Review outlines ten foundational challenges in federated foundation models across data, heterogeneity, and efficiency, highlighting critical pathways toward robust, privacy-preserving AI.

Key Points

To establish a comprehensive taxonomy and mathematical formulation of the ten major open challenges facing federated foundation models across distributed learning environments.
Categorized distributed foundation model constraints into five domains: foundational theory, data, heterogeneity, security and privacy, and efficiency.
Formulated mathematical objective functions for core operational problems including bidirectional knowledge transfer, machine unlearning, and non-IID graph processing.
Synthesized current algorithmic approaches, identifying architectural bottlenecks across client-server teacher-student learning settings.
Identified critical theoretical gaps in unifying federated learning with massive foundation models, particularly in managing heterogeneous client compute and communication resources.
Demonstrated that private domain adaptation requires novel mechanisms for bidirectional knowledge transfer, data unlearning, and intellectual property defense via model watermarking.
Characterized fundamental trade-offs between parameter-efficient fine-tuning, decentralized communication constraints, and collaborative game-theoretic incentive structures.
