/ About this event

The loop is already spinning.

More than 80% of Anthropic’s code is written by Claude. Jeff Dean left Google after 30 years to build the loop for science. Direction-setting is increasingly the role left for humans.

This Sunday, we’re hacking self-improving AI systems.

Lilian Weng argues the near-term path to recursive self-improvement may run through the harness, not the model weights. The bottleneck? Evals.

A self-improvement loop is only as good as its evaluator.

That’s the hack: build the loop, build the eval, and see how far it can improve itself.

------------------------------------ ✨What is Sundai✨

Sundai Club is the largest MIT / Harvard AI hacker group that meets every sunday to build a new AI app from scratch by the end of the day.

We had done 110+ hacks back-to-back in the last 2 years - one for every sunday without stopping

------------------------------------ ✨Our mission at Sundai ✨

_"Push the envelope of what is possible to do with AI in a day."_

1. Grow the Best Hackers learn to build fast with AI

2. Build things that matter users / $$$ / github ⭐️s

3. Spread the Hacker Mindset teach the skills that we learn at MIT and beyond

------------------------------------ ✨Our Principles✨

Build. Ship. Shortcuts

- Build: The purpose of Sundai is to get together and build things. Every Sunday. - Ship: get off the localhost. Deploy a simple webapp demo that works on the internet. Go for less, to do more. - Shortcuts: Shortcuts is an ingenious move that a hacker makes to build a system that works. In order to build fast - you always need to think in shortcuts.
