What is Mistral Large 3 2512 good for?

Mistral Large 3 2512 is one of Mistral's models. Put "mistralai/mistral-large-2512" in the model field and the rest of your code stays as it is. Mistral Large 3 2512 keeps 262,144 tokens in view at once, and that number is what caps the conversation history in your product. A single response can run to 209,715 tokens. On price it sits in the "cheap" band — cheaper than 173 and dearer than 233 of the other paid models in the catalogue.

What it can do beyond plain text: it reads images directly, which makes it a real option for invoices, forms and screenshots; it takes files such as PDFs as input; it supports tool calling, so it can invoke your own functions with valid arguments; 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 145,063 toman per 1M input tokens and 435,188 per 1M output tokens. A 1,000-word round trip on Mistral Large 3 2512 lands near 754 toman. It supports cached input: repeated context is billed at 14,506 toman per 1M, which matters a lot if your system prompt is long. 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 Gemini 3 Flash Preview (batch): Mistral Large 3 2512 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 133 thousand-word requests on Mistral Large 3 2512, and every 1,000 toman is about 1,326 words of round trip. A job with one million input tokens and one million output tokens comes to 580,250 toman in total. Filling this model's 262,144-token window costs 38,027 toman on the input side alone, which is the real reason to keep conversation history short.

Its nearest relative in the catalogue is "mistralai/mistral-medium-3", and choosing between those two is where most people hesitate. On a thousand-word request this variant works out 1.2× cheaper (754 against 905 toman). The context windows differ too: 262,144 against 131,072 tokens. Maximum answer length differs as well: 209,715 against 104,857 tokens.

Mistral has 20 models in our catalogue; the cheapest is Mistral Nemo at 18 toman per thousand words and the dearest Mistral Medium 3.5 at 3,394. It does not support include_reasoning, reasoning, 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 Trinity Large Thinking at 262,144 tokens.

Good fits: high-volume work such as classification, tagging and bulk summarising, pulling text and fields out of images, agents that reach out to APIs and databases, extracting data against a fixed schema, analysing a long document or codebase in one request.
