NodeLLM is an open-source backend AI SDK designed specifically for Node.js, providing a provider-agnostic infrastructure layer to build production-grade Large Language Model (LLM) systems. With NodeLLM, developers can seamlessly integrate over 540 models from various providers including OpenAI, Anthropic, Gemini, DeepSeek, and more, using a consistent API that remains stable even as provider services evolve.

Key Features:

• Unified API: Simplifies the process of connecting to multiple LLM providers, thereby eliminating the need to handle distinct SDKs or differing API methods.

• Backend Optimization: Prioritizes system reliability and supports backend orchestration suitable for a variety of applications such as workers, cron jobs, and API servers.

• Contract-Driven Architecture: Ensures consistent behavior across streaming and tools, enabling a predictable implementation across diverse models.

• Flexible Configuration: The configuration system is designed for enterprise use, allowing users to connect to multiple providers through environment variables, minimizing common setup issues typical in backend services.

• Multi-Provider & Features: Supports a wide array of advanced functionalities including:

  • Integrated audio transcription and automatic image handling.
  • Native handling of reasoning models, enabling deep logical analysis using available models like OpenAI o1/o3.
  • Middleware support for request auditing, cost tracking, and personal data management.
  • Automated persistence for interaction history and API metrics, which assists in maintaining comprehensive records of usage.

Example Usage:

NodeLLM enables users to engage in chat and streaming seamlessly. Here’s a quick coding example:

import { NodeLLM } from "@node-llm/core";

const chat = NodeLLM.chat("gpt-4o");
const response = await chat.ask("Explain event-driven architecture");
console.log(response.content);

for await (const chunk of chat.stream("Explain event-driven architecture")) {
  process.stdout.write(chunk.content);
}

Notable Capabilities:

• Smart Vision & Files: Effortlessly analyze various file types including images and PDFs through native API calls.
• Tool Management: Define tools once and let NodeLLM handle their execution in both chat and streaming scenarios.
• Deep Reasoning Access: Obtain insights into the thought processes of intelligent systems through specific model commands.
• Robust Debugging: Comprehensive logging of all API requests and responses across platforms enhances monitoring and troubleshooting.
