During a recent remote interview at an MIT event, OpenAI CEO Sam Altman confirmed that the company is not developing a fifth version of its generative pretrained transformer (GPT-5) model.

Instead, OpenAI focused on expanding the capabilities of its latest model, GPT-4. Altman answered questions from computer scientist and podcaster Lex Fridman about open letter, which called for the temporary suspension of training of AI models larger than GPT-4 for six months.

Altman pointed out that the letter contained some technical inaccuracies, specifically stating that OpenAI is not currently training GPT-5 and will not be doing so for some time. He called the claim “a bit ridiculous” and explained that the company is currently working on the development of GPT-4, which presents its own set of security issues that need to be addressed.

However, Altman supported other parts of the letter, including the importance of ensuring AI models are safe and consistent with human values. As OpenAI continues its research and development in the field of artificial intelligence, Altman stressed the need to carefully approach security issues while expanding the capabilities of its models.
