On-Prem Customized LLM for Mortgage
Guardrails, retrieval and prompts are engineered against your documents and policy language, then deployed to run on your infrastructure. Borrower data stays within your boundary, and a named person approves its output before it is used.
Why inside your walls
Nowhere new. The model runs inside your environment, against your sources, under your access controls — so nonpublic personal information never leaves the boundary your examiner already reviews.
Only what your policy language allows, drawn from sources you approved. Guardrails are engineered against your rules, not a generic assistant's defaults.
A named person. The model drafts, summarizes and answers; a person approves anything that reaches a borrower or a decision — and the record shows who.
What "customized" means
The customization is the engineering — and it is the part you are actually buying. It happens at build time, against your material.
Retrieval
Policy manuals, procedures, product guides and the agency guides you work to — indexed as approved, versioned sources, so an answer can always be traced to the passage it came from.
Guardrails
Permitted topics, required disclosures, refusals and handoffs written from your own policies — so the boundaries are the ones your compliance team already signed.
Prompts and workflow
Built for a specific role and workflow — what a reviewer needs from a summary, what a servicing agent needs from an answer — rather than a general-purpose conversation.
Integration
Read access to the systems the workflow needs, scoped by role, with every call logged. Integration and data boundaries are defined before deployment, not discovered after it.
Where it earns its place
A language model earns its place where people spend time reading, finding and drafting — and stays out of the paths where a decision is made.
Where it helps
Where it never goes
How it is contained
One use case, one set of approved sources, one set of permitted actions — not open-ended access to everything.
A named person approves output before it reaches a borrower or a record.
Inputs, sources retrieved, outputs and approvals logged — evidence a regulator can hold.
LLM Assurance is built in: a versioned suite, agreed thresholds and a re-run on every change.
An inventory entry, risk tiering and monitoring for your FRAME-aligned governance file.
Runs on your infrastructure, under your access controls and your security team's review.
How it is delivered
One use case at a time, with assurance as a stage of the build — not a review at the end.
Scope
Agree the use case, the sources it may use, what it must never do, and who approves its output.
Engineer
Guardrails, retrieval and prompts built against your own documents and policy language.
Assure
LLM Assurance runs the specification as a suite, with thresholds agreed before release.
Deploy
Deployed into your environment to run there, with logging and a human control point.
Monitor
Agreed signals watched; every model, prompt or source change re-tested before it goes live.
The delivered client code, configuration and documentation are yours. The Reslt Platform that builds and tests them stays with us. Model licensing and any third-party terms are defined for your environment before deployment.
Infrastructure suited to the model, access to the approved sources, and a named owner for the use case. Runtime dependencies, access and operational responsibilities are agreed before anything is deployed.
Questions buyers ask
A mortgage language model whose guardrails, retrieval and prompts are engineered against your own documents and policy language, then deployed to run inside your environment. It proposes; a named person approves its output before it is used.
No. The model runs on your infrastructure, against approved sources, under your access controls.
No. No model sets a rate, makes an eligibility or credit decision, or writes a disclosure on its own. Those paths remain deterministic, reviewable code.
LLM Assurance is built in — a versioned suite with agreed thresholds, re-run on every model, prompt or source change — and each deployment is recorded in your AI inventory with risk tiering and monitoring for your FRAME-aligned governance file.
You own the delivered client code, configuration and documentation. The Reslt Platform that builds and tests it stays with Reslt AI. Model licensing and third-party terms are defined for your environment before deployment.
Where to start
We will scope the sources, the guardrails and the control point with you, and show how it would run inside your environment.
