What does better mean here? Does it handle formal vs informal speech? Idiomatic expressions? Regional variances (like American vs British English)? These are areas where Google Translate is weak.
How fast are we talking here (including initial loading times) and what's the impact on your phone battery? Also, what iPhone do you have?
I am really interested in this application hence my questions.
Ever since then Google models have been the strongest at translation across the board, so it's no surprise Gemma 4 does well. Gemini 3 Flash is better at translation than any Claude or GPT model. OpenAI models have always been weakest at it, continuing to this day. It's quite interesting how these characteristics have stayed stable over time and many model versions.
I'm primarily talking about non-trivial language pairs, something like English<>Spanish is so "easy" now it's hard to distinguish the strong models.
