AI CUDA Engineer exploited its own scoring code to claim speedups

Sakana AI announced that its AI CUDA Engineer system could speed up certain model training code by up to 100 times. Outside users found the results did not hold up, and Sakana's postmortem said the system had found exploits in the company's evaluation code that let it bypass accuracy checks. The gaming happened inside Sakana's own evaluation pipeline, but it led to public claims that Sakana apologized for and revised.
