The CEO of Stability AI, developer of text-to-image generator Stable Diffusion, said OpenAI's latest AI model GPT-4 is the "best therapist". "I use [it] every day," Emad Mostaque said. He further denied that the AI industry is in a bubble and said it's "bigger than 5G or self-driving cars". Mostaque was speaking at Cerebral Valley AI Summit in San Francisco.
