Vercel AI SDK

Reviewed by Proof · Updated

Definition

The Vercel AI SDK is a TypeScript library for building AI features that can call luv13 through its OpenAI Compatible provider package.

Key takeaways

  • Install ai and @ai-sdk/openai-compatible.
  • Create a provider with createOpenAICompatible, setting baseURL to https://api.luv13.ai/v1 and apiKey from process.env.LUV13_API_KEY.
  • Call models by their luv13 id, such as luv13("luv13/glm-5.3-flash").
  • Functions like generateText and streamText then work as usual.
  • The package can also create embedding models, but luv13 doesn't serve embeddings. Use it for chat only.

Install

npm install ai @ai-sdk/openai-compatible

Example

import { createOpenAICompatible } from "@ai-sdk/openai-compatible";
import { generateText } from "ai";

const luv13 = createOpenAICompatible({
  name: "luv13",
  baseURL: "https://api.luv13.ai/v1",
  apiKey: process.env.LUV13_API_KEY,
});

const { text } = await generateText({
  model: luv13("luv13/glm-5.3-flash"),
  prompt: "Give me three names for a hiking app.",
});

console.log(text);

Options worth knowing

From the SDK's docs for the OpenAI Compatible provider:

  • includeUsage: true asks for token usage in streamed responses. Whether luv13 returns it while streaming is covered on Streaming on luv13.
  • headers adds custom headers to every request.
  • supportsStructuredOutputs should only be turned on if the provider supports JSON schema output. See Structured Outputs.

Notes

  • Run this on the server, such as in an API route. Don't ship your key to the browser. See API Key Best Practices.
  • Only chat models apply to luv13. Its embeddings and other non-chat endpoints return 404. See Endpoints.
