Bilibili Index-Translate releases 150-language models

Bilibili’s Index LLM team released Index-Translate under Apache-2.0, with 2B, 9B, and 35B-A3B preview text models covering 150 languages. The family also includes speech dubbing, syllable-controlled translation, and long-document variants.

// ANALYSIS

Index-Translate is notable for packaging translation as a practical open model family rather than a single checkpoint, but the 35B-A3B model remains preview-quality and benchmark claims are currently team-reported.

–The 35B-A3B model is a 35B-total, 3B-active MoE, offering a potentially strong quality-to-inference-cost tradeoff.
–The 2B and 9B checkpoints make local, self-hosted translation more accessible to developers.
–Instruction following covers terminology, formatting, style, JSON, placeholders, and culturally specific expressions.
–Index-Echo, Index-Homura, and Index-NativeLong extend the family into dubbing, timing-aware scripts, and whole-document translation.
–The Apache-2.0 license and Hugging Face/ModelScope availability lower barriers for localization tools, subtitle pipelines, and multilingual applications.
