Mac Studio Ultra 192GB for local AI — can you actually tell the difference vs Claude Opus for browser automation?
Currently using OpenClaw with Claude Opus 4.7 for browser automation workflows — pulling listings, researching properties, drafting documents, running multi-step agent tasks. Paying $280/month between Claude and Codex subscriptions.
Seriously considering a Mac Studio M4 Ultra 192GB to run local AI and cut that bill down. From everything I've read, the best local setup gets you to roughly 85% of cloud quality.
My main questions for anyone who's actually run both side by side:
- For routine browser automation (multi-step tasks, form filling, research workflows) — is the gap noticeable day to day?
- Where does local actually fall short vs Opus in your experience?
- Is the 192GB worth the $7k or does the $3,999 128GB Studio cover most of the same ground?
Not a developer, more of a power user running automated real estate workflows. Privacy is a plus but mainly trying to figure out if the quality drop is something I'd feel constantly or just on edge cases.
