Palmyra X 004
No estimate
No hardware requirements for this model
The weights for this model have not been published, so it cannot be downloaded or run on your own hardware at any size. It is reachable only through its provider, and no graphics card changes that.
On record
Full specification
Everything on record for this model. Most of it describes how it was trained rather than how it runs — useful context for judging how much work went into it, and how it compares with models built at a different scale.

What the numbers mean
What this model is
Palmyra X 004 was published by Writer, in the country recorded as United States of America, during October 2024. It comes out of an organisation categorised as industry.
It works in the domain of Language, and is recorded as performing the task of language modeling, Language modeling/generation, Question answering, Code generation, Retrieval-augmented generation.
Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.
Training and provenance
It is tracked in the underlying dataset for one reason in particular: sOTA improvement.
Answers
Palmyra X 004 — common questions
Palmyra X 004— what is it used for?
It works in the domain of Language, and is recorded as handling the task of language modeling, Language modeling/generation, Question answering, Code generation, Retrieval-augmented generation. These are the areas it was designed around; they describe intent rather than a hard boundary.
Palmyra X 004— what GPU do I need to run it?
None. This is a closed model — its weights were never published, so it cannot be downloaded or run on your own hardware at any price. It is reachable only through its provider.
Palmyra X 004— is it open source?
No. Its weights have not been published, so it exists only as a service controlled by its owner.
Palmyra X 004— how many parameters does it have?
It has a parameter count of 150B. Source: https://venturebeat.com/ai/writers-palmyra-x-004-takes-the-lead-in-ai-function-calling-surpassing-tech-giants/. That figure is the total, and it is what decides how much memory the model needs — roughly half a gigabyte per billion at the compression most people use.
Palmyra X 004— who created it?
It was published by Writer, based in United States of America, an organisation categorised as industry.
Palmyra X 004— when was it released?
It was published in October 2024. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.
The other direction
Looking at it from the other side?
This page starts from the model. If you already own a card and want to know everything it will run, start from the hardware instead.
