Our quest to build a scalable, LLM-safe design system
Project Glasswing: what Mythos showed us
In recent weeks, we pointed Mythos and other security-focused LLMs at live code across critical parts of our infrastructure. We share what we observed, the models’ strengths and weaknesses, and what the work around them needs to look like before any of it can scale.

Open by Design: ROOST's Approach to Safety Tool Development

Developer Ecosystems for Software Safety
How to design and implement information systems so they are safe and secure is a complex topic. Both high-level design principles and implementation guidance for software safety and security are well established and broadly accepted. For example, Jerome Saltzer and Michael Schroeder’s seminal overview of principles of secure design was published almost 50 years ago,10 and various community and governmental bodies have published comprehensive best practices about how to avoid common software weaknesses—for example, Common Weakness Enumeration (CWE)a and Open Worldwide Application Security Project (OWASP) Cheat Sheet Series.b

The rebel alliance
This blog is co-authored with Zoe Weinberg and Matt Hawes at ex/ante, and is a follow-up to our first blog post on the topic, 'You don't own your memory.' We need an open architecture that puts us in control of our memories while making their exploitation technically impossible. But how will this shift happen? In order to discover possible implementations, we must understand how our data informs LLMs. The three predominant context engineering techniques are prompt design, retrieval-augmented ...

3M LifeLab SXSW | SOFTlab | Archinect
We worked with 3M and BBDO to create the 3M LifeLab at SXSW. The structure was not simply a space that showcased 3M products, but was created using some of the amazing materials created by 3M. We designed a multi-functional structure that acted as a ceiling, spatial divider...

Sensitive data + tool use + LLMs + app-centric security model = danger. LLMs turn any text into potentially executable instructions, exploding the attack surface of traditional security models.
