A Blueprint Architecture of Compound AI Systems for Enterprise
Abstract: LLMs have showcased remarkable capabilities surpassing conventional NLP challenges, creating opportunities for use in production use cases. Towards this goal, there is a notable shift to building compound AI systems, wherein LLMs are integrated into an expansive software infrastructure with many components like models, retrievers, databases and tools. In this paper, we introduce a blueprint architecture for compound AI systems to operate in enterprise settings cost-effectively and feasibly. Our proposed architecture aims for seamless integration with existing compute and data infrastructure, with ``stream'' serving as the key orchestration concept to coordinate data and instructions among agents and other components. Task and data planners, respectively, break down, map, and optimize tasks and data to available agents and data sources defined in respective registries, given production constraints such as accuracy and latency.

What this paper is about (the big picture)
This paper suggests a “blueprint” (a detailed plan) for building AI systems inside companies that combine LLMs with many other tools and databases. Instead of relying on one big model to do everything, the authors propose a team-based setup where different “agents” (specialized programs) work together, share information smoothly, and meet real-world needs like being fast, accurate, and affordable.
What questions the authors are trying to answer
The paper focuses on three main goals:
- How can companies plug AI into the systems and data they already have without rebuilding everything?
- How can we coordinate many AI components so they work together efficiently, not chaotically?
- How can we keep costs down and quality high while meeting practical limits like time (latency) and accuracy?
How the approach works (in everyday terms)
Think of this system like a well-run group project:
- Agents are team members with different skills. One might search a database, another might summarize text, and another might call an LLM for creative writing. Each agent can have multiple “workers,” so several tasks can happen at once.
- An Agent Registry is like the company directory for AI tools. It describes what each agent can do and what it needs.
- A Data Registry is like a catalog for all the company’s data—where it lives, what it looks like, and how to use it—so agents can find the right information.
- Streams are the group chats or conveyor belts that carry messages and data between agents. They keep everything moving and organized. For example, a user typing a request creates a stream of messages that agents can read and respond to.
- Sessions are like meeting rooms. They set the context for one job or conversation so agents know they’re working on the same thing.
- A Task Planner is the project planner. It breaks big jobs into smaller steps and arranges them in a to-do map called a DAG (directed acyclic graph). You can think of a DAG as a checklist with arrows showing which tasks must happen before others.
- A Task Coordinator is the project manager or traffic controller. It assigns tasks to the right agents, watches the progress, keeps things on schedule, and asks the planner to adjust the plan if something goes wrong (like a slow agent or low-quality result).
- A Data Planner is the data strategist. It figures out the smartest way to get and prepare the data (e.g., find, query, summarize, join) so the agents have what they need quickly and cheaply.
Together, these pieces create an event-driven system: when something happens (a new message in a stream), the right agents react automatically.
What the paper’s main ideas and “results” are
This is a design paper, not a report of experiments. Its main contributions are:
- A clear, reusable architecture for “compound AI systems” where many specialized agents (including LLMs) work together.
- A simple, universal way to coordinate work (streams and sessions) so data and instructions flow smoothly.
- Planners (task and data) that optimize what gets done, by whom, and when, to meet real-world constraints like speed, cost, and accuracy.
- Practical “touchpoints” (agent and data registries) that make it easy to integrate with the company’s existing models, APIs, and databases.
Why this matters:
- It helps companies build AI that’s reliable, flexible, and easier to control.
- It encourages using the right tool for the job instead of forcing one model to do everything.
- It supports cost savings and better performance by planning and monitoring how tasks run.
Why this could be a big deal
If companies follow this blueprint:
- They can turn AI ideas into real, trustworthy products faster (e.g., better job matching, smarter search, more helpful chat assistants).
- They can reuse what they already have—models, data, and services—rather than starting from scratch.
- They keep humans in control of quality and cost, because the system is designed to be monitored, adjusted, and improved.
In short, the paper argues that building AI like a coordinated team—rather than relying on a single “super model”—is a smarter, more practical way to use AI in the real world.
