Our take
Written Sep 4, 2026GPT-5.4 Pro is OpenAI's proprietary flagship that handles up to 1.05 million tokens in a single request, accepting text, images and files. It is built for long-document and multimodal analysis, though its quality is unverified in our data and it carries a steep output cost.
Choose this when you need to analyse very long documents or combine images, files and text in one workflow, or when your enterprise requires Azure infrastructure. Skip it if budget matters more than context length, if you need measured quality scores, or if fast output at lower cost is essential.
The case for it
- One of the largest request limits we track, at 1.05 million tokens — rare for long-document work.
- Multimodal input: accepts text, images and files together.
The case against it
- Premium output cost that rises sharply on secondary providers.
- Slow throughput on lower-priced tiers: 3–4 tokens per second.
- No benchmark scores recorded, so quality claims are unverified in our data.
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.
