description Overview

vLLM (API Serving)

vLLM is primarily known for its high-throughput serving capabilities, utilizing advanced techniques like PagedAttention. While it's often used for cloud deployment, running it locally allows developers to simulate production API endpoints with superior batching and request handling. It's ideal when your local setup needs to handle multiple concurrent requests or simulate a robust backend service.

LM Studio (Local Model Runner)

LM Studio is not an IDE plugin, but it is the single most crucial tool for accessing local models. It provides a user-friendly GUI to download, manage, and run quantized models (GGUF format) from various sources. Its local API server capability makes it an excellent backend for connecting to IDE plugins like Continue, democratizing access to powerful, private LLMs.
