My thinking was models, esp Opus 5.5 can just hill-climb as long as you give them something achievable and a clear metric to improve on. So here's something I don't even have a clue how it exactly works.

The training itself happened in my basement 4070ti super over a day or so.

And yes I know its Opus slop, but still really cool how things I never thought possible unless you're an ML engineer is available to a run of the mill web-dev guy.

Thanks to this tweet from Sahil for even showing how the initial idea worked to distill Kokoro in the first place. https://x.com/sahilmdkr/status/2112212041045889409
