o4 Mini High example: reading an image into JSON
The example is picked from this model's own capabilities. Drop in your key and it runs as is.
# tip: a data URI works too — base64 the file and prefix it with data:image/jpeg;base64,

o4 Mini High comes from OpenAI; in uttapen you reach it with the model id "openai/o4-mini-high". 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 278 and dearer than 128 of the other paid models in the catalogue.
What you get on top of text in, text out: 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; 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.
Input runs at 319,138 toman per 1M tokens and output at 1,276,550 — output costs 4× input, so trimming the answer saves more than trimming the prompt. 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 Gemini 3.5 Flash (batch): o4 Mini High 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 48 thousand-word requests on o4 Mini High, and every 1,000 toman is about 482 words of round trip. A job with one million input tokens and one million output tokens comes to 1,595,688 toman in total. Filling this model's 200,000-token window costs 63,828 toman on the input side alone, which is the real reason to keep conversation history short.
Its nearest relative in the catalogue is "openai/o4-mini", and choosing between those two is where most people hesitate. Both land at nearly the same price on a thousand-word request (2,074 and 2,074 toman). On parameters, this one takes reasoning_effort.
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. Among the less common parameters it accepts reasoning_effort — all through the standard request body. 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.
Where it makes sense: product chatbots and internal assistants, where cost and quality have to balance, logic puzzles and code review, 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.
OpenAI o4-mini-high is the same model as [o4-mini](/openai/o4-mini) with reasoning_effort set to high. OpenAI o4-mini is a compact reasoning model in the o-series, optimized for fast, cost-efficient performance while retaining...
