Image: OpenAI GPT-5.4 Is Here: Computer Use, 1M Context, and OpenAI's Most Complete Model Yet
OpenAI releases GPT-5.4 with native computer-use capabilities, 1M token context, scalable tool search, and best-in-class agentic coding. Full breakdown of benchmarks, pricing, and what it means for developers.
OpenAI just dropped GPT-5.4, and it’s not an incremental bump. This is the first general-purpose model with native computer-use capabilities, a 1M token context window in Codex and the API, and a new tool search system that changes how agents interact with large toolsets. It shipped today, March 5, 2026, across ChatGPT, the API, and Codex.
The official announcement describes GPT-5.4 as “designed for professional work.” That’s accurate. This release merges the coding muscle of GPT-5.3-Codex with broad improvements to reasoning, vision, tool use, and knowledge work, creating a single model that handles what previously took specialized variants.

What’s Actually New
GPT-5.4 ships in two variants: the standard gpt-5.4 and gpt-5.4-pro for maximum performance on complex tasks. In ChatGPT, it appears as GPT-5.4 Thinking, replacing GPT-5.2 as the default reasoning model for Plus, Team, and Pro users.
Here’s the headline summary:
- Native computer use: First general-purpose model that can operate computers, navigate desktops, and interact with applications through screenshots and keyboard/mouse actions
- 1M token context: Experimental support in Codex, with requests beyond 272K tokens priced at 2x
- Tool search: New API feature that lets the model efficiently search through large tool collections instead of loading every tool definition upfront
- Token efficiency: Uses significantly fewer reasoning tokens than GPT-5.2 to solve problems, reducing costs for tool-heavy workflows
- Mid-response steering: GPT-5.4 Thinking shows an upfront plan and lets you adjust course while it’s still working
The Benchmarks
The numbers tell a clear story. GPT-5.4 posts strong improvements across every category, with the biggest jumps in computer use and knowledge work.
Headline Numbers
| Benchmark | GPT-5.4 | GPT-5.3-Codex | GPT-5.2 |
|---|---|---|---|
| GDPval (knowledge work) | 83.0% | 70.9% | 70.9% |
| SWE-Bench Pro | 57.7% | 56.8% | 55.6% |
| OSWorld-Verified (computer use) | 75.0% | 74.0% | 47.3% |
| Toolathlon | 54.6% | 51.9% | 46.3% |
| BrowseComp (web search) | 82.7% | 77.3% | 65.8% |
The GDPval result is the standout: 83.0% on a benchmark that tests agents across 44 occupations. That’s a 12-point jump from GPT-5.2.
Computer Use Benchmarks
This is where GPT-5.4 really separates itself.
| Benchmark | GPT-5.4 | Human | GPT-5.2 |
|---|---|---|---|
| OSWorld-Verified | 75.0% | 72.4% | 47.3% |
| WebArena-Verified | 67.3% | — | 65.4% |
| Online-Mind2Web | 92.8% | — | — |
GPT-5.4 surpasses human performance on OSWorld-Verified, which measures a model’s ability to navigate desktop environments through screenshots and keyboard/mouse actions. That 75.0% vs. 72.4% human baseline is a first for a general-purpose model.
Academic and Reasoning
| Benchmark | GPT-5.4 | GPT-5.4 Pro | GPT-5.2 |
|---|---|---|---|
| ARC-AGI-2 | 73.3% | 83.3% | 52.9% |
| FrontierMath Tier 4 | 27.1% | 38.0% | 18.8% |
| Humanity’s Last Exam (tools) | 52.1% | 58.7% | 45.5% |
| GPQA Diamond | 92.8% | 94.4% | 92.4% |
The ARC-AGI-2 jump is dramatic: from 52.9% to 73.3% (or 83.3% with Pro). That benchmark tests abstract reasoning, and a 20+ point improvement in a single generation is unusual.
Computer Use: The Headline Feature
GPT-5.4 is OpenAI’s first general-purpose model with native computer-use capabilities. It can interpret screenshots, navigate desktop and browser environments, click elements, type text, and carry out multi-step workflows across applications.
OpenAI designed it to handle a range of workloads: bulk data entry across portals, email and calendar management, form filling, and web-based workflows. The model interacts through coordinated keyboard and mouse actions based on what it sees on screen.
For developers, the capabilities are available through an updated computer tool in the API. OpenAI also released a new Playwright Interactive skill for Codex that lets GPT-5.4 visually debug web and Electron apps, including testing apps it just built.
Vision improvements underpin the computer-use capability. On MMMU-Pro (visual understanding and reasoning), GPT-5.4 hits 81.2% without tool use. A new original image input detail level supports full-fidelity perception up to 10.24 million pixels.
