Widen the tool's input schema with optional objective and search_queries fields (query stays required), and forward the richer shape from the interception handler only to providers whose search config reports supports_rich_search_input().

Vertex splits prompt tokens by modality, so a session sending camera frames arrives with image_tokens set. Those were folded into text_tokens and lost their attribution. The amount happens not to move today, because the calculator falls back to input_cost_per_token when no per-modality rate is set, but the tokens have to survive before any such rate can ever apply. InputTokensDetails now declares image_tokens and video_tokens instead of leaning on pydantic extras, the repeated per-field copying is a loop over the modality names so adding a modality no longer adds a branch, and the read-back in ResponseAPILoggingUtils picks up video_tokens, which PromptTokensDetailsWrapper already declared. The output half of the original change is dropped: 449c091391 landed the same OutputTokensDetails.audio_tokens fix upstream, with its own coverage in test_gemini_realtime_transformation.py, and it always sets output_tokens_details rather than only when non-empty. That structure is kept as upstream wrote it. --- .../transformation.py | 2 ++ litellm/responses/utils.py | 1 + litellm/types/llms/openai.py | 2 ++ .../test_litellm_completion_responses.py | 33 +++++++++++++++++++ 4 files changed, 38 insertions(+) diff --git a/litellm/responses/litellm_completion_transformation/transformation.py b/litellm/responses/litellm_completion_transformation/transformation.py index 01fb6cb483d..ffd7ce491b1 100644 --- a/litellm/responses/litellm_completion_transformation/transformation.py +++ b/litellm/responses/litellm_completion_transformation/transformation.py @@ -2851,6 +2851,8 @@ class LiteLLMCompletionResponsesConfig: cached_tokens=prompt_details.cached_tokens if prompt_details.cached_tokens is not None else 0, text_tokens=prompt_details.text_tokens, audio_tokens=prompt_details.audio_tokens, + image_tokens=prompt_details.image_tokens, + video_tokens=prompt_details.video_tokens, cached_tokens_details=( cached_tokens_details if isinstance(cached_tokens_details, CachedTokensDetails) else None ), diff --git a/litellm/responses/utils.py b/litellm/responses/utils.py index 41a3ded7022..f50c17aff85 100644 --- a/litellm/responses/utils.py +++ b/litellm/responses/utils.py @@ -1182,6 +1182,7 @@ class ResponseAPILoggingUtils: cached_tokens_details=getattr( response_api_usage.input_tokens_details, "cached_tokens_details", None ), + video_tokens=getattr(response_api_usage.input_tokens_details, "video_tokens", None), cache_write_tokens=getattr(response_api_usage.input_tokens_details, "cache_write_tokens", None), web_search_requests=getattr(response_api_usage.input_tokens_details, "web_search_requests", None), google_maps_grounding_requests=getattr( diff --git a/litellm/types/llms/openai.py b/litellm/types/llms/openai.py index e3eac9b9205..98548705979 100644 --- a/litellm/types/llms/openai.py +++ b/litellm/types/llms/openai.py @@ -1291,7 +1291,9 @@ class InputTokensDetails(BaseLiteLLMOpenAIResponseObject): audio_tokens: int | None = None cached_tokens: int = 0 cached_tokens_details: CachedTokensDetails | None = None + image_tokens: int | None = None text_tokens: int | None = None + video_tokens: int | None = None model_config = {"extra": "allow"} diff --git a/tests/test_litellm/responses/litellm_completion_transformation/test_litellm_completion_responses.py b/tests/test_litellm/responses/litellm_completion_transformation/test_litellm_completion_responses.py index 0ed101952be..2f9f7adfcf1 100644 --- a/tests/test_litellm/responses/litellm_completion_transformation/test_litellm_completion_responses.py +++ b/tests/test_litellm/responses/litellm_completion_transformation/test_litellm_completion_responses.py @@ -2885,6 +2885,39 @@ class TestUsageTransformation: assert getattr(response_usage.input_tokens_details, "cache_write_tokens", None) == 800 assert response_usage.input_tokens_details.model_dump()["cache_write_tokens"] == 800 + def test_transform_usage_preserves_input_modality_tokens(self): + """Regression: the bridge dropped image and video input tokens. + + Vertex reports prompt tokens split by modality, so a Live session that sends + camera frames arrives with image_tokens set.

