^ Builder here, I used Kimi K3 and agent swarms to turn YC companies into an interactive galaxy. Every star is a startup you can click and explore.

What are the broad strokes of K3's design? What did you learn?

I built this mainly as a qualitative test of Kimi’s frontend capabilities given the strong frontend score on ARENA. Broadly, I’d say it’s quite capable, it even did a ton of validating, took screenshots, identified its own issues, and iterated repeatedly. The entire session was far more rigorous than I expected

Thanks! For me, learning more about the setup for that (mostly autonomous?) build process would be more engaging than spending a minute with the result.

Basically two prompts: 1) One for agent swarms to collect, cross-check, and structure the data. 2) Another to turn the dataset into the interactive galaxy.

I agree though, the autonomous build process is more interesting than the artifact.

Which harness did you use kimi with? opencode?
