Amazon has made a significant investment of $2.75 billion in the artificial intelligence startup Anthropic. This latest investment brings Amazon's total stake in the San Francisco-based company to $4 billion. The initial investment of $1.25 billion was made in September, and the recent infusion completes the commitment Amazon made at that time to invest up to $4 billion in Anthropic.

Anthropic is known for its generative AI and the Claude 3 family of models, which demonstrate advanced intelligence, near-human levels of responsiveness, improved steerability and accuracy, and new vision capabilities. These models are accessible on Amazon Bedrock, a fully managed service provided by Amazon Web Services (AWS). As part of the agreement between the two companies, Anthropic is using AWS as its primary cloud provider and will utilize AWS Tranium and Inferentia chips for its future AI models. Additionally, Anthropic has made a long-term commitment to provide AWS customers with access to future generations of its foundation models on Amazon Bedrock.
