post training is both the future and the secret sauce.

The next iteration of AI assisted devs will not have all the devs use the same harness and model like most do now.

Instead, devs will build their own post trained models that are experts of their own domain, that have their secret sauce..

I imagine any dev would want most of those models to be something they can self host because of multiple reasons - one of them being that their employers or customers might not agree to use a cloud hosted or managed model. Plus, costs. And control.

Post training is in the future because we haven't yet reached a shared agreement on what that first "good enough" model will be like - and also because the current AI scape is in a state of flux where post training will have a lot of churn.
