OpenAI has begun rolling out GPT-5, the latest iteration of its flagship language model, to all ChatGPT users.
The company’s CEO Sam Altman called GPT-5 “a significant step along the path to AGI” during a press briefing on Wednesday. While he stopped short of claiming the model reaches artificial general intelligence, Altman noted the latest release is “clearly a model that is generally intelligent.” He added that GPT-5 still lacks key traits that would make it reach AGI, a notably loose term that is defined in OpenAI’s charter as “a highly autonomous system that outperforms humans at most economically valuable work.” For example, the model still lacks the ability to learn continuously after deployment. OpenAI claims GPT-5 is smarter, faster, more useful, and more accurate, with a lower hallucination rate than previous models. In characteristically lofty terms, Altman likened the leap from GPT-4 to GPT-5 to the iPhone’s shift from pixelated to a Retina display. “GPT-5 is the first time that it really feels like talking to an expert in any topic, like a PhD level expert,” Altman said. As part of Thursday’s launch, OpenAI announced two new model variants: a lightweight GPT-5-mini and an even faster, cheaper, GPT-5-nano (which is only in the API). According to OpenAI, free users will get access to GPT-5 and GPT-5-mini, while the Plus subscription includes the same models with “significantly higher” usage limits. OpenAI says that the $200 a month Pro tier offers unlimited GPT-5 access, along with GPT-5-pro, a more powerful version of the model, and GPT-5-thinking, which allows the model to process a query for longer than usual. Pro users will still have access to pick through legacy models.

Full explainer : OpenAI prices GPT-5 at $1.25/1M input tokens and $10/1M output tokens, GPT-5 mini at $0.25/1M and $2/1M, and GPT-5 nano at $0.05/1M and $0.40/1M, respectively.
