OpenAI Launches New GPT-5 AI Model for ChatGPT Users

OpenAI is launching a new ChatGPT-5 AI model for its users, per a Thursday announcement. GPT-5is available to everyone, including its free users. OpenAI says the model is smarter, faster, and more useful, particularly across domains like writing, coding, and health care.

“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,” said Michelle Pokrass, a post-training lead at OpenAI. “I tried going back to GPT-4, and it was quite miserable,” OpenAI CEO Sam Altman added in a briefing with reporters.

Since the original launch of ChatGPT, OpenAI has become a household name in the technology sector, inspiring the ongoing AI rally. The AI developer is worth billions, and its home to millions of users on a daily basis. The company also says it expects to hit 700 million weekly active users on ChatGPT this week alone with the new update.

What ChatGPT-5 Brings

OpenAI said GPT-5’s hallucination rate is lower, which means the model fabricates answers less frequently. The company said it also carried out extensive safety evaluations while developing GPT-5, including 5,000 hours of testing.

According to OpenAI, GPT-5 is now available to OpenAI’s Free, Plus, Pro and Team users. This launch will be the first time that Free users have access to a reasoning model, which is a type of model that “thinks,” or carries out an internal chain of thought, before responding. If Free users hit their usage cap, they’ll have access to GPT-5 mini. Meanwhile, OpenAI’s Plus users have higher usage limits, and Pro users have unlimited access to GPT-5 as well as access to GPT-5 Pro. ChatGPT Edu and ChatGPT Enterprise users will get access to GPT-5 roughly a week from today.
