Labs are now post-training models with Harness so that Harness now gets absorbed into the weights.

I’d say that harnesses almost by definition are the parts that you want to keep customizable. That won’t get absorbed into the weights.

		Depends on your product strategy. If you only care about how your model will be used in the context of a harness (perhaps, specifically the harness that you designed), then the incentive is plainly there to optimize the weights within the context of the harness.

My naive intuition is that as harnesses converge on shape and models improve the first party advantage will mostly disappear.
