Krzysztof Gwiazda is a Polish individual pursuing entry into AI safety research, specifically mechanistic interpretability. In Q3 2024, he received a $5,000 grant from the Long-Term Future Fund to support a two-month period of upskilling in mechanistic interpretability, with the aim of completing two to three projects in the field before exploring adjacent areas. His background appears to be in software and computer science. He represents an early-career pathway into technical AI safety research through self-directed study supported by EA-aligned funding.

Gideon Futerman is a researcher focused on AI safety and existential risk, currently working as a Special Projects Associate at the Center for AI Safety (CAIS) and as a MATS (ML Alignment Theory Scholars) scholar on gradual disempowerment research. He studied Earth Sciences at St Edmund Hall, University of Oxford, where his academic interests first led him into existential risk research through the lens of solar radiation modification (SRM) and climate change. He has been affiliated with the Centre for the Study of Existential Risk (CSER) at Cambridge, contributing to work on how SRM interacts with global catastrophic risk scenarios. His AI safety research spans governance and policy approaches to advanced AI, including analysis of pathways to slowing AI development, international coordination to avoid an artificial superintelligence race, and the systemic risks of gradual human disempowerment as AI capabilities increase. He writes on these topics at his Substack and has published at AI Frontiers, The Oxford Scientist, and co-authored an SSRN paper on escalation pathways in the age of solar geoengineering.

Nicky Case is an independent Canadian creator specializing in interactive explorable explanations and educational games. Born in Singapore and raised in Canada, they dropped out of UBC's Computer Science program and worked briefly as a software engineer at Electronic Arts before becoming a full-time independent creator funded through Patreon. They are best known for projects such as "Parable of the Polygons" (a simulation on systemic bias), "The Evolution of Trust" (an interactive game theory explainer), and "Adventures with Anxiety," all of which aim to help people understand complex systems through play. In the AI safety space, they received a Long-Term Future Fund grant for a one-year stipend to create accessible explainers on AI alignment, which resulted in the "AI Safety for Fleshy Humans" series hosted at aisafety.dance, developed in collaboration with Hack Club. In early 2025 they also participated in the MATS AI Safety Research Bootcamp in London.
