Originally published in Turkish. Read the original →
OpenAI has announced ChatGPT-5.4, a model designed for professional workflows and complex tasks. We look at the new features of the Thinking and Pro versions, the benchmark results and a detailed comparison with rival AI models.
ChatGPT-5.4: OpenAI's Professional-Grade AI Takes the Stage
OpenAI has made yet another move without slowing its pace in the AI model race. Officially announced on March 5, 2026, ChatGPT-5.4 is a next-generation AI system the company positions as its "most capable and efficient frontier model for professional work." The model comes in two versions: ChatGPT-5.4 Thinking and ChatGPT-5.4 Pro. So what has this update learned from the recently announced GPT-5.3 Instant and from the previous generation, GPT-5.2? And where does it stand against its rivals?
The Thinking Model: Transparency Into the AI's "Thought Process"
The most notable innovation in ChatGPT-5.4 takes shape in the version called Thinking. Traditional large language models (LLMs) usually work like a "black box" when producing an answer: they take an input and give an output, and the process in between stays invisible to the user. The Thinking model fundamentally changes this paradigm.
In the new model, answers start with an action plan. The model clearly shows the user how it will approach the problem, which steps it will follow and which assumptions it is starting from. This lets users intervene in the model's chain of thought; when they notice it is heading in the wrong direction, they can change course before the answer is finished. This feature is a big advantage especially in fields that require multi-step problem solving, such as software development, data analysis and academic research.
Transparency of the thought process is a critical design decision that strengthens the trust between AI and humans. Instead of asking "is the AI telling me the truth?", users can now follow the model's reasoning step by step.
Computer Use: An AI That Sees and Controls the Screen
One of the most striking technical innovations in ChatGPT-5.4 is the model's ability to interact directly with computers. OpenAI explained that the model can write code that performs computer operations using automation libraries such as Playwright. Beyond that, the model can analyze screenshots to recognize interface elements and generate mouse movements and keyboard commands.
This capability proves itself with concrete numbers on the OSWorld Verified benchmark: GPT-5.4 reached a 75.0% success rate in navigating desktop environments, surpassing human performance (72.4%). Considering GPT-5.2's score of 47.3% on the same test, the size of the progress made in a single generation is striking.
The Story Behind the Benchmark Results
The official data shared by OpenAI shows that ChatGPT-5.4 made serious leaps over its predecessor in almost every area:
- Professional Knowledge Work (GDPval): In a comparison across 44 different occupations, GPT-5.4 raised its rate of matching or beating human professionals to 83.0% (GPT-5.2: 70.9%).
- Spreadsheet Modeling: On investment-banking-style financial modeling tasks, the success rate rose from GPT-5.2's 68.4% to 87.3%.
- Abstract Reasoning (ARC-AGI-2): GPT-5.4 Pro achieved a remarkable score of 83.3% on this test; GPT-5.2 Pro had scored 54.2%.
- Web Research (BrowseComp): In the ability to search for and synthesize information, GPT-5.4 reached 82.7%, while GPT-5.4 Pro recorded an impressive 89.3% (GPT-5.2: 65.8%).
- Coding (SWE-Bench Pro): A modest but consistent increase to 57.7% (GPT-5.3 Codex: 56.8%, GPT-5.2: 55.6%).
- Hallucination Reduction: Individual claims contain 33% fewer errors compared with GPT-5.2, while the error rate in full responses was reduced by 18%.
Token Efficiency and a 1 Million Token Context
OpenAI describes GPT-5.4 as its "most token-efficient reasoning model yet." The model consumes significantly fewer tokens than previous versions for the same tasks. This means a serious cost advantage, especially for enterprise customers who use the API heavily.
The context window has also been expanded to 1 million tokens. This capacity lets the model work without losing context on tasks such as analyzing huge codebases, reviewing long legal documents or synthesizing comprehensive research reports. The newly added "Tool Search" API feature, which loads tool definitions only when they are needed, reduced token consumption by 47% in tests.
A Note on Cybersecurity
Another notable development is that GPT-5.4's cybersecurity rating has risen to the "High Capability" level, a first for a general-purpose model. This is official confirmation that the model has matured enough to make professional-level contributions in areas such as vulnerability analysis, threat modeling and defense automation.
Comparison With Rivals: The AI Landscape in March 2026
To understand where ChatGPT-5.4 stands in the industry, it is important to look at a comparison table with its current rivals:
| Feature | GPT-5.4 Thinking/Pro | Claude Opus 4.6 | Gemini 3.1 Pro | Grok 4.1 |
|---|---|---|---|---|
| Developer | OpenAI | Anthropic | Google DeepMind | xAI |
| Context Window | 1M tokens | 1M tokens | 1M tokens | 256K tokens |
| ARC-AGI-2 (Abstract Reasoning) | 83.3% (Pro) | 68.8% | 77.1% | No data |
| GDPval (Professional Work) | 83.0% | Elo: 1,606 (leader) | — | — |
| SWE-Bench (Coding) | 57.7% | 80.8% (Verified) | — | — |
| OSWorld (Computer Use) | 75.0% | — | — | — |
| BrowseComp (Web Research) | 89.3% (Pro) | — | — | Real-time X data |
| Hallucination Reduction | 33% fewer errors | — | — | — |
| Computer Use | ✅ Native | ✅ (Computer Use API) | ❌ | ❌ |

| Target Audience | Professionals, enterprise | Developers, enterprise | Researchers, general use | Social-media-focused users |
This table reveals a few important trends. GPT-5.4 is the strongest model in professional knowledge work and computer use. Claude Opus 4.6 stands out in coding and autonomous agent systems; it leads by a wide margin on SWE-Bench Verified with 80.8%. Gemini 3.1 Pro looks unmatched in pure reasoning and multimodal capabilities (image, video, audio). Grok 4.1, with its X (formerly Twitter) integration, offers a niche advantage in real-time information access.
Access and Subscription Structure
The rollout of ChatGPT-5.4 began gradually on March 5. The access plan is as follows:
- ChatGPT-5.4 Thinking: Available to Plus, Team and Pro subscribers
- ChatGPT-5.4 Pro: Offered only to Pro and Enterprise subscribers
- Free users: No access at this stage
OpenAI also announced a new Excel add-in powered by the GPT-5.4 Thinking engine. This add-in makes it possible to build financial models, update existing spreadsheets and run complex data analyses with natural language commands.
How Is It Different From GPT-5.3 Instant?
The recently announced GPT-5.3 Instant focused on producing fast answers and improving the everyday chat experience: fewer refusals, more fluent language, reduced hallucination. GPT-5.4 targets a different user segment. Not everyday chat but complex problem solving; not quick answers but in-depth analysis and multi-step workflows. The two are not rivals but complements. With this strategy, OpenAI is clearly segmenting its model portfolio: Instant for everyday use, GPT-5.4 for professional work.
The Age of Specialization in AI Models
The launch of ChatGPT-5.4 reinforces a trend that is becoming clear in the 2026 AI market: specialization. The era of "general-purpose superiority", where a single model claimed to be the best at everything, is closing; in its place rises a multi-model approach, where each model goes deep in specific areas and professionals choose different models per task.
For developers and professionals, this is both an opportunity and a source of complexity. Choosing the right model is no longer a preference but a strategic decision. Claude for coding, Gemini for research, GPT-5.4 for professional workflows, Grok for real-time information... Using AI in 2026 is like a conductor managing the instruments of an orchestra.
