Own your intelligence stack, folks!
I will never get tired of saying this. Your business's very existence is at play here.
But you don't have to do this all at once if you can't afford it. I mean, open models are still very expensive to run and tune.
If you want to start somewhere, I suggest the harness. Build your evals and quickly move down the stack.
The great part about building your own harness is that it gives you optionality, unlocks capabilities, and helps you measure where else in the intelligence stack you need to invest next.
So while open-source was an alternative in the old era, today it is how you survive and thrive in the age of intelligence.
