OpenAI unveils free model GPT-4o that can interact with visual, audio, text

ChatGPT maker OpenAI said on Monday it would release a new AI model called GPT-4o, which reasons across voice, text and vision.

OpenAI’s chief technology officer, Mira Murati, said during a livestream event that the new GPT-4o model would be offered for free because it is more efficient than the company’s previous models.

OpenAI researchers showed off ChatGPT’s new voice assistant capabilities. In one demonstration, the ChatGPT voice assistant was able to read out a bedtime story in different voices, emotions and tones.
