> an early K3 wrote the majority of the kernels in the late development stages One fact that Western copers don't appreciate is that just like with Mythos-Preview/Fable, Chinese models don't blink into existence at the day of release. K3 in some usable form is months old

underrated gems in Kimi-K3 release: > an early K3 wrote the majority of the kernels in the late development stages > it built a triton-class compiler from scratch, MiniTriton, that delivers performance on par with or better than Triton and torch.compile > then it designed a chip, by a model, for a model, in one 48-hour autonomous run the model is rewriting and optimizing every layer of the stack it runs on: kernels for its own training. A compiler for its own kernels. silicon for its own weights. we're watching software build its own hardware
