The Vercel AI SDK provider does not expose a built-in listModels() helper. Use one of these patterns to keep model IDs current.

​
Option 1: Fetch from the Gateway API

const response = await fetch("https://api.phaseo.app/v1/gateway/models", {
  headers: {
    Authorization: `Bearer ${process.env.AI_STATS_API_KEY}`,
  },
});

if (!response.ok) {
  throw new Error(`Failed to load models: ${response.status}`);
}

const models = await response.json();
console.log(models);

​
Option 2: Use the official TypeScript SDK

import { AIStats } from "@ai-stats/sdk";

const client = new AIStats({ apiKey: process.env.AI_STATS_API_KEY! });
const models = await client.getModels();

console.log(models);

​
Using discovered IDs with AI SDK

import { aiStats } from "@ai-stats/ai-sdk-provider";
import { generateText } from "ai";

const result = await generateText({
  model: aiStats("openai/gpt-5-nano"),
  prompt: "Hello from a discovered model ID.",
});

console.log(result.text);

​
Notes

  • Model IDs use provider/model format.
  • Re-check model availability periodically for routing and deprecations.
  • Prefer selecting IDs from /v1/gateway/models over hard-coding long-term.
