RED -> GREEN: check_type_discipline flagged both vars LIT010 before -> LIT010 gone after (file total 551 -> 549, LIT002 unchanged at 953); test_calculate_web_search_requests_counts_unique_queries still passes. --- .../gemini/test_vertex_and_google_ai_studio_gemini.py | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) diff --git a/tests/test_litellm/llms/vertex_ai/gemini/test_vertex_and_google_ai_studio_gemini.py b/tests/test_litellm/llms/vertex_ai/gemini/test_vertex_and_google_ai_studio_gemini.py index d14fb6021ed..3a04424a581 100644 --- a/tests/test_litellm/llms/vertex_ai/gemini/test_vertex_and_google_ai_studio_gemini.py +++ b/tests/test_litellm/llms/vertex_ai/gemini/test_vertex_and_google_ai_studio_gemini.py @@ -2,7 +2,7 @@ import asyncio import json import re from copy import deepcopy -from typing import List, cast +from typing import Final, List, cast from unittest.mock import MagicMock, patch import pytest @@ -5562,10 +5562,12 @@ def test_calculate_web_search_requests_counts_unique_queries(): metadata items must collapse to the distinct-query count, and empty strings must be ignored, matching Google's documented Grounding-with-Search billing rule.

A statement holds one assignment at most, so the search now stops at the first operator that reads as one: everything after it is the expression being assigned, where an `=` only ever compares. Nine shapes were flagged this way, a cast, a `coalesce`, a `format`, a named-argument arrow and the rest, and all of them are valid PL/pgSQL that leaves the table untouched. `INTO` and `USING` no longer count as names an `EXECUTE` runs. Masking blanks a literal in place, so `EXECUTE '' INTO n` left `INTO` looking like the name being run, and an ordinary query reaching the same word collided with it. The docstring claiming that collision was impossible was wrong, and both words are now dropped instead. A loop is a fourth way a literal reaches a variable. `FOR stmt IN SELECT '' LOOP EXECUTE stmt` empties the table and the gate passed it, so the target of a `FOR` or a `FOREACH` is read as assigned too. Reading each statement once rather than once per operator also drops the cost of a statement with thousands of them from seconds to milliseconds. --- .../check_migrations_no_data_rewrites.py | 103 +++++++++----- .../test_check_migrations_no_data_rewrites.py | 134 ++++++++++++++++++ 2 files changed, 198 insertions(+), 39 deletions(-) diff --git a/tests/code_coverage_tests/check_migrations_no_data_rewrites.py b/tests/code_coverage_tests/check_migrations_no_data_rewrites.py index 9e6df46899b..dcb81593e3e 100644 --- a/tests/code_coverage_tests/check_migrations_no_data_rewrites.py +++ b/tests/code_coverage_tests/check_migrations_no_data_rewrites.py @@ -41,8 +41,9 @@ hide.

That set included whichever header carried the caller's LiteLLM virtual key: x-litellm-api-key, or Authorization when get_litellm_virtual_key read the key from there. The proxy's own secret was sent to a third-party provider. The credential-less branch now drops x-litellm-api-key and the Authorization value that equals the virtual key, keeping a genuine bring-your-own Google credential (an OAuth token in Authorization, or x-goog-api-key) so real BYO passthrough still works. When neither survives, the request fails with a clean 401 telling the operator no credential is configured, instead of forwarding the virtual key. Regression coverage in the mapped test path asserts the 401-and-never-forwarded behavior for both leak vectors and that a real Google credential still passes through with the virtual key stripped. --- .../llm_passthrough_endpoints.py | 50 ++++- .../test_llm_pass_through_endpoints.py | 188 +++++++++++++++--- 2 files changed, 198 insertions(+), 40 deletions(-) diff --git a/litellm/proxy/pass_through_endpoints/llm_passthrough_endpoints.py b/litellm/proxy/pass_through_endpoints/llm_passthrough_endpoints.py index 7ce41c1d5b6..0650735686f 100644 --- a/litellm/proxy/pass_through_endpoints/llm_passthrough_endpoints.py +++ b/litellm/proxy/pass_through_endpoints/llm_passthrough_endpoints.py @@ -9,7 +9,7 @@ Use litellm with Anthropic SDK, Vertex AI SDK, Cohere SDK, etc. import json import os import re -from collections.abc import Callable +from collections.abc import Callable, Mapping from types import MappingProxyType from typing import TYPE_CHECKING, Annotated, Any, Final, cast @@ -1726,6 +1726,42 @@ def _override_vertex_params_from_router_credentials( return vertex_project, vertex_location +_CREDENTIALLESS_VERTEX_MISSING_CREDENTIAL_DETAIL: Final = ( + "No Vertex AI credential is configured on this proxy and the request carried no upstream " + "Google credential.

