Our team at Vercel used AI-based logic to improve their domain registry experience for international domains by fixing edge-case errors in their code, specifically when dealing with Punycode format domains containing non-English characters. The issue was caused by an optional language code not being utilized and a library like CLD2 failing to accurately determine the language due to short domain names. They turned to the Vercel AI SDK and chose a model that could generate a 3-character language code, successfully identifying the correct codes for all domains with a 100% success rate in testing, leading to improved user experience and functionality of their platform.
