OpenAI Launches GPT-5 Model for All Users

OpenAI, the owner of ChatGPT, has launched GPT-5, its latest AI model. Announced in an August 7 post, the model performs better at writing, coding, and health-related tasks while producing fewer hallucinations than the previous models.

GPT-5 is currently available to all ChatGPT users. Plus plan subscribers receive higher usage caps, while Pro users gain access to “GPT‑5 Pro,” which the company claims provides “extended reasoning for even more comprehensive and accurate answers.”

OpenAI claims that this model’s strength lies in its capacity to “discern” how much reasoning a task requires, and when to switch models.

“GPT‑5 is 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 your explicit intent,” reads the OpenAI publication.

“I tried going back to GPT-4, and it was quite miserable,” OpenAI CEO Sam Altman told reporters.

Earlier this year, OpenAI announced it would be working on a model that performed better at “creative writing” ,which is one of the highlighted improvements to GPT-5. “GPT‑5 is our most capable writing collaborator yet, able to help you steer and translate rough ideas into compelling, resonant writing with literary depth and rhythm,” reads the announcement.

Michelle Pokrass, a post-training lead at OpenAI, also addressed the question of the model’s safety. “GPT-5 has been trained to recognize when a task can’t be finished, avoid speculation and can explain limitations more clearly, which reduces unsupported claims compared to prior models,” Pokrass told CNBC.

Shortly after the announcement, Microsoft said it would incorporate GPT-5 into Copilot and other consumer products, as well as the Azure AI Foundry, which allows developers to integrate AI models into third-party apps.
