Monthly Roundup #40: March 2026

It is that time again.

After events surrounding Anthropic and the Department of War, I plan on taking full advantage of whatever lulls I can get. Things are only going to move faster over time.

That means a higher bar for coverage, and it means potentially skipping more days, or using those days for short posts that either spin off fun little things or that embody concepts I want to refer back to over time.

In the meantime, here’s everything that doesn’t go anywhere else, and that does not want to fully stand on its own.

AI #159: See You In Court

The conflict between Anthropic and the Department of War has now moved to the courts, where Anthropic has challenged the official supply chain risk designation as well as the order to remove it from systems across the government, claiming retaliation for protected speech. It will take a bit to work its way through the courts.

Anthropic has the principles of law on its side, a maximally strong set of facts and absurdly strong amicus briefs. If Anthropic loses this case, there will be far reaching consequences for our freedoms.

Let us hope this remains in the courts and is allowed to play out there, and then ultimately that negotiations can resume and the parties can at least agree on a smooth transition to alternative service providers. If DoW wants an otherwise full deal more than it wants the right to use Claude to monitor Americans and analyze their data, a full deal is possible as well, but if they demand full ‘all lawful use,’ all trust has been lost or they are or always were out to hurt Anthropic, then there is no deal or ZOPA.

GPT-5.4 Is A Substantial Upgrade

Benchmarks have never been less useful for telling us which models are best.

They are good for giving a general sense of the landscape. They definitely paint a picture. But if you’re comparing top models, like GPT-5.4 against Opus 4.6 against Gemini 3.1 Pro, you have to use the models, talk to the models, get reports from those who have and form a gestalt. The reports will contract each other and you have to work through that. There’s no other way.

Thus, I try to gather and sort a reasonably comprehensive set of reactions, so you can browse the sections that make you most curious.

Claude Code, Claude Cowork and Codex #5

It feels good to get back to some of the fun stuff.

The comments here can double as a place for GPT-5.4 reactions, in addition to my Twitter thread. I hope to get that review out soon.

Almost all of this will be a summary of agentic coding developments, after a note.

Anthropic Officially, Arbitrarily and Capriciously Designated a Supply Chain Risk

Make no mistake about what is happening.

The Department of War (DoW) demanded Anthropic bend the knee, and give them ‘unfettered access’ to Claude, without understanding what that even meant. If they didn’t get what they want, they threatened to both use the Defense Production Act (DPA) to make Anthropic give the military this vital product, and also designate the company a supply chain risk (SCR).

Hegseth sent out an absurdly broad SCR announcement on Twitter that had absolutely no legal basis, that if implemented as written would have been corporate murder. They have now issued an official notification, which is still illegal, arbitrary and capricious, but is scoped narrowly and won’t be too disruptive.

AI #158: The Department of War

This was the worst week I have had in quite a while, maybe ever.

The situation between Anthropic and the Department of War (DoW) spun completely out of control. Trump tried to de-escalate by putting out a Truth merely banning Anthropic from direct use by the Federal Government with a six month wind down. Then Secretary of War Hegseth went rogue and declared Anthropic a supply chain risk, with wording indicating an intent to outright murder Anthropic as a company.

Then that evening OpenAI signed a contact with DoW,

I’ve been trying to figure out the situation and help as best I can. I’ve been in a lot of phone calls, often off the record. Conduct is highly unbecoming and often illegal, arbitrary and capricious. The house is on fire, the Republic in peril. I have people lying to me and being lied to by others. There is fog of war. One gets it from all sides. It’s terrifying to think about what might happen with one wrong move.

Gemini 3.1 Pro Aces Benchmarks, I Suppose

I’ve been trying to find a slot for this one for a while. I am thrilled that today had sufficiently little news that I am comfortable posting this.

Gemini 3.1 scores very well on benchmarks, but most of us had the same reaction after briefly trying it: “It’s a Gemini model.”

And that was that, given our alternatives. But it’s got its charms.

Consider this a nice little, highly skippable break.

The Pitch

It’s a good model, sir. That’s the pitch.

Sundar Pichai (CEO Google): Gemini 3.1 Pro is here. Hitting 77.1% on ARC-AGI-2, it’s a step forward in core reasoning (more than 2x 3 Pro).

With a more capable baseline, it’s great for super complex tasks like visualizing difficult concepts, synthesizing data into a single view, or bringing creative projects to life.

We’re shipping 3.1 Pro across our consumer and developer products to bring this underlying leap in intelligence to your everyday applications right away.

A Tale of Three Contracts

The attempt on Friday by Secretary of War Pete Hegsted to label Anthropic as a supply chain risk and commit corporate murder had a variety of motivations.

On its face, the conflict is a tale of three contracts and the associated working relationships.

  1. The contract Anthropic signed with the Department of War (DoW) in 2025.
  2. The new contract Anthropic was negotiating with DoW, that would have been modified to favor DoW, but where the parties could not reach agreement.
  3. The contract OpenAI was negotiating and signed with DoW, which was per OpenAI modified favorably to OpenAI and thus may be modified further.

Secretary of War Tweets That Anthropic is Now a Supply Chain Risk

This is the long version of what happened so far. I will strive for shorter ones later, when I have the time to write them.

Most of you should read the first two sections, then choose the remaining sections that are relevant to your interests.

But first, seriously, read Dean Ball’s post Clawed. Do that first. I will not quote too extensively from it, because I am telling all of you to read it. Now. You’re not allowed to keep reading this or anything else until after you do. I’m not kidding.

That’s out of the way? Good. Let’s get started.

Anthropic and the DoW: Anthropic Responds

The Department of War gave Anthropic until 5:01pm on Friday the 27th to either give the Pentagon ‘unfettered access’ to Claude for ‘all lawful uses,’ or else. With the ‘or else’ being not the sensible ‘okay we will cancel the contract then’ but also expanding to either being designated a supply chain risk or having the government invoke the Defense Production Act.

It is perfectly legitimate for the Department of War to decide that it does not wish to continue on Anthropic’s terms, and that it will terminate the contract. There is no reason things need be taken further than that.
