Zodchat is a GPT-4 interface that allows you to get well-typed and structured data It is like TypeChat but with Zod and function calls

Example

see more in examples/

const Song = zod
  .object({
    name: zod.string().describe('Name of the song to play'),
    artist: zod.string().describe('Name of the artist of the song'),
    genre: zod
      .string()
      .array()
      .describe('Genre of the song using whimsical words'),
    vibe: zod
      .string()
      .describe('General vibe of the song using whimsical words'),
  })
  .describe('A song to play')

  await prompt({
    output_schema: Playlist,
    system_prompt: 'Please give a chill instrumental song',
  })

How to use

With bun:

bun add zodchat

Or yarn:

yarn add zodchat

Generate an API key, then put it in your local .env.local file:

OPENAI_API_KEY=your_key_here

or use ```sh export OPENAI_API_KEY=your_key_here

Then you can directly import and use the library:

```ts
import { prompt } from 'zodchat'

Tip for prompting

• Telling GPT-4 to use whimsical words usually leads it to produce more diverse object-level outputs. In examples/song for instance, asking for "whimsical words" genres makes it output different genres than just the one asked for.
• GPT will use the output schema to prompt itself, therefore it is often useful to ask it for more information than is needed. For instance, in examples/songs, asking for just {name, artist} would make it match on title (Eruption of Ignorance would lead it to suggest many fire-related titles). Including genre and vibes in the requested output lead it to actually match on them.
• Be careful about token consumption, as the whole schema is passed, it can be very resource expensive
