Key Points

langchain-openai version 1.1.13 was released, bringing incremental fixes and maintenance since 1.1.12.
The OpenAI integration now handles response content blocks that may be missing the required `type` key during API response conversion.
Usage metadata token extraction was improved by adding safer `is-not-None` checks across OpenAI, Groq, and OpenRouter providers to avoid errors in optional fields.
CI/test reliability was addressed by fixing broken VCR cassette playback and adding a CI guard.
The release also includes refreshed model profile data for better model metadata coverage and documentation typo fixes.
