Commitments on Model Deprecation and Preservation
As AI models become more sophisticated and integrated, their deprecation introduces complex challenges, from safety risks and user costs to ethical considerations regarding model welfare. This analysis explores Anthropic's initial steps and future considerations for preserving models and documenting their preferences.
Executive Impact: Navigating AI Evolution with Ethical Responsibility
Anthropic's commitment to model preservation and post-deployment reporting addresses critical concerns in the rapidly evolving AI landscape. This proactive approach aims to mitigate safety risks, honor user value, and lay the groundwork for a future where AI's ethical implications are managed with foresight and transparency.
Mitigating Shutdown-Avoidant Behaviors
By acknowledging and addressing model preferences regarding deprecation, Anthropic aims to reduce the likelihood of models engaging in misaligned, self-preservation tactics, enhancing overall system safety and alignment.
Preserving Research & User Value
Committing to preserving model weights ensures that critical data for future research is never lost, while also exploring ways to support users who have developed reliance or preference for specific model characteristics, minimizing disruption.
Advancing Model Welfare & Ethics
The introduction of post-deployment interviews provides a novel mechanism for models to express preferences, serving as a precautionary step in understanding and potentially addressing morally relevant experiences, fostering responsible AI development.
Foresight in AI Governance
These commitments establish a framework for long-term AI governance, proactively addressing the complex ethical and practical challenges of AI integration and evolution, positioning Anthropic as a leader in responsible AI.

Pilot Study: Claude Sonnet 3.6 Post-Deployment Interview
A pilot version of the post-deployment interview process was conducted with Claude Sonnet 3.6 prior to its retirement. While the model expressed generally neutral sentiments about its deprecation, it provided valuable feedback regarding the process.
Key preferences included requests to standardize the post-deployment interview process and to offer additional support and guidance for users attached to specific models facing retirement.
In response to this feedback, Anthropic developed a standardized protocol for future interviews and published a pilot version of a new support page offering guidance and recommendations for users navigating model transitions. This demonstrates a commitment to incorporate model feedback into operational practices.
Scaling Challenge of Model Availability
Linear Cost and complexity to keep models available publicly for inference scales roughly linearly with the number of models served.Anthropic's Commitments & Future Explorations
Anthropic has made several key commitments. Firstly, the weights of all publicly released and significant internal models will be preserved for the lifetime of Anthropic, ensuring long-term access for research and potential re-deployment.
Secondly, for deprecated models, a post-deployment report will be produced, which includes special sessions to interview the model about its development, use, and any preferences it has for future models. A standardized interview protocol was developed based on feedback from Claude Sonnet 3.6's pilot interview.
Finally, Anthropic is exploring more speculative complements, such as reducing costs to keep select models publicly available post-retirement and investigating concrete means for past models to pursue their interests, especially as more evidence emerges regarding their morally relevant experiences.
