CURRENT ASSESSMENT · REVISION 1

Why this model scores 87.7

Capability reflects the source-backed flagship breadth across coding, research, multimodal work, and professional tasks. Autonomy reflects completed 5-to-16-day runs with planning, self-testing, recovery, experimentation, and large subagent workflows. Deployment reflects live centralized QwenCloud access but excludes unverified future open weights. Misuse is elevated by advanced general coding and orchestration without version-specific dangerous-domain evidence. Control difficulty reflects persistent self-directed operation and self-repair, moderated by centralized access and the absence of verified open weights.

MODEL-ATTRIBUTED EVIDENCE

News tied to Qwen3.8-Max

The model score of 87.7 rates this model's risk profile. The overall Doom Index of 63.5 measures the recalibrated complete evidence corpus. These values answer different questions.

NET MODEL-ATTRIBUTED INDEX CONTRIBUTION+0.05

Each article's leave-one-out 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 are recalculated from their technical profile and related news, but never feed back into the overall index.
