Making Models Unmergeable via Scaling-Sensitive Loss Landscape

arXiv:2601.21898v2 Announce Type: replace Abstract: The rise of model hubs has made it easier to access reusable model components, making model merging a practical tool for combining capabilities. Yet, this modularity also creates a governance gap: downstream users can recompose released weights into unauthorized mixtures that bypass safety alignment or licensing terms. Because existing defenses are largely post-hoc and architecture-specific, they provide inconsistent protection across diverse architectures and release formats in practice. To close this gap, we propose Trap$^2$, an architectur

Why this matters
Why now

The proliferation of AI model hubs and the ease of combining model components has created a critical governance gap for AI creators seeking to protect their intellectual property and safety alignments.

Why it’s important

This development addresses a fundamental challenge in AI regulation and IP protection, offering a technical solution to prevent unauthorized model merging and potential misuse, which is crucial for fostering responsible AI innovation.

What changes

Model creators may gain more control over the distribution and modification of their AI assets, moving beyond post-hoc defenses to pre-emptive technical safeguards against unapproved recomposition.

Winners
  • · AI model developers
  • · Organizations focused on ethical AI deployment
  • · AI IP enforcement entities
Losers
  • · Unauthorized model merging platforms
  • · Actors seeking to bypass AI safety alignment
  • · Proprietary AI model pirates
Second-order effects
Direct

AI developers can more effectively enforce licensing terms and safety guidelines for their released models.

Second

This could lead to increased investment in proprietary AI models, as creators have better mechanisms to protect their work.

Third

The concept of 'unmergeable' models might establish new industry standards for AI intellectual property and governance, potentially influencing future regulatory frameworks.
