Private AI Hosting
Your models and your data stay on hardware you control. MCG Labs builds and operates private AI hosting: on-prem and private-cloud LLM inference that never calls out to a public API, with model choice, per-seat access control, and a full audit trail of every request.
How Private AI Hosting Works
Six things have to be true before an engineering team will trust a model with its real data. We build to all six by default, not as an upsell.
Data Never Leaves Your Boundary
Every prompt, response, and embedding stays inside the network perimeter you define. We do not route your requests through a public API and we do not send your data to a third party to get an answer. Whether the boundary is a single rack in your server room or a private VPC you control, the model runs there, and nowhere else.
On-Prem and Private-Cloud Inference
We deploy inference on hardware you own or on private cloud capacity you control, sized to the workload rather than to a vendor's pricing tier. The same engineering discipline that goes into a production board goes into the inference stack: measured, monitored, and built to run unattended.
Model Choice and Versioning
There is no lock-in to one vendor's model. We stand up the open-weight models you choose, track which version served which request, and move a model forward or back on purpose, instead of absorbing a provider's silent change on the other side of an API call.
One Endpoint, Many Seats
A single gateway fronts the fleet of models you run. Every engineer, tool, or internal service gets its own key and its own identity, routed through that one endpoint, so adding a seat is a provisioning decision, not a new integration.
Auditable Access
Every call is logged against the identity that made it: who asked, which model answered, and when. That log is yours to query. It is not a dashboard we hold the keys to, which matters the day someone asks exactly what the model saw.
Who It Is For
Regulated teams, IP-sensitive engineering groups, and any environment where sending a prompt to a public API is a compliance problem before it is a technical one. If your data cannot leave the building, your inference should not either.
One Gateway, Your Whole Fleet
Private hosting is not just a model running on a server. It is a gateway that fronts the fleet: one endpoint, per-seat keys, identity-controlled routing, and an access log underneath all of it. The same pattern scales from one model serving one team to several models serving many teams, without every new seat becoming a new integration to maintain.
If your data cannot leave the building, your inference should not either.
Private hosting pairs naturally with augmented engineering work, where the engineer directing the model and the model itself sit behind the same private endpoint, and with a full-stack product build that embeds private inference directly into the hardware we deliver.
Private AI Hosting FAQ
What is private AI hosting?
Private AI hosting means your models run on hardware you control, on-prem or in a private cloud, instead of calling a public API. Prompts, responses, and embeddings stay inside the boundary you define, and access to the models is routed through a single gateway with per-seat keys and a full audit trail.
Is self-hosted LLM inference secure?
Self-hosted LLM inference removes the biggest exposure of a public API: your data never has to leave your network to get an answer. Security still depends on how the deployment itself is built. Identity-controlled access, per-seat keys, and a logged, auditable trail of every request are how we build every private AI hosting deployment, not optional extras.
Can we choose and version our own models?
Yes. Private AI hosting with MCG Labs is not tied to one vendor's model. You choose the open-weight models you run, and we track which version served which request, so you can roll a model forward or back deliberately instead of absorbing a provider's silent change.
