mr opus says wait (for the 512GB mac studio)...
‘The 512 config lets you run a big model and a deep context, which for agentic coding is usually the binding constraint.
If your target is GLM-5.2-class models at 4-bit with real context, or local fine-tuning, the 512 is the whole point and worth waiting until late October.’
