FedSkillGit: Federated Skill Evolution via Version Control

FedSkillGit is a federated framework that enables large language model agents to evolve reusable natural‑language skills without sharing raw data. Instead of uploading entire skill documents, clients submit bounded patches and local experience summaries, which are filtered for privacy, deduplicated, and merged into a global skill candidate. The server distributes the candidate for client‑side validation, publishing it only when performance improves, and experiments show it outperforms baselines by up to 22% while approaching centralized results.

Vision Paper: Why Distributed LLM Post-Training and Decentralized Alignment Are Now Essential

The paper argues that distributed learning—federated and decentralized—should be a core approach for large language model post‑training, rather than an optional privacy measure. It critiques current methods like RLHF and DPO for assuming centralized preference data, citing scientific, practical, and ethical flaws. The authors present a three‑pillar framework (privacy and data sovereignty, pluralism and representational equity, robustness and scalability), formalize technical challenges such as reference drift and preference heterogeneity, and outline algorithmic directions and a research agenda to make distributed post‑training feasible.
