Can I run Naive-N0.5-Flash on a Mac with 256 GB?

Probably, at 4-bit

The published weights are too big, but a 4-bit version (about 174 GB) would fit, with room for ≈ 121K tokens of context. The site hasn't analyzed a GGUF of Naive-N0.5-Flash yet.

Each file of Naive-N0.5-Flash (and of GGUF versions the site has analyzed), and how much context fits next to it, with the context cache in 16-bit or 8-bit.

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.
