The models are good enough these days that I see it like managing a team of juniors. The LLMs need guidance and oversight, and about the same amount of time I'd spend reviewing code from a junior I spend on the LLM output. I think generally it's best practice to work in a way that "commit and hope it works (because it passes all the CI/CD automated testing and verification, and it's a change gated behind feature flags and has an identified and minimal blast radius, etc)" is possible
