OpenAI continues to develop artificial intelligence at a rapid pace. The latest model, GPT-5.4, is a major update to ChatGPT, focusing on improved reasoning, integration with work tools and the ability to automate tasks across different applications.
The new model is designed to help users with more advanced tasks — from programming and analysis to document work and data management.
In this article, we cover what GPT-5.4 is, what new features it includes and how it differs from previous models.
What is GPT-5.4?
GPT-5.4 is an updated version of OpenAI's language model that powers ChatGPT. It builds on previous generations but introduces several improvements in:
- Advanced reasoning
- Handling large datasets
- Integration with other applications
- Automated workflows
The goal of the model is to make AI a more powerful tool for work, analysis and productivity.
Thinking Mode – better AI reasoning
One of the biggest innovations in GPT-5.4 is Thinking Mode.
This mode allows the model to analyse a problem more systematically before providing an answer. The result is often more accurate and well-considered responses, especially for complex tasks.
Thinking Mode is particularly useful for:
- Programming
- Mathematics
- Logical problems
- Advanced analysis
For developers and analysts, this means AI can function more as a problem solver than a regular chatbot.
Integration with Excel and Google Sheets
GPT-5.4 also features improved integration with spreadsheet tools such as Microsoft Excel and Google Sheets.
This allows AI to assist with:
- Data analysis
- Formula creation
- Automated reports
- Data visualisation
These types of features make the model particularly attractive for businesses that work extensively with data.
Up to 1 million tokens of context
Another major improvement is the increased context capacity.
GPT-5.4 can handle up to 1 million tokens, meaning the model can read and analyse much larger documents than before.
This makes it possible to:
- Analyse lengthy reports
- Process large datasets
- Work with entire projects in the same conversation
The larger context also means AI can better keep track of context in long workflows.
AI agents and automated tasks
GPT-5.4 is a step towards what is often called AI agents.
This means AI doesn't just answer questions but can also:
- Use applications
- Perform tasks in programs
- Automate workflows
In practice, AI can help with everything from analysing data to creating documents or code in other tools.
GPT-5.4 vs previous models
Here are some of the most important differences between GPT-5.4 and previous models:
| Feature | GPT-4 | GPT-5.4 |
|---|---|---|
| Reasoning | Good | Significantly better |
| Context | Smaller | Up to 1M tokens |
| Integrations | Limited | Excel, Sheets etc. |
| Automation | Basic | AI agents |
The result is an AI model better suited for professional work and complex tasks.
How GPT-5.4 can be used
The new model can be used across many areas, for example:
Programming
- Writing and analysing code
- Debugging programs
Data analysis
- Analysing large datasets
- Creating reports and dashboards
Content creation
- Writing articles
- Creating marketing copy
Business work
- Document management
- Automated workflows
Summary
GPT-5.4 is a major step forward for artificial intelligence. With better reasoning, larger context and integration with work tools, the model becomes more useful in both everyday life and work.
The key improvements are:
- Thinking Mode for better problem solving
- Integration with Excel and Google Sheets
- Up to 1 million tokens of context
- Support for AI agents and automated workflows
The development clearly shows that AI is moving from simple chatbots to powerful digital work assistants.
Frequently asked questions about GPT-5.4
How much does GPT-5.4 cost? GPT-5.4 is available through ChatGPT Plus and Enterprise plans. The pricing model varies depending on usage and which plan you choose.
Can I use GPT-5.4 for free? Basic features are available in the free version of ChatGPT, but the most advanced features like Thinking Mode and extended context require a paid plan.
Is GPT-5.4 better than Claude? It depends on the use case. GPT-5.4 has strong integration capabilities while Claude often excels in reasoning and coding. The choice depends on your specific needs.
Can GPT-5.4 replace an enterprise AI platform? GPT-5.4 is a powerful tool, but lacks features that many businesses need — such as data security with Swedish jurisdiction, RAG with source citations, and integration with internal systems. A dedicated enterprise platform like Noda is better suited for business-critical needs.
How does GPT-5.4 differ from GPT-4? The biggest differences are better reasoning (Thinking Mode), a much larger context window (1M tokens), deeper integrations with work tools and support for AI agents that can perform tasks automatically.
Is GPT-5.4 safe to use for businesses? OpenAI has improved security, but data is sent to servers in the US. Businesses with high requirements for data security and GDPR should consider European alternatives or complement with a platform that handles data within the EU/Sweden.
