The Flagship That Is Half Price Only If You Ask OpenAI Directly
The half-price flagship is only half price if you buy it from the maker, and that is the whole story. OpenRouter lists GPT-5.6 Sol at $2.50/$15 per million with a 1M context, released July 9, 2026. OpenAI calls it the flagship for complex reasoning and long-horizon problem solving, the model you reach for when agents need to stay on track. Yet the same model on Azure and Amazon Bedrock sits at $5.00/$30.00 and $5.50/$33.00 respectively, with OpenAI's own pipe showing as 50% off beside them.
