Agentic AI in Manufacturing: Why General-Purpose LLMs Fail

This title was summarized by AI from the post below.

Why do most Agentic AI projects fail in manufacturing? I joined Kudzai Manditereza at the Industry40tv podcast to discuss why general-purpose LLMs aren't enough for the shop floor. To move from "chatbots" to true Decision Intelligence, you need a system that understands cause-and-effect in physical processes. We dive deep into the 3-layer architecture we’re building at EthonAI to make agentic workflows reliable at scale. Thanks for the great conversation, Kudzai! Links in comments! 👇

Agentic AI can transform how manufacturers make decisions. But not in the way most people think. The real promise isn't chatbots on the shop floor or copilots summarizing dashboards. It's decision intelligence. AI agents that can investigate a quality failure, trace the root cause across systems, and tell an operator exactly which lever to pull right now for a better outcome. That's the vision. But here's the problem: Most agentic workflows today are built on top of general-purpose LLMs that have no understanding of cause and effect in physical processes. To build agentic workflows that can reliably reason at scale, you need a three-layer architecture: 𝟏. 𝐃𝐚𝐭𝐚 & 𝐈𝐧𝐟𝐫𝐚𝐬𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞 𝐋𝐚𝐲𝐞𝐫 This layer combines streaming data infrastructure (MQTT, Kafka, UNS) with a process knowledge graph that models how your production actually runs. 𝟐. 𝐌𝐨𝐝𝐞𝐥 𝐋𝐚𝐲𝐞𝐫 This is where causal reasoning lives. Purpose-built models that understand time series, respect safety limits, and can trace cause-and-effect chains across your process. 𝟑. 𝐀𝐩𝐩𝐥𝐢𝐜𝐚𝐭𝐢𝐨𝐧 𝐋𝐚𝐲𝐞𝐫 This is where the agentic workflows operate. The agent orchestrates by pulling data from the infrastructure layer, calling the right causal model, and reading SOPs and process documentation. Synthesizing everything into a clear, operator-ready recommendation that can be trusted and acted on. When this architecture is in place, agentic AI delivers real decision intelligence. In this episode of the AI in Manufacturing podcast, I speak with Bernhard Kratzwald, Co-Founder and CTO at EthonAI, about building and scaling agentic AI workflows for optimizing cost, quality, and speed in manufacturing operations.

That gap between “having the equipment” and “knowing how to use it” is what I call the process knowledge gap.Knowledge can’t be downloaded. It can only be built. Giving someone a professional kitchen and a recipe book doesn’t make them a chef. https://www.linkedin.com/feed/update/urn:li:ugcPost:7444293194936131584/
