About this model

GPT-6.1 Sol is OpenAI's advanced reasoning model designed to deliver near-GPT-6 Astra capability at a lower cost for complex coding, computer use, agentic workflows, and professional knowledge work. It supports a 1.05M-token context window and up to 128K output tokens, enabling it to work across large codebases, documents, and long-running multi-step tasks. The model supports configurable reasoning effort, image understanding, function calling, structured outputs, web and file search, code execution, computer use, hosted shell, MCP, and other agentic tools through the Responses API. GPT-6.1 Sol is optimized for applications that require strong reasoning and tool use while balancing capability, speed, and serving cost.
