OpenAI is expanding its AI portfolio with ChatGPT-5.4, targeting users who use AI for complex tasks, software development or large documents. The new version builds on previous models and brings improvements in analysis, planning and automation. The new thinking model in particular is designed to work in a more structured way and make the thinking process more transparent. At the same time, OpenAI is introducing a more powerful Pro version, which has been optimized primarily for demanding professional workflows.
- ChatGPT 5.4 Thinking with a transparent planning and thinking process for complex tasks
- Improved research and analysis functions without losing context in conversations
- Optimized for programming, documents, presentations and spreadsheets
- Rollout for Plus, Team, Pro and Enterprise, free users not initially included
ChatGPT-5.4 Thinking: Structured AI workflow for complex tasks
With ChatGPT-5.4 Thinking, OpenAI is focusing on an approach that structures AI responses more strongly. Instead of directly outputting a final answer, the model first starts with a planning or thinking process that describes the planned solution path. This allows work steps to be adapted before the AI works out a final solution.
This approach is particularly suitable for scenarios in which several steps are necessary – for example, when analyzing large data sets, planning software projects or conducting extensive research. According to OpenAI, the handling of deep web research has been significantly improved. The model can integrate new information without losing the context of previous parts of the conversation.
ChatGPT-5.4 should also be significantly stronger for productive tasks. According to the manufacturer, the model shows noticeable progress, especially when creating tables, presentations or documents. Internal tests show an increase in performance compared to previous versions: While earlier models achieved around 68.4% in certain benchmark tests, ChatGPT-5.4 is said to achieve around 87.3%.
Another focus is on interaction with computer systems. The model can generate code that controls applications via automation libraries. These include, for example:
- Control of programs via mouse and keyboard input
- Automated workflows based on screenshots
- Creation of scripts for tools such as Playwright
This means that AI is moving more towards automated software agents that can perform real tasks on a computer.
ChatGPT-5.4 Pro: More power for professional AI applications
In addition to the Thinking version, OpenAI is also introducing ChatGPT-5.4 Pro. This version is intended for particularly demanding applications and is primarily aimed at companies or professional users who require maximum performance.
The Pro version is intended to offer particular advantages for complex calculations, extensive data analysis or large code projects. Thanks to additional computing resources, the model can process larger tasks and work more stably at the same time. The new model could play a particularly important role in areas such as software development, data analysis or content production.
OpenAI is thus clearly positioning ChatGPT-5.4 as a professional AI tool rather than a pure chatbot. Especially in combination with automation and software integration, the new version could become an important part of modern working environments.
The rollout will start gradually. ChatGPT-5.4 Thinking is initially available for Plus, Team and Pro subscribers. The more powerful Pro version will initially be reserved for Pro and Enterprise users. Access for free accounts is currently not planned.
Conclusion
With ChatGPT-5.4, OpenAI is expanding its AI platform with a model that is more strongly geared towards professional applications. The new thinking approach ensures comprehensible solutions, while the Pro version offers additional performance for complex tasks. Computer control and automation functions in particular could create new application possibilities in the long term. ChatGPT-5.4 is already being rolled out in stages and is initially available to paying users.
