I haven't noticed a huge difference with other models but I agree that is definitely a strength (and CC has better tooling for this). However, I do think there are practical limitations to agentic workflows because of the relatively poor output vs humans. You can generate lots of code, but most of it will be shit.

Agentic workflows do have a place in well-defined, structured tasks...but I don't think that is what most people are trying to do with it.

...and codex is at least 10x better than Claude. I don't even bother starting a new session when working on a feature, a single compaction is basically unnoticeable. You have to compact several times to start needing to remind the model about a rule or two.
