Another new anonymous model on Arena, Kerria, runs on Qwen's tokenizer 🌼 Same chat-box tokenizer test as Kalmia: in Code Arena, Kerria garbled 3 of the 4 tokens that only Qwen models trip over, and none of the 52 from 13 other labs, including Kimi, DeepSeek, OpenAI, Google and Mistral. Alibaba has used K names on Arena before: Kiteki, Kizen-alpha and Korin were previews of Qwen 3.5, 3.6 and 3.7 Max. A few other labs build on Qwen's tokenizer, so this isn't proof.
