Pull request overview
This PR updates the OpenAI Responses chat client to handle streaming code interpreter content by yielding deltas incrementally rather than emitting the code in bulk only at the end of the response. This enables real-time streaming of code generation, improving the user experience.
Changes:
- Added streaming support for code interpreter delta updates, creating
CodeInterpreterToolCallContentfor each delta as it arrives - Extracted the Python media type string into a reusable constant (
PythonMediaType) - Added comprehensive test coverage to verify delta streaming behavior and proper coalescing of deltas into final responses

Added handling for StreamingResponseCodeInterpreterCallCodeDeltaUpdate to yield deltas incrementally; inlined code interpreter content creation logic (removing helper method); updated OutputItemDone handler to only yield result content (assuming deltas handled the call content) |
