Usage

import { VectrionRouter } from "@vectrion/router";
import { Vectrion } from "@vectrion/core";

// Cheapest-first routing — picks the lowest cost provider
const ai = new Vectrion({
    providers: [googleAdapter, ollamaAdapter],
    router: new VectrionRouter({ strategy: "cheapest" }),
});

// Fallback routing — tries providers in order until one succeeds
const ai2 = new Vectrion({
    providers: [googleAdapter, ollamaAdapter],
    router: new VectrionRouter({
        strategy: "fallback",
        fallback: ["google", "ollama"],
    }),
});

Strategies

| Strategy | Description | | ---------- | --------------------------------------------------------- | | cheapest | Routes to the provider with the lowest cost per token | | fallback | Tries providers in specified order, falls back on failure |
