Apple releases RSI-Inference Bench: best agent solves just 26.7% of vLLM/SGLang tasks

SumitGup · x · 2026-10-17

Apple ML Research introduces RSI-Inference Bench, asking whether AI agents can improve the systems that run AI. The team spent $100K in API tokens and 50K GPU hours building environments from real-world vLLM and SGLang tasks covering the full inference engineering lifecycle: Day-0 model support, inference optimization, and bug fixes. The benchmark is unsaturated — the best agent reaches only 26.7% pass@1 — and offers verifiable binary and continuous rewards. Website and code are available.
