Liquid-cooled density
Direct liquid cooling allows the platform to sustain a larger power envelope while fitting an eight-accelerator UBB 2.0 system into a deployable rack design.
AMD Instinct accelerator / capacity planning
AMD Instinct MI355X.
The next step in high-memory AMD inference capacity. MI355X brings liquid-cooled density and a larger memory envelope to full-scale, sovereign serving deployments.

Platform profile
Density without a new operating burden.
The hardware advances, while the operating experience stays direct: a platform that turns capacity into isolated compute through the terminal UI, API, and CLI.
A full-scale serving unit
Eight OAM accelerators connect across an AMD Infinity Fabric mesh, creating a coherent, high-memory system for large inference deployments.
An operating platform, not just hardware
ROCm, hardened virtualization, and the automated layers beneath Kubernetes are part of the environment, not a follow-on integration project.
Deployment path
Built to expand deliberately.
Our approach is smaller, well-operated deployments in more data centers, not a single oversized buildout. MI355X capacity fits that plan.
A practical delivery path
Our relationships with AMD, Dell, Broadcom, and Advizex let us plan smaller regional deployments with realistic supply, networking, and service expectations.
A platform that already operates
We are applying three years of automation and operator feedback to MI355X capacity, rather than building a new control plane around a new accelerator.
Experiment complete
The signup form is gone. The signal is not.
We ran an experiment to see whether anyone would put real money behind future MI355X capacity. The response was much stronger than we expected.

our expected response
Our little experiment returned a very loud answer.
That signup form was an experiment. It is over now, and we learned a lot from it. We asked people to pledge $100 toward future MI355X capacity.
We are still raising the capital required to buy and deploy the hardware. Hot Aisle is a three-year-old business with more than $50 million in requests for MI355X capacity and a product built around what developers and businesses actually need.
We are already in active conversations, but the right introduction could make a real difference. If you know someone who should hear our story, put us on a call together. We will make time immediately.
Available now
Need inference compute today?
MI300X capacity is available through the same platform, with isolated VMs and bare metal provisioned without a sales process.
