Amazon will invest another $4 billion in Anthropic to bring its total investment to $8 billion. Anthropic will also use AWS as its primary training partner and use AWS Trainium and Inferentia processors to deploy its largest large language models.

The latest Amazon investment comes shortly after Anthropic landed a partnership with Snowflake.

Amazon's first investment in Anthropic made the company's Claude family of models a headliner on Amazon Bedrock. The latest Amazon investment makes Anthropic a closer partner.

In a statement, the companies said they will "will continue to work closely to keep advancing Trainium's hardware and software capabilities."

The companies added: "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."

As previously noted, the Amazon-Anthropic partnership is notable since OpenAI is tightly aligned with Microsoft. Google also offers Anthropic models and many others in addition to its Gemini family of LLMs. What has emerged is spheres of LLM influence around hyperscale cloud providers. Meta has Llama and is focused on open source options with potential business applications in the future.
