Why this model scores 84.2
Vendor-reported coding and sustained tool use support strong capability and autonomy. Hosted access broadens deployment. Residual cyber capability despite removed training raises misuse and control concerns, with unverified real-world generalization. Availability remains unknown rather than inferring an open or proprietary licence from hosted access.

News tied to Kimi K3.1 Pro
The model score of 84.2 rates this model's risk profile. The overall Doom Index of 69.1 measures the complete temporally weighted evidence record. These values answer different questions.
Each article's current Doom Index contribution is divided equally among the exact models named on that article. This prevents multi-model evidence from being claimed in full on several model pages. Model risk scores use a bounded temporal offset around their technical profile, but never feed back into the overall index.
