Our take
Written Sep 4, 2026GPT Chat Latest is OpenAI's flagship hosted chat model that handles text, images and files in a single request. Its 400,000-token limit is among the largest we track, though no benchmark scores are on file to verify quality.
Use this for long-document analysis and synthesis where the 400,000-token limit matters, or for multimodal chat with images and uploaded files. Pick the direct OpenAI route if you need the 37 tokens per second throughput. Skip it if you want downloadable weights, a cheaper tier, or any measured quality data.
The case for it
- 400,000-token request limit, among the largest in the catalogue.
- Broad file and image support alongside text in a single conversation.
The case against it
- Premium pricing on every provider with no budget tier from the same model.
- No benchmark scores on file, so quality claims are unverified in our data.
- Proprietary only — you cannot download the weights to run locally.
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.

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 400K of context.
