@LatticeProxy @theo http://x.ai did not open-source any model. Grok build is just the harness, like Claude Code. They open-sourced the harness, not the model.

Here are a few benchmark scores of K3 that have been officially confirmed This is a Fable/Sol class model that is strictly better than Opus 4.8 across the board at Sonnet pricing. Insane

I know everyone throws this around casually now but I genuinely have not felt a model release that was as impactful as this since DeepSeek R1

Normally I don’t comment on rumors, but if Kimi K3 actually beats out Opus 4.8 that’s nuts Also hearing Opus 5 might drop?
