Depends on your VRAM or "unified" memory for how smart it is, and CPU/GPU for how quick it is.

128GB of RAM? Sure, the early to mid 4s releases, except maybe 4o. And on an M5 Max, about the same speed.

I wouldn't really bother under 64GB (meaning 32GB or less) except for entertainment value (chats, summaries, tasky read-only agent things).
