Source: The Economic TimesAlso reported by The Economic Times

Moonshot AI released Kimi K3.1 Pro, a 3-trillion-parameter open-weight model with a 1-million-token context window, on Kimi.ai, Kimi Work, Kimi Code and the Kimi API, and plans to publish the full weights by 4 November. The company said it removed cyber-related data from the model’s training corpus and reinforcement-learning environments to reduce its cyber-offensive capabilities. K3.1 Pro scored 81.0% on Moonshot’s internal cyber benchmark, against 90.5% for a version without those measures.

Why it matters

Moonshot AI says Kimi K3.1 Pro scored 65.7 per cent on Terminal-Bench 4.0, above GPT-6 Astra at 58.2 per cent and just below Claude Opus 5.5 at 66.4 per cent.
