What is GPT-5.6 Sol?

GPT-5.6 Sol is OpenAI’s frontier model in the GPT-5.6 family. OpenAI recommends it for complex reasoning, coding, and professional work, while the gpt-5.6 alias routes API requests to GPT-5.6 Sol. It accepts text and image input, produces text output, and supports reasoning effort levels from none through max.

  • Large working context: a 1,050,000-token context window for extensive codebases, documents, and project history
  • Long-form output: up to 128,000 output tokens for detailed implementations and deliverables
  • Reasoning and coding: built for complex professional work, technical analysis, and software development
  • Vision input: analyzes images alongside text for document, interface, and visual-context workflows
  • Agent tools: supports function calling, structured outputs, web search, file search, image generation, code interpreter, hosted shell, MCP, and tool search through supported OpenAI APIs

OpenAI lists GPT-5.6 Sol at $5 per million input tokens, $0.50 per million cached input tokens, and $30 per million output tokens. Its documented knowledge cutoff is February 16, 2026. Requests with more than 272K input tokens use higher long-context pricing, so developers should review OpenAI’s current pricing documentation for production workloads.
