What It Does?

Kimi enables deep, context-rich interactions: you can upload extensive documents or multiple images, ask for step-by-step explanations, generate or debug code, and receive well-reasoned answers to complex queries. Its interface is accessible via web and API, making integration straightforward for custom workflows.

How It Works?

Built on Moonshot’s proprietary LLM backbone, Kimi employs a two-stage pipeline: an encoder expands the input into a high-dimensional representation, then a Muon-optimized decoder generates coherent, contextually accurate responses. Reinforcement learning fine-tunes behavior based on performance metrics.