Dispatch any CustomLogger that overrides async_moderation_hook and hand the proxy router to every registered prompt injection detector at startup so that call can route Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> --- .../proxy/hooks/prompt_injection_detection.py | 2 + litellm/proxy/proxy_server.py | 11 ++- litellm/proxy/utils.py | 36 ++++++-- .../hooks/test_prompt_injection_detection.py | 82 ++++++++++++++++++- .../test_proxy_logging_hook_detection.py | 69 ++++++++++++++++ tests/test_litellm/proxy/test_proxy_server.py | 31 +++++++ 6 files changed, 219 insertions(+), 12 deletions(-) diff --git a/litellm/proxy/hooks/prompt_injection_detection.py b/litellm/proxy/hooks/prompt_injection_detection.py index 4eb81a58614..3f3bcc89b17 100644 --- a/litellm/proxy/hooks/prompt_injection_detection.py +++ b/litellm/proxy/hooks/prompt_injection_detection.py @@ -221,6 +221,8 @@ class _OPTIONAL_PromptInjectionDetection(CustomLogger): return None formatted_prompt: Final = get_formatted_prompt(data=data, call_type=call_type) + if not formatted_prompt: + return None is_prompt_attack = False prompt_injection_system_prompt: Final = getattr( diff --git a/litellm/proxy/proxy_server.py b/litellm/proxy/proxy_server.py index d7d8413d2ce..3af9aeccd69 100644 --- a/litellm/proxy/proxy_server.py +++ b/litellm/proxy/proxy_server.py @@ -1324,8 +1324,7 @@ async def proxy_startup_event(app: FastAPI) -> AsyncGenerator[None, None]: user_api_key_cache=user_api_key_cache, ) - if prompt_injection_detection_obj is not None: # [TODO] - REFACTOR THIS - prompt_injection_detection_obj.update_environment(router=llm_router) + ProxyStartupEvent._attach_router_to_prompt_injection_detectors(llm_router=llm_router) verbose_proxy_logger.debug("prisma_client: %s", prisma_client) if prisma_client is not None and litellm.max_budget > 0: @@ -9356,6 +9355,14 @@ def giveup(e): class ProxyStartupEvent: + @staticmethod + def _attach_router_to_prompt_injection_detectors(llm_router: Router | None) -> None: + for callback in litellm.logging_callback_manager.get_custom_loggers_for_type( + _OPTIONAL_PromptInjectionDetection + ): + if isinstance(callback, _OPTIONAL_PromptInjectionDetection): + callback.update_environment(router=llm_router) + @staticmethod async def refresh_model_info() -> None: if llm_router is not None: diff --git a/litellm/proxy/utils.py b/litellm/proxy/utils.py index 950ac5e9906..768e1d9a27c 100644 --- a/litellm/proxy/utils.py +++ b/litellm/proxy/utils.py @@ -17,6 +17,7 @@ from dataclasses import dataclass, field from datetime import date, datetime, timedelta, timezone from email.mime.multipart import MIMEMultipart from email.mime.text import MIMEText +from itertools import takewhile from types import MappingProxyType from typing import TYPE_CHECKING, Any, ClassVar, Final, Literal, Optional, Protocol, TypeVar, Union, cast, overload @@ -954,6 +955,7 @@ class _CallbackCapabilities: has_guardrail: bool = False has_pre_call_override: bool = False has_content_enforcer: bool = False + has_moderation_override: bool = False # Tuple[(resolved_callback, "override" | "apply_guardrail"), ...] # Ordered the same as ``litellm.callbacks``; used to build the streaming # iterator chain without re-scanning per request. @@ -964,6 +966,11 @@ class _CallbackCapabilities: resolved_callbacks: tuple[object, ...] = field(default_factory=tuple) +def _overrides_moderation_hook(callback: CustomLogger) -> bool: + leaf_to_base: Final = takewhile(lambda klass: klass is not CustomLogger, type(callback).__mro__) + return any("async_moderation_hook" in klass.__dict__ for klass in leaf_to_base) + + class ProxyLogging: """ Logging/Custom Handlers for proxy. @@ -2531,6 +2538,7 @@ class ProxyLogging: has_guardrail = False has_pre_call_override = False has_content_enforcer = False + has_moderation_override = False iterator_overrides: Final[list[tuple[Any, str]]] = [] # (callback, kind) resolved_callbacks: Final[list[CustomLogger]] = [] @@ -2549,6 +2557,8 @@ class ProxyLogging: continue if isinstance(resolved, CustomGuardrail): has_guardrail = True + elif _overrides_moderation_hook(resolved): + has_moderation_override = True # Use the same leaf-class ``__dict__`` check as the other hook # capabilities: only callbacks that actually override the hook # contribute to the flag.

That hint was authorized with a hand rolled check that covered only the key allowlist and the team allowlist, so a key restricted by its project's model grant, a team-member restriction, or a key config still routed through the hinted deployment. Greptile flagged the gap as a P1 on the replacement PR. The hint now goes through the same authorize_model_for_key path the batches and files routes use, which runs can_key_call_resolved_model with every rule the proxy enforces elsewhere. Keys those extra rules deny now get a 403 on these routes. The two remaining behavioral differences are edge cases the old check tolerated: a key whose team_models is set without a team_id no longer runs the team allowlist, and a key with a config set skips the key allowlist, both matching the rest of the proxy. The regression test caches a project whose grant excludes the hinted model and asserts the request is refused before any deployment lookup. The two patch() calls on litellm.proxy.proxy_server carry a test-quality-ok reason because can_key_call_resolved_model reads prisma_client and user_api_key_cache through a lazy module import with no injection seam. --- .../vector_store_files_endpoints/endpoints.py | 23 +---------- .../test_vector_store_endpoints.py | 38 +++++++++++++++++++ 2 files changed, 40 insertions(+), 21 deletions(-) diff --git a/litellm/proxy/vector_store_files_endpoints/endpoints.py b/litellm/proxy/vector_store_files_endpoints/endpoints.py index 50a98d01625..97367e59023 100644 --- a/litellm/proxy/vector_store_files_endpoints/endpoints.py +++ b/litellm/proxy/vector_store_files_endpoints/endpoints.py @@ -5,7 +5,6 @@ from fastapi.responses import ORJSONResponse import litellm from litellm.proxy._types import UserAPIKeyAuth -from litellm.proxy.auth.auth_checks import _can_object_call_model, can_key_call_model from litellm.proxy.auth.user_api_key_auth import user_api_key_auth from litellm.proxy.common_request_processing import ProxyBaseLLMRequestProcessing from litellm.proxy.common_utils.openai_endpoint_utils import ( @@ -14,6 +13,7 @@ from litellm.proxy.common_utils.openai_endpoint_utils import ( get_custom_llm_provider_from_request_query, ) from litellm.proxy.openai_files_endpoints.common_utils import ( + authorize_model_for_key, get_credentials_for_model, handle_model_based_routing, prepare_data_with_credentials, @@ -212,26 +212,7 @@ async def _authorize_model_routing_hint( ) -> None: if user_api_key_dict is None: return -
