Claude 3.7 Sonnet

READER SUMMARY

Anthropic's hybrid-reasoning Sonnet model with controllable extended thinking, strong real-world coding and deployment across Claude, Anthropic's API, Amazon Bedrock and Vertex AI.

DOOM SCORE78.8out of 100model risk profile, not the overall index

CURRENT ASSESSMENT · REVISION 2

Why this model scores 78.8

Frontier coding and extended reasoning materially advance capability; integration with Claude Code supports substantial delegated engineering tasks and raises autonomy. Availability across all major hosted surfaces drives near-maximal deployment, while hosted safeguards moderate misuse and control difficulty.

MODEL-ATTRIBUTED EVIDENCE

News tied to Claude 3.7 Sonnet

The model score of 78.8 rates this model's risk profile. The overall Doom Index of 63.2 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.
