langchain-openai version 1.4.1 has been released with three key updates: support for LangSmith gateway configuration through environment variables across Anthropic, Fireworks, and OpenAI integrations, and a correction to the gpt-5.3-chat-latest profile. This release enables better integration with LangSmith monitoring and fixes a profile naming issue in the OpenAI provider.

Key Points

  • LangSmith gateway can now be configured via environment variables for OpenAI, Anthropic, and Fireworks integrations
  • Environment variable support simplifies deployment and configuration management without code changes
  • Fixed incorrect gpt-5.3-chat-latest profile definition in OpenAI integration
  • Profile correction ensures accurate model selection and API compatibility
  • Release maintains backward compatibility while adding new configuration flexibility
  • Multi-provider support (OpenAI, Anthropic, Fireworks) indicates unified gateway approach across LLM providers
