Even with the price hike, Deepseek V4 Flash still does this a lot better than any similarly priced model, in my experience. I've had Luna take shortcuts (like adding an overload to methods whose signature it changed so they don't break existing tests, instead of fixing the tests) or just not do the entire work and report it as done (did not fully resolve rebase conflicts). Deepseek has never really failed in this type of way for me, and it has been far more persistent in validating its work than Luna (and several bigger models).
