月之暗面发布 Kimi K3.1 Pro，100 万 token 上下文，开放权重将于 11 月 4 日前释出

Moonshot AI released Kimi K3.1 Pro, which supports a 1M token context, and says the full model weights will be released by November 4. A companion model, Kimi K3.1 Pro Highspeed, runs at 2-3x the speed. Both are available from today on Kimi.com, Kimi Work, Kimi Code and the Kimi API.

Why it matters: Moonshot disclosed vulnerability-task results before and after removing cybersecurity training data, giving a concrete comparison for risk control in open weights.
