GPT-5.4 just launched — only two days after GPT-5.3 Instant — and the upgrade is far bigger than most people realize.

In this video, we break down everything new in GPT-5.4, including the benchmarks, architecture changes, and real-world capabilities compared to GPT-5.2 and GPT-5.3.

OpenAI’s newest model introduces massive improvements:
• 33% fewer hallucinations
• 2 million token context window
• native computer control (AI that can use your computer)
• dramatic improvements in reasoning benchmarks
• pixel-perfect image understanding

But the real story isn’t just performance — it’s what this means for the future of AI agents, automation, and knowledge work.

We’ll break down:
The GPT-5 model timeline
Benchmark results like GDPval and ARC-AGI-2
The Tool Search architecture upgrade
Why native computer use changes everything
How GPT-5.4 compares to GPT-5.2 and GPT-5.3
