GPT-5.2 family

GPT-5.2 variants retain their own model IDs, prices and rating coverage. API usage is separate from a ChatGPT subscription; Codex and Pro labels need endpoint-specific interpretation.

This collection organises accepted catalogue identities. It does not certify equal weights, a shared licence, benchmark equivalence or current availability on every serving platform.

USD per 1M tokens. In / out are listed base rates; expand billing conditions before planning a request. LMArena scores measure the general preference board, not success on your engineering task. Unknown stays unknown.

Free and batch variants

These rows have different access or processing conditions. They are excluded from the standard-row counts above. A variant without a standard base remains a separately named variant.

Questions this page answers

Are the GPT-5.2 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?

4 standard rows, of which 1 have an accepted LMArena general score and 4 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.
