GPT-6 Sol Pro

GPT-6 Sol Pro is GPT-6 Sol served in pro reasoning mode.

Checked 2026-11-05

GPT-6 Sol Pro is GPT-6 Sol served in pro reasoning mode. OpenRouter describes it as the same underlying model with reasoning.mode set to pro, for higher-quality answers on complex tasks. It was listed on 22 September 2026, a week before the 6.1 refresh. The context window is 1,050,000 tokens. It takes text, images and files and returns text. On 5 November 2026 the price is $2 per million input tokens and $10 per million output, identical to GPT-6.1 Sol Pro. The listing's own cost note says pro mode spends far more tokens, so the real cost per answer is higher than that rate implies. The weights are not published, so it is closed. The limit worth knowing is that a newer sibling now exists at the same price, so unless you have tuned prompts to this version, GPT-6.1 Sol Pro is the more natural pick. It suits difficult coding or analysis where quality beats speed. You reach it through the OpenAI API or OpenRouter. Figures come from OpenRouter's public model list and model page. We have not run it.
