One AI SDK provider for the whole catalog

What this is for

Vercel AI SDK providers are usually one-vendor. Switching models should not mean a new client or a new key.

Steps, then copy

1. 1.npm install @anyr/ai-sdk-provider ai
2. 2.createAnyRouter() reads ANYROUTER_API_KEY when you omit the key.
3. 3.Call anyrouter("anyrouter/free") or anyrouter("anyrouter/auto").

import { createAnyRouter } from "@anyr/ai-sdk-provider"
import { generateText } from "ai"

const anyrouter = createAnyRouter()

const { text } = await generateText({
  model: anyrouter("anyrouter/free"),
  prompt: "What is AnyRouter?",
})
console.log(text)

Next playbooks

• Keep the OpenAI SDK, change two fieldsOverride baseURL and apiKey. Model ids are owner/model strings across 271+ models.
• Start on anyrouter/free or anyrouter/autoTwo built-in virtual models: free failover on every plan (anyrouter/free) and stable paid failover (anyrouter/auto). Do not pick a flaky SKU for your first request.
• One API in front of every provider dialectOpenAI /chat/completions, Anthropic /messages, and a Responses API — same key, same catalog.
