- R · What Makes It Special
- Kimi K3, Moonshot AI's open-weight native multimodal model and, by its account, the world's first open 3T-class model: 2.8T total and 104B active parameters, with 16 of 896 experts used per token, Kimi Delta Attention and Attention Residuals, which Moonshot says give about 2.5x better scaling efficiency than Kimi K2, a 1M-token context and MXFP4 quantization-aware training. Moonshot says it still trails Claude Fable 5 and GPT 5.6 Sol; its API costs $3/$15 per million tokens ($0.30 cached input).
