When there are no laws meaningfully regulating military AI use, the Pentagon’s promise to use AI “lawfully” mean almost nothing. The authoritarian AI crisis has arrived www.platformer.news/anthropic-pe...

I want you to put the word out there that we back up.

Some day we'll all regret this & we'll hold hearings & rend garments & pledge "never again" & we'll be just as full of shit as we were last time.

Zentropi is now integrated into Coop, @roost.tools's open source moderation platform. You can write a content policy in plain English on Zentropi, plug it into Coop as a signal, and have a moderation pipeline running in minutes.

Zentropi Now Powers Coop Zentropi labelers can now be used as classifiers within Coop, ROOST's Open Source Moderation Platform

@dwillner.bsky.social and I have spent years watching T&S teams rebuild the same infrastructure from scratch. This is what it looks like when open tools actually work together instead. Really proud of this one and appreciative of @roost.tools's leadership!

@dwillner.bsky.social and @samidh.bsky.social have released open models for online safety, pushed transparency with their model cards, and made it easier for teams to kickstart their safety work with their policy labeler library. We're excited that they're now integrated with our review tool, Coop!

Cops are great

Also: guillotines are the moderate solution

Just as ICE and CBP have no legitimate role in "election security" neither does the head of DHS. The mere existence of this press conference should be a scandal, much less this tone-deaf comment.

All of my group chats are responding to Homan’s announcement by asking everyone to double down because:

1. ICE is still out there and abducting people today. We can’t trust the occupation is over until we actually see it.

2. People are going to be in an economic crisis for a very long time.

I do not wish to be mean, but if I hear you in the year 2026 claiming that Elon Musk "saved free speech" from "leftist censors" I am going to question your judgment on pretty much everything else, because you do not live in reality.

This is just insane. It’s only a matter of time before DHS kills another innocent person here.

Minneapolis should press its momentum and demand not only withdrawal but start talking about the need for immediate reparations, loudly, with the total certainty that only winners have. "You have wronged us terribly and must pay recompense" and let them argue the second part.

It's for sure a double edged sword. But there really is no such thing as social media (or any site hosting ugc) without content moderation. There are different ways to implement the outcomes (e.g. how this place gives you choice about which filters you opt into). But even X moderates (albeit badly).

This is so unhinged

The work @samidh.bsky.social and I are doing at Zentropi is a good public example of this (and the one I'm most able/at liberty to talk about) but there is so much happening in this space right now.

AI is Removing Bottlenecks to Effective Content Moderation at Scale Zentropi's Dave Willner says LLM-driven technology can now accomplish content classification at the scale necessary for moderation on large platforms.

@techpolicypress.bsky.social was kind enough to host my reflections on just how far we’ve already come with AI-assisted content moderation.

We’ve got a long way to go, but the difficulties that used to serve as (legitimate) excuses are fading fast.

Scrolling through the photos of Pam Bondi's "Minnesota rioters," it's just hero after hero. Every photo includes a cowardly DHS agent with their back to the camera.

Bondi thinks she's going to win the propaganda war with this shit, but it's never been more clear that they're losing.

People not in Minneapolis spreading the theory that Pretti was targeted in a hit do not understand the damage they’re potentially doing. Insanely irresponsible

27.01.2026 23:09 👍 1019 🔁 125 💬 10 📌 6

Guys maybe the number one obstacle to organizing here in Minneapolis is the unfounded fear that if you get involved, DHS will put you on a list and assassinate you. It leads people to avoid organizing or act in ways that are completely detrimental to organizing. Please please do not spread that fear

Yep, the shootings were clearly great politics for the White House just like the White House said.
