This model is not currently supported on Together AI.

Visit our Models page to view all the latest models.

Rime Arcana V3 supports 11 languages with native code-switching that preserves prosody and accent consistency across language boundaries. When customers switch from French to English for technical terms, then back to French for clarification, V3 handles these transitions while maintaining natural cadence and emphasis—so the conversation doesn't sound stitched together. Teams consolidate what used to require separate models or vendors per language into a single endpoint serving multilingual customers, with co-located deployment alongside LLM and STT workloads on Together AI's production infrastructure.
