I think of them as different people -- I'll say that I use them in "ensemble mode" for coding, the workflow is Claude 3.5 by default -- when Claude is spinning, o1-preview to discuss, Claude to implement. Worst case o1-preview to implement, although I think its natural coding style is slightly better than Claude's. The speed difference isn't worth it.
The intersection of problems I have where both have trouble is pretty small. If this closes the gap even more, that's great. That said, I'm curious to try this out -- the ways in which o1-preview fails are a bit different than prior gpt-line LLMs, and I'm curious how it will feel on the ground.
