The founder said Acyclic Labs is building infrastructure to scale agents and wants to map the use cases and pain points — state sync, token costs, cascading failures, and latency — that drive large agent swarms in production. The thread had 1 point and 0 comments at the time of the post.", "body_md": "I feel like most AI workflows can be solved pretty effectively by a single capable LLM or with upto 5 subagents however, many engineering teams are focused on multi-agent architectures at huge scales.\n\nCurious to understand exactly when it becomes worth it / what production use cases there are for large multi-agent swarms: I’m trying to understand exactly where that value lies.\n\nIf you are run agent swarms in production: what is the main use case / need and what is your biggest pain point right now (state sync, token costs, cascading failures, latency)?\n\n[As context: I am a founder at Acyclic Labs (YC F26) and we are building infra to scale agents. Looking to map out when the swarms are actually justified and when they are wasteful!]\n\nComments URL: [https://news.ycombinator.com/item?id=49689454](https://news.ycombinator.com/item?id=49689454)\n\nPoints: 1\n\n# Comments: 0", "url": "https://wpnews.pro/news/ask-hn-multi-agent-workflows-in-production-where-people-using-1000s-of-agents", "canonical_source": "https://news.ycombinator.com/item?id=49689454", "published_at": "2026-09-13 22:37:42+00:00", "updated_at": "2026-09-13 22:52:09.364344+00:00", "lang": "en", "topics": ["ai-agents", "ai-infrastructure", "ai-startups", "ai-products"], "entities": ["Acyclic Labs", "Y Combinator", "Hacker News"], "alternates": {"html": "https://wpnews.pro/news/ask-hn-multi-agent-workflows-in-production-where-people-using-1000s-of-agents", "markdown": "https://wpnews.pro/news/ask-hn-multi-agent-workflows-in-production-where-people-using-1000s-of-agents.md", "text": "https://wpnews.pro/news/ask-hn-multi-agent-workflows-in-production-where-people-using-1000s-of-agents.txt", "jsonld": "https://wpnews.pro/news/ask-hn-multi-agent-workflows-in-production-where-people-using-1000s-of-agents.jsonld"}}
