Before you choose
Direct API identity
OpenAI documents GPT-6.1 Sol under the model ID gpt-6.1-sol, with Batch as a supported endpoint. It documents no gpt-6.1-sol-pro model, so the Pro-labelled marketplace row is kept separate and is not asserted to be a direct API model ID.

Questions this page answers
Are the GPT-6.1 family models interchangeable?
No. These are exact catalogue rows with separate capability, pricing and rating evidence. Compare the checkpoint, serving endpoint, reasoning settings and required input types. A family name does not establish equivalent behaviour.
How many OpenAI rows are compared here?
2 standard rows, of which 1 have an accepted LMArena general score and 2 have known input and output token rates. 0 related free or batch variants are listed separately.
What do the prices and frontier counts mean?
Prices below are listed US dollars per million input or output tokens, before request-specific context tiers and other billing dimensions. The frontier count comes from the global balanced view. Neither a family price range nor a benchmark difference proves your task will be cheaper or more successful.
How current are the official notes?
The linked family research was reviewed 2026-09-30. That date is separate from each accepted catalogue observation and each vendor’s effective date. An official note applies to its named platform, not automatically to every reseller.
