Cyrus Nikolaidis

I build safety systems for AI, spanning evaluations, guardrails, and scalable monitoring for deployed models and products.

At Meta Superintelligence Labs, I lead work on safety evaluations and oversight for deployed products and models. Before moving to MSL, I led and contributed to team efforts behind several open-source safety projects at Meta, including CyberSecEval, LlamaFirewall, Prompt Guard, and Llama Guard.

Earlier at Meta, I incubated applications of machine learning to privacy and security problems. Before that, I worked on recommendation systems, building the first version of Instagram's feed recommendations ranking and working on Facebook Search.
