}'What is o3 Mini (batch) good for?
o3 Mini (batch) comes from OpenAI; in uttapen you reach it with the model id "openai/o3-mini:batch". It accepts up to 200,000 tokens of input per call, so a long document or several source files fit in a single request. A single response can run to 100,000 tokens. On price it sits in the "mid-range" band — cheaper than 215 and dearer than 191 of the other paid models in the catalogue.
What it can do beyond plain text: 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; 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 159,569 toman per 1M input tokens and 638,275 per 1M output tokens. A 1,000-word round trip on o3 Mini (batch) lands near 1,037 toman. It supports cached input: repeated context is billed at 79,784 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 MiniMax M1: o3 Mini (batch) works out roughly 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 96 thousand-word requests on o3 Mini (batch), and every 1,000 toman is about 964 words of round trip. A job with one million input tokens and one million output tokens comes to 797,844 toman in total. Filling this model's 200,000-token window costs 31,914 toman on the input side alone, which is the real reason to keep conversation history short.
This id gets confused with "openai/o3-mini", because the underlying model is the same. The difference is the suffix: "batch" against the standard variant. On a thousand-word request this variant works out 2× cheaper (1,037 against 2,074 toman).
OpenAI has 95 models in our catalogue; the cheapest is gpt-oss-20b at 60 toman per thousand words and the dearest o1-pro at 282,872. It does not support temperature, top_p, 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 Claude 3 Haiku at 200,000 tokens.
Good fits: product chatbots and internal assistants, where cost and quality have to balance, 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.
OpenAI o3-mini is a cost-efficient language model optimized for STEM reasoning tasks, particularly excelling in science, mathematics, and coding. This model supports the `reasoning_effort` parameter, which can be set to...
