GPT-5.4 for ChatGPT Users
ChatGPT just got faster, smarter, and free users got a major upgrade. Learn what changed with GPT-5.4, how to access it, and how to get better results.
ChatGPT just got a significant upgrade, and most users don’t know what changed. GPT-5.4 is faster, smarter at reasoning, and — here’s the big one — free users now get access to a smaller version through Thinking mode.
But a new model doesn’t automatically mean better results. You need to know what it’s good at, what’s different about prompting it, and when it’s the right tool vs. when Claude or Gemini might serve you better.
This course cuts through the marketing and shows you what GPT-5.4 actually means for your daily work.
What about GPT-5.5? (April 2026 update)
OpenAI has begun rolling out GPT-5.5 — most visibly inside Codex, where independent benchmarks now show the model scoring around 82.7% on Terminal-Bench 2.0, a meaningful step up from 5.4 on coding-specific tasks. For everyday ChatGPT use (the focus of this course), GPT-5.5 is mostly an incremental improvement on top of 5.4 — same Thinking-mode mechanics, same prompt patterns, same free-tier story. The big differentiator is coding workflows. If you’re a developer interested in the GPT-5.5 codex refactor workflow specifically — what changed for multi-file refactors, where 5.5 wins vs Claude/DeepSeek V4, and the workflow we’re keeping — see our GPT-5.5 TypeScript refactor in Codex blog post. Course content below remains accurate for non-coding ChatGPT use through GPT-5.5.
You’ll start with a clear breakdown of what changed — performance improvements, new features, and what free vs. paid users get. Then you’ll apply GPT-5.4 to five everyday tasks: emails, research, planning, writing, and analysis. Each one includes specific prompting techniques that work better with this model than with older versions.
The later lessons cover Thinking mode (when it’s worth the slower response time and when it isn’t) and an honest comparison with Claude and other alternatives.
