Sanal Çekirdek

An impressive demo and a dependable system are not the same thing.

The difficulty in generative AI projects is not running a model but making its output trustworthy. Sanal Çekirdek builds the work around guardrails and evaluation sets.

Where answers must rest on knowledge, retrieval sits at the center of the architecture — we cover that on the Enterprise RAG page. This page is about the model itself, its boundaries and its cost.

Use case and model selection

Not every scenario needs the largest model. For summarization, classification and drafting, smaller models are often sufficient and cut cost several times over. Selection happens between measured quality and unit cost.

  • Candidate models are compared on the same test set
  • Latency and cost are criteria alongside quality
  • Data location requirements constrain the choice
  • Model swapping is abstracted so architecture survives it

Guardrails and boundaries

What the model will not do is defined as precisely as what it will. Input and output checks, an allowed topic boundary and a personal data filter are embedded; a request outside the boundary is refused rather than guessed at.

  • The topic boundary is written and testable
  • Personal data is filtered on the input side too
  • Model output never flows straight into a transaction
  • Refusal behavior is tested as well

Evaluation and version management

Whether a prompt change improved or degraded things is knowable only against a fixed evaluation set. Sets are built per use case, and every version is measured on the same one.

  • Evaluation sets are built from your own examples
  • Prompt and model versions are recorded together
  • A regression test runs on every change
  • Human evaluation continues on a sample

Cost and adoption

Cost rises linearly with usage, so caching, prompt length and model tier are managed together. Adoption, meanwhile, depends on users trusting the output rather than on interface polish.

  • Repeated requests are served from cache
  • Simple tasks are routed to a smaller model
  • Spend is tracked per use case
  • User feedback feeds back into the evaluation set

How we work

  1. Define the use case and its acceptance criteria
  2. Compare candidate models on one set
  3. Establish guardrails and boundaries
  4. Measure versions against the evaluation set
  5. Track cost and adoption together

How success is measured

  • Acceptance criteria are met on the evaluation set
  • Out-of-boundary requests are refused consistently
  • Prompt changes produce no regression
  • Unit cost is known per use case

Frequently asked questions

Will our data be used to train the model?

No, unless explicitly agreed otherwise. For enterprise use, retention and training policy is written into the contract, and it is one of the constraints on model selection.

How are hallucinations reduced?

By grounding the model in sources and defining boundary behavior. Returning nothing when no source is found beats returning something wrong, and that behavior is explicitly tested.

Where does this sit relative to Enterprise RAG?

RAG is the architecture that grounds answers in your documents. This page covers model selection, guardrails, evaluation and cost; in most projects the two are built together.

Let's pick one use case, write the acceptance criteria and measure it against an evaluation set — a system rather than a demo.
