OpenAI Agents JS enables developers to construct AI agents by combining OpenAI models with custom toolsets. Agents can process user input, call external APIs, manage stateful conversations with memory modules, and perform tasks like web scraping, code generation, or data lookup. The framework offers a plugin system for registering tools, a standardized Agent class for orchestration, built-in memory abstractions, and support for both chat-based and completion-based models. Features include error recovery, multi-tool orchestration, and customizable middleware. By defining tools and feeding them into the agent instance, you can deploy sophisticated AI-driven workflows in Node.js or browser contexts with minimal boilerplate. Additionally, it simplifies API key management and supports asynchronous operations, allowing agents to execute long-running tasks or integrate with databases and messaging queues effortlessly.

Astro Agents provides a modular architecture for building AI agents in JavaScript and TypeScript. Developers can register custom tools for data lookup, integrate memory stores to preserve conversational context, and orchestrate multi-step reasoning workflows. It supports multiple LLM providers such as OpenAI and Hugging Face, and can be deployed as static sites or serverless functions. With built-in observability and extensible plugins, teams can prototype, test, and scale AI-driven assistants without heavy infrastructure overhead.
