OpenAI has unveiled GPT-5, the most advanced iteration of its artificial intelligence systems to date. This new model marks a significant evolution in AI, delivering extraordinary performance across a comprehensive range of capabilities, including coding, mathematics, creative writing, health advice, and visual perception. Available to all ChatGPT users, GPT-5 brings a smarter, more versatile, and highly efficient AI experience.

A Unified and Adaptive AI System

GPT-5 is designed as a unified AI system that intuitively recognizes when to respond instantly and when to engage in deeper, expert-level reasoning. It integrates a quick-response model for most queries, a "thinking" model for complex problems, and a real-time routing mechanism that dynamically selects the best approach based on the conversation’s nature and user intent. This routing system continuously improves through feedback such as user model switches and response preferences.

Robust Performance Across Key Domains

OpenAI focused heavily on enhancing GPT-5’s utility in real-world applications, substantially reducing errors like hallucinations and improving adherence to user instructions. Notably, GPT-5 excels in writing, coding, and health-related queries—the three pillars of typical ChatGPT usage.

Coding

GPT-5 is recognized as the strongest coding assistant yet, capable of sophisticated front-end development and debugging large repositories. It can generate engaging websites, apps, and games from simple prompts, with a keen sense of design elements like spacing, typography, and visual aesthetics.

Creative Expression

The model demonstrates exceptional collaboration in writing, capable of crafting nuanced poems and literary works with rhythm, structure, and emotional depth. Its improved textual creativity means it functions not just as an assistant for daily writing tasks, but also as a literary companion.

Health Guidance

GPT-5 raises the bar in providing health information, scoring significantly higher on medical benchmarks. It acts as an informed thought partner, flagging concerns, asking pertinent questions, and tailoring advice according to user context and location—all while emphasizing that it is not a substitute for professional medical advice.

GPT-5 Pro: Extended Reasoning for Complex Challenges

For users tackling the most demanding tasks, GPT-5 Pro offers enhanced computation power with prolonged reasoning capabilities. It achieves superior accuracy and relevance across science, health, math, and coding challenges. External experts favor its responses for thoroughness and precision in real-world applications.

How to Access GPT-5

GPT-5 is now the default model on ChatGPT for all signed-in users, replacing previous versions such as GPT-4o and OpenAI o3. Plus subscribers enjoy expanded usage, while Pro users gain unlimited access including the GPT-5 Pro model. Team, Enterprise, and Education customers receive generous usage limits to support organizational needs. A smaller GPT-5 Mini handles overflow queries, ensuring availability even after usage caps are reached. Team users can also start coding with GPT-5 in the Codex CLI? by signing in with ChatGPT.
