Yes it is and has been for a very long time, it has been years now. Gemini 1.5 Pro is when LLM translations started significantly outperforming non-LLM machine translation, and that came out over 2 years ago.

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.

I translate texts between Ukrainian, Russian and English dozens of times daily. The LLM translation is not only better, it's also refineable, you can chat with the AI to make changes to what you meant.

I've been using gemma4 for translating Mongolian to English. It runs circles around Google Translate for that language pair, it's not even close.
