GPT-6 Sol sits between the flagship GPT-6 Astra and the fast GPT-6 Luna. It is aimed at demanding professional work, agentic coding, business automation and computer use, and is especially good at long software tasks inside real codebases. It comes close to Astra's factual reliability for much less money and shares its concise, clear style in technical conversations.

It accepts text, image and file (PDF) input and returns text, and supports tool calling, structured JSON output and streaming. Reasoning can be switched on when a problem needs more thought and left off when speed matters. GPT-6 Sol is commonly used for agentic coding, long software engineering tasks, business workflow automation, computer use and professional writing. 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.
