Questions this page answers
Are the GPT-4 and GPT-3.5 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?
6 standard rows, of which 1 have an accepted LMArena general score and 6 have known input and output token rates. 2 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 2026-09-22. 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.
