The models are pretty much the same, the differentiation for the last few months have purely been in the tooling and harness around the models.

As it will continue to be. Unless we get a Opus-5 or GPT-6 that blows everything out of the water, all major progress will be in the UX/DX of the tools and what tools each harness will let the agent use and how.

For now Claude is the best at this, MS is trying to keep up with Copilot in VSCode and Codex ... exists.
