The Biological Computing Co. claims 5x faster, 80% cheaper AI video

TBC, originally called Biological Black Box, was founded by neurosurgeons Alex Ksendzovsky and Jon Pomeraniec and raised $25 million in February 2026. The company grows cortical nerve cells on chips with 4,096 electrodes and measures how activity spreads and fades to derive software adapters. In an experiment with the open Minecraft world model Oasis, an adapter with about 156,000 parameters scored about 19 percent better than the original on differential entropy across ten test videos. An outside test by Bluesky Compute in July found about 4.4 times lower inference costs and more than three times as much coherent video as the base model. For the commercial model, however, TBC has not published a controlled comparison or named the base model, hardware, resolution, clip length, or quality metric, so whether its biological approach outperforms purely digital methods remains an open question.
