I think this is pretty big and cool. Check this out.

Simulating circuits is a - so to speak - old technology. But the hype is all this useless AI crap. Funny, right?

Got through the first 2 minutes of the video. The amp model sounds good.
This is a good example of “white box” modeling, meaning that it works by modeling all of the individual components in the amp’s circuit from input to output. Line 6 says their new Agoura modeling uses this method.
White box modeling is ultimately only as good as the models of those individual components. There’s more to the behavior of a capacitor than formulas for charging and discharging. Likewise, there’s more to the behavior of diodes, transistors of all types, transformers, and even resistors, than their common math dictates at a circuit analysis level. A good SPICE model should take all of these tiny parameters into account for each component.
Neural DSP does “black box” modeling, meaning that they send an input into a device and measure the response of the output. Doug mentioned in that recent Rick Beato interview that the goal is to capture all of the little nuances and idiosyncrasies of a device’s performance; real amplifiers, distortion pedals, and now compressors and fuzz pedals with the new V2 tech. There may be weird quirks that happen in the physical world that just aren’t modeled accurately purely by software. (You’d be surprised at how much semiconductors alone are affected by temperature.)
One approach is not inherently better than another, though proponents of white box modeling tend to talk louder about it being superior. The tech is improving everywhere and we’re getting better and better modeling all the time. As they say, “A rising tide helps all ships float.” Kudos to this guy for figuring it out and building his own plug-in.
