What it does

Convert each PDF manual to Markdown with docling, LLM-extract a typed summary — classes, methods, arguments — and store it in Postgres — in plain async Python. Manuals are full of structure laid out for humans, not machines; this pulls it back out into a nested schema. Manuals, datasheets, and reference docs are full of structure — classes, functions, parameters, defaults — laid out for humans, not machines. This pipeline pulls that structure out: convert each PDF to Markdown with docling , LLM-extract a typed summary of the module it documents, and store the result in Postgres. You declare the transformation in native Python and your own types — target_state = transformation(source_state)…from github.com

    Just to clarify the background a bit. This project wasn’t planned as a big standalone release at first. On January 16, Ollama added support for an Anthropic-compatible API, and I was curious how far this could be pushed in practice. I decided to try plugging local Ollama models directly into a Claude Code-style workflow and see if it would actually work end to end. Here is the release note from Ollama that made this possible: https://ollama.com/blog/claude Technically, what I do is pretty straightforward: - Detect which local models are available in Ollama. - When…

    Hi HN A few folks and I have been working on this project for a couple weeks now. After previously working on the Docker project for a number of years (both on the container runtime and image registry side), the recent rise in open source language models made us think something similar needed to exist for large language models too. While not exactly the same as running linux containers, running LLMs shares quite a few of the same challenges. There are "base layers" (e.g. models like Llama 2), specific configuration to run correctly (parameters, temperature, context window sizes etc). There's…
