Frontier AI has outgrown the lab. The decisive questions now are about power — who builds the models, who controls them, and who gets to build on top of them. AI Frontiers is for the people doing the building: founders and operators creating products, companies, and strategy at the edge of what AI can do — on infrastructure owned by a handful of labs and governed from a handful of capitals. Each season charts where that frontier has moved, from the labs shipping the models to the capitals writing the rules, and what it means for anyone building something that lasts on ground that keeps shifting. Hosted by Fabio Lauria, founder of ELECTE. No hype, no jargon — strategy, stakes, and a builder's-eye view of the most consequential infrastructure of the century.
