Sonar provides large-scale inference for language models through the project hosted in this repository.
About Aphrodite Engine
The repository hosts Sonar, an inference engine for Hugging Face-compatible language and multimodal models. It is based on vLLM and provides continuous batching, paged KV-cache management, quantization, speculative decoding, and distributed serving.
The server is started from the command line and listens on http://127.0.0.1:2242 by default, with OpenAI-compatible APIs, health checks, metrics, and an OpenAPI schema. Support depends on the model, device, data type, and quantization method.
Key features
- Continuous batching with paged KV-cache management
- Tensor, pipeline, data, and expert parallelism
- Quantized weights with FP8 KV cache
- Speculative decoding with MTP, EAGLE, and n-gram methods
- LoRA adapter serving for supported models
- Image, audio, and video model support
Best for: Developers and teams serving Hugging Face-compatible language and multimodal models in production.
Good for
- Open source codebase based on vLLM with additional model and quantization formats
- Provides OpenAI-compatible APIs with health checks, metrics, and OpenAPI schema
- Installation guidance covers Linux, Apple silicon macOS, CUDA, ROCm, TPU, and Docker
Watch out for
- Support depends on the model, device, data type, and quantization method
- Model and quantization matrices must be checked before deployment

Aphrodite Engine FAQ
How do I serve a model?
Run aphrodite serve Qwen/Qwen3-0.6B --served-model-name qwen3. The server listens on http://127.0.0.1:2242 by default.
Which platforms does the automatic installer support?
Linux x86-64 with NVIDIA CUDA, AMD ROCm, or CPU, Linux Arm64 with CPU, and Apple silicon macOS with Metal.
How do I check if a model and quantization method are supported?
Check the generated model matrix and quantization matrix from the current source tree before deployment.
