Moonshot AI Releases Kimi K3.1 Pro Open-Weight Model
Moonshot AI has released Kimi K3.1 Pro, the first model in its K3.1 series and its most capable 3T-class open-weight model, with a 1-million-token context window, 2.8T total and 104B active parameters in a multimodal MoE design. A post-trained version of Kimi K3 with larger post-training compute, it improves on coding, 3D creation and financial research, scoring 65.7% on Terminal-Bench 4.0 and 92.7% on BenchCAD with tools. A Highspeed variant runs 2-3x faster. Both are available on Kimi's platforms and API; full weights are due by November 4.

Microsoft Says Its Medical AI Outperforms Doctors in Diagnosis
Microsoft says its MAI-DxO diagnostic system more than doubles practicing doctors' accuracy on difficult cases, in a study published Thursday in Science. On 304 complex New England Journal of Medicine cases, it reached 83.2% accuracy versus 36.1% for generalist physicians with reference tools. The system uses AI agents that propose diagnoses, order tests and challenge each other. Microsoft plans to begin testing at Beth Israel Deaconess Medical Center in Boston within a couple of months.
