The small Gemma models performed best, while Claude Haiku 4.5 and gpt-oss-20b scored significantly lower, with 93% and 70% respectively. The research highlights that Google's models show minimal impact from the script change, while smaller models struggle more with colloquial Tamil and Tanglish versions.",
