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. --- ui/litellm-dashboard/src/app/globals.css | 2 + .../components/molecules/logo/Logo.test.tsx | 34 +++++++++++ .../src/components/molecules/logo/Logo.tsx | 11 +++- .../src/lib/logoTreatments.test.ts | 56 +++++++++++++++++++ .../src/lib/logoTreatments.ts | 56 +++++++++++++++++++ 5 files changed, 158 insertions(+), 1 deletion(-) create mode 100644 ui/litellm-dashboard/src/lib/logoTreatments.test.ts create mode 100644 ui/litellm-dashboard/src/lib/logoTreatments.ts diff --git a/ui/litellm-dashboard/src/app/globals.css b/ui/litellm-dashboard/src/app/globals.css index f389fa5df3d..87959ca0139 100644 --- a/ui/litellm-dashboard/src/app/globals.css +++ b/ui/litellm-dashboard/src/app/globals.css @@ -140,6 +140,7 @@ --sidebar-border: oklch(0.928 0.006 264.531); --sidebar-ring: oklch(0.707 0.022 261.325); --neutral-border: #dcddeb; + --logo-surface: oklch(1 0 0); } .dark { @@ -227,6 +228,7 @@ --color-sidebar-accent-foreground: var(--sidebar-accent-foreground); --color-sidebar-border: var(--sidebar-border); --color-sidebar-ring: var(--sidebar-ring); + --color-logo-surface: var(--logo-surface); } @layer base { diff --git a/ui/litellm-dashboard/src/components/molecules/logo/Logo.test.tsx b/ui/litellm-dashboard/src/components/molecules/logo/Logo.test.tsx index 5e4da208f4e..62ce8e9ee12 100644 --- a/ui/litellm-dashboard/src/components/molecules/logo/Logo.test.tsx +++ b/ui/litellm-dashboard/src/components/molecules/logo/Logo.test.tsx @@ -52,6 +52,40 @@ describe("Logo", () => { warnSpy.mockRestore(); }); + it("leaves the caller's class list untouched for an asset that reads on dark", () => { + render(); + expect(screen.getByRole("img", { name: "Slack logo" })).toHaveClass("w-5 h-5 shrink-0", { exact: true }); + }); + + it("passes an untreated logo's classes through verbatim rather than normalizing them", () => { + render(); + expect(screen.getByRole("img", { name: "Slack logo" })).toHaveClass("w-4 w-5 h-5", { exact: true }); + }); + + it("forces a monochrome mark to white on dark without disturbing the caller's classes", () => { + render(); + const img = screen.getByRole("img", { name: "GitHub logo" }); + expect(img).toHaveClass("w-5", "h-5", "dark:[filter:brightness(0)_invert(1)]"); + expect(img).not.toHaveClass("dark:bg-logo-surface"); + }); + + it("plates a multicolor dark mark rather than inverting it", () => { + render(); + const img = screen.getByRole("img", { name: "Fireworks logo" }); + expect(img).toHaveClass("dark:bg-logo-surface", "dark:object-contain", "dark:p-0.5"); + expect(img).not.toHaveClass("dark:[filter:brightness(0)_invert(1)]"); + }); + + it("does not treat an external logo URL that collides with a bundled filename", () => { + render(); + expect(screen.getByRole("img", { name: "Ext logo" })).toHaveClass("w-5 h-5", { exact: true }); + }); + + it("applies the treatment to a provider logo resolved through the bundler", () => { + render(); + expect(screen.getByRole("img", { name: "openrouter logo" })).toHaveClass("dark:[filter:brightness(0)_invert(1)]"); + }); + it("retries with a new src after a previous src errored", () => { const warnSpy = vi.spyOn(console, "warn").mockImplementation(() => {}); const { rerender } = render(); diff --git a/ui/litellm-dashboard/src/components/molecules/logo/Logo.tsx b/ui/litellm-dashboard/src/components/molecules/logo/Logo.tsx index d388e3dc07d..66c10f1e222 100644 --- a/ui/litellm-dashboard/src/components/molecules/logo/Logo.tsx +++ b/ui/litellm-dashboard/src/components/molecules/logo/Logo.tsx @@ -1,12 +1,19 @@ import React, { useState } from "react"; import { getProviderLogoAndName } from "@/components/provider_info_helpers"; import { resolveLogoSrc } from "@/lib/assetPaths"; +import { cn } from "@/lib/cva.config"; +import { logoTreatmentFor, type LogoTreatment } from "@/lib/logoTreatments"; type LogoProps = { className?: string } & ( | { provider: string; src?: never; label?: string } | { provider?: never; src: string | null | undefined; label: string } ); +const DARK_TREATMENT_CLASS: Readonly> = { + invert: "dark:[filter:brightness(0)_invert(1)]", + plate: "dark:bg-logo-surface dark:object-contain dark:p-0.5", +}; + export const Logo: React.FC = ({ provider, src, label, className = "w-4 h-4" }) => { const [erroredSrc, setErroredSrc] = useState(null); const resolvedSrc = provider !== undefined ? getProviderLogoAndName(provider).logo : resolveLogoSrc(src) ??

