A benchmark screenshot shows Claude Opus 5 leading DeepSwe, but GPT-5.6 sol is only one point behind while costing less and using nearly half as many output tokens.
The post argues that OpenAI has clearly improved model efficiency, since GPT-5.6 sol delivers near-top performance at a lower cost profile than Opus 5 and Fable 5.
