Expert human intelligence
for AI that performs.

Your model is only as good as the humans who trained it. We staff the specialists who train, judge, and red-team frontier AI — across RLHF, safety, multimodal eval, and 50+ languages.

Why specialization matters

The next generation of AI demands
a different kind of human expertise.

As AI models mature and move into healthcare, legal, finance, security, and enterprise operations, the quality of human input becomes the defining variable. More data is no longer enough. The right expertise — deeply embedded in your program — is what separates models that perform from models that fail in production.

Expert-in-the-Loop (EITL)
Beyond human-in-the-loop.

General annotators produce general quality. Credentialed domain experts produce production-grade AI. Every engagement is built around the right specialist — Architects who set the standard, Judges who enforce it, Adversaries who stress-test it — matched to the depth your model actually needs.

Credentialed ExpertsDomain JudgesNamed Specialists
Domain Specialization
Every domain needs its own expert.

A clinical reviewer evaluating clinical RLHF pairs catches failure modes a general annotator never sees. A legal specialist red-teaming a legal AI finds liability traps that prompt engineers miss. A trained safety reviewer identifies dangerous knowledge refusals that only a domain specialist recognizes. The credential is not a credential — it is the capability itself.

Sovereign Delivery
Your data stays in your environment.

For frontier AI labs, regulated enterprises, and government programs, the training data, model outputs, and proprietary prompts used in evaluation are among the most sensitive IP a company holds. We build every engagement with data sovereignty as the foundation — on-premise deployment, secure facilities, air-gapped options, and zero third-party data access. Not an exception. The default. Built for programs where data residency is non-negotiable.

On-Premise DeliverySecure FacilitiesData SovereigntyAir-Gapped Ready
Embedded Collaboration
Inside your team, not at arm's length.

The most effective RLHF, evaluation, and annotation programs are not vendor-to-client. They are team-to-team. Our specialists embed directly into your workflows, tools, and quality framework — building the institutional knowledge that makes feedback more consistent and more valuable over time. A standing capability, not a periodic deliverable.

Technical Capabilities

Eight capabilities where
credentialed judgment moves model quality.

Every engagement is staffed from one or more of the practices below. Each is led by specialists matched to the credential and depth the task requires.

Domain RLHF
Preference ranking by credentialed domain experts.

Your reward signal is only as good as the ranker. Our judges are domain specialists — clinical reviewers, licensed attorneys, senior engineers, and trained safety evaluators — ranking preferences inside their own domain of practice. A reward model that actually reflects expert judgment.

Preference RankingDomain Reward ModelingDPOExpert Calibration
Expert SFT / CoT
Reasoning chains authored by the specialist your model is learning from.

A physician-authored clinical CoT teaches the model physician-style reasoning. A mathematician-authored proof teaches proof-style reasoning. Not crowd-sourced step-by-step — expert-authored.

Reasoning ChainsInstruction TuningExpert DemonstrationsCoT Quality
Red Teaming & Safety
Adversarial testing embedded inside your safety program — before users find the failure modes.

Jailbreak discovery, bias detection, harmful-output surfacing, and policy-compliance review — delivered by specialists who work inside your trust & safety workflows. Every finding includes reproduction steps and a recommended mitigation.

Jailbreak TestingAdversarial PromptsTrust & Safety ReviewReproduction Steps
Factuality & Grounding Audit
RAG verification by specialists who read both the source and the inference.

Every claim traced to a source document. Every citation verified. Every hallucination logged with reproduction steps. Built for products where a wrong answer is a liability, not a nuisance.

RAG GroundingCitation VerificationHallucination ForensicsSource Tracing
AI Risk & Compliance Evaluation
Regulatory-grade model assessment for enterprise procurement gates.

Model risk review, bias audits, and compliance documentation that survives enterprise procurement and regulatory inquiry. Built for AI products entering regulated markets — financial services, healthcare, government.

Knowledge Graph & Ontology
Domain graph architecture for AI products that need meaning, not just tokens.

Entity models, taxonomies, and relationship schemas designed by ontologists. For vertical AI, enterprise search, and RAG systems where context and relationship matter more than surface text.

Ontology DesignEntity ResolutionTaxonomy EngineeringVertical AI Schemas
Agentic Evaluation
Multi-step reasoning, tool use, and end-to-end workflow quality.

Planning trajectories, tool-call correctness, sub-task decomposition, workflow completion — evaluated step-by-step, not just on final output. For AI agents that act on the world.

Long-Context & Memory Evaluation
The quality frontier for 2026 — the one most labs don't yet measure.

Coherence across 100K+ token contexts. Memory recall in multi-turn sessions. Context-drift in long-running agents. The capability benchmarks don't yet capture — but your users notice.

How we deliver

Named PODs. Credentialed specialists.
Built for continuity.

No rotating crowd workers. No ticket-defined scope. No surprise handoffs. Every Quantryx program is built on a defined POD shape (sized by phase) and staffed from a defined role framework (tiered by depth).

POD Structure — three shapes, sized by phase
01 — Calibration POD
4-6 specialists · Architects + Judges

Phase one of every program. Builds the evaluation rubric, gold dataset, calibration set, and kappa baseline with your team. The foundation the ongoing program runs on top of.

02 — Production POD
5-12 specialists · Judges + Adversaries + PM

Steady-state operations. RLHF, red-teaming, factuality audit, content ops, drift monitoring. Includes embedded program management, QA, and calibration. Scales with your program.

03 — Advisory POD
1-2 specialists · Senior Architects

Embedded strategic capacity for AI governance, eval framework design, regulatory readiness, and RFP response. Retainer model with direct access to domain leadership.

Cognitive Role Framework — three specialist types, tiered by depth & credential
Tier 1 — Expert
Architects

Build the ground truth. Design evaluation rubrics, author SFT/CoT training data, establish the gold standard. High-stakes, high-judgment work.
