Overview
ChatGPT needs no introduction — it's the model that put AI in everyone's hands. GPT-5.4 is OpenAI's latest and most capable release, launched just days ago on March 5, 2026.
The headline feature is native computer use: GPT-5.4 can control your desktop directly — clicking, typing, navigating software using screenshots and mouse/keyboard input. On the OSWorld-Verified benchmark, it actually exceeds human performance (75.0% vs. 72.4%). This isn't a toy demo; it's a legitimate workflow automation tool.
GPT-5.4 Thinking provides inline thinking plans — you can see its reasoning process upfront and interrupt if the plan veers off course. This saves hours of back-and-forth that previous models required.
The free tier runs GPT-5.2 (no access to 5.4). For GPT-5.4 Thinking, you need at minimum ChatGPT Plus at $20/month. The Pro tier ($200/month) gets you unlimited access to GPT-5.4 Pro with dedicated GPU resources.

Limitations
Hallucinations reduced but not eliminated — ~89% of errors are presented with high confidence ("bluffs")
Overactive safety guardrails can block legitimate professional requests (false positives)
Overkill for simple tasks — too resource-heavy and expensive for basic queries
Multi-step reasoning can lose track of earlier assumptions across complex chains
Extended context (>272K) costs 2x on input tokens, making the 1M window expensive
No GPT-5.4 on free or Go tiers — minimum Plus ($20/mo) required
OpenAI plans to introduce ads in the free and Go tiers
