From b46407fa7655b7bc029a49a3e465568996b0dcd7 Mon Sep 17 00:00:00 2001 From: Henry Wang Date: Sun, 28 Sep 2025 15:33:06 +0800 Subject: [PATCH 01/11] feat(gemini): Add full support for native Gemini API translation This commit implements a complete, end-to-end fix for the native Gemini API translation feature, allowing requests to be correctly routed to other model providers via `model_group_alias`. The original implementation was broken, causing `systemInstruction` and `tools` to be dropped from requests. This was resolved by refactoring the Gemini endpoint to use a dedicated translation path, similar to the Anthropic adapter. Additionally, this commit hardens the streaming response adapter to correctly handle tool calls generated by the newly-fixed request path. Key improvements to the response handling include: - Replaced the fragile `id`-based tool call tracking with a robust `index`-based accumulation logic. - Fixed a memory leak and improved logging in the stream finalization process. - Prevented empty, non-compliant chunks from being sent to the client during tool call streaming. - Optimized the accumulator to skip and log superfluous empty chunks sent by some models. --- litellm/__init__.py | 1 + litellm/google_genai/adapters/handler.py | 54 +++- .../google_genai/adapters/transformation.py | 305 +++++++++++------- litellm/google_genai/main.py | 31 +- litellm/main.py | 20 ++ litellm/proxy/common_request_processing.py | 5 + litellm/proxy/google_endpoints/endpoints.py | 129 ++------ litellm/router.py | 17 +- 8 files changed, 294 insertions(+), 268 deletions(-) diff --git a/litellm/__init__.py b/litellm/__init__.py index 02bb773d268..20f0d5b2e50 100644 --- a/litellm/__init__.py +++ b/litellm/__init__.py @@ -1355,6 +1355,7 @@ from litellm.litellm_core_utils.cli_token_utils import get_litellm_gateway_api_k ### PASSTHROUGH ### from .passthrough import allm_passthrough_route, llm_passthrough_route +from .google_genai import agenerate_content ### GLOBAL CONFIG ### global_bitbucket_config: Optional[Dict[str, Any]] = None diff --git a/litellm/google_genai/adapters/handler.py b/litellm/google_genai/adapters/handler.py index dcf707ebd51..2e3d7a836d2 100644 --- a/litellm/google_genai/adapters/handler.py +++ b/litellm/google_genai/adapters/handler.py @@ -72,15 +72,26 @@ class GenerateContentToCompletionHandler: completion_response = await litellm.acompletion(**completion_kwargs) if stream: -
