Moonshot releases weights for Kimi K3

Moonshot AI has released the weights and technical report for Kimi K3, its large openweight model. The company says the model can now be downloaded and run by anyone with the necessary GPU resources, making it the largest model of its kind to be released with open weights. Kimi K3 first drew attention earlier this month after performing competitively with other top AI systems on several benchmarks. Although the weights are now public, the model remains difficult to run locally because of its size and hardware requirements. The release also opens parts of Moonshot’s stack, including attention kernels and agent infrastructure, under a license that allows others to host and sell access to K3. The move comes amid broader debate over openweight AI, model security, and concerns from U.S. officials about possible model distillation.
