Hi. My name is Charlie Deck. I'm an AI researcher and builder.
My north star is helping land beneficial AI for all: moving frontier capability from impressive demonstrations into dependable systems people can understand, use, and build on.
I believe a post-scarcity future is possible, but only if we stay close to the human shape of it: curious, challenged, collegial lives coexisting with superintelligence.
I'm in NYC. Reach out if you have ideas, projects, or provocations worth exploring together.
Work. Since Q4 2024, I've been at Reflection, where I helped lead early product explorations, build evaluation and tooling systems, and support work on delivering safe frontier AI in practice, including frontier open-weight models accessible to all.
(If you're interested in joining our mission of SOTA open-weight AI for all, please check out our open roles.)
Previously, I was on Google DeepMind's AI experience team, where I explored product concepts and built research-facing tools for generative AI.
My superpower is bringing research, product, and execution together around systems that need to work in practice. A recurring part of the work is building the feedback loops that help a lab distinguish real capability from a merely persuasive demo.
Past work. Before AI labs, I independently built products across mobile, web, and desktop platforms that reached millions of users.
Working end to end on creative tools, games, and experiments taught me to care about taste, interfaces, launch constraints, and the gap between a promising prototype and something people actually return to.
That background still shapes how I approach frontier systems now: not just whether they can do something once, but whether they become coherent, usable, and worth relying on in the world.
