Anthropic launched a Claude connector that lets users query the Anthropic Economic Index directly, allowing people to ask questions about AI adoption across occupations, tasks, and regions. The connector integrates into claude.ai in about a minute and works across all Claude models without installation. Users can now explore real data on how AI is being used in the economy to understand impacts on their own fields and work.
Researchers built a drawing arena where vision models use colored-pencil tools to reproduce target images like the Mona Lisa or create original drawings from text prompts. GPT-5.6 Sol cost $7.74 to draw seven images with high quality, while Claude Fable 5 cost $160 for lower-quality output despite reviewing its work 27 times. Models plateau early and actually degrade their drawings through excessive revision, showing that more self-review doesn't improve final results.
Greptile researchers tested whether AI code review models catch bugs in code written by other models versus their own code, finding both Claude and GPT detect more bugs in code written by the competing model. Testing on 1,000 PRs with 1,500 verified bugs showed Claude Opus achieved 39% recall on GPT-authored code but only 28% on Claude-authored code, while GPT showed the opposite pattern. The team launched Model Inversion, a feature that routes code reviews to the opposite model based on author detection, leveraging the finding that cross-model reviews outperform same-model reviews.
