# Magnitude: A coding agent that runs on open models > Source: > Published: 2026-06-20 17:35:21+00:00 # Frontier coding without frontier prices Magnitude is a coding agent that runs entirely on open models. It costs 60% less than Claude Code with no drop in performance. Pass-through API pricing with no markup. $5 free credits. ## Smart model routing "I need to explore the codebase, plan the implementation, then implement and review." "Explore existing middleware patterns" "Design auth strategy" "Add JWT middleware + routes" "Review the changes" "Explore existing middleware patterns" "Design auth strategy" "Add JWT middleware + routes" "Review the changes" A strong leader model plans and coordinates the work, routing subtasks to lower-cost specialists for 50–90% cost savings without sacrificing performance. ## 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](https://github.com/jackc/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. ## We'll build what your team needs Tell us your requirements and we'll deliver a tailored setup. - ### Self-hosted open models We'll help you run open models on whichever infrastructure you prefer. - ### Custom model configurations Tailored model setups for your team's workflow and requirements. - ### Team controls Shared billing, spend limits, and admin tools for your organization.
