SkySynth synthesizes formally verified systems: KV stores 2.3x faster than Redis

CShorten30 · x · 2026-09-14

SkySynth is an engine for synthesizing high-performance, just-in-time (JIT) systems that can be trusted, by co-evolving formal proofs and tests alongside the code generated by coding agents.

Results: KV stores up to 2.3x faster than Redis and FASTER with formally verified variants at 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. Available as a plugin for Claude Code and Codex, letting anyone specialize systems to their own workload and hardware.
