Features

• Fast Inference: Access to Fireworks’ optimized inference infrastructure
• OpenAI Compatible: Inherits all features from the OpenAI provider
• Streaming: Full streaming support inherited from OpenAI provider
• Open-Source Models: Access to Llama, Mixtral, and other open models
• Fine-Tuned Models: Support for custom fine-tuned model deployments

Installation

npm install @memberjunction/ai-fireworks

Usage

import { FireworksLLM } from '@memberjunction/ai-fireworks';

const llm = new FireworksLLM('your-fireworks-api-key');

const result = await llm.ChatCompletion({
    model: 'accounts/fireworks/models/llama-v3p1-70b-instruct',
    messages: [
        { role: 'user', content: 'What are the benefits of open-source AI models?' }
    ],
    temperature: 0.7
});

if (result.success) {
    console.log(result.data.choices[0].message.content);
}

How It Works

FireworksLLM is a thin subclass of OpenAILLM that redirects API calls to Fireworks’ endpoint at https://api.fireworks.ai/inference/v1. All chat, streaming, and parameter handling logic is inherited from the OpenAI provider.

Class Registration

Registered as FireworksLLM via @RegisterClass(BaseLLM, 'FireworksLLM').
