On March 5, 2026, OpenAI released GPT-5.4 — its latest AI model supporting a context window of up to 1,050,000 tokens and a maximum output of 128,000 tokens, along with native computer use capabilities. It is the first general-purpose model that can directly operate computers, enabling AI agents to carry out complex workflows across multiple applications autonomously.

What Is Computer Use — and Why Is It a Game Changer?
Computer Use is the ability of an AI to directly operate a computer — opening applications, clicking buttons, typing text, navigating between screens. It is like having a digital employee sitting at a workstation performing tasks on your behalf.
While computer use has existed in some AI models (such as Claude Computer Use), GPT-5.4 is the first general-purpose model to integrate this capability natively — no additional installation or special configuration required.
Examples of Computer Use in Enterprise Settings
- Open an ERP system, pull monthly sales reports, and summarize them in an email automatically
- Review purchase orders in the procurement system and compare prices across multiple vendors
- Transfer data from Excel spreadsheets into the accounting system automatically
- Search multiple systems simultaneously and compile executive summary reports
Agentic Workflows and Tool Search — How Much Can AI Do Autonomously?
GPT-5.4 does not just answer questions — it can plan and execute complex tasks across multiple applications on its own through what is called Agentic Workflows. The AI operates as an "agent" that receives a task assignment, plans the steps, selects tools, and executes until completion.
Tool Search is a new feature that helps AI agents find and select the right tools for each task efficiently — like an employee who knows exactly which software to use for which task.
| Capability | Description | Use Case Example |
|---|---|---|
| Computer Use | Direct computer control — clicking, typing, navigating | Open ERP system and pull reports |
| Tool Search | Automatically finds and selects the right tools | Choose between API, database, web browser per task |
| Agentic Workflows | Plans and executes cross-app tasks autonomously | Receive "summarize this month's expenses" and handle all steps |
| 1M Context Window | Read up to ~3,000 pages of documents in a single session | Analyze entire contracts and compare against requirements |
| Thinking Mode | Advanced reasoning for coding and logic tasks | Debug code, analyze complex problems |
GPT-5.4 Thinking — OpenAI's Flagship Model
GPT-5.4 Thinking is the version OpenAI calls its "Flagship Model" — combining everything into one package: advanced reasoning, coding, and agentic workflows. It is designed for tasks requiring deep analytical thinking, such as strategic planning, financial data analysis, or debugging complex code.
GPT-5.1 Deprecated — Time to Migrate!
OpenAI announced that GPT-5.1 has been deprecated as of March 11, 2026 — meaning organizations still using GPT-5.1 through the API must plan their migration to GPT-5.4 promptly. Applications relying on GPT-5.1 will stop working in the near future.
Warning for Developers
If your organization uses GPT-5.1 via the API, test GPT-5.4 in your staging environment first. The 8x larger context window may significantly affect token costs and latency compared to your current setup.
Impact on ERP — AI Agents Are Transforming Enterprise Operations
GPT-5.4's agentic workflow capabilities have direct implications for ERP systems — because AI agents can now operate across ERP modules autonomously, from procurement to accounting and reporting.
| ERP Module | Tasks AI Agents Can Perform | Benefits |
|---|---|---|
| Procurement | Compare prices, verify terms, auto-generate PR/PO | Reduce procurement time by 60-70% |
| Accounting | Detect anomalies, reconcile accounts, generate financial reports | Reduce errors + faster month-end closing |
| Inventory | Monitor stock levels, alert on low inventory, auto-reorder | Eliminate stockout issues |
| Executive Reporting | Pull data from all modules, compile dashboards with recommendations | Faster decisions with real-time data |

Saeree ERP by Grand Linux Solution Co., Ltd. is currently developing an AI Assistant that will help users work with the ERP system more efficiently — aligned with the agentic workflow direction that GPT-5.4 is establishing as an industry standard. Stay updated on progress by contacting our team.
OSWorld-V Benchmark — GPT-5.4 Scores 75%
OSWorld-V is a benchmark that tests an AI's ability to use computers in real-world scenarios — opening programs, navigating menus, filling in data, working across applications. GPT-5.4 scored 75%, which is remarkably high for this type of benchmark and signals that AI is approaching the point where it can replace humans in many operational tasks.
Summary — What GPT-5.4 Changes for Organizations
| Change | Impact on Organizations |
|---|---|
| 1M Token Context | Analyze entire documents without chunking — ideal for contracts, financial statements, policies |
| Computer Use | AI operates computer screens like a human — eliminates repetitive manual tasks |
| Agentic Workflows | AI plans and executes complex cross-app tasks — transforms how organizations work |
| GPT-5.1 Deprecated | Organizations using GPT-5.1 must plan migration promptly |
| ERP + AI Agents | ERP systems that support AI agents will gain a competitive advantage |
"GPT-5.4 is not just a smarter model — it is the first step toward AI that can truly work like a human: controlling computers, operating across applications, and making decisions autonomously. Organizations that prepare for agentic AI will lead the next era."