Every model that supports "none" without defaulting to it therefore had temperature forwarded and rejected upstream, and because the carve-out returned before the drop_params branch, drop_params: true could not save it. Declare the fact instead. A new cost-map key, default_reasoning_effort, states the effort the provider applies when the request omits one, and one shared predicate resolves the effective effort from it: an explicit reasoning_effort wins, otherwise the declared default, otherwise the catalogue decides. That last step matters because the cost map is fetched from the published branch at import time, so it can be OLDER than the code reading it. On such a map every model looks undeclared, and reading that as "reasoning is active" would strip temperature from the 39 gpt-5.1/5.2/5.4 entries that accept it, a regression caused by data lag rather than by anything about the model. So an absent declaration is only meaningful once the catalogue carries the key at all; a map that predates the feature keeps the answer litellm gave before it existed, and the conservative answer applies from the moment the data lands. The top_p/logprobs/top_logprobs gate carried the same assumption spelled differently and now shares the predicate, as does the Responses API, which reimplemented the rule and is what the default /v1/messages bridge routes openai models through. Azure normalises its routing names in one resolver that every capability lookup goes through, which replaces its bespoke per-lookup rewrite.

litellm/llms/litellm_proxy/skills/code_execution.py: the OpenAI and Anthropic tool schemas were unpinned (the Anthropic one was not reached by any test at all) and the handler's default fallbacks were unchecked - litellm/containers/endpoint_factory.py: the endpoints.json contract, the generated sync/async function set and the response-type mapping were unpinned - litellm/llms/openai_like/dynamic_config.py: the generated Responses API config class had no coverage of auth header, URL resolution or the store override The openai_like tests clear _responses_config_cache around each test. Without that, the module-level cache hands back a class built before the mutation and the tests pass against mutated code. Verified by re-running mutmut per scope: llms/litellm_proxy 45.2% -> 62.8% (70 mutants newly killed) containers 36.8% -> 84.3% (45 mutants newly killed) llms/openai_like 55.7% -> 66.9% (34 mutants

identity instead of mutating it The previous check proved _load_endpoints_config returns a fresh object by clearing the first result and reloading. That mutates shared state and only works while the loader happens not to cache, so a future cache would corrupt every later test rather than fail this one. Compare the two loads by identity and equality instead. Verified red-before-green: adding a module-level cache to the loader fails this test, removing it passes. --- tests/test_litellm/containers/test_endpoint_factory.py | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/tests/test_litellm/containers/test_endpoint_factory.py b/tests/test_litellm/containers/test_endpoint_factory.py index 46564bb1810..8de0d039afc 100644 --- a/tests/test_litellm/containers/test_endpoint_factory.py +++ b/tests/test_litellm/containers/test_endpoint_factory.py @@ -47,8 +47,10 @@ class TestEndpointsConfig: def test_config_is_reread_rather_than_shared_between_callers(self): first = _load_endpoints_config() - first["endpoints"].clear() - assert len(_load_endpoints_config()["endpoints"]) == len(_SYNC_NAMES) + second = _load_endpoints_config() + assert first is not second + assert first["endpoints"] is not second["endpoints"] + assert first == second class TestResponseTypeMapping: From c5cdd2e8e12c47f77d7ff8d042c029d3a9f00710 Mon Sep 17 00:00:00 2001 From: yucheng-berri Date: Fri, 28 Aug 2026 