An open letter to Dario: if you mean it, open the weights
summary
The author argues that the only way to truly slow the development of frontier AI models is to mandate that any model released to the public be open weights. By removing the proprietary nature of weights, the financial incentive for massive training runs is diminished because valuations based on proprietary secrets are no longer possible. This approach avoids the regulatory capture that typically follows government-mandated safety evaluations and compute thresholds. It leverages the own mission-driven structure of companies like Anthropic to prioritize long-term safety over short-term profit.
key points
- Regulatory capture is inevitable when industry leaders help write the laws that protect their own market position through complex compliance requirements.
- Mandating open weights for public models would crash the proprietary valuations of AI labs, effectively reducing the available capital for future training runs.
- Dario Amodei of Anthropic is uniquely positioned to propose this law because his company's PBC status allows him to prioritize humanity's benefit over shareholder profit.

top insight
The author proposes a US law requiring model weights to be open if a company sells model access, aiming to 'destroy the game' by removing the profit incentive for massive training runs. This 'decelerationist' strategy seeks to slow frontier AI progress by restricting the return on capital, rather than attempting to regulate research itself. Supporters argue it creates a level playing field, while critics claim it would simply push development offshore to jurisdictions like China and destroy US competitiveness.
