The way to build agents with Vercel AI SDK is to combine the use of streamText and generateText.
with tools that can be passed to these functions.
The vercel ai sdk does not provide tools itself, but in the documentation it lists options of compatible tools.
import { generateText } from "ai";
import { openai } from "@ai-sdk/openai";
const result = await generateText({
model: openai("gpt-4o"),
prompt: "What is the capital of France?",
tools: [
{
type: "function",
function: {
name: "get_capital",
description: "Get the capital of a country",
parameters: z.object({
country: z.string(),
}),
},
},
],
});
console.log(result.text);
