For agentic work, you just cache the prefill kv cache of the relevant system prompts. TTFT is a little slow (10s of seconds, oh no!) the first time you boot up a new harness.
I keep hearing people make this claim that TTFT is a problem, and… it just isn’t, if you’re running oMLX.
Folks in my camp keep saying this, and folks in your camp keep beating a drum we tell you isn’t resonating. Not sure why I keep bothering to argue; you can’t buy a high RAM Mac Studio like mine anymore.
