Thanks for this - exciting launch. Do you have examples of cool applications or demos that the HN crowd should check out?

hi! I've been working on demos where I let Claude Code run for hours at a time on a sandboxed project: https://x.com/ErikSchluntz/status/1894104265817284770

TLDR: asking claude to speed up my code once 1.8x'd perf, but putting it in a loop telling it to make it faster for 2 hours led to a 500x speedup!

I assume you had a comprehensive test suite?

Best demo - it's Claude Code all the way down. Claude Code === Claude Code

YES!! I need infinite credits for infinite Claude Code. Will try it to get Claude to do all my work.

dunno who else to tell this but my pet request for the next version of Claude is to have it say "ensure" and "You're absolutely right!" less often
