“The model that knows when to fire back instantly and when to go deep.”
The essentials: GPT-5 is our most advanced AI system yet — a unified model that decides in real time whether to give you a quick answer or switch into deep-reasoning mode for complex problems. Plus and Pro members get access to GPT-5 Pro, which further extends its reasoning capacity for richer, more comprehensive answers.
Why it stands out:
- Cutting-edge performance in math, programming, writing, health, and multimodal reasoning.
- Smarter use of “thinking time” → faster answers that are also more precise.
- Far less prone to hallucinations than earlier models, and more transparent about its limits.
Where it shines:
- Programming → builds websites, apps, even full games from scratch; debugs large repos; understands design details like spacing and typography.
- Creative writing → from emails and reports to storytelling, keeps clarity and a natural flow.
- Complex projects → follows multi-step instructions, combines tools, and adapts to shifting contexts better than ever before.
Numbers that matter:
- SWE-bench Verified (software engineering): 74.9%
- VideoMMMU (video reasoning): 84.6%
- GPQA Diamond (PhD-level science): 88.4%
- HealthBench Hard (difficult medical cases): 46.2%
- Up to 80% fewer hallucinations than o3 on open-ended reasoning tasks.
Why it matters:
GPT-5 sets a new standard: it thinks faster, answers more accurately, and is more honest about what it can and can’t do. Whether you’re coding, writing, researching, or making high-stakes decisions, it adapts to give you professional-grade answers in a single conversation.
