What are Aphrodite Engine and Petals?

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

Petals

Petals lets you run and fine-tune large language models in a distributed, BitTorrent-style network where each participant hosts part of the model. It enables self-hosting models too large for a single machine.

  • Distributed model hosting
  • Run models larger than one GPU
  • Collaborative inference swarm
  • Fine-tuning support
