Kimi K3 is Moonshot AI's flagship model, a 2.8T-parameter MoE released on 2026-07-16 with a 1M-token context window and built-in thinking exposed through reasoning_content. It supports vision input, tool use, prompt caching, and web search, making it suited to long-horizon agents that need to read documents and images, search the web, and reason across very large inputs. It runs directly on the OpenAI protocol, and over the Anthropic protocol no explicit thinking parameter is required. Context: 1M tokens, output: 1M. Available via OpenAI and Anthropic protocols through Ofox.
