OpenAI's GPT-5.4, released March 5, 2026, is the first general-purpose model with native computer-use built in — and it matches or exceeds professionals in 83% of real-work comparisons, up from 70.9% just one model generation ago.
Key Takeaways
- GPT-5.4 is the first general-purpose model with native computer-use — it can operate apps, browsers, and workflows without a separate plugin
- Professional benchmark jump: 83.0% on GDPval (44-occupation professional comparisons), up from 70.9% in GPT-5.2 — a 12-point leap in one generation
- 1 million token context window enables genuine long-horizon agentic tasks without chunking
- 33% fewer factual errors versus GPT-5.2, verified on internal and third-party benchmarks
- Two variants: GPT-5.4 Thinking (reasoning-focused) and GPT-5.4 Pro (high-performance throughput)
- GPT-5.1 deprecated the same week — OpenAI is compressing its release cadence significantly
- Record scores on OSWorld-Verified and WebArena-Verified (real-world computer-use benchmarks), not just synthetic tests
