What are Aphrodite Engine and ik_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

ik_llama.cpp

ik_llama.cpp is a fork of llama.cpp maintained by ikawrakow that adds optimized CPU and CUDA kernels, additional quantization formats, and improved performance for mixture-of-experts models. It targets users running large local models on commodity hardware.

  • New quantization types
  • Optimized MoE inference
  • CPU and CUDA kernels
  • OpenAI-compatible server
