arXiv:2605.07961v2 Announce Type: replace Abstract: Federated fine-tuning (FFT) has emerged as a privacy-preserving paradigm for collaboratively adapting large language models (LLMs). Built upon federated learning, FFT enables distributed agents to jointly refine a shared pretrained LLM by aggregating local LLM updates without sharing local raw data. However, FFT-based LLMs remain vulnerable to model manipulation threats, in which adversarial participants upload manipulated LLM updates that corrupt the aggregation process and degrade the performance of the global LLM. In this paper, we propose
The increased deployment of federated learning for LLM fine-tuning necessitates advanced security measures against adversarial attacks to ensure model integrity and privacy as these systems become more widespread.
Sophisticated readers should care because securing federated fine-tuning processes is critical for the trustworthy and scalable adoption of AI, particularly in sensitive sectors, preventing data poisoning and model degradation.
The focus is shifting towards more robust and provably secure methods for collaborative LLM training, acknowledging and actively countering inherent vulnerabilities in distributed AI paradigms.
