}'What is Palmyra X5 good for?
Palmyra X5 is one of Writer's models. Put "writer/palmyra-x5" in the model field and the rest of your code stays as it is. Palmyra X5 keeps 1,040,000 tokens in view at once, and that number is what caps the conversation history in your product. A single response can run to 8,192 tokens. On price it sits in the "mid-range" band — cheaper than 297 and dearer than 109 of the other paid models in the catalogue.
This one handles text only. If you need function calling or image understanding, pick another model from the same catalogue — swapping is a one-line change.
Pricing is 174,075 toman per 1M input tokens and 1,740,750 per 1M output tokens. A 1,000-word round trip on Palmyra X5 lands near 2,489 toman. You are always charged for the usage the request actually reported, never for the estimate, and a failed request costs nothing.
The closest alternative with the same capabilities from a different provider is Magnum v4 72B: Palmyra X5 works out roughly 1.1× cheaper, and its context window is larger. Both run on the same key and the same code, so trying the other one is a single string change.
To make the figure concrete: 100,000 toman of credit buys roughly 40 thousand-word requests on Palmyra X5, and every 1,000 toman is about 402 words of round trip. A job with one million input tokens and one million output tokens comes to 1,914,825 toman in total. Filling this model's 1,040,000-token window costs 181,038 toman on the input side alone, which is the real reason to keep conversation history short.
Among the less common parameters it accepts top_k — all through the standard request body. It does not support include_reasoning, reasoning, response_format, tool_choice, which most models here do, so test before switching if your code relies on them. By context size the nearest option from another provider is GPT-4.1 at 1,047,576 tokens.
Good fits: product chatbots and internal assistants, where cost and quality have to balance, analysing a long document or codebase in one request.
Palmyra X5 is Writer's most advanced model, purpose-built for building and scaling AI agents across the enterprise. It delivers industry-leading speed and efficiency on context windows up to 1 million...
