I'm also very excited by the different shapes for solving problems in this space. A little worried that the path dependence is ACTUALLY a bit warranted since "popular harness engineering is just claude-wrapping" is a bit of a self-fulfilling prophecy today.

I've heard many claims that because LLMs are tuned to specific harnesses, we should expect worse performance with novel architectures. That seems to make people reluctant to try to put effort into inventing them.
