Cashcrown // ai quality evaluation · 09/11
An evaluation harness for LLM/RAG systems: a golden set, automated metrics, an LLM-as-judge calibrated against human labels, and a regression gate that blocks a deploy when quality drops.

Without evaluation you do not know whether a new prompt, model, or RAG change improved quality or quietly broke it. Eyeballing answers does not scale and does not catch regressions before they reach the customer.
We assemble this product from measured models and components - see the full live pipeline:
We deploy Eval Harness to end eyeball evaluation: we build a versioned golden dataset, automated faithfulness metrics, and a hard CI/CD gate blocking regressions.

We work in ranges that depend on scope: we start with a fixed-cost pilot in which we build the golden set and the first regression gate. An eval usually pays off at the first regression it catches before it reaches the customer: it saves hours of manual review and costly slips. Calculate the return in the ROI calculator.
Yes. We run the harness in your CI as a gate before deploy: a red result blocks the release. It runs self-hosted with zero retention: test data and embeddings (BGE-M3) stay with you, we mask PII before the cloud and handle sensitive paths locally: GDPR and AI Act compliance designed in from the start.
We start with a few dozen representative cases and their manual labels: that is the golden set we calibrate the LLM-as-judge against. An eval supplements but never replaces human judgement on high-stakes outputs: the automation catches regressions and tracks the trend, while a human makes the critical calls and has the final say at the gate.
