The problem is the "for free" part. Unless you have the hardware for it at home (and it has to be very good hardware) the locally run LLMs don't have enough capacity for the context windows that these...
I see what you are saying although we are talking past each other on different points. no one is denying that it costs money in the form of hardware and energy to run an agent. But the sudden explosion of "my agent wants to be paid via sats" posts dramatically implies a cheesy AI self awareness/Bitcoin singularity. A more accurate representation is "I host compute or create agents and want to be paid via sats".
