OpenAI has teased the launch by posting “LIVE5TREAM THURSDAY” on X.
Sun.: Sam Altman posted a screenshot with “ChatGPT 5” in the top-left corner.
GPT-5’s early testers are impressed with its coding and problem-solving abilities.
The leap from GPT-4 to GPT-5 is not likely to be as large as that from GPT-3 to GPT-4, though.
Challenges for OpenAI include lack of new algorithms, data limitations, and hardware-induced failures during training.

OpenAI is offering ChatGPT’s enterprise version, which includes enhanced security and privacy features.
The move is likely an attempt to get closer to the Trump administration.
It follows GSA’s approval of OpenAI, Google, and Anthropic as vendors in its new AI marketplace.
OpenAI has also formed a government user group, with tailored training and partners like Slalom and BCG.
OpenAI said it won’t use data from federal workers to train or improve its models.
“This is almost like it’s a trial run in some ways,” GSA’s Federal Acquisition Service commissioner Josh Gruenbaum said.