10:54:53 -0700 Subject: [PATCH 12/42] fix(logging): preserve null end user in callbacks (#38642) --- litellm/litellm_core_utils/litellm_logging.py | 2 +- .../test_litellm_logging.py | 35 +++++++++++++++++++ 2 files changed, 36 insertions(+), 1 deletion(-) diff --git a/litellm/litellm_core_utils/litellm_logging.py b/litellm/litellm_core_utils/litellm_logging.py index 157d436e482..a8672b5c112 100644 --- a/litellm/litellm_core_utils/litellm_logging.py +++ b/litellm/litellm_core_utils/litellm_logging.py @@ -6058,7 +6058,7 @@ def get_standard_logging_object_payload( prompt_tokens=usage_dict.get("prompt_tokens", 0), completion_tokens=usage_dict.get("completion_tokens", 0), request_tags=request_tags, - end_user=end_user_id or "", + end_user=end_user_id, api_base=StandardLoggingPayloadSetup.strip_trailing_slash(litellm_params.get("api_base", "")) or "", model_group=_model_group, model_id=_model_id, diff --git a/tests/test_litellm/litellm_core_utils/test_litellm_logging.py b/tests/test_litellm/litellm_core_utils/test_litellm_logging.py index af9f626dd17..1193160c831 100644 --- a/tests/test_litellm/litellm_core_utils/test_litellm_logging.py +++ b/tests/test_litellm/litellm_core_utils/test_litellm_logging.py @@ -3727,6 +3727,41 @@ def test_get_standard_logging_object_payload_includes_litellm_call_id(logging_ob assert payload["litellm_call_id"] == call_id +def test_get_standard_logging_object_payload_preserves_absent_end_user_as_none(logging_obj): + from datetime import datetime + from typing import Final + + from litellm.litellm_core_utils.litellm_logging import get_standard_logging_object_payload + from litellm.types.utils import StandardLoggingPayload + + now: Final = datetime.now() + payload: Final[StandardLoggingPayload | None] = get_standard_logging_object_payload( + kwargs={ + "model": "gpt-4o", + "messages": [], + "litellm_params": { + "metadata": { + "user_api_key_alias": "test-key-alias", + "user_api_key_user_id": "test-key-user", + "user_api_key_end_user_id": None, + }, + "proxy_server_request": {"body": {}}, + }, + }, + init_response_obj={}, + start_time=now, + end_time=now, + logging_obj=logging_obj, + status="success", + ) + + assert payload is not None + assert payload["metadata"]["user_api_key_alias"] == "test-key-alias" + assert payload["metadata"]["user_api_key_user_id"] == "test-key-user" + assert payload["metadata"]["user_api_key_end_user_id"] is None + assert payload["end_user"] is None + + # ── Azure Model Router selected-model attribution ──────────────────────────── From 2ef77f30e3e5973a80d0ff877df663ce3aab6b8d Mon Sep 17 00:00:00 2001 From: yucheng-berri Date: Fri, 28 Aug 2026 12:06:57 -0700 Subject: [PATCH 13/42] fix: enforce MCP toolsets attached to a team, org, or internal user (#38488) * fix: enforce MCP toolsets attached to a team, org, or internal user object_permission.mcp_toolsets was resolved into servers and tools only at the key level; every other principal read mcp_tool_permissions and silently ignored its toolsets. A team/org/user toolset alongside a server grant was inert (all tools callable), a toolset alone granted nothing, and an inert team toolset let the org server list substitute for the empty team result, handing the caller every org server. Resolve toolsets at each level that resolves mcp_tool_permissions, union their servers into that level's granted server set, and count a declared key/team toolset toward has_lower_level_mcp_restrictions so the org list can only cap, never substitute, even when the toolset resolves empty. Resolves LIT-5749 * fix: deny when a team's declared MCP toolset cannot be resolved The team server resolver swallowed UnloadableEntitlementError into an empty list, so a dangling team toolset dropped the team ceiling instead of denying, unlike the org and user paths. Re-raise it so the top-level resolver