I've not spent enough time with Mistral Vibe yet for a credible comparison, but given what I know about the underlying models (likely-1T-plus Opus 4.5 compared to the 123B Devstral 2) I'd be shocked if Vibe could out-perform Claude Code for the kinds of things I'm using it for.

Here's n example of the kinds of things I do with Claude Code now: https://gistpreview.github.io/?b64d5ee40439877eee7c224539452... - that one involved several from-scratch rewrites of the history of an entire Git repo just because I felt like it.
