Introducing Hy4 Preview

Tencent released Hy4 Preview, an open-weight text-only LLM with 770B total parameters, 49B active, a 1M token context window, and 1.56TB of weights on Hugging Face. It's a large jump from Hy3, released in July at 295B total parameters, 21B active, and a 256,000 token context.

Tencent's jump from Hy3 in July (295B total, 21B active, 256K context) to Hy4 now (770B total, 49B active, 1M context) is a fast iteration cycle, and that pace is what people building agent stacks on open weights should track.

The US military gets its own ChatGPT today

The Pentagon added an OpenAI product to its list of AI tools approved for unclassified work today, after months of security testing.

Getting added to the approved vendor list is a procurement milestone. How fast DoD teams actually integrate it into workflows, versus just checking a compliance box, will decide whether it matters.

Stop Using AI. Start Commanding It

A War on the Rocks piece argues DoD's AI push, which drove GenAI.mil to 1.5 million users in six months, focuses on 'using' tools rather than 'commanding' forces. It points to a task force operating out of a Maryland basement that collects intelligence, develops missions, and executes against targets around the clock.

This is the right critique. Rolling out chat interfaces to a million users measures adoption. It says nothing about operational advantage, and that gap is where budgets get wasted.

Federal Judge Rules Pentagon's 'Supply Chain Risk' Designation of Anthropic Was Unlawful

A federal judge ruled that Defense Secretary Pete Hegseth's designation of Anthropic as a national-security supply chain risk was unlawful, calling it First Amendment retaliation and a due process violation. The designation followed Anthropic's refusal to let the Pentagon use its models for fully autonomous weapons or mass surveillance.

A court just confirmed that an AI lab can say no to autonomous weapons and mass surveillance use cases without the government punishing it through a supply chain label, a meaningful precedent for every lab drafting usage policies.

With AI hackers in mind, Air Forces Cyber develops defensive ‘campaign plan’

Air Forces Cyber is developing a defensive 'campaign plan' to counter AI-enabled hacking threats. 16th Air Force commander Lt. Gen. Thomas Hensley said the service is at an inflection point regarding AI threats to its networks.

Calling this an inflection point is easy; the campaign plan will only matter once there's a public account of what it actually changes about how the Air Force defends its networks.

Army will soon deliver first batch of detection tools to help command posts identify their own signal emissions, protect from EMS targeting

The Army will deliver nine Spectrum Situational Awareness Systems to prioritized units within three weeks. The systems help command posts identify their own signal emissions to protect against electromagnetic spectrum targeting.

Detecting your own emissions before the enemy does is unglamorous EW hygiene, and actual fielding matters more than most announcements in this space.

After back-to-back airspace blunders earlier this year, border task force shoots down ‘cartel-linked’ drones with AV laser

Joint Task Force-Southern Border used the Army Multipurpose High Energy Laser system to engage three 'hostile' drones described as cartel-linked over two days, according to a press release. The engagements follow earlier airspace incidents this year.

This laser counter-UAS engagement on the southern border is a bigger deal than the headline treats it as. Whether this becomes routine or stays a one-off is the open question.

Can AI help the Marines simplify sustainment in the Pacific?

The Marine Corps is testing a 'logistics decision engine' at the theater level to help simplify sustainment in the Pacific.

Pacific logistics is a real operational bottleneck for the Marine Corps, so an AI tool aimed at that problem is a more consequential use case than most of the chatbot rollouts getting attention.
