Kimi K3.1 Pro is honestly super impressive for an open-weight model. On par with Fable 5.1 and Gemini 4 Argon.

Seriously, this is such an insane release, I did not expect this:
Kimi K3.1 Pro beats every listed US frontier model on 6 of 14 benchmarks in Moonshot’s evaluations.
At $2 per million input tokens and $10 per million output tokens, its standard token rates are 50% below Opus below GPT-6 Astra ($10/$50!!)
In other words: SOTA much cheaper, local running (with enough compute)
