CNBC's MacKenzie Sigalos reports on news regarding recent AI models.

Anthropic has introduced Opus 4.5, its most powerful AI model to date, designed for advanced coding, enterprise workflows, and financial modeling. The model includes new tools for Excel and Chrome, as well as an 'infinite chat' feature to enhance long conversations without memory cutoffs. 

The launch coincides with Anthropic's commitment to invest over $80 billion in computing infrastructure over the next decade, including partnerships with Microsoft Azure and new U.S. data centers. Meanwhile, Amazon announced plans to invest up to $50 billion in AI and supercomputing capacity for U.S. government cloud customers, while Google’s Gemini 3 model continues to lead industry benchmarks.

Anthropic launches Claude Opus 4.5

We've also got some news out of Amazon as well. These are the kind of headlines that can and often do move stocks. So let's hit them both. Mackenzie Cigalos is out in San Francisco starting with some breaking news on Anthropic. Hey Brian. So Anthropic is launching its most powerful model yet. It's called Opus 4.5 and it is the new flagship of the Claude family built for advanced coding agentic workflows and enterprise tasks like financial modeling. The update includes new Excel and Chrome tools and a feature called infinite chat that prevents memory cutoffs in long conversations. And it comes as Anthropic commits more than 80 billion dollars to compute over the next decade including a new spend commitment with Microsoft Azure and its own custom made data centers across the United States. But in terms of this model race some would argue that Anthropic's chief rival is now Google. Gemini 3. It hit the top of the benchmarks last week. Salesforce's Mark Benioff said he would never go back to chat GBT after using Gemini 3. So we're really seeing this rivalry heat up. Brian. Yeah it really is. It's pretty amazing to watch all the investment that's going on into this as well. Let's pivot now. Anthropic is obviously private. Amazon is not. I mean the numbers just keep coming out. Amazon talk about 50 billion investing in A.I. but I never know. Mackenzie maybe you do. Are these new numbers or do we hear the same headlines about the same numbers kind of over and over again. So in the case of this Amazon announcement this morning it's additive to existing commitments. So we knew that they had that 11 billion dollar data center created exclusively for Anthropic in northern Indiana and then another 38 billion dollars with open A.I. But now today what they are talking about is planning to invest up to 50 billion dollars to build out A.I. and supercomputing capacity exclusively for its U.S. government cloud customers. Now that project is meant to break ground in 2026. It's going to add nearly one point three gigawatts of capacity through its new A.W.S. data centers built for classified workflows. And as you know that's roughly enough to power a million homes here. And one other thing I'll say about this as part of the expansion federal agencies are going to get access to Amazon's full suite of A.I. tools including anthropics cloud models.
