Vercel AI SDK - RedPill AI

Use the AI SDK’s OpenAI-compatible provider with RedPill.

npm install ai @ai-sdk/openai-compatible
export REDPILL_AI_API_KEY="YOUR_API_KEY"

Configure the provider

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

const apiKey = process.env.REDPILL_AI_API_KEY;
if (!apiKey) throw new Error("REDPILL_AI_API_KEY is required");

export const redpill = createOpenAICompatible({
  name: "redpill",
  apiKey,
  baseURL: "https://api.redpill.ai/v1",
});

Use .chatModel() with an exact model ID. The provider sends that ID without adding a prefix.

Generate text

import { generateText } from "ai";

import { redpill } from "./redpill";

const { text } = await generateText({
  model: redpill.chatModel("z-ai/glm-5.2"),
  prompt: "Explain attestation in one sentence.",
});
console.log(text);

Stream from a route

app/api/generate/route.ts

import { streamText } from "ai";

import { redpill } from "../../../redpill";

export async function POST(request: Request) {
  const body: unknown = await request.json().catch(() => null);
  if (
    typeof body !== "object" ||
    body === null ||
    !("prompt" in body) ||
    typeof body.prompt !== "string" ||
    body.prompt.trim().length === 0
  ) {
    return Response.json({ error: "A non-empty prompt is required" }, { status: 400 });
  }

  const result = streamText({
    model: redpill.chatModel("z-ai/glm-5.2"),
    prompt: body.prompt.trim(),
  });
  return result.toTextStreamResponse();
}

Keep the RedPill key on the server. Validate tool arguments and bound multi-step tool loops.

Verification boundary

The base-URL configuration does not verify ACI locally. Node and Bun applications can pass connectAci().fetch to createOpenAICompatible, then audit the retained receipt after generation. See the verified Node and Bun transport.
