Palmyra X5 example: rewriting tone

The example is picked from this model's own capabilities. Drop in your key and it runs as is.

from openai import OpenAI

client = OpenAI(base_url="https://api.uttapen.ir/v1", api_key="sk-up-…")

stream = client.chat.completions.create(
    model="writer/palmyra-x5",
    messages=[{"role": "user", "content": "Rewrite this support reply politely: \"That's your problem, just try again.\""}],
    stream=True,
)
for chunk in stream:
    print(chunk.choices[0].delta.content or "", end="", flush=True)
import OpenAI from "openai";

const client = new OpenAI({ baseURL: "https://api.uttapen.ir/v1", apiKey: "sk-up-…" });

const stream = await client.chat.completions.create({
  model: "writer/palmyra-x5",
  messages: [{ role: "user", content: "Rewrite this support reply politely: \"That's your problem, just try again.\"" }],
  stream: true,
});
for await (const chunk of stream) process.stdout.write(chunk.choices[0]?.delta?.content ?? "");

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 92 and dearer than 291 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 207,732 toman per 1M input tokens and 2,077,316 per 1M output tokens. A 1,000-word round trip on Palmyra X5 lands near 2,971 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 about 9% 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 34 thousand-word requests on Palmyra X5, and every 1,000 toman is about 337 words of round trip. A job with one million input tokens and one million output tokens comes to 2,285,048 toman in total. Filling this model's 1,040,000-token window costs 216,041 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.
