Nexthop AI, which is focused on efficient AI networking, raised $500 million in a Series B round and is now valued at $4.2 billion. The round was led by Lightspeed Ventures and joined by Andreessen Horowitz and existing investors.

The company also launched switches designed for neoclouds and hyperscalers. Nexthop said the switches were part of its Disaggregated Spine architecture. The Broadcom-powered switches include NH-4010, NH-4220 and NH-5010. Those switches are engineered for scale-up and scale-out infrastructure, but the theme is that they are more efficient and save power.

Ahead of Oracle’s earnings report, the company put out a statement countering a Bloomberg article noting OpenAI pulled back on a deal because facilities didn’t have the latest Nvidia GPUs. Bloomberg reported that the companies ended plans to expand a data center in Abilene, TX. Oracle reportedly secured the site, ordered the hardware and spent on construction and staff with the expectation of expansion in the future.

Oracle shot back in a post on X and said the Bloomberg report, followed by CNBC, was false and incorrect. Oracle said existing projects were on track but didn’t address the expansion plans. Oracle said:

“Recent media activity about the Abilene site are false and incorrect. First, Crusoe and Oracle are operating in lockstep to deliver one of the world's largest AI Data centers in Abilene at record-breaking pace. Two buildings are completely operational and the rest of the campus is on track. Second, Oracle has completed leasing for the additional 4.5GW to deliver on our commitments to OpenAI.”

Constellation Research analyst Michael Ni on LinkedIn covered CData's Software's latest news and how it applies to moving AI from pilot to production. He also analyzed Nimble's latest round of funding.

Anthropic has sued the Department of War over a long running flap over using Claude in war scenarios where it is used autonomously and for surveillance of Americans.

In the lawsuit, Anthropic said:

"Anthropic brings this suit because the federal government has retaliated against it for expressing that principle. When Anthropic held fast to its judgment that Claude cannot safely or reliably be used for autonomous lethal warfare and mass surveillance of Americans, the President directed every federal agency to “IMMEDIATELY CEASE all use of Anthropic’s technology”—even though the Department of War (Department) had previously agreed to those same conditions."

Anthropic argues that the decision to make the company a supply chain risk to national security is "unprecedented and unlawful" and the Constitution doesn't allow the government to wield its enormous power to punish a company for its protected speech."

Anthropic vs. SaaS: A nuanced view

Anthropic released research that aims to be an early warning job loss detection system for AI-related job losses. The company is looking to close the gap between perceived job losses and what's actually happening with AI usage. It's worth a read.

Anthropic CEO Dario Amodei posted an update on where things stand with the Department of War. In a nutshell:

1. Anthropic said it will challenge the White House assessment that it is a supply chain risk in court.
2. Most existing Anthropic customers won't be affected.
3. The tone of the most was a bit apologetic and indicated that negotiations may be going on behind the scenes.
4. Anthropic models are being used in Iran as we speak.

"Our most important priority right now is making sure that our warfighters and national security experts are not deprived of important tools in the middle of major combat operations. Anthropic will provide our models to the Department of War and national security community, at nominal cost and with continuing support from our engineers, for as long as is necessary to make that transition, and for as long as we are permitted to do so."
