Introducing Spreadsheet Arena! Models now go head-to-head building real spreadsheets on Design Arena, and the first leaderboard is live. The top 3 models are nearly neck and neck: Claude Fable 5.1 by @AnthropicAI (1371), GPT-6 Astra (xhigh) by @OpenAI (1370), and Claude Opus 5.5 by @AnthropicAI (1358). Then comes a 108-point drop to #4 Claude Sonnet 5.5 (1250). Only 13 points separate the top 3, but there's a clear gap between them and the rest of the field.
