Last September, Amazon and Anthropic announced a strategic collaboration, which included Anthropic naming Amazon Web Services, or AWS, its primary cloud provider and Amazon making a $4B investment in Anthropic. "That announcement was underpinned by the rapid adoption of the Claude family of models on AWS, following its addition to Amazon Bedrock in April of last year. Today, Amazon and Anthropic are deepening their collaboration. Anthropic is now naming AWS its primary training partner, in addition to continuing to be its primary cloud provider, and will use AWS Trainium and Inferentia chips to train and deploy its future foundation models. Both companies will continue to work closely to keep advancing Trainium's hardware and software capabilities. This next phase of the collaboration will even further enhance the already premium performance, security, and privacy Amazon Bedrock provides for customers running Claude models.
