What is Aion-3.0-Mini good for?

Aion-3.0-Mini is one of Aion Labs's models. Put "aion-labs/aion-3.0-mini" in the model field and the rest of your code stays as it is. Aion-3.0-Mini keeps 131,072 tokens in view at once, and that number is what caps the conversation history in your product. A single response can run to 32,768 tokens. On price it sits in the "cheap" band — cheaper than 221 and dearer than 174 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 242,354 toman per 1M input tokens and 484,707 per 1M output tokens. A 1,000-word round trip on Aion-3.0-Mini lands near 945 toman. It supports cached input: repeated context is billed at 62,319 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 GLM 5.3: Aion-3.0-Mini works out about 40% 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 106 thousand-word requests on Aion-3.0-Mini, and every 1,000 toman is about 1,058 words of round trip. A job with one million input tokens and one million output tokens comes to 727,061 toman in total. Filling this model's 131,072-token window costs 31,766 toman on the input side alone, which is the real reason to keep conversation history short.

Its nearest relative in the catalogue is "aion-labs/aion-2.0", and choosing between those two is where most people hesitate. Both land at nearly the same price on a thousand-word request (945 and 1,080 toman).

Aion Labs has 6 models in our catalogue; the cheapest is Aion-3.0-Mini at 945 toman per thousand words and the dearest Aion 3.5 at 4,051. 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 Nano Banana Pro (Gemini 3 Pro Image) at 131,072 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.
