Moonshot AI releases Kimi K2.6 with long-horizon coding, agent swarm scaling to 300 sub-agents and 4,000 coordinated steps

Moonshot AI has open-sourced Kimi K2.6, a multimodal agentic model built for long-horizon coding and large-scale coordination.

The model uses a Mixture-of-Experts design with tool-use capabilities for autonomous coding, agent swarms, and extended workflows.

Moonshot says Kimi K2.6 performs near or above leading proprietary models on several coding and reasoning benchmarks, including SWE-Bench Pro and Terminal-Bench 2.0.

The release strengthens the push for open, production-ready AI agents that can handle complex software tasks and multi-agent orchestration.
