Mac mini for AI agents: how much memory you need and how to get more from your current machine

Measure what your agents actually use before buying hardware; improve memory, storage, and workload scheduling first.

Published

AI agents consume more than model inference: browsers, development servers, caches, dependencies, and temporary files can keep using a computer long after a task appears finished. Before replacing your machine, inspect memory pressure and identify the processes and directories responsible.

Ask an agent to produce a read-only inventory first. Once you understand the workload, shut down unneeded services, give each agent a clear stopping condition, and store outputs predictably. Run heavy work in stages, increasing concurrency only after measuring the impact.

As a broad starting point, 24–32 GB of memory can suit everyday use that combines apps and agents; 16 GB can work with more active management. Local models, long contexts, and parallel requests change the requirement substantially. An older computer may provide useful separate capacity instead of being discarded.

The right purchase depends on the work you actually run. Auditing, process hygiene, and ongoing maintenance matter as much as processor choice.
