openai/gpt-6.1-sol
GPT-6.1 Sol is the upgraded mid-tier model in the GPT-6 family, built for complex refactors, deep codebase investigations, and long-running agents. It takes text and image input, holds a 1.05M-token context window (922K max input), writes up to 128K output tokens, and exposes reasoning effort from low through max (reasoning cannot be turned off). Prompt caching is supported, and cache reads bill at 5% of input.
