OpenAI Models

Q: Which OpenAI model should I start with?

auto is free on input — the cheapest entry here that declares tool calling, and it carries a 1M context. Move up to o1-pro when answer quality matters more than cost, or to gpt-5.5-free for long-form reasoning.

Q: How is cached input billed?

The Cache read column is the rate for input tokens served from the prompt cache — for example gpt-6.1-sol bills cache hits at 5% of the input rate and gpt-6.1-terra bills cache hits at 5% of the input rate. Cache write is the surcharge for putting a prompt into the cache in the first place, and only a few upstreams bill it separately. A dash in either column means the catalog carries no cache rate for that model, so plan on paying the full input rate.

Which models that traffic went to

Share of 1359B tokens. 55 models with traffic report no token counts and cannot be ranked here, including gpt-4o-mini-tts and whisper-large-v3 — they are in the request view.

The two views disagree on purpose: a model can take a large share of the calls and a small share of the tokens — many short requests — or the reverse. Which one matters depends on whether your cost is driven by call volume or by prompt length. Measured on AIHubMix over the last 30 days, counting the 144 model IDs listed on this page; traffic routed through upstream-specific IDs that are not in the public catalog is not included.

Prices are USD per million tokens; cache read and cache write are the rates for prompt-cache hits and for writing a prompt into the cache. Throughput and latency are measured on AIHubMix — the same figures the model detail page shows — not vendor claims. A dash means the catalog does not publish that field for that model, which is not the same as the model not supporting it.

OpenAI on AIHubMix

Which OpenAI model should I start with?

auto is free on input — the cheapest entry here that declares tool calling, and it carries a 1M context. Move up to o1-pro when answer quality matters more than cost, or to gpt-5.5-free for long-form reasoning.

Which of these models reason before answering?

43 of the 144 models here declare a reasoning phase — they work through the problem before producing an answer, which helps on multi-step problems at the cost of extra output tokens. Use the Reasoning filter above the table to see them. The catalog does not record anything further about how they differ, so this page does not sort them into families.

Why are there several entries for the same model?

Because each row is a route you can call, not a model release. Some IDs name an upstream (azure-, alicloud-, cc-), and some differ only in capitalisation, kept so older integrations keep working.

The catalog does not carry a field saying which of those a given row is, so this page does not sort them into buckets it would have to invent. Every row shows that route’s own price, context and speed — compare those directly, and open a model to see the upstreams that serve it.

How is cached input billed?

The Cache read column is the rate for input tokens served from the prompt cache — for example gpt-6.1-sol bills cache hits at 5% of the input rate and gpt-6.1-terra bills cache hits at 5% of the input rate. Cache write is the surcharge for putting a prompt into the cache in the first place, and only a few upstreams bill it separately. A dash in either column means the catalog carries no cache rate for that model, so plan on paying the full input rate.

Do I need a separate OpenAI account?

No. One AIHubMix key covers every model on this page, and switching between them is a change to the model string — billing, rate limits, and logs stay in one place.
