OpenAI has announced the rollout of a version of Advanced Voice powered by GPT-4o mini for all ChatGPT free users, allowing them to preview the feature daily across platforms. This new version is designed to maintain a natural conversation pace and tone similar to the original GPT-4o while being more cost-effective. Additionally, users with the Plus subscription will receive five times the usage limit of free users, along with added features such as video and screen sharing. Pro users will have unlimited access to Advanced Voice, along with higher limits for video and screen sharing.
