How to Use ModelFusion: A Step-by-Step Guide

Let’s dive into some practical examples using ModelFusion. To better understand the usage, imagine using ModelFusion as a Swiss army knife for AI capabilities; it gives you various tools to tackle different tasks in AI application development.

Example: Generating Text

First, you can generate text using AI. Imagine you want to tell a story about a robot learning to love. Here’s how you do it:

import { generateText, openai } from 'modelfusion';

const text = await generateText({
  model: openai.CompletionTextGenerator({ model: 'gpt-3.5-turbo-instruct' }),
  prompt: 'Write a short story about a robot learning to love:'
});

In this script, you specify the model and what you want it to write as a prompt, and voilà! Your AI-generated story is ready.

Example: Streaming Text

Want to stream text, similar to listening to a podcast getting recorded live? Here’s how:

import { streamText, openai } from 'modelfusion';

const textStream = await streamText({
  model: openai.CompletionTextGenerator({ model: 'gpt-3.5-turbo-instruct' }),
  prompt: 'Write a short story about a robot learning to love:'
});

for await (const textPart of textStream) {
  process.stdout.write(textPart);
}

This allows you to receive pieces of text sequentially, allowing for a dynamic writing experience.

Troubleshooting

If you encounter any issues during installation or while using ModelFusion, here are some troubleshooting tips:

Ensure your Node.js version is compatible with ModelFusion.
Double-check API keys for any integrations needed.