the endpoint is now selected from the inputs present (promptVideo/videoUri, promptImage, or text only) - get_error_class raised instead of returning, turning a provider 4xx into a proxy 500 APIConnectionError; it now returns a RunwayMLError - VideoObject.progress was typed int while Runway sends a 0..1 float, 500'ing status polls while RUNNING; it is now scaled to a 0..100 percent - custom per-deployment pricing stored under litellm_metadata was ignored for video; the deployment model_info lookup now checks both metadata keys - stale cost-map entries (gen3a_turbo, gen4_aleph) were removed and current models added, with output_cost_per_second_480p/_4k tier keys plumbed through the model-info and router types - video cost now falls back to Runway's estimatedCost from the create response when no custom pricing is configured, and custom pricing always wins over it Fixes #36483 --- litellm/cost_calculator.py | 18 ++- .../exception_mapping_utils.py | 1 + litellm/llms/openai/cost_calculation.py | 9 +- .../llms/runwayml/videos/transformation.py | 115 +++++++++---- ...odel_prices_and_context_window_backup.json | 151 +++++++++++++++++- litellm/types/router.py | 4 +- litellm/types/utils.py | 4 + litellm/utils.py | 2 + model_prices_and_context_window.json | 151 +++++++++++++++++- .../test_exception_mapping_utils.py | 3 + .../test_runway_video_transformation.py | 140 +++++++++++++++- tests/test_litellm/test_utils.py | 5 + tests/test_litellm/test_video_generation.py | 111 +++++++++++++ ui/litellm-dashboard/src/lib/http/schema.d.ts | 8 + 14 files changed, 667 insertions(+), 55 deletions(-) diff --git a/litellm/cost_calculator.py b/litellm/cost_calculator.py index 8f7cd09d364..58d29d99e3e 100644 --- a/litellm/cost_calculator.py +++ b/litellm/cost_calculator.py @@ -150,6 +150,7 @@ _VIDEO_CALL_TYPES: Final = frozenset( } ) + _SPEECH_CALL_TYPES: Final = frozenset( { CallTypes.speech.value, @@ -1372,23 +1373,36 @@ def completion_cost( if custom_pricing and litellm_logging_obj is not None: _litellm_params = getattr(litellm_logging_obj, "litellm_params", None) if _litellm_params is not None: - _metadata = _litellm_params.get("metadata", {}) or {} - _video_model_info = _metadata.get("model_info", None) + _video_model_info = next( + ( + model_info + for _metadata_key in ("metadata", "litellm_metadata") + if (model_info := (_litellm_params.get(_metadata_key) or {}).get("model_info")) + is not None + ), + None, + ) usage_obj = getattr(completion_response, "usage", None) duration_seconds: float | None = None video_resolution: str | None = None + provider_reported_cost: float | None = None if completion_response is not None and usage_obj: # Handle both dict and Pydantic Usage object if isinstance(usage_obj, dict): duration_seconds = usage_obj.get("duration_seconds", None) _vr = usage_obj.get("video_resolution", None) + provider_reported_cost = usage_obj.get("provider_reported_cost_usd", None) else: duration_seconds = getattr(usage_obj, "duration_seconds", None) _vr = getattr(usage_obj, "video_resolution", None) + provider_reported_cost = getattr(usage_obj, "provider_reported_cost_usd", None) if _vr is not None: video_resolution = str(_vr).strip().lower() + if _video_model_info is None and provider_reported_cost is not None: + return float(provider_reported_cost) + if duration_seconds is not None: # Calculate cost based on video duration using video-specific cost calculation from litellm.llms.openai.cost_calculation import ( diff --git a/litellm/litellm_core_utils/exception_mapping_utils.py b/litellm/litellm_core_utils/exception_mapping_utils.py index 4a25eb218c0..4ee726b67de 100644 --- a/litellm/litellm_core_utils/exception_mapping_utils.py +++ b/litellm/litellm_core_utils/exception_mapping_utils.py @@ -2301,6 +2301,7 @@ def exception_type( or custom_llm_provider == "custom_openai" or custom_llm_provider in litellm.openai_compatible_providers or custom_llm_provider == "mistral" + or custom_llm_provider == "runwayml" ): _map_openai_exception( model=model, diff --git a/litellm/llms/openai/cost_calculation.py b/litellm/llms/openai/cost_calculation.py index 0352d246c09..115b2e27983 100644 --- a/litellm/llms/openai/cost_calculation.py +++ b/litellm/llms/openai/cost_calculation.py @@ -134,14 +134,7 @@ def cost_per_second(model: str, custom_llm_provider: str | None, duration: float def _video_resolution_to_cost_field_suffix(resolution: str) -> str | None: - """ - Map usage resolution to a safe suffix for ``output_cost_per_second_`` keys. - - Note: Currently only ``output_cost_per_second_1080p`` is explicitly declared in - ModelInfo (types/utils.py).

