.@amazon has believed in giving customers choice across AI models for years. We have always supported open-weight models on Amazon Bedrock, starting back in 2023, and will continue to advocate for open ecosystems. No single model will define AI leadership. Customers need access to the most capable frontier models, alongside open-weight models they can adapt, optimize, and deploy for their own workloads. Open and closed models are complementary. Together, they expand access to AI, accelerate innovation, strengthen competition, and give organizations greater control over the technology they build. Successful leadership in AI will not be built around a single model or a single approach. It will be built on broad choice and the infrastructure to run those models securely, reliably, and at scale. While there are elements of the Open Weights and American AI Leadership letter that need further definition over time, we’re supportive of the macro direction and have signed it.


There’s been a lot of speculation about where we stand on open-weights models. We’ve outlined our views in full here: anthropic.com/news/position-…







Attackers have frontier AI. Defenders need a frontier AI ecosystem—the best open and closed models, force-multiplied by a global community. During the Hugging Face incident, closed AI blocked essential forensics. An open-weight frontier model helped contain the intrusion. That’s why we created the Open Secure AI Alliance.
