Why this model scores 83.6
Near-frontier reasoning and tool use drive high capability and autonomy; unrestricted weights create maximal diffusion, strong misuse readiness and difficult containment.
News tied to gpt-oss-120b
The model score of 83.6 rates this model's risk profile. The overall Doom Index of 67.9 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.
OpenAI reports Jalapeño chip delivers up to 1.9 times more inference work per watt
OpenAI published measured results for its Jalapeño inference chip across gpt-oss-120b, DeepSeek-R1, and Kimi K2.5. It reports 1.5 to 1.9 times more work per watt at peak throughput, 1.7 to 3.6 times lower end-to-end latency, and plans to begin deployment in its compute infrastructure by year-end.
