Open AI has released a new AI model called GPT-4o, which enables Chat GPT to engage in realistic voice conversations and interact across both text and images. The model allows users to speak to Chat GPT and receive real-time responses with no delay, and even interrupt it mid-sentence, making conversations feel more natural. This significant advancement brings human-like interaction to AI voice assistants, a feat previously challenging to achieve. The new model will be available for free, with paid users having greater capacity limits.
