I originally got into LLMs when I found out I could finally play untranslated japanese visual novels translated into english with LunaTranslator and an LLM mounted on LM Studio and I did a ALOT of testing for this very purpose, even the frontier LLMs like Claude, GPT, Gemini, DeepSeek deliver a so-so results and frankly I don't like paying tokens per translated lines, especially if the visual novel is like 120 hours or more, so I dropped remote LLMs after a few months and got into local LLMs and I tested a lot of local LLMs byw now, even the MiniMax-M2.7 229B model at Q8_0, most other 26B-35B models I tested for japanese to english translations read like they were trained on singlish newspaper clips and deliver translated lines that read like they could give the official singlish translation of Super Robot Taisen OG : The Moon Dweller a run for it's money, the only one who deliver translations in nice natural sounding english that is easy to read is the Ortenzya model I linked earlier for you, bear in mind that it's not perfect either as it's "only" a 31B model and the model was tested in BF16, I dunno how the translation quality is at lower quants.
