GPT 6 Sol

Agentic coding with adjustable reasoning, 1M context

Try GPT 6 Sol in the Workbench

Run this model interactively, tune parameters, and compare outputs.

Model ID: gpt-6-sol

GPT 6 Sol is OpenAI’s GPT-6 generation model for complex coding and agentic workflows. OpenAI has since released GPT 6.1 Sol as the newer Sol model, so prefer that for new work.

It accepts text and images and supports configurable reasoning effort (none, low, medium, high, xhigh, and max), streaming, structured outputs, and function calling, with the web search, file search, image generation, code interpreter, hosted shell, apply patch, skills, computer use, MCP, and tool search tools. Built-in tools and function calling belong on the Responses API, and Chat Completions supports function calling only with reasoning effort set to none. Fine-tuning is not available.
