + + @router.get( "/public/litellm_model_cost_map", tags=["public", "model management"], diff --git a/litellm/types/proxy/public_endpoints/public_endpoints.py b/litellm/types/proxy/public_endpoints/public_endpoints.py index dbe34926f4b..f6ee054ceaa 100644 --- a/litellm/types/proxy/public_endpoints/public_endpoints.py +++ b/litellm/types/proxy/public_endpoints/public_endpoints.py @@ -1,3 +1,4 @@ +from collections.abc import Mapping from typing import Any, Literal from pydantic import BaseModel @@ -68,3 +69,15 @@ class SupportedEndpoint(BaseModel): class SupportedEndpointsResponse(BaseModel): endpoints: list[SupportedEndpoint] + + +class ComplexityScorerDefaults(BaseModel): + """The complexity router's shipped heuristic scorer defaults. + + The dashboard prefills its Advanced scoring controls from these rather than keeping its own copy, so + a recalibration of the defaults cannot leave the form reporting numbers the router no longer uses. + """ + + tier_boundaries: Mapping[str, float] + token_thresholds: Mapping[str, int] + dimension_weights: Mapping[str, float] diff --git a/ui/litellm-dashboard/src/app/(dashboard)/hooks/autoRouter/useComplexityScorerDefaults.ts b/ui/litellm-dashboard/src/app/(dashboard)/hooks/autoRouter/useComplexityScorerDefaults.ts new file mode 100644 index 00000000000..9502eb33b35 --- /dev/null +++ b/ui/litellm-dashboard/src/app/(dashboard)/hooks/autoRouter/useComplexityScorerDefaults.ts @@ -0,0 +1,16 @@ +import { ComplexityScorerDefaults, getComplexityScorerDefaults } from "@/components/networking";

MessageManager and NotificationManager become thin facades over lib/toast so the ~250 existing call sites keep working; the mutable antd instance setters, setMessageInstance/setNotificationInstance, and the antd App/message/ notification providers in AntdGlobalProvider are gone. Prunes the eslint suppression baseline accordingly. * test(ui): mock the MessageManager seam in the Fallbacks tests and drop toast doc comments AddFallbacks and FallbackSelectionForm asserted on a mocked antd message spy that MessageManager no longer calls; they now mock the facade the components import. Also removes the explanatory comments Greptile flagged in lib/toast.ts and both facades. * fix(ui): keep NotificationManager's antd config-object contract on the sonner facade success/info/warning/error accept the { message, description, duration } object form again (CreateMCPServer's admin-review notice uses it) and fromBackend keeps its extra.duration seconds argument, both mapped onto lib/toast. Prunes stale suppressions picked up by the rebase. * feat(ui): read the proxy error type and code out of JSON envelopes embedded in string errors Legacy networking helpers throw new Error(responseText) and callers prefix that text, so the envelope arrives as a substring. fromError now parses the first embedded JSON object for type/code and shows the unwrapped message in its place, so those toasts get a status title (Request Error, Not Found) and a readable description instead of raw JSON. --- ui/litellm-dashboard/eslint-suppressions.json | 68 +-- ui/litellm-dashboard/package-lock.json | 17 + ui/litellm-dashboard/package.json | 1 + ui/litellm-dashboard/src/app/layout.tsx | 2 + .../Fallbacks/AddFallbacks.test.tsx | 19 +- .../Fallbacks/FallbackSelectionForm.test.tsx | 17 +- .../molecules/message_manager.test.ts | 136 +++--- .../components/molecules/message_manager.tsx | 40 +- .../molecules/notifications_manager.test.tsx | 70 ---- .../molecules/notifications_manager.tsx | 391 ++---------------- .../src/components/ui/sonner.tsx | 34 ++ .../src/contexts/AntdGlobalProvider.tsx | 24 +- ui/litellm-dashboard/src/lib/toast.test.ts | 177 ++++++++ ui/litellm-dashboard/src/lib/toast.ts | 148 +++++++ 14 files changed, 493 insertions(+), 651 deletions(-) delete mode 100644 ui/litellm-dashboard/src/components/molecules/notifications_manager.test.tsx create mode 100644 ui/litellm-dashboard/src/components/ui/sonner.tsx create mode 100644 ui/litellm-dashboard/src/lib/toast.test.ts create mode 100644 ui/litellm-dashboard/src/lib/toast.ts diff --git a/ui/litellm-dashboard/eslint-suppressions.json b/ui/litellm-dashboard/eslint-suppressions.json index bd8b6457262..c3b2bb03f11 100644 --- a/ui/litellm-dashboard/eslint-suppressions.json +++ b/ui/litellm-dashboard/eslint-suppressions.json @@ -9,11 +9,6 @@ "count": 2 } }, -

An ambiguous post-send failure such as a read timeout after the write had already committed therefore stacked a second increment and inflated the billable unit totals served by the guardrail usage endpoints. Retry only DB_RETRY_SAFE_ERROR_TYPES (httpx.ConnectError), the same rule the spend writer and autorouter rollup use for increment upserts, and log any other failure once as terminal for that row while the rest of the batch still lands.

The submitted request bodies are unchanged. Budget create and edit previously relied on antd InputNumber precision={2}, which rounds the submitted value rather than only the display. That rounding is now an explicit shared helper so the wire payload stays identical, and the helper carries unit tests covering key presence, null passthrough, negatives and non-finite input. Characterization tests for both budget modals were written against the antd implementation first and pass unchanged against the migrated components, which is what pins the payload. They are named .integration.test.tsx per the dashboard test tiers, with the pure rounding logic unit tested separately. * fix(ui): keep collapsed Optional Settings values so reopening does not lose them react-hook-form shouldUnregister deletes a field's value when its section unmounts, so typing a budget, collapsing Optional Settings and reopening it submitted the seeded default instead of what was typed. antd reported only mounted fields in onFinish but preserved their values in its store, so the two behaviours have to be reproduced separately. Drop shouldUnregister, drive the section from controlled state, and blank the section's fields at submit while it is closed. Seed the edit form from the five form fields rather than the whole budget record, which shouldUnregister had been masking. --- .../_components/budgetPrecision.test.ts | 45 ++ .../budgets/_components/budgetPrecision.ts | 18 + .../budget_modal.integration.test.tsx | 139 ++++++ .../budgets/_components/budget_modal.tsx | 166 +++++-- .../edit_budget_modal.integration.test.tsx | 112 +++++ .../budgets/_components/edit_budget_modal.tsx | 169 +++++-- .../skills/_components/add_plugin_form.tsx | 420 +++++++++++------- 7 files changed, 806 insertions(+), 263 deletions(-) create mode 100644 ui/litellm-dashboard/src/app/(dashboard)/budgets/_components/budgetPrecision.test.ts create mode 100644 ui/litellm-dashboard/src/app/(dashboard)/budgets/_components/budgetPrecision.ts create mode 100644 ui/litellm-dashboard/src/app/(dashboard)/budgets/_components/budget_modal.integration.test.tsx create mode 100644 ui/litellm-dashboard/src/app/(dashboard)/budgets/_components/edit_budget_modal.integration.test.tsx diff --git a/ui/litellm-dashboard/src/app/(dashboard)/budgets/_components/budgetPrecision.test.ts b/ui/litellm-dashboard/src/app/(dashboard)/budgets/_components/budgetPrecision.test.ts new file mode 100644 index 00000000000..358ea2980a6 --- /dev/null +++ b/ui/litellm-dashboard/src/app/(dashboard)/budgets/_components/budgetPrecision.test.ts @@ -0,0 +1,45 @@ +import { describe, expect, it } from "vitest";
