Overview
What GPT-6.1 Sol is for
An OpenAI model accepting text and images and producing text.
Read the full editorial overview
When to shortlist it
Compare GPT-6.1 Sol by its exact API identifier, input types, output ceiling and standard token rates. A long context window is a documented capacity, not proof that the model will solve a particular task reliably.
What to compare before choosing
Use your own evaluation cases before selecting it. Long prompts, caching, tools and service tier affect cost; do not apply the standard short-prompt rate to every request.
The 1,050,000-token context window and 128,000-token output ceiling are different limits. Long prompts and premium service tiers change token rates.

This profile summarizes the linked official documentation checked on 18 October 2026. It is not a hands-on test or a measured performance ranking. The named plans and model identifiers keep their own scope. Confirm account access, billing terms, taxes and any extra charges before buying.
