hnfm: building a local-first AI podcast generator for Hacker News articles

hnfm builds short podcast episodes from Hacker News posts. I built this with gpt-oss-20b for the OpenAI Open Model Hackathon. It uses:

- Hacker News Firebase API

- Firecrawl for scraping content

- FastAPI, celery, langchain, redis, Nuxt.js

- local inference using: gpt-oss-20b, nari-labs/dia, InvokeAI, Flux Krea [dev], WhisperX, RTX 4090

There are a bunch of similar tools that can generate content from Hacker News articles but none of them checked all of the boxes.

I'll run my hnfm tool against this post and then upload the video that it creates to YouTube and share the link here or in the comments.
