A Review of Federated Large Language Models for Industry 4.0
Industry 4.0 envisions a highly interconnected, autonomous manufacturing ecosystem enabled by the Industrial Internet of Things, Cyber-Physical Systems, and Artificial Intelligence. The emergence of large language models introduces new capabilities for semantic-aware decision-making, cross-domain knowledge integration, and intelligent automation. However, privacy, security, and regulatory constraints often isolate industrial data, impeding the scalability of LLMs in manufacturing. Federated learning addresses this by enabling decentralized LLM optimization without exposing raw data. This paper presents a comprehensive review of recent federated large language model research with a focus on industrial feasibility, comparing enabling techniques, system designs, and deployment strategies. Based on existing studies, forward-looking analyses are provided to highlight potential challenges and trade-offs in practical adoption, including computation and communication overheads, synchronization in large-scale federations, and system robustness. By bridging foundational methods with emerging industrial scenarios, we finally discuss the significant challenges associated with deploying federated large language models in complex industrial environments and outline a future research agenda.

Fed-LLM in Smart Manufacturing
Industry: Smart Manufacturing (Industry 4.0)
Challenge: Industrial data silos, privacy concerns, and limited generalization of ML models across heterogeneous production lines and factories.
Solution: Federated Learning (FL) for collaborative model training across different entities to support QC, improve productivity and product quality, and reduce costs. Use of Fed-LLM systems to enable decentralized LLM optimization.
Result: Improved QC, productivity, reduced costs, and enhanced model generalization across diverse factory environments without exposing raw data. High-precision anomaly detection with 97.2% accuracy in time-series data from equipment.
Future Research Directions for Fed-LLM in Industry 4.0
Industrial-Grade Lightweighting: Develop edge-computing-aware adaptive PEFT, expert selection mechanisms, and quantization-aware initialization to significantly reduce VRAM overhead and computational load for billions of parameters on resource-constrained industrial edge nodes.
Industrial Deep Heterogeneity: Focus on federated cross-domain semantic alignment with distillation techniques to extract generalizable knowledge representations (e.g., physical laws) across diverse industrial environments. This ensures global models capture universal mechanisms and align class-level representations across participants.
RAG-Enhanced Industrial Fed-LLM: Integrate retrieval-augmented generation (RAG) mechanisms to enable models to access external, non-parametric industrial knowledge dynamically. This approach addresses limitations in capturing rapidly changing, domain-specific knowledge while preserving data locality and reducing catastrophic forgetting.
Machine Unlearning & Continual Learning: Address the dual requirements of continual adaptation to evolving data distributions and regulatory compliance for machine unlearning on resource-constrained end devices. This ensures long-lifecycle operational stability and data sovereignty.
