Community discusses multi-agent loop patterns for AI workflows

This r/AI_Agents post covers multi-agent loops — a design where several AI agents pass results back and forth in cycles to tackle complex tasks. Each agent handles a piece of the work, checks the previous agent's output, and feeds improvements forward. It's directly relevant to anyone building AI agent systems and trying to manage costs.

A multi-agent loop works like a relay: agent A drafts something, agent B reviews and improves it, agent A refines again — and so on until the task is done well enough. This cyclic collaboration lets agents catch each other's mistakes and produce higher-quality results than a single agent working alone.

The main trade-off is cost: every loop iteration means more LLM calls and more tokens consumed. Designing a clear stopping condition — how many rounds to run, or when the output is 'good enough' — is the key to keeping token costs under control. The r/AI_Agents community shares hands-on implementation experiences and pitfalls around these patterns.

Key points

  • Multiple agents take turns refining each other's output in a repeating cycle
  • This approach handles complex tasks better than a single agent working alone
  • More loop iterations mean more LLM calls and higher token costs
  • A clear stopping condition is essential to avoid runaway costs
  • The community shares real implementation tips and lessons learned

Quick term guide

multi-agent
A setup where several AI agents each handle a different subtask and work together to complete a larger goal.
AI agents
AI agents are AI tools that can carry out steps toward a goal, not just answer once.
AI agent
An AI program that can inspect information and suggest what to do next.
LLM call
Sending a question or instruction to an AI language model (like ChatGPT or Claude) and receiving its response.
token costs
Token costs are the fees paid for the text an AI model reads and writes.
token cost
The money or usage spent when sending text to an AI model and getting text back.
