When Serverless
Can't Keep Up with AI

// 1. Define AI route
import { route } from '@spfn/core/route';
import { Type } from '@sinclair/typebox';
import OpenAI from 'openai';

const openai = new OpenAI();

export const chat = route
  .post('/chat')
  .input({
    body: Type.Object({
      message: Type.String()
    })
  })
  .handler(async (c) => {
    const { body } = await c.data();
    // No timeout - takes as long as needed
    return await openai.chat.completions.create({
      model: 'gpt-4',
      messages: [{ role: 'user', content: body.message }]
    });
  });

// 2. Add to router
import { defineRouter } from '@spfn/core/route';
import { chat } from './routes/chat';

export const appRouter = defineRouter({
  chat,
});

export type AppRouter = typeof appRouter;

// 3. Call from Next.js
import { api } from '@/lib/api-client';

// Fully typed, no timeout issues
const response = await api.chat.call({
  body: { message: 'Explain quantum computing' }
});

// Or stream the response
const stream = await api.chat.stream({
  body: { message: 'Write a story' }
});
