Adjusted error messages for missing API base and key. Updated health check URL construction to pass model as a query parameter. * Enhance OpenAI Realtime handler tests to ensure model parameter inclusion in WebSocket URL. Added new tests to verify correct URL construction with model and additional parameters, preventing 'missing_model' errors. Updated existing tests for consistency. * Remove debug print statements for API base and key in OpenAIRealtime handler to clean up the code. --------- Co-authored-by: Ishaan Jaff --- litellm/llms/openai/realtime/handler.py | 16 +- litellm/proxy/proxy_server.py | 4 +- litellm/realtime_api/main.py | 2 +- litellm/router.py | 7 +- .../test_fireworks_ai_translation.py | 1 + tests/llm_translation/test_openai_realtime.py | 298 ++++++++++++++++++ tests/local_testing/test_completion_cost.py | 6 +- tests/local_testing/test_text_completion.py | 1 + .../test_router_helper_utils.py | 8 +- .../realtime/test_openai_realtime_handler.py | 123 +++++++- 10 files changed, 441 insertions(+), 25 deletions(-) create mode 100644 tests/llm_translation/test_openai_realtime.py diff --git a/litellm/llms/openai/realtime/handler.py b/litellm/llms/openai/realtime/handler.py index aca32e1404a..e0c85d18178 100644 --- a/litellm/llms/openai/realtime/handler.py +++ b/litellm/llms/openai/realtime/handler.py @@ -1,5 +1,5 @@ """ -This file contains the calling Azure OpenAI's `/openai/realtime` endpoint. +This file contains the calling OpenAI's `/v1/realtime` endpoint.
