GPT-5

GPT‑5 is a major leap forward, delivering top-tier performance in coding, math, writing, health, visual tasks, and more. Built as a unified system, it knows when to respond fast and when to take time for deeper reasoning. Available to all users, GPT‑5 offers extended usage for Plus subscribers, while Pro users unlock GPT‑5 Pro our most powerful version with enhanced expert-level capabilities.

One Unified System in GPT‑5

GPT‑5 introduces a smart unified system combining a fast, general-purpose model, a deeper reasoning engine ("GPT‑5 Thinking") for complex tasks, and a real-time router that picks the right one based on context and user intent like when you say "think hard about this." The router learns and improves over time using real-world feedback. When usage limits are hit, lightweight model versions take over. Soon, all these features will merge into a single, seamless model.

GPT‑5: Smarter and More Practical Than Ever

GPT‑5 is not only faster and more accurate it’s also more useful in everyday scenarios. With major improvements in reducing hallucinations, following instructions, and avoiding sycophantic responses, GPT‑5 excels in writing, coding, and health-related tasks.

Best-in-Class for Coding

GPT‑5 is our most powerful coding model yet, especially in front-end development and debugging large codebases. It can generate stunning, responsive websites and apps from a single prompt, with a strong sense of design, spacing, and typography. Developers can now go from idea to polished product faster than ever.

Creative Writing Meets Intelligence

GPT‑5 is our most advanced writing partner yet, transforming rough ideas into compelling prose with depth, rhythm, and clarity. It handles complex forms like unrhymed iambic pentameter or natural flowing free verse, while also making everyday writing like reports, emails, and memos easier and more effective.

Smarter Health Guidance

GPT‑5 is also our best model for health-related queries, scoring highest on HealthBench evaluations. It acts as a thoughtful partner flagging concerns, asking relevant follow ups, and tailoring responses to your knowledge and location. While it doesn’t replace a doctor, it helps you ask better questions, understand results, and make more informed decisions.
