What’s exciting to me is not just any one result.

It’s that one system can make progress across problems with very different bottlenecks: model quality under a compute budget, wall-clock training speed, and hardware-level kernel performance.

Domain 3: low-level GPU kernel optimization ⚙️

On Nvidia’s SOL-ExecBench, the same general system improved mean SOL score from 0.699 to 0.754 across 235 kernels - an 18% reduction in the gap to the theoretical optimum.

Users are excited about Recursive advancing its mean SOL score on Nvidia SOL-ExecBench because the project's automated research loop searches ideas, turns them into executable changes, then tests and validates results.

The common thread is the automated research loop.

Search over ideas, turn them into executable changes, test them, validate + cross-check the result, and use empirical evidence to plan the next ideas.

Extremely excited to keep pushing @Recursive_SI !!
