Orchestrators: The brain behind efficient agentic systems

By Antonio CernadasMarch 10, 20263 min read

In the world of Artificial Intelligence, the idea is often sold that a language model (LLM) can "do everything". But those of us in the day-to-day of operations know that real scalability depends on architecture, not just the model.

At AyGLOO, our experience tells us that an agent system without orchestration is like a company without middle management: pure operational chaos.

The context window wall

The main reason we need orchestrators is physical: the context window is finite.

For an Agent to be useful, it must be filled with instructions and information. If we try to have a single Agent simultaneously contain the company culture, customer needs, software features, code and technical documentation... it simply cannot. The "noise" saturates its processing capacity and performance plummets.

Orchestration: Understand, Define and Delegate

The systems that perform best are, without doubt, those with Orchestrators. Their function is identical to that of a good manager in a company:

  • Deeply understand the organisation and the real needs of the customer.
  • Make a precise definition of what must be executed.
  • Invoke specialist agents only when necessary, giving them the exact amount of context and critical instructions for that task.

In this way, specialist agents have their context window free to focus 100% on executing, searching for additional information and solving the problem without distractions.

Ephemeral execution and Intelligent Memory

Once the task is completed successfully, the invoked agent vanishes. We do not need it to occupy resources forever.

However, here a key piece of our architecture comes in: memory management. To decide what is important to remember and what must be forgotten, we use a type of agent specialised in data curation. This agent analyses the intervention and decides which information is a relevant asset for the future of the company and the customer, storing it in the database and discarding the rest.

Conclusion: Architecture vs. Brute Force

We have a maxim at AyGLOO: A well-structured AI delivers better results and is much cheaper than the most powerful AI on the market working without control. It is not about having the largest model, but about having the most intelligent architecture. Orchestration is not a technical luxury, it is the foundation of an AI system that really works in the real world.
