Kimi K2.6 Is Here: The Open-Source AI Model Tying GPT-5.5 on Coding
Kimi K2.6 is the new open-source AI model from China’s Moonshot AI, released on April 20, 2026. It just tied GPT-5.5 on the toughest coding benchmark in the industry, at roughly 80% less per million tokens. With 1 trillion total parameters, 32 billion active per token, and a 256K-token context window, K2.6 is now the #1 open-weight model on the Artificial Analysis Intelligence Index. In this article you will find what Kimi K2.6 actually does well, where it still loses to Claude Opus 4.7 and GPT-5.5, exactly how much it costs, and the simplest ways to use it on a Mac without renting your own GPU. We will also cover […]
