Seriously, this time it really feels and shows that the gap between US frontier closed source and Chinese open weight models are closing.
Anthropic should release fable 5.5 asap to proof they still have a significant lead.
It’s crazy how much china caught up.
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 5.5 ($4/$20 !!) and 80% below GPT-6 Astra ($10/$50!!) In other words: SOTA much cheaper, local running (with enough compute)在 X 查看被引用的帖子
