Summary

Fixes #778.

OpenAIModel now accepts stream=False as a model config option and keeps the older params={"stream": False} path working. When a non-streaming chat completion is requested, the provider converts the returned completion into the same Strands stream events that callers already consume.

To verify

  • python -m pytest tests\strands\models\test_openai.py -q
  • python -m ruff check src\strands\models\openai.py tests\strands\models\test_openai.py
  • python -m ruff format --check src\strands\models\openai.py tests\strands\models\test_openai.py
  • git diff --check
