Can I run xor on a Mac with 64 GB?

Probably, at 4-bit

The published weights are too big, but a 4-bit version (about 19.7 GB) would fit, with room for ≈ 256K tokens of context. The site hasn't analyzed a GGUF of xor yet.

Assumes 75% of the Mac's memory is usable (macOS's default limit for the GPU; it can be raised) and at least 4K tokens of context for one conversation, with the context cache in 16-bit unless noted. Fits leaves at least 20% of that memory for context; Tight leaves less.
