ChatGPT employs a deep learning (DL) model constructed using artificial neural networks and designed to analyze input data and extract increasingly complex features (Hu and Buehler 2023). Its chatbot interface makes it easy to use, requiring just a prompt to generate a response from the model. It is capable of producing fluent text in multiple languages, including English, Spanish, and Portuguese, across a broad range of genres such as fiction, poetry, news articles, and academic papers (Chatterjee and Dethlefs 2023; Deng and Ling 2022). Finally, ChatGPT is able to learn from previous conversations and feedback, enabling the model to provide more accurate or contextually relevant responses (Tate et al. 2022). Due to its capabilities, an increasing number of studies are exploring the potential use of ChatGPT across multiple fields, including education (Rudolph, Tan, and Tan 2023), medicine (King 2022), journalism and mass media (Pavlik 2023) and computer science (Chatterjee and Dethlefs 2023). This article outlines and describes specific uses of ChatGPT's capabilities to support foreign language teaching and learning. Next, it highlights some of the current limitations of the artificial intelligence (AI) system and identifies potential issues that may arise from using generative AI systems in foreign language learning and teaching.
