The new tier, Duolingo Max, unlocks two new AI-powered features called “Roleplay” and “Explain My Answer.” The announcement comes the same day that OpenAI released its next-generation GPT-4 AI language model. > The Roleplay feature unlocks an AI chatbot that allows users to practice real world conversation skills with characters in the app. Users will be chatting with an AI that is both responsive and interactive, thanks to GPT-4. The feature guides users through different scenarios. For instance, you can pretend to order coffee at a café in Paris or discuss future vacation plans with a certain character in the app. After users are done with the conversation, they will get AI-powered feedback on the accuracy and complexity of their responses, as well as tips for future conversations.
