.@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.
