Introduction

OpenAI introduced GPT-5.4 as the newest iteration of its large language model, highlighting advances in reasoning, coding, and task automation. The rollout spans ChatGPT, the API, and developer tools, with versions tailored for everyday users and enterprise workloads.

Direct Computer Interaction

One of the most significant changes is the model’s ability to interact directly with computers. GPT-5.4 can interpret screenshots, operate browsers, and issue keyboard and mouse commands, allowing it to complete tasks across multiple applications without human intervention. This capability supports complex, multi‑step workflows that previously disrupted user productivity.

Enhanced Research and Reasoning

The update improves the model’s capacity to conduct multi‑round information gathering, combining findings into clearer, structured answers. OpenAI describes GPT-5.4 as its most factual model to date, noting a reduction in false claims compared with its predecessor.

“Thinking” Mode

GPT-5.4 introduces a “Thinking” mode inside ChatGPT, designed for complex prompts. This mode displays a visible outline of the model’s reasoning, allowing users to adjust instructions mid‑response and guide outcomes without restarting the conversation.

Longer Context and Coding Support

The model retains information across extended workflows, making it especially useful for coding tools such as OpenAI Codex. Developers can rely on GPT-5.4 to automate large or time‑consuming development tasks.

Availability

GPT-5.4 is currently rolling out to ChatGPT users on the web and Android, with iOS support expected soon. OpenAI also offers a Pro version aimed at enterprise and academic customers that need maximum performance for complex workloads.
