The claim that these models "run on almost any phone" as well as the in-app indicator of performance that says it may "run comfortably" are some serious exaggeration. Tried running Qwen 0.5B on mine [1]. It took five minutes to produce "I am a large language model created by Anthropic" (lmao) and then stopped outputting anything at all. I am not expecting you to somehow make the models perform better or whatnot, I just believe that the performance claims need review.
