In fact, something of a symbiotic relationship quickly emerged from the working practices, with both companies providing feedback on their use cases and operations that were used to mutually improve the operations and user experience of their products.īicknell tells me, "It was a long process … the very basic prototyping … didn't take long at all … was put together in a day. This lets users get an explanation about why an answer they have been given to a question may have been graded as correct or incorrect and receive a detailed, personalized explanation just as if they were sitting and talking to a human tutor.īicknell says, "This is a very helpful feature …we're really pushing Duolingo closer to our ideal of being everyone's personalized tutor in ways that we haven't been able to do before – we're very excited about how these features will help people's language learning."ĭeveloping these features involved building a close working relationship with AI and data engineers and software developers at OpenAI. The second GPT-4-enabled feature that’s already been made available is called Explain My Answer. In order to make the experience more engaging, the characters are designed as fully fleshed-out personas with their own personality and backstory that the learners can find out about through conversing and interacting. Users are able to order drinks, specify how they would like them to be made, and converse with the barista on a number of different subjects. One example involves conversing with an AI barista in a Parisian café. The first is a role-playing feature that allows users to interact with an AI-powered persona and carry out various learning-focused tasks. This means it is capable of giving more detailed, accurate, and fluent answers to the questions it’s asked.īicknell tells me, "It's very exciting … we were blown away by how powerful the model was, and we immediately sat down and said, ok, with a large language model (LLM) this powerful, what kinds of things have we wanted to do in the past … that the tech just wasn’t there for?”īicknell’s team settled on two initial use cases, which are now available to users of the app. It is reported to have been trained on one trillion parameters (pieces of information), compared to GPT-3’s 175 billion. GPT-4 is said to be significantly more powerful and sophisticated than GPT-3, which many people reading this will be familiar with, thanks to ChatGPT. ![]() With its partnership with OpenAI, Duolingo becomes one of the first third-party organizations to officially license and release a GPT-4 powered product. It also automatically creates test items, assesses the level of difficulty of its tests, automatically grades candidates, and reviews overall performance before test scores are released. Here, AI is used during remotely-administered tests carried out over webcam to detect different methods of cheating that candidates may attempt. This gives users of the app platforms real-time feedback on the way they are using language as well as tips on how it could be improved.ĪI is also extensively used across the company’s English testing system, which is used by over 4,000 institutions, including universities, colleges, and government organizations, to assess the competency of non-native speakers. An example of this is automated feedback on the speech and grammar exercises that students are asked to complete. ![]() Another key use case at Duolingo revolves around creating interactive learning experiences.
