GPT-5.4 Pro (batch) 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.

GPT-5.4 Pro (batch) is one of OpenAI's models. Put "openai/gpt-5.4-pro:batch" in the model field and the rest of your code stays as it is. GPT-5.4 Pro (batch) keeps 1,050,000 tokens in view at once, and that number is what caps the conversation history in your product. A single response can run to 128,000 tokens. On price it sits in the "expensive" band — cheaper than 399 and dearer than 7 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; 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 4,351,875 toman per 1M input tokens and 26,111,250 per 1M output tokens. A 1,000-word round trip on GPT-5.4 Pro (batch) lands near 39,602 toman. 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 Claude Opus 4: GPT-5.4 Pro (batch) works out roughly 1.2× more expensive, and its context window is larger. 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 3 thousand-word requests on GPT-5.4 Pro (batch), and every 1,000 toman is about 25 words of round trip. A job with one million input tokens and one million output tokens comes to 30,463,125 toman in total. Filling this model's 1,050,000-token window costs 4,569,469 toman on the input side alone, which is the real reason to keep conversation history short.
This id gets confused with "openai/gpt-5.4-pro", 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 (39,602 against 79,204 toman). On parameters the other takes max_completion_tokens.
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 MiMo-V2.5 at 1,050,000 tokens.
Good fits: work where the quality of the answer matters more than its cost, 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.
GPT-5.4 Pro is OpenAI's most advanced model, building on GPT-5.4's unified architecture with enhanced reasoning capabilities for complex, high-stakes tasks. It features a 1M+ token context window (922K input, 128K...

Frequently asked
- How do I call GPT-5.4 Pro (batch) from Iran?
- Sign up with your mobile number, top the wallet up in toman, create an API key, then in the official OpenAI SDK point base_url at https://api.uttapen.ir/v1 and set model to "openai/gpt-5.4-pro:batch". Nothing else in your code changes.
- What does GPT-5.4 Pro (batch) cost in toman?
- 4,351,875 toman per 1M input tokens and 26,111,250 toman per 1M output tokens; a 1,000-word request is around 39,602 toman. You pay for the usage that request actually reported, and a failed request costs nothing.
- How much input does GPT-5.4 Pro (batch) take?
- Up to 1,050,000 tokens per request, roughly 788k words. A single answer can reach 128,000 tokens.
- Does GPT-5.4 Pro (batch) support streaming and tool calling?
- Streaming (stream=true) works on every model here. This one supports tool calling in the standard OpenAI shape. Image input is accepted through image_url, as a data URI or a public URL. Structured output through response_format works too.
