Our take
Written Sep 2, 2026Palmyra X5 is a hosted-only text model built for document-scale work, handling up to one million tokens in a single request. It is a niche pick for teams already inside the Writer ecosystem who need that reach, with no measured quality data to judge it against peers.
Pick this when you need to analyse or generate text across documents longer than a million tokens, and you are already committed to Writer's hosted platform. Skip it if you want open weights, multimodal input, any benchmark-backed quality read, or a price you can shop between providers.
The case for it
- One of the largest request limits we track, at 1.04 million tokens.
- Tight ecosystem integration for teams already using Writer's stack.
The case against it
- Premium output rate with no benchmark scores in our data to justify the cost.
- Hosted only by Writer with no provider competition — just two tracked offers.
- Text-only; no image, audio or video input.
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.
