LM Studio 0.3: built-in OpenAI-compatible server and multi-model management

LM Studio is a desktop app for downloading and running AI models locally. With version 0.3, it also becomes a server: you can start a local endpoint that mimics the OpenAI API, so any application written for GPT can use your local models. You can keep multiple models loaded at the same time and choose which one to use. HuggingFace downloads now show how much RAM or VRAM each model needs, so you can pick the right one for your computer.
