System-level intelligence

Signal
before scale

Built on Shannon signals, entropy folding, and neural-symbolic routing.

抢先体验 Open white paper

A router should feel like a system brain: encoder-guided, entropy-aware, and ruthlessly clear.

Signals13

13 signal families spanning intent, safety, modality, context, and preference.

Selection12

12 selectors across symbolic policy, latency heuristics, reinforcement learning, and ML routing.

Surfaces03

One architecture across cpu-local, amd-local, and ci-k8s.

Quick start

One supported local path. Copy the installer, run it, then open the dashboard.

Install locally in one line.

The supported first-run path is a single installer that sets up the CLI and local serve flow on macOS and Linux.

One-liner installmacOS / Linux

curl -fsSL https://vllm-semantic-router.com/zh-Hans/install.sh | bash

Installs into ~/.local/share/vllm-sr, writes ~/.local/bin/vllm-sr, and keeps Windows on the manual pip flow in the docs.

Full installation guide

Core logic

Neural-symbolic routing, kept legible.

Encoder priors, Shannon mapping, entropy folding, and model selection stay visible from research prototypes to production paths.

Signal extraction

Encoder signals turn raw requests into legible semantic state.

Decision engine

Neural signals meet symbolic rules in auditable routing logic.

Plugin chain

Cache, safety, rewrite, and tracing attach as composable behaviors.

Intent-to-policy compile

Natural language intent compiles into neural-symbolic policy before execution begins.

Research-grade model selection

Selection stays measurable enough for papers, benchmarks, and production tuning.

System docs

Docs, papers, and product routes read as one system, not scattered collateral.
