Chip running Un-0 reportedly uses less than 900 nanojoules to generate an image

In a September 16, 2026 update, an Un-0 team member said hardware had arrived that summer and was running the model released in June. They said the shared images came from actual hardware, claiming energy use below 900 nanojoules per image—many orders of magnitude less than conventional machines. The author also credited AI with tighter research loops, saying the project went from no team in January to tape-out, the design handoff for fabrication, in five months. In a follow-up, they described a sequence generated on the chip and said the system had been taught to count.
