Rat Brain–Inspired AI Model Launches on Amazon Web Services

The Biological Computing Company (TBC), a startup that derives computing principles from rat brain cells, has reached a milestone: its technology is now accessible to select Amazon Web Services customers as of Tuesday, with plans to expand to all AWS enterprise clients. The move represents a rare commercial deployment of biological computing, a once-fringe research area that treats living neural tissue as a substrate for computing.

TBC's platform translates neural activity patterns into machine-learning algorithms. Researchers encode visual information into rat brain cells grown on silicon arrays, observe how the neurons respond, and then reverse-engineer those biological processes into software that improves AI models—specifically those designed to generate video.

How It Works#

The startup's approach begins with practical biology. Rat neurons and human stem cells are placed on multi-electrode silicon arrays manufactured by Swiss biotech firm 3Brain. Electrical stimulation patterns travel through the electrodes into the neurons, and the arrays record how the cells respond. TBC's team analyzes the resulting neural activity patterns to identify computational principles that can be extracted into traditional software code.

Cofounder and CEO Alexander Ksendzovsky explains: "We figured out a way to code information, like images for example, to the biological material. We then observe how the biology processes that information, and then we build a tool that mimics that process."

Video generation became TBC's initial target because images map naturally onto the two-dimensional electrode grid, and the field already has well-established performance benchmarks. This allowed the company to demonstrate measurable improvements: its model claims to be up to five times faster at video generation than comparable open-source alternatives while reducing inference costs.

A Crowded Field with Unique Hurdles#

TBC joins other startups exploring biology-based computing. Amazon also partners with Cortical Labs, an Australian firm that combines lab-grown neurons with silicon chips to create "wetware as a service" (WAAS)—including a multi-thousand-dollar biological computer that can sustain neurons for six months.

Biological computing sidesteps some AI efficiency challenges but introduces others. Rather than running purely mathematical algorithms, this approach mirrors how brains naturally process information. Yet the field demands active laboratory work: living cells must be kept viable, continuously monitored, and somehow translated into usable digital signals—a gap that remains technically complex.
