Also tried it on a small project, it did ok finding issues but completely failed doing rather basic edits, like it lost closing brackets or used wrong syntax and couldn't recover. The CLI was easy to setup and use though.
Back when Devstral 1 released, this was made very noticeable to me because the ones who used the smaller quantizations were unable to actually properly format the code, just as you noticed, that's why this sounded so similar to what I've seen before.
