GPT-5.4: The "Brain" That Thinks Before It Speaks

The AI world never sleeps, and OpenAI dropped a bombshell with the launch of GPT-5.4. If you thought GPT-5.2 was already fast, this update was not only smarter but changed the rules of the game in how we work.

Update (September 2026): GPT-5.4 has since been replaced by GPT-5.6 (Sol, Terra and Luna) in ChatGPT. This article is kept as a reference for what GPT-5.4 brought; current plans and prices are in how much does ChatGPT cost.

Here's a summary of the top features of this version so you're not caught off guard.

In this article, we tell you what's new and how this version changes your workflow.

💡 Tip from ElGrupito: mastering these tools before anyone else is what makes the difference in today's market. On ElGrupito you can get ChatGPT Plus at a group price.

The 5 Big New Features of GPT-5.4

1. 🧠 Interactive "Thinking": You're in Control!

The most visual novelty of GPT-5.4 Thinking is that the model now shows you an initial plan of what it's going to do.

• The best part: You no longer have to wait for it to finish to realize it made a mistake.
• Real-time interruption: If you see the plan isn't what you were looking for, you can adjust course mid-response. It's like working with an assistant you can correct while they write.

2. 💻 Native Computer Use

This is the "star" feature for the pros. GPT-5.4 can now interact directly with software.

• It can use the mouse and keyboard (virtually) to navigate tabs, fill out complex forms, or manage files across different applications.
• It surpassed human expert levels in digital autonomy tests. It can literally do office tasks for you!

3. 📊 The King of Excel and Finance

OpenAI launched alongside this model the new ChatGPT for Excel. Now you can talk to your spreadsheets in natural language.

• Create financial models from scratch.
• Explain complicated formulas you inherited from someone else.
• It connects directly with data sources like S&P Global and Moody's.

4. 📉 Goodbye to Hallucinations (or Almost)

We know that sometimes AI "makes up" things with a lot of confidence. Well, GPT-5.4 has reduced errors:

• It's 33% less likely to invent false data compared to GPT-5.2.
• Its responses are 18% more accurate in general knowledge tasks.

5. 🏗️ Elephant Memory (1 Million Tokens)

For those who handle massive files, GPT-5.4 launched in the API with a 272K-token context window; today's GPT-5.6 models reach 1,050,000 tokens. This means you can upload entire books, massive programming code, or endless legal contracts, and the AI won't forget what it read on page 1 when it reaches page 1,000.

💡 Fun fact: GPT-5.4 is much more efficient. It uses fewer "tokens" to solve the same problems as previous versions, which translates to faster and cheaper responses for developers.

Don't Get Left Behind

Understanding AI is this decade's superpower. On ElGrupito you can get ChatGPT Plus at a group price and use OpenAI's models without paying for the full plan.

Who Can Use It Now?

• Plus, Team (now Business), and Pro users: Were the first to get GPT-5.4 Thinking (which replaced the old 5.2); today every plan runs GPT-5.6.
• Enterprise users: Had access from launch to the Pro version, which is even more powerful for heavy-duty tasks.

Is It Worth the Switch?

Definitely yes. GPT-5.4 wasn't trying to be "smarter" at impossible math but rather more human and less annoying. It was the update we needed to make using AI feel like a real conversation.

Have you noticed the change in your responses? If you want to use this model and its successors without paying for the full plan, ElGrupito offers ChatGPT Plus at a group price.

FAQs About ChatGPT 5.4 New Features

1. What's the difference between GPT-5.4 and GPT-5.2? The big difference is the reasoning process. While 5.2 gave an instant response, GPT-5.4 (Thinking) takes a few seconds to plan its answer. Additionally, 5.4 includes "Computer Use", allowing it to perform tasks on your desktop that were previously impossible.

Can it really control my computer?

Yes, but under your supervision. OpenAI has implemented this feature securely: the AI asks your permission to perform complex actions and you can see in real time what buttons it's "pressing" or what tabs it's opening.

Is it slower than previous versions?

Surprisingly, no. Although it "thinks" before writing, the text generation speed is superior to GPT-5.2 once it gets going. The reasoning wait time is offset by a much more accurate response on the first try, saving you correction time.

What about my data privacy?

OpenAI maintains its policies: if you use the Business (formerly Team) or Enterprise versions, your data is not used to train the model. If you're a Plus or free user, you can disable training in the privacy settings, so your secrets are safe!

What if OpenAI releases an update tomorrow?

The AI world moves fast: in fact, GPT-5.4 has already been replaced by GPT-5.6. The advantage of a ChatGPT Plus subscription, also available at a group price on ElGrupito, is that you get the new models as soon as OpenAI releases them, without changing plans.
