What are llama.cpp and Petals?

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

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
