M5 Ultra Mac Studio Review: The Dream Mac for Local AI Agents - MacStories

The M5 Ultra Mac Studio with 256 GB of RAM is reviewed as a dream machine for local AI agents. The author tested various cloud providers like Inco, Cerebras, Fireworks, and Baseten for AI tasks, noting their high performance (e.g., Kimi K3 at 300 TPS, Qwen3.8-27B at 1,800 TPS) but also their cost and data privacy concerns. The M5 Ultra Mac Studio allows for local execution of AI agents using Open Minis and Apple CLIs, ensuring data remains on the user's device.
