Vercel AI SDK

The AI SDK is the fastest way to build your own agent on Depaza models. Use the @ai-sdk/openai-compatible provider.

Depaza API key

Model

Your key stays in this browser (local storage) and is sent only to depaza.eu. Every config block on this page fills in automatically. Don’t do this on a shared machine.

Keep DEPAZA_API_KEY server-side. Never ship it to a browser bundle. This is not Vercel’s AI Gateway — the provider talks to Depaza directly.

Install

shell

npm i ai @ai-sdk/openai-compatible zod

Create the provider

depaza.ts

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

export const depaza = createOpenAICompatible({
  name: 'depaza',
  baseURL: '{{BASE_URL}}',
  apiKey: process.env.DEPAZA_API_KEY,
});

Generate and stream

example.ts

import { generateText, streamText } from 'ai';
import { depaza } from './depaza';

const model = depaza('{{MODEL}}');

const { text } = await generateText({
  model,
  prompt: 'Explain what a GPU kernel is in two sentences.',
});

Tool calling

agent.ts

import { generateText, tool, stepCountIs } from 'ai';
import { z } from 'zod';
import { depaza } from './depaza';

const result = await generateText({
  model: depaza('{{MODEL}}'),
  prompt: 'What is the weather in Paris?',
  stopWhen: stepCountIs(5),
  tools: {
    get_weather: tool({
      description: 'Get the weather for a city',
      inputSchema: z.object({ city: z.string() }),
      execute: async ({ city }) => ({ city, temp: '18C' }),
    }),
  },
});
