The optimization was tested with Gemma 4 E4B as the LLM.", "body_md": "I have been experimenting with **optimizing** my local-LLM **agentic AI** workflow. Currently I have Gemma 4 E4B (other models work well too, but this one seems reliable and fast) as the LLM.\n\nIn testing my system, I found that a simple query, like \"summarize the Kimi-K3 blog post\" was slower than necessary because the agent had to **call multiple tools** to resolve the query. It had to find the date (with `find_blog_date`\n\nor similar) and then `read_blog_post`\n\n.\n\nI decided to try to **reduce** and **combine tool calls**—the `read_blog_post`\n\nMCP tool call could internally perform `find_blog_date`\n\n. The instructions on the tools would be updated to note the new calling pattern. So I could resolve a query with 1 tool call instead of 2 tool calls (and this also reduces thinking and token use).\n\nBasically, combining tool calls—such that a **single tool call** can resolve its own arguments—and not relying on the agent seems **beneficial** to **performance**. This makes the agentic AI workflow faster than before, reduces expensive GPU calls, and leads to greater user satisfaction.", "url": "https://wpnews.pro/news/reducing-tool-calls-in-agentic-ai", "canonical_source": "https://www.dotnetperls.com/2026_8_1_reducing-tool-calls-in-agentic-ai", "published_at": "2026-08-01 07:00:00+00:00", "updated_at": "2026-08-01 15:39:07.826211+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-agents", "ai-tools", "machine-learning"], "entities": ["Gemma 4 E4B", "Kimi-K3"], "alternates": {"html": "https://wpnews.pro/news/reducing-tool-calls-in-agentic-ai", "markdown": "https://wpnews.pro/news/reducing-tool-calls-in-agentic-ai.md", "text": "https://wpnews.pro/news/reducing-tool-calls-in-agentic-ai.txt", "jsonld": "https://wpnews.pro/news/reducing-tool-calls-in-agentic-ai.jsonld"}}
