Coding agent efficiency #
Our internal benchmark measures the cost efficiency of coding agents.
Methodology
It's built around two projects: Rain, a bespoke DSL written in Zig, and pgx, a real Postgres driver written in Go.
-
• Tasks cover features, bug fixes, and refactors in each project, meant to reflect a diversity of real world engineering work rather than intentionally tricky puzzles.
-
• There's 20 tasks, each run 5 times per agent for a total of 100 trials, measuring the score against total cost by token usage to determine performance per dollar.
