What is the best computer for running AI agents?
Cloud-based agents
If your agent sends its work to a hosted model, the computer mainly runs your code, a browser or tools, and network requests. A modest machine works well here, including a basic laptop, a small mini PC, or a low-cost cloud server. A stable connection and uptime often matter more than raw speed.
Local models
Running models on your own hardware needs enough memory to hold the model weights, either in system RAM or graphics memory. Smaller models can run on machines with 16GB of memory, while larger ones usually need 32GB or more. Apple Silicon Macs with unified memory and PCs with a recent dedicated GPU are common choices.
Speed depends heavily on the chip and the model size. Test a model on your machine before you commit to a purchase, and check current hardware reviews and model requirements.
- 16GB RAM: fine for cloud agents and small local models
- 32GB or more: better for larger local models
- A dedicated GPU with plenty of video memory speeds up local inference
- A fast SSD loads model files more quickly
- A mini PC can run an agent around the clock with low power use
Common mistakes
- Buying expensive hardware for an agent that only calls a hosted API.
- Choosing a model too big for your memory, then blaming the agent for slow responses.
