AutoTuring gives the same tuning AI agentAn AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.Full definition → the identical 15-dimensional accelerator design space twice -- once with named architectural knobs, once as anonymous [0,1] numbers -- isolating whether understanding the problem's meaning actually helps.
With meaningful framing, the agent beat a modeled H200 by 5.4% and beat its own 'blind' version by 12.3% on average, while needing 70.1% fewer simulator calls.
Adding a critic loop (structured self-critique) closed most of that gap for the blind agent but gave the meaning-aware agent nothing extra -- suggesting architectural knowledge and structured critique substitute for each other rather than stacking.
The authors flag this as preliminary: five to six runs per condition on a single modeled accelerator, with the comparison method itself, not the accelerator design, as the contribution.
