Ollama vs LM Studio: Which AI Tool Is Right for Your Hardware?
Side-by-side comparison of local model support, GPU requirements, OpenRouter compatibility, pricing, and setup difficulty. Find which tool fits your workflow and hardware.
Ollama
The industry standard for running LLMs locally. Simple CLI, massive model library (100K+), OpenAI-compatible API on port 11434. Powers Open WebUI, Continue, and more.
LM Studio
Desktop app for running local LLMs with zero setup. In-app model browser, visual GPU fit indicator, and one-click GGUF downloads from Hugging Face.

Which should you choose?
Choose Ollama if
- Running LLMs locally as a backend for other apps
- Local API server for development (drop-in OpenAI replacement)
- Quick model testing via CLI
- You prefer open source
- You need local model support
Choose LM Studio if
- Easiest way to run LLMs locally without CLI
- Testing models before deploying (visual fit indicator)
- Offline AI chat — no internet needed after downloading models
Hardware requirements
Ollama
No GPU required — runs on CPU for small models (3B-8B) with sufficient system RAM. For 7B models, 8 GB VRAM recommended for usable speeds. Default context window is only 2K — increase it for coding agents.
LM Studio
4 GB+ VRAM minimum. 8 GB VRAM recommended for usable speeds with 7B models. Apple Silicon Macs with 16 GB+ unified memory run very well via Metal acceleration. CPU-only works but is 5-10x slower for 7B+ models.
