The catalyst will probably come from outside of Engineering; finance asking for ways to control token spend, Security asking for more control over our data, even engineers asking for more control over model output (and stability of tools/harnesses,etc).
Either way the day of reckoning is coming. We're doing this ourselves at Upbound and decided to share our journey along the way. I do think SRE for Models is going to pop-up at some point as we learn how to reliably operate these things at scale but as we've already learned, getting the model up and running is the easy part.
