Moonshot will release open weights for its Kimi K3 AI model on July 27, 2026, following a firm platform announcement. The release shifts access from a restricted window to public availability, with researchers preparing to test inference capabilities on standard benchmarking frameworks.

Cloud infrastructure provider Modal confirmed it will provide day-zero support for the model upon launch. Early benchmark runs on ErdosBench indicate the model processes evaluation tasks across 19 batches of 12 problems each in concurrent sessions. The scheduled drop aligns with a global rollout window occurring less than 24 hours from initial announcements.

meanwhile time in China: 00:32 Monday, July 27, 2026 Strictly under 24 hours until an open frontier model

@teortaxestex

tbh not a great look that Kimi's timeline is implicitly tied to the United States. In 22.5 hours, it'll be 11 PM in China.

Finally I've started running Kimi K3 on ErdosBench. I already love how it looks in terminal. Kimi has divided the set into 19 batches, 12 problems each, and runs it all concurrently. "Actually - WAIT." "Hmm, hold on, maybe..." https://t.c
