Our take
Written Aug 3, 2026GPT-5 Image Mini is a hosted-only model from OpenAI that handles text, images and files, and can generate images as well as text. It offers a 400,000-token request limit for long documents and multimodal tasks, with identical pricing across its two providers.
Pick this for long-context image and document analysis, or when you need native image generation alongside understanding. Use it if predictable pricing across providers matters more than arbitrage. Skip it if you need benchmark scores, self-hosting, or verified throughput on every offer.
The case for it
- Among the longest request limits in image-capable models, at 400,000 tokens.
- Identical pricing across both tracked providers, so there is no arbitrage hunt.
- Generates images natively, not only understanding them, from text, image and file inputs.
The case against it
- No benchmark scores in our data — chat, reasoning, coding and vision quality are all unverified.
- Throughput undisclosed on one of two offers; only OpenAI direct lists a figure.
- Weights are not available for download, and the parameter count is unpublished.
How good is it?
We hold no score for this model.
We look for every model we track on every board we watch, and none of them has turned up GPT-5 Image Mini — so there is no intelligence, coding, agentic or writing score to show you, not a low one, none.
Or rent it from someone else
Why this differs from the header. The strip above quotes OpenAI's own list price. This is the cheapest live offer at the widest standard context we hold, whoever is serving it — a reseller undercutting a lab is ordinary commerce, not an error.

Across the 2 listings we hold: 1 say they do not train on prompts, 0 say they do and 1 do not say. 0 appear in the zero-retention registry we check; the rest are unknown to us rather than confirmed either way.
What each host's API supports
From the parameter list each endpoint publishes. Streaming is omitted: nothing we hold reports it, for any model.