denies. Also anchor the test-quality suppression comments on the patch opener lines the gate reads, with per-seam reasons. --- .../mcp_server/auth/user_api_key_auth_mcp.py | 152 +++++- .../auth/test_user_api_key_auth_mcp.py | 463 +++++++++++++++++- 2 files changed, 596 insertions(+), 19 deletions(-) diff --git a/litellm/proxy/_experimental/mcp_server/auth/user_api_key_auth_mcp.py b/litellm/proxy/_experimental/mcp_server/auth/user_api_key_auth_mcp.py index bd8dfea3621..d5461f01ed8 100644 --- a/litellm/proxy/_experimental/mcp_server/auth/user_api_key_auth_mcp.py +++ b/litellm/proxy/_experimental/mcp_server/auth/user_api_key_auth_mcp.py @@ -1,5 +1,5 @@ import re -from collections.abc import Sequence +from collections.abc import Mapping, Sequence from dataclasses import dataclass from datetime import datetime, timezone from types import MappingProxyType @@ -67,6 +67,9 @@ if TYPE_CHECKING: from litellm.proxy.utils import PrismaClient +_EMPTY_TOOLSET_GRANTS: Final[Mapping[str, Sequence[str]]] = MappingProxyType({}) + + def _as_list(values: Sequence[str] | None) -> list[str] | None: # mutable-ok: resolver returns a list """Widen a read-only allowlist back to the mutable list the resolver's own contract returns, preserving the ``None`` that means "no restriction".""" @@ -1497,7 +1500,11 @@ class MCPRequestHandler: team_set: Final = set(allowed_mcp_servers_for_team) grants_set: Final = set(key_access_group_grants) - has_lower_level_mcp_restrictions = bool(key_set or team_set or grants_set) + # A DECLARED toolset restricts even when it resolves to no servers: the org + # ceiling below may only cap it, never substitute the org's full server list. + has_lower_level_mcp_restrictions = bool(key_set or team_set or grants_set) or ( + await MCPRequestHandler._key_or_team_declares_toolsets(user_api_key_auth) + ) # 1.

That recompute ran after the body's model field had already been restamped to the client-facing alias, so the cost calculator priced the alias (for example together_ai/muse-glimmer-30b) instead of the deployment model that spend logging uses. On Together AI that alias is unregistered and falls into the parameter-size bucket, so the header overbilled cold requests by about 2.3x and priced cache reads at zero on warm ones while recorded spend stayed correct. Move the restamp after every cost read of the response so the header and the spend logs price the same model, and add a regression test that pins the header to the provider-reported model while the body still returns the alias. --- litellm/proxy/common_request_processing.py | 20 ++++---- .../proxy/test_common_request_processing.py | 50 ++++++++++++++++++- 2 files changed, 58 insertions(+), 12 deletions(-) diff --git a/litellm/proxy/common_request_processing.py b/litellm/proxy/common_request_processing.py index f555966b76b..cbd50da9c3e 100644 --- a/litellm/proxy/common_request_processing.py +++ b/litellm/proxy/common_request_processing.py @@ -2551,16 +2551,6 @@ class ProxyBaseLLMRequestProcessing: except Exception as e: verbose_proxy_logger.exception("Error in orphaned streaming async logging: %s", e) - # Always return the client-requested model name (not provider-prefixed internal identifiers) - # for OpenAI-compatible responses. - if requested_model_from_client: - _override_openai_response_model( - response_obj=response, - requested_model=requested_model_from_client, - log_context=f"litellm_call_id={logging_obj.litellm_call_id}", - return_raw_model_name=_should_return_raw_model_name(self.data), - ) - hidden_params = get_hidden_params_dict(response) # get any updated response headers additional_headers = hidden_params.get("additional_headers", {}) or {} @@ -2586,6 +2576,16 @@ class ProxyBaseLLMRequestProcessing: else llm_cost_for_headers ) + # Always return the client-requested model name (not provider-prefixed