A union `type` array, or an enum value whose JSON type differs from a scalar `type`, is rejected with "Invalid schema: Enum value 'low' does not match declared type '['string','null']'" filter_anthropic_output_schema had no enum/type reconciliation, so both keys reached Anthropic untouched. Drop the conflicting `type` -- `enum` is the tighter constraint, and an enum with no `type` is accepted The drop is conditional: `type` is only removed when it is a union array, or when some enum value does not match the scalar type. A matching enum plus scalar `type` is left exactly as-is, so existing behaviour is unchanged Pydantic emits the failing shape for Optional[SomeEnum], so this affects any caller with a nullable enum field on the native output_format path. vertex_ai is unaffected because it is forced onto the permissive tool-use path Fixes #37881 * refactor(anthropic): make enum/type reconciliation immutable and precisely typed Address review: the predicate registry was a mutable `dict[str, Any]`, and the reconciliation removed `type` by mutating the built result with `pop` - registry is now `Final[Mapping[str, Callable[[Any], bool]]]` wrapped in `MappingProxyType`, so predicate signatures are statically checked and the table cannot be mutated - the conflict decision moves into a pure helper evaluated once against the input schema, and the conflicting `type` key is skipped at build time in the existing loop instead of being popped afterwards, so nothing is mutated Behaviour is unchanged;

Pure cover The seam is `provider_edge.py`: `start_provider_edge` boots an in-process HTTP server (one shared instance per pytest process, `e2e_config.provider_edge_base` is the accessor) that mounts each supported provider under a path prefix (`EDGE_MOUNTS`: `/openai` -> `https://api.openai.com`, `/anthropic` -> `https://api.anthropic.com`). A test participates by registering its deployment with `api_base=provider_edge_base("openai")` plus the provider's path suffix; `quota_management/spend_tracking/test_provider_edge_spend_e2e.py` is the reference. In live mode the accessor returns None and the deployment defaults to the real provider, so an edge-wired test runs in all three modes unchanged. Non-wired tests hit their providers live in every mode.

Request headers are never stored (provider credentials never touch disk), non-JSON request bodies store a canonicalized sha256 digest instead of the bytes, `multipart/form-data` bodies store their ordinary fields plus a JSON list of the uploaded parts' `[field, filename, content-type]` triples and a digest of their content, so the per-request random boundary and the envelope never reach the key, and responses store status, filtered headers, and the verbatim body base64-encoded, which is part of why bundles are gitignored. Responses come in two shapes told apart by a `kind` tag: an ordinary one holding a single base64 body, and, for a response the provider streamed (`content-type: text/event-stream`), one holding its transfer chunks in order plus why the stream ended early if it did, so replay reproduces the split points the provider chose instead of one coalesced body. `fixture_bundle.py` owns the format, and `BUNDLE_FORMAT_VERSION` is checked on load, so a bundle recorded under older rules is refused by name rather than partially read. Record serves the proxy the same filtered stored response replay will serve later, chunk for chunk on a stream, so the two modes are byte-identical from the proxy's side of the socket Multipart identity is the fiddly corner, and the rules exist because each one had a collision behind it. A part counts as an upload when it carries a filename or declares its own content type, and everything else is an ordinary field. Field names get a `name[n]` suffix on repeats, with a literal `[` doubled first, so a form that repeats `purpose` never keys the same as one that literally sends `purpose[1]`.
