About GPT 6 Sol
GPT-6 Sol is OpenAI's cost-efficient high-end model for demanding professional work, coding and agentic tasks. It sits between Astra and Luna, accepts text and image inputs, and provides a 1.05-million-token context with up to 128,000 output tokens.
OpenAI positions Sol for demanding professional workflows with more affordable iteration. Its launch reports substantially improved software engineering and fewer factual mistakes than the previous Sol generation.
The useful distinction is between obtaining a plausible answer and completing work that survives review. For a coding task, examine the changes, the tests and the explanation together; a confident completion message alone is not evidence that a repository is ready.
OpenAI still recommends Astra for the most demanding projects. Sol therefore makes sense when repeated attempts, feedback and refinement matter to the workflow, while the final result remains something you can independently check.
