How to read this list
This is not a benchmark leaderboard. It is a routing chart for vibe coding: one-shot product work, supervised builds, specialist support, and cheap scaffolding.
Use A-tier for most supervised builds once the plan and acceptance criteria are clear.
Use B and C models when the task matches their narrow advantage: cost, local execution, X data, or ecosystem fit.
