OpenAI has launched GPT‑5, which the company says features improved performance across coding, math, writing, health, visual perception and more.
“It is a unified system that knows when to respond quickly and when to think longer to provide expert-level responses,” according to OpenAI.
GPT‑5 is available to all users, with Plus subscribers getting more usage, and Pro subscribers getting access to GPT‑5 pro, a version with extended reasoning for even more comprehensive and accurate answers.
Open AI describes GPT‑5 as a unified system with a smart, efficient model that answers most questions, a deeper reasoning model (GPT‑5 thinking) for harder problems, and a real‑time router that quickly decides which to use based on conversation type, complexity, tool needs, and user’s explicit intent.
It claims that the router is continuously trained on real signals, including when users switch models, preference rates for responses, and measured correctness, improving over time. Once usage limits are reached, a mini version of each model handles remaining queries.
Open AI plans to integrate these capabilities into a single model in the near future.
It adds that GPT‑5 is more useful for real-world queries, with significant advances made in reducing hallucinations, improving instruction following, and minimising sycophancy.
