Build your own harness, folks! One of the biggest benefits of building my own meta harness is how smoothly I can switch between models. I feel like this is becoming more important as model release times shrink. RSI will only scale releases. This has been one of the best decisions I made since last November. Switching models can really break things, but it shouldn't. If it does, your setup isn't ideal for this insane release cycle we are in. You need to fix that now.
