Description
Most LLM routers are Python wrappers or cloud proxies that add tens of milliseconds before a request reaches the model. Jev-router is an in-process, zero-allocation native Rust engine that classifies and assigns routes in under 5 ms. Its deterministic fallback cascade uses byte-level automata, subword classifiers, and closed-form evaluators before escalating to an embedding model or LLM. Simple requests are resolved locally, without touching either.

Could you build this?
No High-performance systems programming in Rust involving sub-5ms zero-allocation routing, byte-level automata, and custom tokenizer cascades cannot be vibed without deep systems engineering expertise.
What it would actually take: A real version requires an in-process native Rust library utilizing deterministic finite automata (DFA), SIMD optimizations, and zero-copy byte parsing. It requires deep knowledge of compiler optimizations, memory layout, memory-mapped models, and formal language theory to achieve sub-5ms classification without memory allocations. Testing and benchmarking require rigorous microarchitectural profiling (perf, flamegraphs).
