A free, unattributed model called Hunter Alpha appeared on OpenRouter, which the platform labeled a stealth model. Its profile advertised roughly 1 trillion parameters, a 1M-token context window, reasoning capability and free access — a combination Reuters noted matched widely reported expectations for DeepSeek's unreleased V4.

It rapidly topped OpenRouter's daily usage charts, passing 500 billion tokens in its first week. At the time nobody had claimed it; Xiaomi's MiMo team later confirmed it was an early internal test build of MiMo-V2-Pro, its flagship agent model.

Google LLC completed its $32 billion all-cash acquisition of cloud and AI security platform Wiz, a year after announcing it and following US DOJ clearance in November 2025 and unconditional EU approval on February 10, 2026.

Wiz joins Google Cloud but keeps its brand and its commitment to securing AWS, Azure and Oracle Cloud environments. Wiz had crossed $1 billion in ARR in 2025, roughly double the run rate at the time of Google's first, rejected $23 billion approach. The close makes it both the largest acquisition in Google's history and the largest-ever acquisition of a venture-backed startup.

NVIDIA and Mira Murati's Thinking Machines Lab announced a multi-year strategic partnership to deploy at least one gigawatt of next-generation Vera Rubin systems for frontier model training, with deployment targeted for early next year.

NVIDIA also made a significant undisclosed investment in the startup, and the two will co-design training and serving systems for NVIDIA architectures. At NVIDIA's own stated ~$50B-per-gigawatt figure, the compute commitment alone is worth tens of billions.

Anthropic filed two lawsuits against the Pentagon — one in the Northern District of California and one at the DC Circuit Court of Appeals — challenging the Department of War's designation of the company as a supply chain risk to national security.

The fight stems from Anthropic's refusal to drop two contractual red lines: no domestic mass surveillance and no fully autonomous lethal targeting. The designation, formalized in a March 4 letter, was the first time the tool had been aimed at a US company, and it threatened to force any government contractor doing business with the Pentagon to cut ties with Anthropic. Anthropic argues the move violates the First Amendment and is an arbitrary abuse of procurement authority; government filings later claimed concern that Anthropic might preemptively alter Claude's behavior mid-warfighting.

Advanced Machine Intelligence Labs, the Paris-based startup co-founded by Turing Award winner Yann LeCun after he left Meta in November, closed a $1.03 billion seed round at a $3.5 billion pre-money valuation.

The round was co-led by Cathay Innovation, Greycroft, Hiro Capital, HV Capital and Bezos Expeditions, with Nvidia, Mark Cuban, Eric Schmidt and Tim Berners-Lee among the backers. AMI is building world models on LeCun's JEPA approach — systems that learn from real-world sensor data rather than text — and is hiring across Paris, New York, Montreal and Singapore. LeCun has said the lab will be one of the few frontier labs that is neither Chinese nor American.
