Forensic Summary
Moonshot AI has released the weights for Kimi K3, a 2.8 trillion parameter mixture-of-experts model (1.56TB), distributed under a restrictive 'open weight' licence that requires a separate commercial agreement for large MaaS operators. The public availability of weights at this scale materially lowers the barrier for adversarial fine-tuning, jailbreak research, and model-theft-adjacent supply chain attacks. Defenders deploying or downstream of K3 should assess licence compliance risk alongside the standard open-weight threat model.
