GPT-5.4 Image 2: pricing, context and benchmarks

What you need to know about GPT-5.4 Image 2

OpenAI, based in United States, put GPT-5.4 Image 2 online on April 21, 2026. It accepts images, text, and files as input and produces images and text. Its context window reaches 272,000 tokens, larger than 59 % of the models in the registry, and it can write up to 128,000 tokens in one go.

It has been available for about 6 months, long enough for its prices and scores to have settled.

GPT-5.4 Image 2 pricing

On OpenRouter, GPT-5.4 Image 2 costs $8 per million input tokens and $15 per million output tokens. Counting three tokens read for every token written, its average price is $9.75 per million, more expensive than 93 % of paid models (12.8 times the median of $0.76).

A concrete example: a task that sends 2,000 tokens (about 1,500 words) and receives a 500-token answer costs $0.0235. At 1,000 tasks a day, budget $705 a month. The price calculator redoes this with your own volumes.

Tokens already sent and cached are billed at $2 per million.

Performance and benchmarks

Epoch AI does not yet publish a capabilities index for GPT-5.4 Image 2. We therefore show no made-up performance rating: only price, context and features count towards its score.

Features, privacy and local use

• It does not support tool calling: it is not suited to driving an AI agent that has to act.
• It can answer in an enforced JSON format (structured outputs).
• It is a reasoning model: it "thinks" before answering, which helps on hard tasks but uses more output tokens.

Its weights are not published: it can only be used through the OpenAI API or a broker such as OpenRouter, which means sending your data off your machines.
