MiniMax M2.1 example: JSON output against a schema

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

from openai import OpenAI
import json

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

schema = {

What is MiniMax M2.1 good for?

MiniMax M2.1 is one of MiniMax's models. Put "minimax/minimax-m2.1" in the model field and the rest of your code stays as it is. MiniMax M2.1 keeps 204,800 tokens in view at once, and that number is what caps the conversation history in your product. A single response can run to 131,072 tokens. On price it sits in the "cheap" band — cheaper than 232 and dearer than 157 of the other paid models in the catalogue.

What it can do beyond plain text: 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; it has a reasoning mode that pays off on multi-step problems, maths and debugging. All of it works through the standard parameters of the official OpenAI SDK — no custom client, no wrapper. Keep in mind that reasoning tokens are output tokens and do appear on the bill.

Pricing is 103,866 toman per 1M input tokens and 415,463 per 1M output tokens. A 1,000-word round trip on MiniMax M2.1 lands near 675 toman. It supports cached input: repeated context is billed at 10,387 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 LongCat 2.0, and MiniMax M2.1 costs about the same, 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 148 thousand-word requests on MiniMax M2.1, and every 1,000 toman is about 1,481 words of round trip. A job with one million input tokens and one million output tokens comes to 519,329 toman in total. Filling this model's 204,800-token window costs 21,272 toman on the input side alone, which is the real reason to keep conversation history short.

Its nearest relative in the catalogue is "minimax/minimax-m2.7", and choosing between those two is where most people hesitate. Both land at nearly the same price on a thousand-word request (675 and 675 toman). On parameters the other takes frequency_penalty, logit_bias, min_p, presence_penalty.

MiniMax has 9 models in our catalogue; the cheapest is MiniMax M3.1 Flash at 338 toman per thousand words and the dearest MiniMax M1 at 1,238. It does not support seed, structured_outputs, 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 GLM 4.6 at 204,800 tokens.

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