Private AI, or on-premise LLM deployment, means the language model runs on hardware you control instead of a provider's cloud. When your team pastes a contract, a patient note or a GST working into a hosted chatbot, that text travels to someone else's servers. For a lot of work that is fine. For some of it, a board, an auditor or a client will ask where the data went, and "a US provider's API" is not the answer they want.
Private AI deployment removes the question. We take an open-weight model, meaning a model whose trained weights are published for anyone to download and run, and install it on a server in your office, your data centre or a cloud region you pick. Your staff use it through a web chat, an API or the tools they already work in. Nothing is sent to OpenAI, Anthropic, Google or anyone else unless you decide it should be.
The server answers questions, drafts documents, summarises files, extracts fields from PDFs and runs agents, all against your own data. You pay for the hardware or the rented GPU, not per token, so heavy internal use does not grow the bill. You also own the uptime, which is why sizing, monitoring and a clear runbook are part of every deployment we do.
This is one of the main things our engineers in Chennai build, and it is where most of our lab work on local models goes.
