Banning all teens from social media hasn't ever seemed like a great idea to me. A much healthier approach is for platforms to build smoother on-ramps for teens that are developmentally appropriate for each child's age. 🧵 [1/n]...

I continue to be impressed with Zentropi. My first thought is that they were a replcement for Perspective API that Jigsaw was ending. And yes, but so much more. So far they can answer virtually any question about a text of almost any size my work cares about that CAN be answered with a Yes or a No.

Today, in a single day, @dwillner.bsky.social and I had meetings with people in England, Turkey, NYC, SF, Argentina, and Australia. Very inspiring to see four continents of folks all using Zentropi and united in the earnest work of building a better internet.

I distinctly remember being at Meta in the wake of the Christchurch massacre, when horrific videos were circulating across Facebook without end. The technologies we had for being able to accurately classify videos just didn't exist. [1/n]

Today we're releasing Coop 1.0, the world's first free, open source content review & enforcement system any org can self-host and build on. For the first time, any org, whatever its size or budget, can review, act on, and report CSAM end to end, for free. roost.tools/blog/coop-1-...

Coop 1.0: World’s First Free, Open Source Child Safety Infrastructure for Every Platform

Robust Open Online Safety Tools or ROOST is a new non-profit entity designed to address the urgent need for accessible, high-quality safety tools in the rapidly evolving digital landscape.

Very cool! @julietshen.bsky.social's independent tests show that our new model CoPE-B cooks :-) Direct link to her results: github.com/julietshen/c...

I am NOT an AI engineer or AI researcher, but I tried to do a little evaluation of CoPE-B vs CoPE-A vs gpt-oss-safeguard github.com/roostorg/mod... lmk what you think, and we'd love for more evaluations to be part of the ROOST Model Community! cc @samidh.bsky.social

The ROOST Model Community is growing! Today we welcome Zentropi's CoPE-B-A4B, a bring-your-own-policy model that's got the power of 25B but runs on only 4B active parameters. It's a fast, low-cost model that can be used on its own or as a first pass before larger models! roost.tools/blog/welcomi...

a few use cases I can think of for CoPE-B (and BYOP models): if you're a platform that's ok with NSFW role play but not age play, you can create a custom CoPE model that looks just for that. Many free text classifiers come with baked-in ideas of morality that might not fit your community

We're releasing CoPE-B in collaboration with @roost.tools and will support it through the ROOST Model Community. It's a great forum for advancing AI-powered trust & safety tooling and we're excited to be a part of it. We'll be active there if you're building with CoPE-B and have questions! 🧵 9/9

We are THRILLED to announce that @roost.tools is jointly releasing CoPE-B with the Zentropi team. We believe that everyone should have access to openly licensed models designed for safety use cases that can be tuned to their community's norms. Join us at RMC office hours next week to learn more!

Super pumped to release CoPE-B, our latest policy-adaptive content classification model. It delivers frontier-level accuracy in a self-hostable package that's orders of magnitude cheaper to run-- opening up new possibilities in trustworthy platform design. Details: blog.zentropi.ai/meet-cope-b-...

One of the things we've been thinking about a lot at Zentropi is: what happens when AI agents need to make judgment calls about content — not humans reviewing a queue, but agents acting autonomously?

There's a major gap in content safety tooling: classifiers typically only score complete text. When you're working with generative AI, "complete text" means the user already saw it. That's too late. So we built a streaming classifier that we're releasing today! Here's what we did and why. 🧵...

If you're not using either tool yet, now's a good time to try both! Zentropi's Community Edition is free and gives you unlimited labelers. Coop is fully open source and runs on your infrastructure. :D

@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! Details: blog.zentropi.ai/zentropi-now...

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.

Dave Willner, who led trust and safety at major tech firms and has cofounded a company that is developing an AI content classification platform, says LLM-driven technology can now accomplish classification at the scale necessary for moderation on large platforms. That has substantial implications.

Just shipped Zentropi's most requested feature: image classification! Now analyze images against your own policies, at scale. To power it we built cope-b-12b, a new multimodal model w/ native vision. Check out the cat detector we made in < 1 min. 🐱 blog.zentropi.ai/zentropi-now-labels-images/

Building guardrails for visual content just got a lot easier. Today we're launching image classification on Zentropi and announcing cope-b-12b, a multimodal model that powers this experience.

Why are we just giving away all our secrets? Well, it is our hope that it helps the ecosystem further advance the state of the art in policy-steerable content classification, which is foundational to a more trustworthy internet.

We just published the methodology behind CoPE, our 9B parameter model that matches GPT-4o at content classification at 1% the size! The model is already open source, but now we're sharing our training technique. blog.zentropi.ai/how-we-built... 🧵 1/6

Dave just published a Zentropi labeler that can precisely identify requests at prompting an AI model to undress a person in a photo. The tools exist to easily deal with this problem -- platforms just need to choose to use them. If you are the developer of an AI system, please use this guardrail!

Dave Willner@dwillner.bsky.social · 7mo ago

Over the weekend I used Zentropi to build a labeler that blocks requests to use AI to undress or sexualize real people. The labeler itself took maybe 30 minutes to a first solid draft, with another 30 minutes of tweaking. In my testing it's got an F1 of .98 on real examples pulled from X. 🧵 1/6
