LOCAL AI SOFTWARE

Ollama vs LM Studio

Both run downloadable AI models locally. Ollama is especially attractive as a lightweight runtime and API; LM Studio puts model discovery, loading and chat into a desktop graphical app.

Choose Ollama when the runtime is the centre

Ollama is a natural fit when other software needs to call a local model or when you plan to pair it with Open WebUI.

Choose LM Studio when you want a desktop workspace

LM Studio lets you search for models, download them, load them into memory and chat in one app. It can also serve local models through API endpoints.

Hardware support differs

LM Studio currently supports Apple Silicon Macs, Windows x64 and ARM systems, and Linux x64/ARM64. Its current requirements recommend 16 GB or more RAM, and on Windows recommend at least 4 GB dedicated VRAM.

The model still matters more than the app

Compare the same model, quantisation and context when judging memory or speed.

Next: work out how much VRAM you need or use the memory calculator.
