GPT-4.5 is still OpenAI ’s most ambitious drop to date.

Released in late February as a research preview, it uses more computing power than its previous models and was trained on more data.

Paid subscribers will be the first to get access to the new model, but the company does not yet have a plan to release it to all users.

GPT-4.5 makes ChatGPT feel less annoying and more conversational.

CEO Sam Altman described the vibe of the new model as similar to chatting with a thoughtful human.

Altman floated the idea online of switching OpenAI ’s subscription offerings into a credit-per-use system.
