This enterprise client helps the world’s most innovative companies improve their AI models by providing human feedback.  Help build a benchmark of real, expert-level problems that today’s best AI agents still can’t solve. Experts take a genuinely hard problem from their own field and turn it into a task an AI must solve from scratch in a Linux terminal. The goal: stump the model. A task counts only if, when three frontier AI models each try it three times, they mostly fail. It’s not annotation — contributors design the problems that expose where AI still breaks.
