World of AI Bench just dropped and the ranking is exactly the script everyone already wrote: Opus 5.5 GPT-6 Astra Claude Sonnet 5.5 GPT-6 Sol Sonnet 5.5 beating Sol was the expected result. Losing to Astra was too. What the composite hides: Sonnet 5.5 is very token-heavy. Same $2/$10 list price as SoL, but it burns a lot more tokens to sit 0.4 points ahead. Tight top 4. Ugly token bill if you actually ship Sonnet 5.5 at volume. http://woaibench.ai
