Quick guide how to use the Vercel AI SDK with TSX to create executable Node.js scripts that use AI.

1. Install tsx globally

   npm install -g tsx

2. Install node modules

   npm i ai @ai-sdk/openai dotenv @types/node

3. Add OpenAI API key to .env (OPENAI_API_KEY)
4. Write a .mts script (e.g. hello-world.mts)

   #!/usr/bin/env tsx
   
   import { openai } from "@ai-sdk/openai";
   import { streamText } from "ai";
   import { configDotenv } from "dotenv";
   
   configDotenv();
   
   const { textStream } = await streamText({
     model: openai("gpt-4o"),
     prompt: "How can I list files in bash?",
   });
   
   for await (const textPart of textStream) {
     process.stdout.write(textPart);
   }

5. Make executable: chmod +x hello-world.mts
6. Run: ./hello-world.mts
