Unextractable Protocol Models: Collaborative Training and Inference without Weight Materialization
arXiv:2605.23464v1 Announce Type: new Abstract: We consider a decentralized setup in which the participants collaboratively train and serve a large neural network, and where each participant only processes a subset of the model. In this setup, we explore the possibility of unmaterializable weights, where a full weight set is never available to any one participant. We introduce Unextractable Protocol Models (UPMs): a training and inference framework that leverages the sharded model setup to ensure model shards (i.e., subsets) held by participants are incompatible at different time steps.

The increasing scale and resource demands of large AI models, coupled with growing concerns over intellectual property and data sovereignty, are driving innovation in decentralized and secure AI architectures.
This development offers a potential pathway to collaboratively train and use powerful AI models while mitigating risks of centralized control, intellectual property theft, and data exposure.
The ability to train and infer with AI models whose complete weights are never materialized by a single entity fundamentally alters current approaches to model security, distribution, and governance.
- · Decentralized AI platforms
- · Sensitive data industries
- · Sovereign AI initiatives
- · Developers of privacy-preserving AI
- · Centralized model providers relying on full weight access
- · Actors seeking to extract or reverse-engineer full models
- · Undifferentiated cloud AI services
Secure, collaborative AI development becomes more feasible, allowing greater participation from distrusting parties.
New business models emerge for AI services that do not require full model access, fostering a more distributed AI ecosystem.
The concept of 'model ownership' or 'model materialization' could become less relevant as AI intelligence is distributed across unextractable components, impacting regulatory frameworks and intellectual property definitions.
