What are exo and MLC LLM?
exo
exo is an open-source project that unifies multiple everyday devices into a single AI compute cluster for running large language models. It splits models across phones, laptops, and desktops and exposes an OpenAI-compatible API.
- Distributes models across devices
- OpenAI-compatible API
- Automatic device discovery
- No master node required
MLC LLM
MLC LLM is a machine learning compiler and runtime that deploys language models natively across GPUs, CPUs, browsers, and mobile devices. It enables high-performance self-hosted inference on diverse hardware.
- Compile models for any hardware
- Native GPU acceleration
- Browser and mobile runtimes
- OpenAI-compatible serving
