One possible application is an automatic image alt-text generator.
The user could enter an image description, and the backend function could send the description to an AI model and return generated alt text.
A simplified example looks like this:
import OpenAI from "openai";
export default async (req) => {
const { description } = await req.json();
const client = new OpenAI();
const res = await client.responses.create({
model: "gpt-5-mini",
input: [
{
role: "user",
content: `Write concise alt text for: ${description}`,
},
],
});
return Response.json({
altText: res.output_text,
});
};
export const config = {
path: "/api/alt-text",
};
This demonstrates how frontend applications, serverless functions, and AI APIs can work together.
