GPT-6.1 Sol is OpenAI's upgrade to GPT-6 Sol and sits just below the flagship GPT-6 Astra in the GPT-6 series. It gets close to Astra on agentic coding, computer use and document-heavy professional work at a fraction of the price. Compared with GPT-6 Sol it makes fewer factual mistakes and keeps more reliably to explicit instructions and limits while working through multi-step tasks.

It accepts text, image and file (PDF) input and returns text, and supports tool calling, structured JSON output and streaming. It always reasons before answering, and you choose how hard it thinks with the reasoning effort setting. GPT-6.1 Sol is commonly used for agentic coding, computer-use automation, document-heavy analysis, business workflow automation and long software tasks in real codebases. Hormouz serves it behind an OpenAI-compatible API: point your base URL at Hormouz, drop in a Hormouz key, and existing OpenAI SDK code runs without changes.

Pricing is usage-based: $2 per million input tokens and $10 per million output tokens. There is no fixed monthly fee, and you pay only for the tokens you use. Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.
