NotDiamond Node API Library

This library provides convenient access to the NotDiamond model routing API from TypeScript or JavaScript. NotDiamond helps you select the best AI model for your specific use case, optimizing for factors like cost, latency, or performance.

Installation

npm install notdiamond

For Deno users:

import { NotDiamond } from 'https://deno.land/x/notdiamond@v1.0.0/mod.ts';

Quick Start

To use the API, you need to sign up for a NotDiamond account and obtain an API key. Sign up here.

Basic Usage

Here's a simple example of how to use NotDiamond to select the best model between GPT-4o, Claude 3.5 Sonnet, and Gemini 1.5 Pro, while optimizing for latency:

import { NotDiamond } from 'notdiamond';

const notDiamond = new NotDiamond({
  // Optional - automatically loads from environment variable
  apiKey: process.env.NOTDIAMOND_API_KEY,
});

async function basicExample() {
  // 1. Select the best model
  const result = await notDiamond.modelSelect({
    // Define the user's message
    messages: [{ content: 'What is 12x12?', role: 'user' }],
    // Specify the LLM providers and models to choose from
    llmProviders: [
      { provider: 'openai', model: 'gpt-4o-2024-05-13' },
      { provider: 'anthropic', model: 'claude-3-5-sonnet-20240620' },
      { provider: 'google', model: 'gemini-1.5-pro-latest' },
    ],
    // Set the optimization criteria to latency
    tradeoff: 'latency',
  });

  // 2. Handle potential errors
  if ('detail' in result) {
    console.error('Error:', result.detail);
    return;
  }

  // 3. Log the results
  // Display the selected provider(s)
  console.log('Selected providers:', result.providers);
  // Show the unique session ID for this request
  console.log('Session ID:', result.session_id);
}

basicExample();

Advanced Usage with Tools

You can also use NotDiamond with custom tools:

import { NotDiamond, Tool } from 'notdiamond';

const notDiamond = new NotDiamond();

// Define custom tools for the AI to use
const tools: Tool[] = [
  {
    type: 'function',
    function: {
      name: 'multiply',
      description: 'Multiplies two numbers.',
      parameters: {
        type: 'object',
        properties: {
          a: { type: 'integer' },
          b: { type: 'integer' },
        },
        required: ['a', 'b'],
      },
    },
  },
];

async function toolCallingExample() {
  const result = await notDiamond.modelSelect({
    messages: [{ content: 'What is 12x12?', role: 'user' }],
    llmProviders: [
      { provider: 'openai', model: 'gpt-4-1106-preview' },
      { provider: 'anthropic', model: 'claude-3-sonnet-20240229' },
    ],
    // Include custom tools in the request
    tools: tools,
    // Optimize for cost instead of latency
    tradeoff: 'cost',
    // Allow selection of up to 2 models
    maxModelDepth: 2,
  });

  if ('detail' in result) {
    console.error('Error:', result.detail);
    return;
  }

  console.log('Selected providers:', result.providers);
  console.log('Session ID:', result.session_id);
}

toolCallingExample();

API Reference

For a complete API reference and more detailed documentation, please check our API Documentation.

Key Concepts

• llmProviders: An array of AI providers and models you want NotDiamond to choose from.
• tradeoff: The factor to optimize for (e.g., 'latency', 'cost', 'performance').
• tools: Custom functions that the AI can use to perform specific tasks.
• maxModelDepth: The maximum number of models to include in the response (for advanced use cases).

Error Handling

NotDiamond uses typed responses. If there's an error, the response will have a detail property with the error message. Always check for this property when handling responses.