Tool Search: A Quiet Architecture Shift
The tool search feature might be the most practically important addition for developers building agents.
Previously, every tool definition had to be included upfront in the prompt. With 36 MCP servers enabled, that meant thousands of tokens burned before the model even started thinking. Tool search changes this: GPT-5.4 receives a lightweight list of available tools plus a search index. When it needs a tool, it searches and retrieves just the relevant definition.
OpenAI tested this on Scale’s MCP Atlas benchmark with all 36 MCP servers. The result: dramatically fewer tokens consumed while maintaining or improving task completion. For anyone building agents that coordinate across multiple services, this is a real cost and latency reduction.
Coding: Merging Codex Into the Mainline
GPT-5.4 is the first mainline reasoning model that incorporates the frontier coding capabilities previously exclusive to the GPT-5.3-Codex specialist model. You no longer need a separate model for coding tasks.
The coding highlights:
- SWE-Bench Pro: 57.7%, improving on GPT-5.3-Codex’s 56.8%
- Terminal-Bench 2.0: 75.1% (GPT-5.2 scored 62.2%)
- Codex /fast mode: Up to 1.5x faster token velocity
- Frontend focus: Notable improvements in complex frontend tasks
OpenAI showcased the model building complete games from single prompts: a theme park simulation game, an RPG, and a Golden Gate Bridge flyover, all using the Playwright Interactive skill to visually test what it built.
Early Industry Reactions
Several companies shared early evaluations:
“GPT-5.4 is the best model we’ve ever tried. It’s now top of the leaderboard on our APEX-Agents benchmark.” Brendan Foody, CEO at Mercor
“GPT-5.4 sets a new bar for document-heavy legal work. On our BigLaw Bench eval, it scored 91%.” Niko Grupen, Head of Applied Research at Harvey
“Developers don’t just need a model that writes code. They need one that thinks through problems the way they do.” Mario Rodriguez, Chief Product Officer at GitHub
“GPT-5.4 xhigh is the new state of the art for multi-step tool use.” Wade, CEO at Zapier
Quotes also came from JetBrains, Cursor, Augment Code, Windsurf, Thomson Reuters, Notion, Databricks, and Whoop, all featured on the announcement page.
Pricing and Availability
GPT-5.4 is rolling out today across ChatGPT and Codex. In the API, it’s available now as gpt-5.4 and gpt-5.4-pro.
| Model | Input | Cached Input | Output |
|---|---|---|---|
| gpt-5.4 | $2.50/M tokens | $0.25/M tokens | $15/M tokens |
| gpt-5.4-pro | $30/M tokens | — | $180/M tokens |
| gpt-5.2 (prev) | $1.75/M tokens | $0.175/M tokens | $14/M tokens |
That’s a roughly 43% increase in input pricing and a modest 7% increase in output pricing over GPT-5.2. The cached input price remains at 10x discount, which matters for agents that make repeated similar calls.
The 1M context window in Codex is experimental. Requests exceeding the standard 272K window count at 2x normal pricing. Enterprise customers can try the new ChatGPT for Excel add-in, also launched today.
Safety Notes
OpenAI rates GPT-5.4’s cybersecurity capabilities as dual-use and maintains a “precautionary approach.” The release includes an expanded cyber safety stack with monitoring systems, trusted access controls, and enhanced audit trails. The full system card is available for review.
On chain-of-thought monitoring, OpenAI reports continued research into whether models can deliberately obfuscate their reasoning to evade safety monitoring. They’re publishing updated findings on CoT controllability.
What This Means for the AI Coding Landscape
GPT-5.4 is a consolidation play. Instead of shipping specialized models for coding, reasoning, and vision separately, OpenAI has merged them into a single frontier model that handles all three. That simplifies the developer experience significantly. You don’t need to route between models anymore.
The computer-use capability puts OpenAI in direct competition with Anthropic’s Claude computer use features, and the 75.0% OSWorld score (surpassing human performance) gives them a strong opening position. The tool search feature, meanwhile, addresses a real pain point that anyone building MCP-based agents has felt: prompt bloat from too many tool definitions.
For the competitive picture: GPT-5.4’s 1M context window in Codex matches what Claude Opus 4.6 offers. The pricing is roughly in line with Anthropic’s rates. The real differentiators are the native computer use in a general-purpose model and the tool search architecture.
The AI coding wars keep accelerating. OpenAI’s release cadence has compressed from months to weeks, with GPT-5.3-Codex (February 5), GPT-5.3-Codex-Spark (February 12), GPT-5.3 Instant (March 3), and now GPT-5.4 (March 5) all shipping within a single month. For developers building on these models, the challenge isn’t capability anymore. It’s keeping up.
