Who is GPT-5.4 for?

Programmers and developers

The model is designed for professionals who need a powerful tool for writing and debugging code. GPT-5.4 handles complex programming tasks, supports function calling, and generates structured code.

Documentation specialists

Thanks to its 1-million-token context, the model is well suited for analyzing and processing large documents, reports, legal texts, and technical texts.

Image analysts

The ability to process full-resolution images makes GPT-5.4 useful for those who work with visual data, from analyzing charts and tables to recognizing details in images.

How to use GPT-5.4?

Through the OpenAI API

The model is available directly through the OpenAI API. To use it, you need to sign up and get access to a paid subscription. The API documentation describes all integration methods, including configuring function calls and generating structured data.

Core Features of GPT-5.4

Multimodality and image processing

GPT-5.4 processes text and full-resolution images. This allows the model to be used for tasks where detailed visual analysis is important, such as recognizing complex diagrams or reading text from photos.

Context of up to 1 million tokens

One of the model's key parameters is its ability to hold up to 1 million tokens in context. This makes it suitable for processing entire books, large codebases, or long conversations without losing information.

Long-term reasoning and tool search

The model supports improved long-term logical reasoning mechanisms that enable it to solve multi-step tasks. It also includes tool search (Tool Use), Function Calling, Code Execution, Web Search, Batch Inference, and Fine-tuning.

Advantages of GPT-5.4

Strong benchmark performance

The model achieves high scores on tests: GPQA — 93%, ARC-AGI — 94%, Tau2 Telecom — 99%. This confirms its ability to handle complex tasks in reasoning, computer vision, and telecommunications.

Huge context window

A context of 1 million tokens is one of the model's main advantages. It allows you to work with large amounts of data without having to split requests into multiple parts.

Wide range of tools

GPT-5.4 includes many built-in capabilities, from function calling and structured data generation to batch processing and fine-tuning. This makes the model a versatile solution for professional tasks.

Limitations of GPT-5.4

Paid access model

GPT-5.4 is available exclusively through a paid subscription. There is no free access to the model, which may be a limitation for users with a small budget or those who are just getting familiar with neural network capabilities.

Proprietary license

The model uses a proprietary license. This means the source code, architecture, and weights are not available for independent study, modification, or local deployment. Users fully depend on OpenAI's infrastructure.

Output token limit

The maximum response length is 128,000 tokens. For very large tasks that require generating extremely long texts or code, the request may need to be split into several parts.

What Tasks Does GPT-5.4 Solve?

Professional programming

The model is designed for writing, refactoring, and debugging code. It supports function calling, structured data generation, and code execution, which is useful for developers of any level.

Image processing and analysis

GPT-5.4 can analyze full-resolution images. This is suitable for recognition tasks, describing visual content, extracting text from images, and working with graphical data.

Long-term reasoning and multi-step tasks

Thanks to improved long-term reasoning, the model handles tasks that require logical chains, planning, and the sequential solution of complex problems.

Batch processing, web search, and function calling

The model supports batch processing of requests, built-in web search, and external function calls. This makes it possible to automate routine processes and integrate the neural network into existing workflows.

GPT-5.4 Pricing

The cost of using the model is calculated based on the number of processed tokens. Input tokens (data sent to the model) are priced at $2.50 per 1 million tokens. Output tokens (model responses) cost $15.00 per 1 million tokens. This pricing is typical for professional OpenAI models and is aimed at users who need high performance and a large context.

Terms of Use for GPT-5.4

The model is available through the OpenAI API. A paid subscription and access to OpenAI's infrastructure are required. Terms of use follow OpenAI's general policy for proprietary models.

Availability of GPT-5.4

GPT-5.4 is available through the OpenAI API (web platform).

How Does GPT-5.4 Differ from Alternatives?

GPT-5.4 is part of the GPT-5 family from OpenAI. The comparison page contains links to other models in this lineup: GPT-5.5, GPT-5.1 High, GPT-5 High, GPT-5.1 Thinking, GPT-5.2, GPT-5 Medium, GPT-5.1 Medium, GPT-5.1 Instant, and GPT-5.4 mini. The direct differences between GPT-5.4 and the listed alternatives are not described in the source data. It can be assumed that the key parameters distinguishing models within the family are context size, token pricing, benchmark performance, and available features; however, exact differences require additional review of OpenAI documentation.

Conclusion

GPT-5.4 is a powerful multimodal model from OpenAI aimed at professional users. It supports a context of up to 1 million tokens, full-resolution image processing, function calling, and long-term reasoning. The model is available through a paid subscription via the API. High benchmark scores and a wide range of tools make it a suitable choice for programmers, analysts, and anyone working with large amounts of data and complex tasks.
