SkySynth co-evolves proofs and tests with code: KV stores 2.3x faster than Redis, inference 2.2x vLLM
abeirami · x · 2026-09-12
shulynnliu's team released SkySynth, an engine for synthesizing high-performance, just-in-time (JIT) systems that can be trusted, by co-evolving formal proofs and tests alongside agent-generated code—addressing the core question of whether we can trust what agents build.
Reported results:
- KV stores up to 2.3x faster than Redis and FASTER, with formally verified stores achieving 2.9x Claude Code's pass rate.
- Model routers up to 48% cheaper than a general router.
- A specialized inference engine with 2.2x the throughput of vLLM/SGLang.
Commenters note verification is the make-or-break of evolving agents, and this work offers a concrete answer.
