Amazon has signed the Nvidia-Microsoft open-weights letter, leaving Anthropic as the lone holdout among the companies being discussed in the thread.
The cited Amazon statement says the company supports customer choice across AI models, has backed open-weight models on Bedrock since 2023, and will keep advocating for open ecosystems. It argues that open and closed models are complementary, and that AI leadership will not be built around a single model or approach.
