What are AI Agents?

AI Agents are systems powered by Large Language Models that use the ReAct (Reasoning + Acting) pattern to break down complex problems, call external tools, and execute multi-step workflows through iterative reasoning loops.

ReAct Loop

The core reasoning pattern that lets agents think through problems step-by-step, decide what action to take, observe results, and iterate until the task is complete.

Reason about the current state

Act by calling tools or APIs

Observe the results

Repeat until complete

Tool Integration

Connect agents to your external APIs and services. Agents use ReAct reasoning to select which tools to call and parse the responses to complete tasks.

Web search & data retrieval

Database queries

API integrations

Custom functions

How to Build an Agent

Four simple steps to create your AI agent

System Prompt

Define your agent's role, personality, and behavior guidelines

Select Tools

Add your APIs as tools that the agent can call during reasoning loops

Configure

Choose base model, LoRA adapter, and output schema

Create & Run

Start using your agent via a simple REST API
