What are Aphrodite Engine and llama.cpp?

Aphrodite Engine

Aphrodite Engine is the official backend serving engine for PygmalionAI, optimized for high-throughput LLM inference. It exposes an OpenAI-compatible API and supports a wide range of quantization formats.

  • High-throughput batching
  • OpenAI-compatible endpoints
  • Many quantization formats
  • Continuous batching

llama.cpp

llama.cpp is a C/C++ inference engine for running LLaMA-family and many other models efficiently on CPUs and GPUs. It pioneered the GGUF quantized model format and powers a large portion of the local-AI ecosystem.

  • GGUF quantization
  • Runs on modest hardware
  • Built-in HTTP server
  • Broad GPU backend support
