Index-Translate is a family of multilingual translation models built on Qwen3.5. The text models cover 150 languages and follow translation instructions such as terminology, formatting, and content-preservation requirements. The family extends this foundation to speech, syllable-controlled translation, and full-document translation.

-Index-Translate translates text, structured content, and community expressions.
-Index-Echo produces translated subtitles or speech conditioned on the source speaker's voice.
-Index-Homura adjusts translations toward a specified target syllable count.
-Index-NativeLong translates complete documents with context across passages.
