GLM-5.3 would be bottlenecked by the M5's GPU, here. I don't have any hard numbers, but Apple Silicon is known for weak prefill performance on larger models (yes, even MoEs).
Good to know. Private GLM-5.3 is really the one use-case I can imagine for a system like this - It does very well with cybersecurity tasks, which are either blocked for most people by current providers, or on their way to getting blocked based on the regulatory/political trends. Such a capability could become very valuable when supply becomes artificially limited, although I expect the Chinese labs will be the last hold-outs. Imagine not being able to do security hardening on your own tech because government-imposed guardrails decide your legitimate prompts appear "risky". In such a world, what would an unconstrained cyber-capable model be worth?
