I've spent 6 months building a network of curious LLM hackers in London who want to push the edge of what we can do.

This Friday we pull GPT apart and rebuild bits by hand. A few weeks back we tackled ARC AGI 2026. Prevoiusly we did fine tuning and making GPT funny.

It is a sort of a guided hackathon (generally I plan goals for the day) and collaborative study group.

Much fun, no money, lots of smart folk asking good questions: https://playgroup.org.uk/
