Guy

Guy is a researcher at Security Level 5, an AI Security Tech Lab with the mission to create the technical and strategic optionality for frontier AI labs to reach SL5 (security against priority nation state attacks) for their core internal operations in the coming years. The team developed the world’s first SL5 Standard, and is currently prototyping mock SL5 datacenters in coordination with frontier AI labs. The SL5 work brought together 100+ security engineering specialists across frontier AI labs, the US intelligence community and broader AI Security ecosystem to chart the technical path towards reaching nation-state secure AI Datacenters and frontier AI workflows by 2028.

​

At SL5, Guy is leading the datacenter project, agent security research and various components necessary for SL5. Previously he worked on high-dimensional geometry analysis on language models, algorithmic / graph theory research and low-level engineering for HPC hardware and on low-level / embedded vulnerability research and engineering.

He also worked on a musical about AI which debuted in 2025 titled Out of This Box: The Last Musical (Written by Humans)
