Moonshot AI Releases World's Largest Open-Source System
Moonshot said the 2.8 trillion-parameter system can handle long coding and reasoning tasks and will be released with full weights later this month.
- On Thursday, July 16, 2026, Chinese AI lab Moonshot released Model Kimi K3, an Open Frontier Intelligence model featuring 2.8 Trillion Parameters now available across Kimi Work, Kimi Code, and the Kimi API.
- The release aims to close the performance gap between Chinese models and frontier counterparts like OpenAI's ChatGPT and Anthropic's Opus, with Financial Times reporting the model is expected to perform at par with or surpass Anthropic's Opus 4.8.
- Model Kimi K3 utilizes Kimi Delta Attention and Attention Residuals to improve information flow across sequence length and model depth, enabling up to 6.3x faster decoding in Million Context lengths.
- Developers scaled up Mixture of Experts sparsity, activating 16 out of 896 Experts when paired with a Stable LatentMoE framework, yielding an approximate 2.5 improvement in overall scaling efficiency.
- Moonshot is reportedly raising capital at a $31.5 billion valuation, building on a $2 billion round in May, and will release Open Weights for the model by July 27, 2026.
