What Patronus AI does
Patronus AI provides experiments, tracing, production monitoring, dataset generation, human annotation, red teaming, and evaluator models for LLM applications.
Patronus focuses on measuring and improving generative AI rather than serving end-user answers. Its platform covers experiments, production monitoring, visual analysis, dataset generation, prompt management, human annotation, guardrails, red teaming, and evaluator models for factuality, safety, and custom criteria. Self-hosting documentation indicates private enterprise deployment is possible.
Patronus does not present a universal public self-service rate card, so pricing should be treated as custom. Request line items for evaluator calls, trace volume, retention, seats, models, red-team generation, datasets, support, regions, and self-hosted infrastructure. Application inference, human annotation, remediation, and any third-party judge usage may be separate.
An evaluator can disagree with qualified reviewers or reward superficial patterns. Red-team generators do not exhaust the attack surface, and production traces can contain regulated or confidential content. Start with a human-coded benchmark, measure error by task and subgroup, minimize logged data, restrict access, test self-hosted responsibilities, and make score thresholds advisory until they show stable relationship to real failures.
How Patronus AI works
A team sends application inputs, retrieved context, outputs, traces, or datasets through the Patronus platform, API, or SDK. It applies selected proprietary, rubric-based, custom, or third-party evaluators, runs experiments and red-team generation, and aggregates scores, failures, alerts, and comparisons. Tracing can monitor production interactions and datasets can preserve discovered cases. Engineers and subject-matter reviewers confirm errors and choose changes to prompts, retrieval, models, tools, or policy.
How to set up Patronus AI
Define the quality taxonomy
List user tasks, safety and factual risks, severity, evidence requirements, slices, acceptable abstention, owners, and the decisions scores may trigger.
Confirm architecture and terms
Choose hosted or self-hosted use, document providers, regions, retention, encryption, identity, deletion, model training terms, support, and complete cost.
Connect a sandboxed application
Instrument representative traces with least-privilege keys, synthetic or minimized data, version metadata, and disabled consequential tools.
Calibrate evaluators
Compare proprietary, custom, deterministic, and human scores on a stratified benchmark; measure disagreement, variance, latency, and cost.
Operate monitored release gates
Run experiments and red teams before release, sample production, investigate evidence behind alerts, route uncertain cases to experts, and preserve rollback.
Patronus AI FAQs
What does Patronus AI evaluate?
It supports generative application experiments, traces, RAG and agent behavior, safety and factuality criteria, custom evaluators, and production monitoring.
How much does Patronus AI cost?
Public materials do not establish a universal rate card. Obtain a current quote for the selected models, usage, deployment, retention, and support.
Can Patronus be self-hosted?
Official documentation describes self-hosting prerequisites for eligible deployments; confirm the commercial package and operational responsibilities.
Does an evaluator stop hallucinations?
No. It may detect some unsupported output. Retrieval design, constraints, verification, human review, and safe fallback are still required.
Can scores automatically approve a release?
They can inform a gate, but critical releases need calibrated thresholds, reviewed exceptions, slice analysis, and an accountable human decision.
