GPT-4o was recently introduced, which offers faster speed and enhanced capabilities across text, voice, and vision. It can now understand and discuss images better, supports over 50 languages, and is gradually being rolled out to ChatGPT Plus and Team users. Free users will also benefit from GPT-4o’s features, with message limits. A new ChatGPT desktop app for macOS facilitates integration and voice conversations and a new simplified interface for a more user-friendly experience.
