Catai API

Catai provides multiple APIs to interact with the model.

Local API

The local API is only available in Node.js.

Enable you to chat with the model locally on your computer.

import {createChat} from 'catai';

const chat = await createChat(); // using the default model installed

const response = await catai.prompt('Write me 100 words story', token => {
    progress.stdout.write(token);
});

console.log(`Total text length: ${response.length}`);

You can also specify the model you want to use:

import {createChat} from 'catai';
const chat = await createChat({model: "llama3"});

If you want to install the model on the fly, please read the install-api guide

Remote API

Allowing you to run the model on a remote server.

Simple API

Node.js & Browser compatible API:

const response = await fetch('http://127.0.0.1:3000/api/chat/prompt', {
    method: 'POST',
    body: JSON.stringify({
        prompt: 'Write me 100 words story'
    }),
    headers: {
        'Content-Type': 'application/json'
    }
});

const data = await response.text();

const response = await fetch('http://127.0.0.1:3000/api/chat/prompt', {
    method: 'POST',
    body: JSON.stringify({
        prompt: 'Write me 100 words story'
    }),
    headers: {
        'Content-Type': 'application/json'
    }
});

const reader = response.body.pipeThrough(new TextDecoderStream())
    .getReader();

while (true) {
    const {value, done} = await reader.read();
    if (done) break;
    console.log('Received', value);
}

    process.stdout.write(token);
});

console.log(`Total text length: ${response.length}`);
