🕵️‍♀️ Agents
AI agents are LLM applications that are designed to perform tasks independently or alongside other AIs and humans. They range from simple functions like web searches to complex ones like building web applications and conducting research. Here you find tools and frameworks to build and orchestrate AI agents.

About Agents
AI agent platforms enable building autonomous LLM applications that can reason, plan, and take actions using external tools. Unlike simple chat interfaces, agents can break down complex tasks, use APIs, browse the web, write and execute code, and iterate on their results until a goal is achieved.
The agent ecosystem is evolving rapidly. Platforms range from low-code agent builders to developer-focused SDKs that give fine-grained control over planning, tool selection, and safety guardrails. Multi-agent architectures, where specialized agents collaborate on different aspects of a task, are becoming a common pattern for complex workflows.
Key considerations when choosing an agent platform include supported tool integrations, planning and reasoning capabilities, safety controls, observability into agent decision-making, and the ability to define custom workflows and fallback behaviors.
Frequently Asked Questions
What is an AI agent?
An AI agent is an LLM application that can autonomously plan and execute multi-step tasks. Unlike a chatbot that responds to single prompts, an agent can use tools (APIs, code execution, web browsing), maintain state across steps, and iterate until it achieves a defined goal.
When should I build an agent instead of a simple LLM chain?
Use agents when the task requires dynamic decision-making: when the number of steps is not known in advance, when tool selection depends on intermediate results, or when the system needs to handle errors and retry with different approaches. For predictable, fixed-step workflows, a simple chain is more reliable and easier to debug.
How do I make agents reliable in production?
Set clear boundaries on what tools the agent can access, implement timeout and retry limits, add human-in-the-loop checkpoints for high-stakes actions, log every decision for debugging, and use evaluation frameworks to test agent behavior across diverse scenarios. Start with narrow, well-defined tasks before expanding scope.
