OpenAI is training a new cutting-edge AI model that promises to replace its current flagship product, GPT-4o. "OpenAI has recently begun training its next frontier model and we anticipate the resulting systems to bring us to the next level of capabilities on our path to AGI," or artificial general intelligence, the company says. OpenAI executives have been teasing the next generation ChatGPT as a major advancement, but for now, the company is declining to reveal more, including what the AI model will be called and whether it's the long-awaited GPT-5.
