Kimi K3 Release Triggers Compute Crisis and Membership Purchase Limits: Moonshot AI released Kimi K3, an open-source MoE model with 2.8 trillion parameters. Due to a surge in demand, GPU compute capacity became critically tight, leading the company to announce a temporary pause on new subscriptions for C-end users and plans to split standard memberships from programming memberships. K3 demonstrated strong performance in front-end programming and cybersecurity testing, even fixing vulnerabilities that Codex and Fable had rejected due to safety restrictions. This event has sparked deep industry discussions regarding compute bottlenecks and the commercialization paths of open-source models. (Source: 量子位, The Verge, THE DECODER, Hacker News, 机器之心)
