OpenAI models and prices

62 models, 55 with a published price , 3 with open weights · released 2023-05-28 to 2026-07-09.

You can buy from OpenAI directly, or from 22 other hosts

We hold offerings sold by OpenAI itself as well as by independent hosts. Buying direct is not automatically the cheapest route, and it is not automatically the same product either — hosts differ on quantisation, served context window and rate limits.

Measured quality across OpenAI models

Our own probe suite at temperature 0, scored by deterministic checks — no LLM judge and no vendor claim. Measured on request, so most of the catalog is unscored; a blank is not measured, never a low score. Confidence falls when probes could not be read, which happens on models that answer in a hidden reasoning channel.

Open weights from OpenAI

Parameter counts are computed from the published weight files, and licences are what the authors attached — both from the weights registry rather than from any seller. Licence class decides whether you can self-host commercially without signing something.

Who sells OpenAI models

Offering rows per seller across this vendor's models. A seller appearing many times serves many of the models, not the same one repeatedly.

Jobs these models do

Comparison on each model page is restricted to models doing the same job — a price difference between two different jobs is arithmetic rather than advice.

One API for every OpenAI model

VernaOne fronts the sellers on this page behind a single interface, so switching model or host is a config change — with automatic fallback if quality or latency regresses.

Newest first, priced or not. A model with no price is a fact about what its sellers publish, not a gap we are hiding.

Frequently asked

How many models does OpenAI have?

We track 62 OpenAI models across 3 categories, 55 of them with a published price. The list is rebuilt from provider APIs, the vendor's own docs and the weights registry rather than maintained by hand, so new releases appear without us writing about them.

Can I buy OpenAI models directly from OpenAI?

Yes — we hold offerings sold by OpenAI itself (as openai), alongside 22 other hosts. Buying direct is not automatically cheapest: each model page lists every seller with its price and the evidence behind it.

Are OpenAI models open weights?

3 of 62 have a public weights repository. Licence mix: 3 open weights permissive. Licence class decides whether you can self-host commercially without a separate agreement, so check the model page before planning a deployment.
