Kimi AI - Now with K2.5
👋 Hello from Kimi Team!
Introducing Kimi K2 Thinking: 1T Open-Source Reasoning Model. SOTA with 44.9% HLE, 60.2% BrowseComp. (not just open-source SOTA)
> Trillion-param MoE, trained for $4.6M, 4x cheaper than peers.
> INT4 inference: 4-bit quantized, <1.2s latency @ 256K context.
> Full step-by-step reasoning, 200+ tool calls, self-correction (GPT-5 level), fully open (MIT), OpenAI-compatible API, weights live on huggingface today, agentic mode next week.
We're thrilled to ship a SOTA model that's fully open. Can't wait to see what you all build! :)

Hi everyone!
The K2 model from July was already strong, but it wasn't a "Thinking" model.
Kimi K2 Thinking is a new generation thinking agent model, built on Moonshot's "model as agent" philosophy. The key difference is that it natively understands how to "think while using tools."
It can build a real, functional Word editor:
And it can also create a world of complex, gorgeous voxel art:
@zaczuo Would be cool if it could team up with other agents to tackle bigger stuff

Woah, quantized INT4 inference is a big deal here! Congrats on the launch!

Super responses! But why did you focus so much on slides?
It’s a bit inconvenient that you can’t use it without registering. You even need to sign up for the first search. But the project is interesting anyway!
