What's new?

This release contains some minor improvements:

  • Ollama keep_alive: users now can control the duration for which models remain active in memory when using Ollama (which, by the way, just added Windows support).
  • Streaming support for googleai_dart: the client has been upgraded to support streaming functionality. However, with the release of Google's official google_generative_ai client, we are evaluating the potential deprecation of googleai_dart in favour of the official client if they are on feature parity.
  • Custom instance configuration for OpenAI.

In addition to these updates, we've also started the work to split langchain package into 3 packages. This refactoring aims to enhance modularity and facilitate community contributions.

  • langchain_core: will contain the core abstractions (ie. language models, document loaders, embedding models, vectorstores, retrievers, etc.), as well as LangChain Expression Language as a way to compose these components together. The community can depend on this package to build frameworks on top of LangChain.dart or to interoperate with it.
  • langchain_community: will contain third-party integrations that don't have a dedicated package.
  • langchain: will depend and expose langchain_core and contain higher-level and use-case specific chains, agents, and retrieval algorithms that are at the core of the application's cognitive architecture.
