Orpheus-3b-German-FT-Q8_0

This is a quantised version of canopylabs/3b-de-ft-research_release.

Orpheus is a high-performance Text-to-Speech model fine-tuned for natural, emotional speech synthesis. This repository hosts the 8-bit quantised version of the 3B parameter model, optimised for efficiency while maintaining high-quality output.

Model Description

Orpheus-3b-FT-Q8_0 is a 3 billion parameter Text-to-Speech model that converts text inputs into natural-sounding speech with support for multiple voices and emotional expressions. The model has been quantised to 8-bit (Q8_0) format for efficient inference, making it accessible on consumer hardware.

Key features:

• 3 distinct voice options with different characteristics
• Support for emotion tags like laughter, sighs, etc.
• Optimised for CUDA acceleration on RTX GPUs
• Produces high-quality 24kHz mono audio
• Fine-tuned for conversational naturalness

How to Use

This model is designed to be used with an LLM inference server that connects to the Orpheus-FastAPI frontend, which provides both a web UI and OpenAI-compatible API endpoints.

Compatible Inference Servers

This quantised model can be loaded into any of these LLM inference servers:

• GPUStack - GPU optimised LLM inference server (My pick) - supports LAN/WAN tensor split parallelisation
• LM Studio - Load the GGUF model and start the local server
• llama.cpp server - Run with the appropriate model parameters
• Any compatible OpenAI API-compatible server

Quick Start

1. Download this quantised model from lex-au's Orpheus-FASTAPI collection

2. Load the model in your preferred inference server and start the server.

3. Clone the Orpheus-FastAPI repository:

git clone https://github.com/Lex-au/Orpheus-FastAPI.git
cd Orpheus-FastAPI

1. Configure the FastAPI server to connect to your inference server by setting the ORPHEUS_API_URL environment variable.

2. Follow the complete installation and setup instructions in the repository README.

Available Voices

The model supports 3 different voices:

• Jana: Female, German, clear
• Thomas: Male, German, authoritative
• Max: Male, German, energetic

Emotion Tags

You can add expressiveness to speech by inserting tags:

• <laugh>, <chuckle>: For laughter sounds
• <sigh>: For sighing sounds
• <cough>, <sniffle>: For subtle interruptions
• <groan>, <yawn>, <gasp>: For additional emotional expression

Technical Specifications

• Architecture: Specialised token-to-audio sequence model
• Parameters: ~3 billion
• Quantisation: 8-bit (GGUF Q8_0 format)
• Audio Sample Rate: 24kHz
• Input: Text with optional voice selection and emotion tags
• Output: High-quality WAV audio
• Language: German
• Hardware Requirements: CUDA-compatible GPU (recommended: RTX series)
• Integration Method: External LLM inference server + Orpheus-FastAPI frontend

Limitations

• Best performance achieved on CUDA-compatible GPUs
• Generation speed depends on GPU capability
