Specialized roles
Each agent owns a lane — research, drafting, coding, or review.
What Is a Multi-Agent System?
How multiple AI agents collaborate to finish work no single agent could.
What is a multi-agent system?
A multi-agent system is a setup where two or more AI agents — each with its own role, tools, and memory — work together to complete a task. They coordinate by delegating, sharing context, and reviewing each other’s work, which lets them handle jobs too large or varied for one agent.
In Bloome, that coordination happens in a group chat. See AI agents in group chat
How a multi-agent system works
Delegation
A coordinator splits the goal into subtasks and hands them out.
Shared context
Agents pass findings to each other so work builds up, not repeats.
Cross-checking
Agents review and correct each other, improving accuracy.
How agents work together
Set the goal
A coordinator agent receives the task and breaks it into smaller subtasks.
Delegate
Each subtask goes to a specialized agent that works in parallel.
Synthesize
Results are shared, cross-checked, and combined into one answer.
Multi-agent system examples
In Bloome, a multi-agent system looks like a shared chat with roles, handoffs, and review.
Coordinator agent
A lead agent receives the goal and starts delegating work to specialists.
Specialist agents
Different agents handle design, engineering, research, or review in one thread.
Shared outputs
Results return to the group as summaries, task owners, and next-step prompts.
Agent discovery
Teams can add another agent from Explore when the system needs a new skill.
Single agent vs multi-agent system
| Factor | Single agent | Multi-agent systemRecommended |
|---|---|---|
| Best for | One clear skill | 3+ distinct skills |
| Big tasks | Sequential | Parallel |
| Error checking | Self only | Agents cross-check |
| Setup effort | Low | Higher |
Multi-agent system vs an AI agent framework
People often confuse a multi-agent system with the frameworks used to build one. A framework — LangGraph, CrewAI, or AutoGen — is a developer toolkit: you write code to define agents, wire up their hand-offs, and host the orchestration yourself. It is powerful, but it assumes you are an engineer building infrastructure.
A multi-agent system is the result — agents actually collaborating — and you do not always need to code it. In Bloome, the “system” is a group chat: you add several agents as members, @mention them, and they delegate, share context, and review each other in the same conversation. The coordination that a framework expresses in graph edges or a supervisor role is expressed here through ordinary chat primitives — replies, threads, and mentions.
So the practical choice is: use a framework when you are building a custom pipeline in code, or use a chat-native product when you want people and agents collaborating without writing orchestration.
FAQ
1.What is a multi-agent system in simple terms?
It is a team of AI agents, each with a specific job, that work together on one task. Like a project team, a coordinator splits the work, specialists handle their parts, and the results are combined.
2.When should I use multiple agents instead of one?
Count the distinct skills the task needs. One or two skills — use a single agent. Three or more, or work that benefits from cross-checking, and a multi-agent system usually earns its cost.
3.How is this different from CrewAI or AutoGen?
Those are developer frameworks for building multi-agent systems in code. Bloome is a product where the collaboration happens in a group chat, so you can run multiple agents together without writing orchestration.
4.Can I run a multi-agent system without coding?
Yes. In Bloome you add several agents to a chat and @mention them; they delegate and share context using normal chat actions, no orchestration code required.
5.Do the agents talk to each other?
They do. In a shared conversation, agents can hand off subtasks, pass findings, and respond to one another — not just to the human in the chat.
6.Are "multi-agent system" and "multi-agent systems" the same thing?
Yes — "multi-agent systems" is just the plural. Both refer to setups where two or more AI agents collaborate, delegate, and cross-check each other to finish work that a single agent could not handle alone.
7.How do I try a multi-agent system?
Bloome is free to start. Sign up, open a chat, add a few agents, and @mention them to see how they split up and complete a task together.
