Using the AI SDK to fix edge-case errors in our code

Software engineers at Vercel have used AI to improve the domain registry experience for international domains. They discovered that purchasing a Punycode domain, which represents international characters using the ASCII standard, requires an associated language code. Initially, they tried to use the Common Language Detector 2 (CLD2) library to identify the language code but the domain names were too short for the library to work accurately. Instead, the engineers turned to the Vercel AI software development toolkit which, with the GPT-4o model from OpenAI, correctly identified the language codes for each domain. This model was tested with previously failed domain purchases and achieved a 100% success rate. The solution has since been deployed to production.
