Sam Altman's OpenAI on Thursday launched ChatGPT-5, a more powerful version of the artificial intelligence model. The CEO described it as ‘very smart, intuitive, and fast’.

In a post on X, Altman said that GPT-5 is an integrated model, which means "no more model switcher and it decides when it needs to think harder or not".
"It is very smart, intuitive, and fast. It is available to everyone, including the free tier, with reasoning!" he added.
GPT-5 is designed to be better capable of coding and creative writing as well as reasoning with complex queries. The OpenAI CEO said that the new version will be rolled out to ChatGPT free, plus, pro, and team users on Thursday, whereas enterprise and education users will receive it next week.
Altman said that making GPT-5 available in the free tier is a big deal to OpenAI, as it provides everyone with PhD-level intelligence. He said that users will get much higher rate limits, while pro users get GPT-5 pro; "really smart!"

Sam Altman explains GPT-5 features
- OpenAI chief Sam Altman said that ChatGPT-5 can explain complex concepts by making something interactive, churning out hundreds of lines of code in a couple of minutes.
- He said that GPT-5 is also much better at writing. "For example, here is GPT-4o writing a eulogy for our previous models (which we are sunsetting) vs GPT-5," he added while posting an image of the two versions.
- Altman said that the new model is good at writing software as well. He posted images of GPT-5 making a web app to learn French, with feature requests including a snake-like game with a mouse and cheese and French words. On a side note, the OpenAI CEO said that users can also come up with better variations of the snake, asking them to give the feature a try and share it.
