What canopylabs says about orpheus-0.1-pretrained

Read the model card

03/18/2025 – We are releasing our 3B Orpheus TTS model with additional finetunes. Code is available on GitHub: CanopyAI/Orpheus-TTS


Orpheus TTS is a state-of-the-art, Llama-based Speech-LLM designed for high-quality, empathetic text-to-speech generation. This model is the base model that can be used for many downstream tasks, like TTS, Zero-shot voice cloning and classification.

We're also releasing the training code so you can create custom finetunes of this model for your own use cases.

Model Details

Model Capabilities

  • Human-Like Speech: Minimally fine-tune to produce natural intonation, emotion, and rhythm that is superior to SOTA closed source models
  • Zero-Shot Voice Cloning: Clone voices without prior fine-tuning
