This is clearest reason for us to accustom ourselves to using open weight models on open source harnesses. Whatever advantages the frontier closed models offer, this will turn into ash in the mouth, when the enshittification cycle begins. And don't be mistaken, it will begin. There is no precedent which can claim otherwise.

I am sure the models themselves are being RLHF tuned to work very well with the proprietary agent harnesses. This is all turning into a huge trap right in front of our eyes and the target is not just programmers but also companies whose core product involves software production.
