Anthropic's Claude Opus 5.5 (Max) secured the #1 spot in the Image-to-WebDev Arena benchmark with 1749 points, outperforming GPT-6 Astra. Its sibling model, Claude Sonnet 5.5 (xHigh), ranked second with only a 9-point gap but offered significantly better cost-efficiency at $8/M compared to Opus's $16/M. Both models landed on the Pareto frontier, demonstrating optimal trade-offs between performance and cost for image-to-code generation and agentic workflows.
