AI Overview
- Index-Translate from BiliBili's Index LLM team, built on Qwen3.5, comes in 2B, 9B, and 35B-A3B (preview) sizes covering 150 text languages, released under Apache-2.
- Users can specify terminology, writing style, and output format — e.g. keeping product names consistent or preserving JSON and placeholders during localization.
- Index-NativeLong translates whole documents, using passage context to keep names and terminology consistent.
- Index-Homura sets a syllable budget for translated lines, for fitting dubbing scripts.
- Index-Echo generates multilingual subtitles or speech-to-speech translation using the source speaker's voice; it supports fewer language pairs than the 150-language text models.
- A demo video shows English→Japanese dubbing and an English clip subtitled in six languages; code, weights, and a hosted demo are on GitHub and Hugging Face.
- Index-Translate outperforms same-size translation models and matches 100B-scale and frontier models on general translation and complex translation instructions.
- Index-Echo outperforms existing end-to-end speech translation models and matches frontier omni models on speech-to-text and speech-to-speech tasks.
