This is such a underwhelming release by OpenAI.. They've gone backward in a lot of benchmarks The price decrease is the only thing holding them by a thin string!! In Artificial Analysis Coding Agent Index GPT-6 Sol (max) gains 2 points at half the Cost per Task of 5.6 and suprisingly😭GPT-6 Luna (max) drops by 2 points going behind Gemini 3.8 Flash..
