GPT-5.4 (batch) example: reading an image into JSON

What is GPT-5.4 (batch) good for?

OpenAI publishes this model; we expose it under the id "openai/gpt-5.4:batch". Its context window is 1,050,000 tokens, roughly 788k English words in one request. A single response can run to 128,000 tokens. On price it sits in the "mid-range" band — cheaper than 313 and dearer than 93 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 362,656 toman per 1M input tokens and 2,175,938 per 1M output tokens. A 1,000-word round trip on GPT-5.4 (batch) lands near 3,300 toman. It supports cached input: repeated context is billed at 36,266 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 Claude Sonnet 4.5 (batch): GPT-5.4 (batch) works out roughly 1× cheaper, 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 30 thousand-word requests on GPT-5.4 (batch), and every 1,000 toman is about 303 words of round trip. A job with one million input tokens and one million output tokens comes to 2,538,594 toman in total. Filling this model's 1,050,000-token window costs 380,789 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", 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 (3,300 against 6,600 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: 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.

Frequently asked

How do I call GPT-5.4 (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:batch". Nothing else in your code changes.
What does GPT-5.4 (batch) cost in toman?
362,656 toman per 1M input tokens and 2,175,938 toman per 1M output tokens; a 1,000-word request is around 3,300 toman. You pay for the usage that request actually reported, and a failed request costs nothing.
How much input does GPT-5.4 (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 (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.
