Unlock the Power of GPT-5.4: A Comprehensive Guide

The landscape of AI is constantly evolving, and OpenAI has once again pushed the boundaries with the release of GPT-5.4. This new iteration brings significant advancements over its predecessors, including GPT-5.3 Instant and the highly anticipated GPT-5.4 Thinking and GPT-5.4 Pro models. This article will guide you through the key features and practical applications of GPT-5.4, enabling you to leverage its enhanced capabilities for knowledge work, coding, and more.

What You Will Learn

• Understand the new GPT-5.4 models: Thinking, Pro, and Instant.
• Explore significant improvements in knowledge work, including document and spreadsheet generation.
• Discover the power of native computer use capabilities for web-based tasks.
• Evaluate GPT-5.4’s coding performance and its comparison to previous models.
• Test its effectiveness in generating content like presentations and spreadsheets.
• Analyze its performance in writing tasks and its limitations.

Prerequisites

• Access to a ChatGPT account (paid versions like Plus or Pro may be required for full access to the latest models).
• Basic understanding of AI concepts and prompt engineering.

Understanding the New GPT-5.4 Models

OpenAI has rolled out several new models, each designed for specific use cases:

• GPT-5.3 Instant: Released shortly before GPT-5.4, this model provides immediate responses.
• GPT-5.4 Thinking: The focus of this guide, this model performs more in-depth analysis and provides more considered responses. It addresses tasks that require deeper processing.
• GPT-5.4 Pro: Aimed at high-end research, this model offers cutting-edge capabilities for intensive research tasks.

It’s worth noting that the numbering can be a bit confusing, as the ‘Instant’ model (5.3) was released just before the ‘Thinking’ model (5.4). OpenAI has acknowledged this potential for confusion in their documentation.

Key Highlights and Improvements in GPT-5.4

1. Enhanced Knowledge Work Capabilities

GPT-5.4 shows a substantial leap in handling knowledge-based tasks, significantly improving upon GPT-5.2’s abilities. This includes:

• Spreadsheet Generation: Create elaborate and well-formatted spreadsheets with formulas and data charts.
• Document Creation: Generate nicely formatted documents for various purposes.
• Presentation Design: Produce presentations, akin to PowerPoint, complete with sections, citations, and design elements.

Tip: For complex tasks, consider adjusting the ‘thinking effort’ setting within ChatGPT. Options range from ‘Standard’ to ‘Heavy’, though ‘Heavy’ may increase processing time.

2. Native Computer Use

GPT-5.4 is the first general-purpose model with native capabilities for computer use. This means it can perform actions on the web directly, without needing separate agent models. Examples include:

• Data entry
• Handling emails and calendars

This integration streamlines workflows by allowing the AI to interact with digital tools autonomously.

3. Improved Coding Performance

While OpenAI previously released GPT-5.3 CodeX specifically for coding, the general-purpose GPT-5.4 Thinking model now matches its quality and capabilities. This is particularly beneficial for:

• Vibe Coding: The efficient tool-use and search mechanisms in GPT-5.4 make it more token-efficient, potentially lowering costs compared to GPT-5.2 for tasks like tool calling.
• Developer Tooling: Building applications with GPT-5.4 is now more streamlined.

Expert Note: Although GPT-5.4 performs exceptionally well in benchmarks, some users find other models like Claude 4.6 or Gemini 3.1 Pro to be competitive or superior in specific coding scenarios.

4. Reduced Hallucinations

OpenAI claims a further 33% reduction in hallucinations compared to GPT-5.2. While AI models continue to struggle with making up information, each release brings them closer to more reliable outputs. This improvement is crucial for applications where accuracy is paramount.

Testing GPT-5.4 in Action

Step 1: Performing Research Analysis

Let’s test the research capabilities of GPT-5.4 Thinking. We’ll prompt it to analyze the reduction of hallucinations in consumer AI products over time, requesting 10 sources, a plan, findings with citations, and a final checklist.

1. Open your ChatGPT interface and select the GPT-5.4 Thinking model.
2. Enter your research prompt, for example: “Perform a research analysis on whether consumer AI products have reduced hallucinations over time. Provide a three-section output: an upfront plan, findings with citations, and a final checklist. Initially, provide 10 sources.”
3. Observe the model’s response. You can also provide follow-up prompts during the research process, such as requesting more sources (e.g., “Actually, give me 15 sources”), without interrupting the ongoing task.

Result: The model generated a comprehensive analysis, often within a minute or two. It successfully followed the requested structure and provided citations. The ability to issue follow-up prompts mid-task is a significant workflow improvement.

Step 2: Creating a Presentation

Leveraging the research findings, we’ll ask GPT-5.4 to create a presentation.

1. Following the research analysis, prompt the model: “Create a 15-slide PowerPoint presentation based on the research findings, including references to the sources used.”
2. Wait for the model to generate the presentation. This may take several minutes.
3. Once generated, review the presentation. You can also request design changes: “Keep all the information but redesign the presentation in a more modern style.”

Result: GPT-5.4 produced a downloadable presentation with the requested number of slides and content derived from the research. While the initial design might be basic, follow-up prompts can refine the aesthetics.

Step 3: Generating an Excel Spreadsheet

Now, let’s test its spreadsheet generation capabilities.

1. Prompt the model with specific details for your spreadsheet. For instance: “Create an Excel spreadsheet comparing the features, pricing, and user reviews of the top 5 AI writing assistants. Include columns for Feature Set, Monthly Cost, Annual Cost, and Average User Rating.”
2. Allow the model time to generate the spreadsheet, which can take around 10 minutes.
3. Download and open the generated Excel file. Review the data, formulas, and charts.

Warning: Always perform a spot check on numerical data and formulas generated by AI, as hallucinations can still occur, especially with complex calculations.

Result: The output was a downloadable Excel document with multiple pages, formulas, and data charts. This can be a massive time-saver for data organization and analysis.

Step 4: Testing Coding Capabilities

We will test GPT-5.4’s ability to generate a functional web application.

1. Provide a detailed prompt for the website you want to create. Example: “Create a website that compares top AI tools, similar to Futuripedia. Include features like rounded cards, a dark/light mode toggle, and filtering options for different tool categories.”
2. Let the model generate the code. You can often run this directly within ChatGPT’s canvas mode.
3. Review the generated application for functionality and adherence to your prompt.

Result: The model generated a functional app with features like light/dark mode and filtering. While some minor issues might persist (like non-working links or selection issues), the output is often a solid starting point that requires minimal fixes. Compared to GPT-5.2, the performance is noticeably improved.

Step 5: Evaluating Writing Tasks

Let’s assess GPT-5.4’s performance in generating creative writing, such as hooks for a YouTube video.

1. Use a prompt similar to one used for previous models to compare results: “Generate five different hooks for a YouTube video announcing the release of GPT-5.4.”
2. Analyze the output for tone, style, and adherence to any specific instructions (like avoiding certain punctuation).

Observation: In initial tests, GPT-5.4 sometimes struggled to adhere to stylistic instructions, such as avoiding specific punctuation (like ‘m-dashes’), even when system instructions were provided. While it can be guided with follow-up prompts, models like Gemini and Claude may offer a more straightforward, conversational tone out-of-the-box without extensive fine-tuning.

Conclusion

GPT-5.4 represents a significant advancement in AI capabilities, particularly in knowledge work, document generation, and native computer interaction. While it excels in many areas, especially compared to previous versions, users may find other models more adept at specific writing styles without additional prompting. Continued testing and exploration will reveal the full potential of this powerful new iteration.
