Kimi K3
Same categoryMoonshot's 2.8T open-weight MoE with always-on thinking and native video understanding
Moonshot's Kimi K3 is a massive 2.8T-parameter open-weight mixture-of-experts model activating 104B parameters per token, built with quantisation-aware training and published with MXFP4 weights. It matches MiniMax-M3's 1M-token context and multimodal capabilities, pairing video and image parsing through a 401M-parameter vision encoder with high agentic marks including 88.3 on Terminal-Bench 2.1 and 91.2 on BrowseComp.
Best for: Teams with distributed infrastructure seeking top-tier terminal and browser benchmark execution alongside native vision processing.
Consider: Hosting is substantially more demanding due to the 2.8T parameter size, its first-party API starts higher at $3.00 per million input tokens, and reasoning tokens cannot be disabled, mandating that every call pays the $15.00 output rate.
