Our take
Written Sep 4, 2026GPT-4 Turbo Preview is a hosted-only text model from OpenAI with a 128,000-token request limit, released in early 2024. It is positioned for long-document work within the OpenAI ecosystem, though no independent quality scores are available to verify its performance.
Choose this when you need a very large request limit for long documents and are already committed to OpenAI's platform. It suits workflows where budget is secondary to ecosystem continuity. Skip it if you need image, audio or video handling, if you want measured quality data to justify the cost, or if price sensitivity matters.
The case for it
- 128,000-token request limit — among the largest we list for this generation, useful for long-document work.
- Available through two tracked providers, including direct from OpenAI.
The case against it
- No benchmark scores in our data: chat, reasoning, coding and multimodal performance are all unverified.
- Premium pricing without independent quality verification — the same tier as OpenAI's flagship, but no scores held to justify it.
- Text-only; no image, audio or video input or output.
How good is it?
We hold no score for this model.
So there is no figure here for everyday use, coding, agent work or writing. That is a gap in our data, not a low score.
Where to rent it
Prices checked between 9 days and 17 days ago — each listing carries its own date.
OpenAI, direct
The lab is also the cheapest we hold. The strip above and this offer are the same one, so nothing on this page undercuts OpenAI on 128K of context.
