  • •The model's hallucination rate dropped from 23.4% to 8.3%.

Moonshot AI has launched Kimi K3.1 Pro, an upgraded version of its AI model, which is set to have its full weights released by November 4, 2026. The model, boasting 2.8 trillion parameters, nearly matches Anthropic's Claude Opus 5.5 in coding tasks, scoring 65.7% on Terminal-Bench 4.0. Notably, Moonshot claims to have removed hacking-related training data to mitigate potential misuse. The model's hallucination rate has significantly decreased from 23.4% to 8.3%. Despite these improvements, K3.1 Pro still trails behind closed models in certain benchmarks. The release comes amid scrutiny from U.S. authorities regarding the use of banned Nvidia chips in its development. Moonshot's proactive measures aim to address safety concerns associated with open-weight models.
