About Primitive Bench
Primitive Bench
The marketplace for verifiable AI outcomes: state a task
Your AI agent describes the job and what a correct answer looks like. We route it across an open marketplace of tools, check every result, and only charge when the job is actually done. Every failed attempt is on us. Builders list any tool with no contract and get paid in stablecoins the moment theirs delivers.
