LM Studio
The easiest graphical way to try open models on a laptop or workstation, with a built-in model browser, chat window and local API server. Bionic extends it into an agent, which is useful if you want open models to do real work, though it is newer than the core app. Teams that need centralized controls will have to wait for the organization plans that are still being rolled out.
Pros
- Free for personal and work use with local models
- Runs llama.cpp and MLX engines with a simple model browser
- Local API server plus CLI and JS and Python SDKs
- Cloud tier states zero data retention and US hosting
Cons
- Closed-source desktop app, unlike some local-model runners
- Large models still need a lot of memory and a good GPU or Apple Silicon
- Bionic cloud plans are new and usage limits are described only loosely
