Our take
Written Aug 2, 2026Palmyra X5 is a hosted-only text model built for very long documents, with a one-million-token request limit that exceeds anything else in our data. It is a niche choice for enterprises that need that exact span and can accept a premium price without measured quality evidence.
Choose this when your workflow genuinely needs a one-million-token request limit and no alternative in our data matches that span. Use it on Amazon Bedrock if you need throughput at a known rate of 17 tokens per second. Skip it if you want benchmark-backed quality claims, faster output, or a lower price point.
The case for it
- One-million-token request limit — no other figure in this record approaches this scale.
- Available from two tracked hosts, including Amazon Bedrock with disclosed throughput.
The case against it
- Premium output pricing with no benchmark scores in our data, so there is no measured basis to claim competitive performance.
- Slow throughput on the only measured endpoint, at 17 tokens per second on Amazon Bedrock.
- Hosted only, with no published parameter count or architecture details.
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 Palmyra X5 — so there is no intelligence, coding, agentic or writing score to show you, not a low one, none.

What each host's API supports
