    - The "Django" level: additionally handle how data is indexed for RAG, standard patterns of connecting the pieces, possibly GUI, support for plugins.

    It seems langchain and llamaindex are aiming to be the latter, and I'm building https://magentic.dev to be the former. I'd be interested to get your take on whether these abstractions would allow you stray from the narrow path while still being helpful!

    If you are using Python, check out the package I've been building, magentic https://github.com/jackmpcollins/magentic It supports structured outputs and streaming, and aims to avoid making unnecessary abstractions (but might require some more understanding of LLM patterns as a result).

    Also recently released is pydantic-ai, which is also based around pydantic / structured outputs, though works at level of "agents". https://github.com/pydantic/pydantic-ai

    I'm building magentic for use cases like this!

    https://github.com/jackmpcollins/magentic

    It's based on pydantic and aims to make writing LLM queries as easy/compact as possible by using type annotations, including for structured outputs and streaming. If you use it please reach out!

    I haven't used LangGraph myself, but the latest magentic release is compatible with it if you'd like to check out the examples here https://github.com/jackmpcollins/magentic/issues/287
  • I'm puzzled how anyone trusts ChatGPT for code
    4 projects | news.ycombinator.com | 8 May 2024
    I'm building magentic https://github.com/jackmpcollins/magentic which has basically this syntax, though it queries the LLM to generate the answer rather than writing + running code.
