What LLM runs on an M4 Max with 64GB?

For everyday chat at 8K context, this page applies the Local Lab planner to Apple's reported 64GB M4 Max unified-memory configuration. Fit is calculated; it is not an observed Mac benchmark.

DIRECT ANSWER

Qwen3.6-27B, Qwen3.8-27B and Gemma 4 31B-it

These are the leading calculated memory-fit recommendations for a Mac Studio M4 Max with 64GB unified memory in Kingy's current verified 12-model catalogue. This is not a universal model-quality leaderboard.

Apple evidence boundary: every M4 Max result below is calculated from unified-memory capacity. Kingy has no observed M4 Max run receipt; any linked owned-hardware evidence comes from an RTX 4090.
