GPT-5 is not in training and “won’t for some time,” OpenAI CEO confirms


OpenAI CEO Sam Altman addresses the famous “AI pause” open letter signed by many prominent figures in research and industry. He also provides an update on GPT-5.

An open letter from the Future of Life Institute, a non-profit organization whose mission is to avert existential threats to humanity, called for a six-month pause to come up with rules. The letter generated a lot of discussion and was certainly valuable in that sense, but despite some prominent signatories like Yoshua Bengio and Elon Musk, it is unlikely to result in a pause. Nevertheless, GPT-5 is not yet in the starting blocks.

GPT-5 isn’t in training yet

At year event on AI in business at MIT featuring tech podcaster Lex Fridman, OpenAI researcher Andrej Karpathy, and physicist Stephen Wolfram, OpenAI CEO Sam Altman spoke via video livestream.

Altman addressed the open letter: An earlier version of the letter incorrectly claimed that GPT-5 was already in training, Altman said. But OpenAI is not yet training GPT-5 and does not plan to do so “for some time,” Altman noted.


Instead, he said, GPT-4 still has safety issues to resolve that are not addressed in the letter. “We are doing other things on top of GPT-4 that, I think, have all sorts of safety issues that are important to address and were totally left out,” Altman said.

Altman’s statement is at odds with a February Morgan Stanley analysis in which the bank used Nvidia financial data on graphics card sales to claim that GPT-5 training had begun.

OpenAI must first get a grip on GPT-4

By “other things on top of GPT-4”, Altman probably means ChatGPT plugins, which provide GPT-4 with Internet access, extended code capabilities, and numerous new applications. In addition, OpenAI is likely to release new and better versions of GPT-4 occasionally, as it did with GPT 3.5. We know that there is a version of GPT-4 that can handle images and up to 32K tokens, which is currently only available to select people.

The introduction of the plugins also emphasized that OpenAI is thinking far beyond text generation for its language models: Plugins extend the capabilities of language models with tools for images, code, web access, or search, to the point where the model can serve as a language interface for solving many tasks. OpenAI’s study of the impact of large language models on the labor market refers specifically to language models with access to tools.

In short, OpenAI has big plans for GPT-4. The language model could become an ecosystem, and the economic and social impact could be significant. With no economic, technical, or regulatory foundation yet in place, OpenAI has little reason to rush GPT-5 to market.
