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.

in case you missed it, gpt-oss-safeguard also came with a technical report that goes into the details of
- limitations
- multilingual performance
- a new, more complex benchmark dataset of multi-turn conversation-style data

Thank you to Fidji Simo for addressing the audience via video yesterday ahead of our panel at the Paris Peace Forum. The conversation on how AI systems can help create a safer internet for the public good through open source tooling is only just beginning.

At the Paris Peace Forum earlier today, we announced the release of gpt-oss-safeguard in partnership with OpenAI. Now, we’re announcing the launch of the ROOST Model Community (RMC).

There's tried and true ways for how OSS applies to software, but that doesn't fit squarely with the realities of AI development.

That's why I'm grateful OpenAI is trying something new with @roost.tools, openly releasing weights with a commitment to work with the ROOST Model Community to iterate

ROOST.tools has been building against the DIRE framework for online trust and safety: Detection, Investigation, Review and Enforcement. ROOST's Coop and Osprey tools address I, R, and E, but Detection is best addressed by classification models.

Enter gpt-oss-safeguard from OpenAI
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.

i'm also rly proud of writing up the User Guide for this T&S reasoning model: cookbook.openai.com/articles/gpt...

It includes how this could work with @roost.tools first public tool, Osprey!

I spent the past 2 days at the INHOPE Summit in DC, an event that brings together global hotlines that fight against Child Sexual Abuse Material (CSAM) online. @roost.tools aims to provide open source tools for platforms/orgs to more easily detect and report child sexual abuse. (1/n)

there's some more to do here in the repo to get it where i want, but will probably write a leaflet soon on making moderation work for people that are not Bluesky PBC. hoping that this will be a good step in that direction.