internal identifiers) + # for OpenAI-compatible responses. + if requested_model_from_client: + _override_openai_response_model( + response_obj=response, + requested_model=requested_model_from_client, + log_context=f"litellm_call_id={logging_obj.litellm_call_id}", + return_raw_model_name=_should_return_raw_model_name(self.data), + ) + fastapi_response.headers.update( ProxyBaseLLMRequestProcessing.get_custom_headers( user_api_key_dict=user_api_key_dict, diff --git a/tests/test_litellm/proxy/test_common_request_processing.py b/tests/test_litellm/proxy/test_common_request_processing.py index 64318778bc2..71d4666416d 100644 --- a/tests/test_litellm/proxy/test_common_request_processing.py +++ b/tests/test_litellm/proxy/test_common_request_processing.py @@ -4710,7 +4710,9 @@ class TestResponseCostHeaderForTypedDictResponses: logging_obj._on_deferred_stream_complete = None return logging_obj - async def _drive_non_streaming(self, *, monkeypatch, response, logging_obj, route_type, return_result=False): + async def _drive_non_streaming( + self, *, monkeypatch, response, logging_obj, route_type, return_result=False, client_model=None + ): import litellm.proxy.common_request_processing as crp from litellm.proxy._types import UserAPIKeyAuth as RealUserAPIKeyAuth @@ -4732,7 +4734,9 @@ class TestResponseCostHeaderForTypedDictResponses: proxy_logging_obj.post_call_success_hook = fake_post_call_success_hook fastapi_response = Response() - processing_obj = ProxyBaseLLMRequestProcessing(data={"litellm_logging_obj": logging_obj}) + processing_obj = ProxyBaseLLMRequestProcessing( + data={"litellm_logging_obj": logging_obj, **({"model": client_model} if client_model else {})} + ) with patch.object( ProxyBaseLLMRequestProcessing, @@ -4783,6 +4787,48 @@ class TestResponseCostHeaderForTypedDictResponses: assert fastapi_response.headers["x-litellm-response-cost"] == "0.00123" recompute.assert_not_called() + @pytest.mark.asyncio + async def test_messages_cost_recompute_prices_provider_model_not_client_alias(self, monkeypatch): + """ + Regression for LIT-6339 / GH #38578.

Date: Fri, 28 Aug 2026 12:36:52 -0700 Subject: [PATCH 21/42] feat(auto_router): write and preview the classifier prompt an edited tier set sends (#38605) * 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 --- litellm/proxy/_types.py | 2 + .../model_management_endpoints.py | 45 +++++- .../complexity_router/__init__.py | 6 + .../complexity_router/complexity_router.py | 34 +++-- .../complexity_router/config.py | 25 ++- .../test_model_management_endpoints.py | 105 +++++++++++++ .../add_model/ClassificationMethodConfig.tsx | 18 ++- .../add_model/ComplexityRouterConfig.test.tsx | 47 +++++- .../add_model/ComplexityRouterConfig.tsx | 14 +- .../add_model/CustomTierPromptEditor.test.tsx | 129 ++++++++++++++++ .../add_model/CustomTierPromptEditor.tsx | 142 ++++++++++++++++++ .../add_model/add_auto_router_tab.test.tsx | 19 +++ .../add_model/add_auto_router_tab.tsx | 5 + .../build_complexity_router_config.test.ts | 20 +++ .../build_complexity_router_config.ts | 9 +- .../src/components/add_model/tier_rows.ts | 4 - ...d_updated_complexity_router_config.test.ts | 27 +++- .../edit_auto_router_modal.tsx | 15 +- .../src/components/networking.tsx | 66 +++++--- ui/litellm-dashboard/src/lib/http/schema.d.ts | 55 ++++++- 20 files changed, 726 insertions(+), 61 deletions(-) create mode 100644 ui/litellm-dashboard/src/components/add_model/CustomTierPromptEditor.test.tsx create mode 100644 ui/litellm-dashboard/src/components/add_model/CustomTierPromptEditor.tsx diff --git a/litellm/proxy/_types.py b/litellm/proxy/_types.py index 516fb620db6..f40b0632398 100644 --- a/litellm/proxy/_types.py +++ b/litellm/proxy/_types.py @@ -940,6 +940,8 @@ class LiteLLMRoutes(enum.Enum): # Model cost map maintenance views (read-only status / source).
