Amazon has opened Project Rainier, an $11 billion AI data center in Indiana, designed to train its AI models using custom chips. The facility is already operational, with plans for extensive expansion amid rising demand for AI computing power. Local concerns about farmland loss and increased energy costs accompany the project's rapid development.

Keith Heyde, newly appointed head of infrastructure at OpenAI, is leading the search for sites to build the company’s next-generation data centers, aimed at supporting the training of advanced AI models. With around 800 proposals received, about 20 sites are in advanced review, focusing on factors like power access and community support rather than just tax incentives. OpenAI's ambitious expansion includes a significant partnership with Nvidia, which is investing up to $100 billion to support the infrastructure needed for AI development.
