OpenAI released GPT-6 Sol on September 22, 2026, as the mid-tier model in its GPT-6 family, priced at $10 per million output tokens alongside $2 input—half the prior GPT-5.6 Sol rate and one-fifth of flagship Astra. Designed for complex coding, agentic workflows, and scalable reasoning with a 1.05M-token context window, it competes directly with models such as Claude Opus 5.5 while emphasizing lower latency and cost for repeated developer use. Trader sentiment for 2026 output pricing hinges on OpenAI’s history of iterative price cuts with scale, competitive pressure from Anthropic and Google, demonstrated benchmark gains on coding and agent tasks, and any upcoming earnings or API updates that could signal further reductions or tier adjustments before year-end.
