I do! I have an M3 Ultra with 512GB. A couple of opencode sessions running work well. Currently running GML 4.7 but was on Kimi K2.5. Both great. Excited for more efficiencies to make their way to LLMs in general.
The prompt processing times I've heard about have put me off wanting to go that high with memory on the M series (hoping that changes for the M5 series though). What's the average and longest times you've had to wait when using opencode? Has any improvements to mlx helped in that regard?
The M5 ultra series is supposed to have some big gains around prompt processing - something like 3-4x from what I've read. I'm tempted to swap out my m4 mini that I'm using for this kind of stuff right now!
