Cambrian Lab Prompt Audit

Turn a fragile production prompt into a measured system.

We audit one real LLM decision flow, score the current prompt, evolve better candidates against labeled examples, and hand back a deployable prompt with measured lift.

Best fit: classification, routing, extraction, moderation, and triage. Not a fit for open-ended creative generation.

Fastest path to first value

Bring 10-500 labeled examples and your current prompt. If you only have 3-5 examples, the app can generate a harder synthetic test set to start the audit.

Offer

One narrow workflow, audited end to end.

Baseline score on your current prompt or agent decision rule
Failure taxonomy showing where it breaks and why
An evolved replacement prompt tested against labeled examples
Before/after accuracy table with confidence interval
Deployment notes: guardrails, output format, and regression tests

What to bring

A prompt that already matters.

This is built for teams that already have an LLM decision in a product, workflow, or internal tool and want it made measurable.

Lead scoring and sales email classification
Support ticket routing and escalation detection
PII, policy, trust and safety, and brand safety gates
Document type extraction and operations triage
Any repeated LLM decision with clear pass/fail labels

Checkout uses the existing Cambrian Lab Stripe setup. The audit pilot can be purchased directly, then we collect the workflow, examples, and constraints by email.

Single evolution

Run the app on one prompt with your examples. Best for immediate validation and a first paid conversion.

Pro subscription

For teams repeatedly improving prompts as data and model behavior drift.
