SOL-ExecBench is an nvidia benchmark for GPU kernel optimization toward hardware limits. Performance is measured as mean SOL (Speed Of Light) score across a set of kernels, where 1.0 represents optimal hardware utilization.
June 2026 Results
| System | Mean SOL (235 kernels) | Gap reduction |
|---|---|---|
| Previous leaderboard best | 0.699 | — |
| recursive automated system | 0.754 | 18% reduction in gap to 1.0 |
Recursive’s system invented new optimizations, recast known ideas under tighter constraints, and composed improvements across modeling and systems layers (2026-06-11-recursive-automated-ai-research).
