On March 5, 2026, OpenAI released GPT-5.4 — a new generation of AI models that takes a significant leap beyond its predecessors. The headline feature is something that sounds straight out of science fiction: the ability to actually use a computer, just like a human would.
What is GPT-5.4?
GPT-5.4 is OpenAI's latest family of AI models, available in four variants to suit different needs:
- GPT-5.4 — the standard model for everyday use
- GPT-5.4 Pro — the most capable version, for complex tasks
- GPT-5.4 mini and nano — smaller, faster, and cheaper for high-volume applications
The big new feature: computer use
The most talked-about capability in GPT-5.4 is computer use — the model can now navigate software, click buttons, fill in forms, and complete workflows across different applications, without any human intervention.
To put this in perspective: you could describe a task to GPT-5.4 (for example, "find all invoices from last month and add them to a spreadsheet"), and the model would open the applications, navigate through them, and complete the task on its own.
On the OSWorld benchmark, which tests how well AI can operate a computer, GPT-5.4 scored 75% — surpassing the human baseline of 72.4%. Its predecessor, GPT-5.2, only managed 47.3%.
Smarter reasoning, fewer wasted words
GPT-5.4 is also significantly more token-efficient than previous models. In simple terms: it thinks more concisely. It reaches correct answers using fewer internal steps, which translates to faster responses and lower costs.
This improvement is especially noticeable for complex reasoning tasks — the kind where earlier models would "ramble" internally before arriving at a conclusion.
What it can handle
Beyond computer use, GPT-5.4 brings improvements across the board:
- Coding: 74.9% pass rate on SWE-bench Verified (compared to ~30% for GPT-4o), making it one of the best AI coding assistants available
- Spreadsheets: 87.3% mean score on spreadsheet tasks, up from 68.4% with GPT-5.2
- Knowledge work: 83% on GDPval, a benchmark testing professional-level tasks
- Factual accuracy: 33% fewer factual errors compared to GPT-5.2
A 1 million token context window
GPT-5.4 supports up to 1 million tokens of context — meaning it can process enormous amounts of information in a single session. Entire codebases, lengthy legal documents, or long research reports can all be analyzed at once.
For comparison, earlier models maxed out at around 128,000 tokens. The jump to 1 million opens up entirely new categories of tasks.
How does it compare to other models?
GPT-4o remains a beloved model for its natural, conversational tone. GPT-5.4, however, outperforms it — and most other models — across nearly every technical benchmark:
| Model | Coding (SWE-bench) | Computer use (OSWorld) | Spreadsheets | Knowledge work (GDPval) |
|---|---|---|---|---|
| GPT-4o | ~33% | — | — | — |
| Claude 3.7 Sonnet | 62.3% | — | — | — |
| GPT-5.2 | — | 47.3% | 68.4% | — |
| GPT-5.4 | 74.9% | 75.0% | 87.3% | 83% |
If you use AI mainly for chat, GPT-4o still feels very natural. But for productivity, automation, or complex problem-solving, GPT-5.4 is in a different league.
What this means in practice
The combination of computer use, a massive context window, and improved accuracy starts to paint a picture of AI that can genuinely act as a capable assistant — not just answering questions, but completing entire workflows.
A few examples of what becomes possible:
- Automatically processing and categorizing emails or documents
- Running multi-step research tasks across multiple web pages
- Writing and testing code end-to-end without manual steps
- Managing repetitive spreadsheet or data entry work
Wrapping up
GPT-5.4 is more than an incremental update — it's a shift in what AI can be used for. The ability to interact with software directly, combined with stronger reasoning and a far larger context window, makes it one of the most capable AI tools available today.
