OpenAI and Anthropic release new models, shifting the comparison toward cost per accepted task.
Summary
OpenAI released GPT-6 Sol and Luna on September 22, while Anthropic introduced Claude Opus 5.5. The announced rates differ sharply, as do context, caching and deployment conditions. Anthropic’s estimated savings for typical workloads are not a uniform token-price reduction, and neither company’s benchmarks replace an evaluation on real internal tasks.
