For its user assistant, Brex moved beyond a single agent with many tools. Instead, they built a network where specialized sub-agents (e.g., policy, travel) have multi-turn conversations with an orchestrator agent to collaboratively solve complex user requests.

After successfully deploying three or four AI agents, companies will encounter a new challenge: the agents have data conflicts and provide inconsistent answers. The solution, which is still nascent, is a "meta-agent" or orchestration layer to manage them.

True Agentic AI isn't a single, all-powerful bot. It's an orchestrated system of multiple, specialized agents, each performing a single task (e.g., qualifying, booking, analyzing). This 'division of labor,' mirroring software engineering principles, creates a more robust, scalable, and manageable automation pipeline.

Major AI platforms are becoming "super agents" that connect to a user's software (e.g., email, YouTube) and use "skills" to perform complex, autonomous tasks. This convergence means the choice of platform is becoming a matter of user interface and integration preference rather than unique functionality.

Don't fear deploying a specialized, multi-agent customer experience. Even if a customer interacts with several different AI agents, it's superior to being bounced between human agents who lose context. Each AI agent can retain the full conversation history, providing a more coherent and efficient experience.

As businesses deploy multiple AI agents across various platforms, a new operations role will become necessary. This "Agent Manager" will be responsible for ensuring the AI workforce functions correctly—preventing hallucinations, validating data sources, and maintaining agent performance and integration.

Contrary to the trend toward multi-agent systems, Tasklet finds that one powerful agent with access to all context and tools is superior for a single user's goals. Splitting tasks among specialized agents is less effective than giving one generalist agent all information, as foundation models are already experts at everything.

Instead of siloing agents, create a central memory file that all specialized agents can read from and write to. This ensures a coding agent is aware of marketing initiatives or a sales agent understands product updates, creating a cohesive, multi-agent system.

The most powerful AI systems consist of specialized agents with distinct roles (e.g., individual coaching, corporate strategy, knowledge base) that interact. This modular approach, exemplified by the Holmes, Mycroft, and 221B agents, creates a more robust and scalable solution than a single, all-knowing agent.
