BENCHMARKS

We cost 60% less than Claude Code with no drop in performance

Our internal benchmark measures the cost efficiency of coding agents.

Coding agent efficiency benchmark results

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.

HOW IT WORKS

Smart model routing

User: "Add authentication to the API"

Leader GLM 5.2

"I need to explore the codebase, plan the implementation, then implement and review."

A strong leader model plans and coordinates the work, routing subtasks to lower-cost specialists for 50–90% cost savings without sacrificing performance.
