What’s New in This Update
The langchain-openai package has been bumped from version 1.5.2 to 1.6.0, with a focus on making errors easier to understand and manage.
The core library now includes standard exception types for model-related failures, so self-hosted users can catch and respond to errors more consistently across different providers. Additionally, the OpenAI integration will raise a clear, descriptive error if an API response arrives in an unexpected format while building chat results, instead of failing silently or with a confusing internal error.
