• Experts.js is a JavaScript framework that simplifies using OpenAI's Assistants API to build multi-agent AI systems. It removes the complexity of managing Run objects and enables linking assistants as tools.
  

• Assistants are AI agents with instructions and tools.

  They can use normal OpenAI tools, function calling, and other assistants as tools.
  

• Tools are subclasses of assistants, acting as reusable components in the system.

  They can be LLM-backed, performing actions based on their parent assistant's requests, or non-LLM tools, implementing custom logic.
  

• Threads are managed context windows for agents, essentially acting as their memory.
  Experts.js handles thread creation and management, ensuring each tool has its own thread to avoid locking issues.
  

• Experts.js provides an easy-to-use "ask" interface to interact with assistants.

  You don't need to manage Run objects directly. It also offers streaming capabilities, allowing applications to receive real-time outputs from the assistants.
  

• The framework includes advanced features like lifecycle hooks and token usage metrics.

  You can customize assistant initialization and track token consumption.

Experts.js enables the creation of multi-tier agent systems where different assistants specialize in specific domains and collaborate to solve complex problems.

For example, a company assistant can have a merchandising expert tool, which, in turn, uses an OpenSearch tool for searching a product catalog.
