In this video, Martin Compton explores the limitations and potential inaccuracies of ChatGPT, Google Bard, and Microsoft Bing chat, particularly when it comes to summarizing external texts or web content. By testing these AI tools on an article he co-authored with Dr Rebecca Lindner, the speaker demonstrates that while ChatGPT and Google Bard may produce seemingly authoritative but false summaries, Microsoft Bing chat, which integrates GPT-4 with search functionality, can provide a more accurate summary. The speaker emphasizes the importance of understanding the limitations of these tools and communicating these limitations to students. Experimentation and keeping up to date with the latest AI tools can help educators better integrate them into their teaching and assessment practices, while also supporting students in developing AI literacy.
