Vals AI CEO Rayan Krishnan on why defensible evals are critical for enterprises' survival: "The labs side of it is very clear. If you're raising lots of money, investing heavily in building models, it's essential for you to show why your model is getting better and why the customer should pay a premium for them." "But what I think is still underappreciated is, on the enterprise side, this is turning out to be existential as well." "We're in this world where it is still very unclear what ROI looks like and how to value this intelligence that's being used... Token spend may start to eclipse salary spend." "If this is such a meaningful line item in your costs, you have to justify the ROI much more cleanly... Over time, I think a firm really is just its evals." "The ability for a company to make its evals legible in order to solve this ROI calculus is going to be the reason why that company wins out over its competitors in the long term." @RayanKrishnan @eriktorenberg(a16z)
