OpenAI Launches GPT-5, Now Rolling Out to ChatGPT Users
OpenAI has released GPT-5 (Aug. 7, 2025), calling it its smartest and most useful model yet. It’s built to think when needed and sprint when it doesn’t, folding speed and deeper reasoning into one system. Critically, GPT-5 becomes the new default in ChatGPT for signed-in users—marking OpenAI’s biggest upgrade since GPT-4 and a fresh push to make expert-level assistance feel immediate, not academic.
Under the hood, GPT-5 runs as a unified stack: a quick-response model for everyday prompts, a “GPT-5 Thinking” mode for tougher problems, and routing that picks the right approach automatically. The result? Stronger coding help, more nuanced writing, and better performance on health queries—alongside notable cuts to hallucinations and clearer limits when tasks aren’t feasible. It’s multimodal, long-context, and—importantly—trained to be less sycophantic, more direct, and easier to steer.
Availability is already rolling out: Plus, Pro, Team (and even free, with tighter limits) get GPT-5 now, with Enterprise and Edu up next. Developers can tap the API with GPT-5, 5-mini, and 5-nano, while power users unlock GPT-5 Pro for extended reasoning on the gnarliest work. If GPT-4 made AI feel helpful, GPT-5 aims to make it habitual—embedded in daily tasks, not just demos.
