Most tooling for fighting fraud and abuse was built for 2010s social media. The abuse evolved. The tools mostly didn't. @julietshen.online at Marketplace Risk NYC on why open source and open weight models help: you run them yourself, so sensitive data never leaves your systems. github.com/roostorg

Another day at the Crimes Against Children Conference. Time well spent with folks from Cinder and Thorn, and demoing Coop, the world's first free, open source review and enforcement system any org can self-host, with NCMEC reporting built in. Nobody solves this alone. #CACC2026

That's a wrap on TrustCon 🐓 3 days, 6 sessions, 1 launch (Osprey 1.1.0!), many chicken hats. Favorite moment: non-engineers building working moderation rules in our workshop — safety tooling you can study, modify, and use. One year of Coop & Osprey. Just getting started.

Final day of #TrustCon. We saved the hands-on stuff for last. 1 PM: ship your own T&S tooling with Coop + Osprey (incl. today's 1.1.0). No-code path or run it locally. Your practice labels land on real posts right here on @bsky.app. 3 PM: AI Can't Touch This: Where AI actually helps T&S Say hi!

TrustCon day 2 💚 Thank you to everyone who packed yesterday's panel on what open source means for your T&S stack with @julietshen.bsky.social. Fitting week: 1 yr ago today we introduced Coop & Osprey. Today they help protect 360M+ users, including 45M events/day right here on Bluesky. roost.tools

We celebrated last night by convening fellow allies in Geneva for a conversation on building AI safety in the open and heard from builders wanting better safeguards for kids-focused products, from funders architecting public interest infrastructure, and from researchers working on AI accountability.
Thank you to Yoshua Bengio, Dr. Joy Buolamwini, Tristan Harris, Maria Ressa, Megan J Smith, Ayah Bdeir, Marija Manojlovic, Andrew Sliwinski, Amanda Craig Deckard, Mark Schaan, Martin Tisné, Ryan Mcmaster, Hon.William Kabogo Gitau, E.G.H., and Benjamin Prud'homme for the great remarks, insights and partnership.

On the integration side, Coop now supports OpenAI's omni-moderation-latest model as an image moderation signal source. HMA (hasher-matcher-actioner) exchanges can now be configured directly from the Coop UI, removing the need to manage that setup separately. You still need your own NCMEC creds!
A screenshot of Coop's UI showing the page for creating hash banks. The backend is HMA, hasher-matcher-actioner, and the UI allows you to configure a third-party signal exchange like NCMEC. You still need your own credentials, but Coop makes it easy to select what environment and ESPs you want to get hashes from

A lot of the settings were only available in the database, so we moved them into a new Settings page: - Organization settings - Enabling and managing Appeals - Wellness settings - Review settings (like requiring a policy for every action or enabling skip for mods) - Configuring partial items

We had multiple platforms adopt Coop during the 1.0 development cycle, which gave us critical real-world feedback. Several significant capabilities shipped as a result: User Strikes are now enabled, giving platforms a native way to configure, track, and act on repeat violations directly within Coop
a screenshot of Coop's interface showing a page configuring user strikes. There are 4 tabs: policy scores where you weight policies, strike enabled actions to select what actions can be triggered by strikes, thresholds and settings to set the threshold for a strike and how long the TTL for counting strikes is, and analytics

Last week, something powerful happened. People from all around the trust and safety community came together. We hosted the Open Safeguard Hackathon in San Francisco with @hf.co and OpenAI —and it was a reminder of what’s possible when we build safety openly and together.
Group photo of participants at the Open Safeguard Hackathon hosted by ROOST,  Hugging Face, and OpenAI on Dec. 8, 2025, in San Francisco. The hackathon brought together practitioners from industry, academia, nonprofits, and policy who all rolled up their sleeves to test open safety models, pressure-test policies, and prototype real-world solutions, from multilingual safeguards to appeals copilots and red-teaming against jailbreaks.

During our @parispeaceforum.bsky.social panel last week, Dr. Giada Pistilli eloquently explained that transparency in AI isn’t just a technical challenge — it’s a societal one. The more people who can see, shape, and question these systems, the more accountable and representative they become.

Excited to announce here at the @parispeaceforum.bsky.social that, after months of joint technical work together, OpenAI will open source through ROOST one of its main internal models that handles detection and moderation. This will allow anyone or any company to use, test, and study the model.
