The next landmark version of OpenAI's ChatGPT could use GPT-5, but don't start assuming this will have any semblance of "AGI."

GPT-4.5 could arrive as soon as next week, as Microsoft gets ready to host OpenAI’s latest models.

GPT-5’s debut will be preceded by the release of a less capable large language model, GPT-4.5, in the coming weeks. The latter algorithm is the successor to the company’s general-purpose GPT-4o model. GPT-4o is less adept at tasks such as generating code than OpenAI’s reasoning-optimized LLMs, but it offers significantly lower inference costs.

ChatGPT developer OpenAI's weekly active users surged past 400 million in February, a company spokesperson told Reuters on Thursday, highlighting rapid growth in the adoption of artificial intelligence tools.
