## Definition

[Kimi K2.6](https://www.kimi.com/blog/kimi-k2-6) is Moonshot AI's April 20, 2026 open-weight flagship — a 1T-parameter Mixture-of-Experts model (32B active, 384 experts, 256K context, native multimodal) released under a [Modified MIT License](https://huggingface.co/moonshotai/Kimi-K2.6) on Hugging Face and via the Kimi API.

K2.6 graduates Moonshot's `Code Preview` branch into a general-availability model built for long-horizon agentic coding: 12+ hour autonomous runs, 4,000 coordinated tool calls, and an `Agent Swarm` architecture of up to 300 parallel sub-agents. It posts 58.6 on SWE-Bench Pro and 54.0 on HLE-with-tools, narrowly topping GPT-5.4 and Claude Opus 4.6 on both.

## Analogy

If Opus 4.6 is a senior engineer you pair with for an hour, K2.6 is a swarm of 300 interns you leave running overnight.

## Why it's emerging now

Moonshot shipped Kimi K2.6 on Apr 20 as open-weight under Modified MIT — the first open model to lead on SWE-Bench Pro (58.6 vs GPT-5.4's 57.7, Opus 4.6's 53.4) and Humanity's Last Exam with tools. More novel than the benchmark: 12-hour autonomous coding runs and 300-agent swarms as first-class features, not wrappers.
