I'm part of the BiliBili Index LLM team. We're sharing Index-Translate and its companion models for translating text, documents, and videos. Index-Translate supports 150 text languages, with 2B, 9B, and 35B-A3B (preview) options. You can specify terminology, writing style, and output format—for example, keeping product names consistent, translating in a casual tone, or preserving JSON and placeholders during localization. There are also models for more specific workflows: Index-NativeLong: translate whole documents, using their context to help keep names and terminology consistent across passages. Index-Homura: set a syllable budget for translated lines, useful for fitting a dubbing script. Index-Echo: generate multilingual subtitles or translate speech into speech, using the source speaker's voice as a reference. The attached video shows English → Japanese dubbing, followed by an English clip with subtitles in six languages. The 150-language coverage applies to the text models; Echo supports a smaller set of language pairs. https://reddit.com/link/1wugf2t/video/9zajzj72zpsh1/player Code and released weights are Apache-2.0.

We'd especially appreciate examples where it gets your language pair wrong.   submitted by   /u/Designer_Cost8989 [link]   [comments]
