Moonshot AI launched Kimi K2.6 on Monday, an open-source model that the company claims achieves state-of-the-art performance across multiple coding benchmarks, as @Kimi_Moonshot announced. The model is designed specifically for long-horizon coding tasks and agent swarms — the kind of sustained, multi-step programming work that has historically been the domain of proprietary frontier models. It's available immediately with an API.
