}'What is Magnum v4 72B good for?
The id for Magnum v4 72B in our API is "anthracite-org/magnum-v4-72b", served from Anthracite Org. Context is 32,768 tokens; past that you have to summarise the history yourself. A single response can run to 4,096 tokens. On price it sits in the "mid-range" band — cheaper than 287 and dearer than 119 of the other paid models in the catalogue.
What it can do beyond plain text: it returns schema-valid JSON through response_format, ready to hand to your code. All of it works through the standard parameters of the official OpenAI SDK — no custom client, no wrapper.
Pricing is 725,313 toman per 1M input tokens and 1,450,625 per 1M output tokens. A 1,000-word round trip on Magnum v4 72B lands near 2,829 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 Palmyra X5: Magnum v4 72B works out roughly 1.1× more expensive, and its context window is smaller. 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 35 thousand-word requests on Magnum v4 72B, and every 1,000 toman is about 353 words of round trip. A job with one million input tokens and one million output tokens comes to 2,175,938 toman in total. Filling this model's 32,768-token window costs 23,767 toman on the input side alone, which is the real reason to keep conversation history short.
Among the less common parameters it accepts logit_bias, logprobs, min_p, repetition_penalty, top_a, top_k — all through the standard request body. It does not support include_reasoning, reasoning, tool_choice, tools, 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 Aion-RP 1.0 (8B) at 32,768 tokens.
Good fits: product chatbots and internal assistants, where cost and quality have to balance, extracting data against a fixed schema.
This is a series of models designed to replicate the prose quality of the Claude 3 models, specifically Sonnet(https://openrouter.ai/anthropic/claude-3.5-sonnet) and Opus(https://openrouter.ai/anthropic/claude-3-opus). The model is fine-tuned on top of [Qwen2.5 72B](https://openrouter.ai/qwen/qwen-2.5-72b-instruct).
