Our take
Written Aug 3, 2026GPT-5.4 Pro is OpenAI's premium multimodal model that can handle up to 1.05 million tokens in a single request, accepting text, images and files. It is positioned for complex document analysis where context size matters more than cost, with a tiered price structure that offers a lower-cost entry point alongside a premium option.
Pick this for massive-document or multimodal analysis where the million-token request limit is non-negotiable. Use the standard tier for budget-conscious work; pick premium only for guaranteed Azure throughput. Skip it if you need benchmark scores, fast output, or local hosting.
The case for it
- Exceptionally large request limit for long-document and video-frame workflows, at 1.05 million tokens.
- Tiered pricing with a lower-cost entry point on the same provider.
The case against it
- Extremely expensive at the premium tier, with no quality differentiation proven in our data.
- Very low output speed for the price: three tokens per second at the premium tier on OpenAI, two on Azure.
- No measured quality data in our catalogue.
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-5.4 Pro — so there is no intelligence, coding, agentic or writing score to show you, not a low one, none.

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.
