MODEL FAMILY

OpenAI o-series reasoning models: pricing bands, key models, and next actions

Built for complex reasoning, tool use, and agent workflows, with intent close to real technical decisions. This page is not here to dump names. It compresses the OpenAI route into a family-level entry, then routes people toward latest releases, pricing, alternatives, and live checking.

Family members

Family pages work because they cluster the representative models from one route before deeper decisions begin.
Provider route
OpenAI
This page does not replace the provider page. It translates provider supply into a more searchable family-level entry.
Context band
200K
The context spread across one family often determines which workflows it can really carry inside the global model route.
Input price band
$1.1 - $10
The price band across one family is often closer to a real sourcing decision than any single model.
FAMILY JUDGMENT

OpenAI o-series reasoning models should not behave like a loose list of names. It should help people judge the real decision route inside OpenAI before they move deeper.

Built for complex reasoning, tool use, and agent workflows, with intent close to real technical decisions. The current family input price band is roughly $1.1 - $10, with a context band around 200K, which makes it strong enough to stand as its own high-intent entry page.

The main value of this page is to place the relevant models from one family side by side so users do not keep bouncing through directory pages without making a real judgment.

模型快照更新于 2026-04-21。 Model-family pages cluster representative models, freshness signals, and provider routes into an entry that is easier to search and judge.
NEXT ACTIONS
Once the family is clear, keep moving forward
Open the OpenAI reasoning family provider profile
The family page explains the route. The provider profile explains protocol, base URL, and the broader supply position.
Open provider profile
Inspect provider pricing behind this family
Once someone compares a family seriously, the next step often returns to pricing layers and supply structure.

Continue with OpenAI vs Claude
A natural next step after the family page is to place the route inside a real A-vs-B comparison.
