They waste money because they retrieve too much information before asking the model to think.\n\nEveryone talks about choosing cheaper models, writing better prompts, or reducing context size to cut LLM costs.\n\nBut after working on enterprise AI agents, I noticed something else.**non members can read here**\n\nThe biggest source of unnecessary cost wasn’t the LLM.\n\nIt was **how the agent decided what to retrieve before calling the LLM.**\n\nA smarter retrieval strategy can often save more tokens than switching to a smaller model.\n\n## A Real Example\n\nImagine you’re building an AI engineering assistant connected to:\n\n- GitHub\n- Jira\n- Confluence\n- Logs\n- Knowledge Graph\n- Internal documentation\n\nA developer asks:\n\n“Why is the checkout service failing after yesterday’s deployment?”\n\nA typical agent might do this:\n\n```\nSearch GitHub↓Search Jira↓Search…\n```\n\n", "url": "https://wpnews.pro/news/how-intelligent-query-planning-can-reduce-llm-costs-in-production-ai-agents", "canonical_source": "https://blog.stackademic.com/how-intelligent-query-planning-can-reduce-llm-costs-in-production-ai-agents-61cc29259094?source=rss----d1baaa8417a4---4", "published_at": "2026-07-30 09:54:14+00:00", "updated_at": "2026-07-30 09:56:49.251203+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-agents", "large-language-models", "ai-infrastructure"], "entities": ["GitHub", "Jira", "Confluence"], "alternates": {"html": "https://wpnews.pro/news/how-intelligent-query-planning-can-reduce-llm-costs-in-production-ai-agents", "markdown": "https://wpnews.pro/news/how-intelligent-query-planning-can-reduce-llm-costs-in-production-ai-agents.md", "text": "https://wpnews.pro/news/how-intelligent-query-planning-can-reduce-llm-costs-in-production-ai-agents.txt", "jsonld": "https://wpnews.pro/news/how-intelligent-query-planning-can-reduce-llm-costs-in-production-ai-agents.jsonld"}}
