Motivation

Modifications

This pull request streamlines the OpenAI serving layer by eliminating batch request handling from its core entrypoints. This significant refactoring aims to simplify the codebase, making it more maintainable and easier to understand, while also incorporating specific improvements to streaming responses and tool call management.

  • API Refinement: Refactored OpenAI serving entrypoints (for chat, completions, and embeddings) to exclusively handle single requests, removing previous support for batch processing.
  • Code Simplification: Simplified internal request conversion logic (_convert_to_internal_request) across all serving entrypoints by removing batch-specific loops and parameters.
  • Streaming Improvements: Restructured streaming response generation in chat and completion serving into dedicated asynchronous generator methods for cleaner code, and improved tool call ID generation for streaming.
  • Test Updates: Updated unit tests to align with the new single-request model and adopted asyncio.run for proper execution of asynchronous tests.

Checklist

… validation.

This commit refactors the OpenAI serving entrypoints
to handle single requests instead of lists of requests.

This simplifies the code and makes it easier to
understand and maintain.

Ensures that streaming responses including usage data are formatted to match OpenAI's API. Specifically, when `include_usage` is true, it first sends a chunk with `finish_reason` but no usage, followed by a chunk with usage but empty choices. This aligns with OpenAI's specification for streaming responses.

Reorders the streaming chunks to first send a chunk with the
finish reason, followed by a separate chunk with usage information
when `include_usage` is specified. This change aligns the streaming
behavior with the OpenAI API.

Fixes an issue where tool call IDs were not handled correctly during streaming.

The tool call ID is now generated only once per tool call, and subsequent chunks use null ID and name for argument deltas. This ensures correct identification and handling of tool calls in streaming scenarios.

Ensures the stream_buffer is always updated with the latest state.

This change addresses a potential issue where the stream buffer might not reflect the most recent updates, particularly when dealing with delta information in streaming responses. By consistently updating the stream buffer, the code maintains a correct and consistent state throughout the streaming process.

Refactors the `_convert_to_internal_request` methods in the OpenAI serving classes to remove the `request_id` parameter.

The request ID is no longer needed during the conversion process, simplifying the method signatures and internal logic.

Addresses an issue in streaming chat completion where incorrect state was maintained when handling multiple concurrent requests.

The changes ensure that state variables like `is_first`, `stream_buffer`, `n_prev_token`, `prompt_tokens`, `completion_tokens`, and `cached_tokens` are properly tracked for each request by using dictionaries indexed by the request index.

Summary of Changes

This pull request streamlines the OpenAI serving layer by eliminating batch request handling from its core entrypoints. This significant refactoring aims to simplify the codebase, making it more maintainable and easier to understand, while also incorporating specific improvements to streaming responses and tool call management.

Highlights

  • API Refinement: Refactored OpenAI serving entrypoints (for chat, completions, and embeddings) to exclusively handle single requests, removing previous support for batch processing.
  • Code Simplification: Simplified internal request conversion logic (_convert_to_internal_request) across all serving entrypoints by removing batch-specific loops and parameters.
  • Streaming Improvements: Restructured streaming response generation in chat and completion serving into dedicated asynchronous generator methods for cleaner code, and improved tool call ID generation for streaming.
  • Test Updates: Updated unit tests to align with the new single-request model and adopted asyncio.run for proper execution of asynchronous tests.
Changelog
  • python/sglang/srt/code_completion_parser.py
    • Updated import from ChatCompletionRequest to CompletionRequest.
    • Changed generate_completion_prompt_from_request to accept CompletionRequest.
  • python/sglang/srt/entrypoints/openai/serving_base.py
    • Removed List from typing imports.
    • Modified _convert_to_internal_request signature to remove request_id parameter and return a single OpenAIServingRequest.
    • Updated call to _convert_to_internal_request in handle_request to reflect the single-request model.
  • python/sglang/srt/entrypoints/openai/serving_chat.py
    • Removed List from typing imports, added AsyncGenerator.
    • Removed the _validate_request method.
    • Refactored _convert_to_internal_request to process a single ChatCompletionRequest directly, removing batch-related loops and logic.
    • Extracted streaming response generation into a new _generate_chat_stream async generator.
    • Simplified _handle_non_streaming_request and _build_chat_response signatures by removing redundant parameters (cache_report, tool_call_parser, reasoning_parser).
    • Changed tool call ID generation to use uuid.uuid4().hex[:24].
    • Improved tool call ID and function name handling in _process_tool_call_stream for streaming.
  • python/sglang/srt/entrypoints/openai/serving_completions.py
    • Added logging and AsyncGenerator imports, removed Optional.
    • Removed the _validate_request method.
    • Refactored _convert_to_internal_request to handle a single CompletionRequest, removing batch processing logic.

  • python/sglang/srt/entrypoints/openai/serving_embedding.py
    • Simplified _validate_request by removing validation for list of list inputs.

    • Added logic to treat single-element list string inputs as single strings in _convert_to_internal_request.
  • test/srt/openai/test_serving_chat.py
    • Updated calls to _convert_to_internal_request to pass single request objects.
    • Commented out test_tool_call_request_conversion and test_tool_choice_none (pending re-enablement).
  • test/srt/openai/test_serving_completions.py
    • Updated calls to _convert_to_internal_request to pass single request objects.

    • Updated calls to _convert_to_internal_request to pass single request objects.
    • Commented out rid assertions.
    • Wrapped async test methods in asyncio.run(run_test()).
Activity
  • The gemini-code-assist[bot] provided initial automated review comments on type hint updates and argument changes for _convert_to_internal_request across various serving files.
  • The gemini-code-assist[bot] also suggested a fix for stream_buffer not updating in serving_chat.py and a fix for tool call ID handling in streaming.
  • CatherineSue engaged in a discussion about removing the request_id parameter from _convert_to_internal_request (referencing issue [Bug] Inconsistent rid handling in OpenAI-Compatible Server #7374), which was subsequently removed by the author.
  • CatherineSue raised a concern about the change of streaming state variables (is_firsts, stream_buffers, n_prev_tokens) from dictionaries to single variables in serving_chat.py, noting it might break for request.n > 1. The author, JustinTong0323, acknowledged this as a valid point and plans to fix it.
  • CatherineSue also provided feedback on tool call ID generation for streaming, which the author addressed.
  • CatherineSue suggested improvements for serving_embedding.py regarding single-element list string inputs and removal of a validation method.
  • The gemini-code-assist[bot] later raised high-priority concerns that the rid (request ID) is not being correctly propagated and set for GenerateReqInput and EmbeddingReqInput objects in serving_chat.py, serving_completions.py, and serving_embedding.py.
  • The gemini-code-assist[bot] noted that tool call tests in test_serving_chat.py were commented out and should be re-enabled and updated.
  • JustinTong0323 posted a screenshot of local test results.
  • There are still unresolved comments regarding the request.n > 1 issue for streaming state variables and the rid propagation.

@JustinTong0323 serving_completions.py might have the issue with index too.

Refactors the OpenAI completion streaming endpoint to correctly
handle multiple streams. This change addresses an issue where
concurrent streams were not being managed independently, leading
to incorrect output. It introduces per-stream buffers and token
counters to ensure accurate and isolated responses for each stream.

Hi @justHungryMan , the original online batch support is not production-wise ready. We plan to switch to an offline batch support, please check out #7427 for details. Welcome to leave comments there!
