AI Agents

An AI agent is a system that uses a language model to plan and take actions — calling tools, querying systems, completing multi-step tasks — rather than only answering a question. Enterprise agents need tool integration, guardrails, evaluation, and human-in-the-loop controls to be trusted in production.

Need hands-on help? Lazlo is an AI development company that builds these systems in production — explore our AI development services.

Agents turn an LLM from a text generator into a system that gets work done: it reasons about a goal, calls tools, observes results, and continues. The hard part is not the model — it's the tooling, guardrails, and evaluation around it.

What a production agent needs

  • Tools — typed, permissioned access to your APIs and data (the Model Context Protocol standardises this).
  • Guardrails — input/output validation, allow-lists, and spend/rate limits.
  • Evaluation — automated checks on real tasks before and after each change.
  • Human-in-the-loop — approval gates for high-consequence actions.

Where agents earn their keep

Support triage, operations automation, data processing, and internal copilots — anywhere a defined multi-step process can be delegated with oversight.

Frequently asked questions

An AI agent uses a language model to plan and take actions — calling tools, querying systems and completing multi-step tasks — rather than only answering a question. Production agents add tool integration, guardrails, evaluation and human oversight.

Use an agent when a defined, multi-step process can be delegated with oversight (support triage, ops automation, data processing). For single-shot answers, a simpler grounded (RAG) feature is cheaper and safer.
