DATA ANNOTATION & RLHF

Precision Labeling · Engineering-Aligned · Production-Grade

Most annotation platforms sell volume. We sell model performance. If your data isn’t mapped to your engineering goals, your model fails regardless of the architecture. We integrate domain experts directly into your training pipeline to ensure the feedback fed into your model is as precise as the code you write.

THE REALITY OF ANNOTATION

If Your Annotators Don’t Understand Engineering Goals, They Can’t Label for Them

Standard crowd-sourced labeling fails when applied to complex, domain-specific AI models. We eliminate the systemic breakdown points in traditional annotation pipelines.

!
EXPERT GAP

Context Blindness

Crowd-sourced workers lack the deep technical, legal, domain or medical expertise your specific AI training data demands.

!
SILOED PIPELINE

The Handoff Disconnect

Data delivered as a static CSV/JSON file without any visibility into post-training model behavior or loss metrics.

!
INCONSISTENCY

Noisy Signals

Vague guidelines and inconsistent annotators create contradictory data, leading to unpredictable model performance.

!
RISK EXPOSURE

Safety as an Afterthought

Red-teaming requires systematic engineering rigor and adversarial probing, not just checking boxes off a static list.

OUR APPROACH

High-Precision Feedback Loops for Superior Model Outputs

We structure data curation and human feedback into a continuous, engineering-aligned cycle designed to maximize downstream model evaluation metrics.

Preference Modeling

RLHF & Preference Data

We structure human feedback (pairwise ranking, comparison, and multi-turn preference scoring) to explicitly align model behavior with your specific domain and business requirements.

THE ALPHAESAI COMMITMENT

We Define Quality by Model Performance, Not Label Count

We don't measure progress by raw output counts. Our sole benchmark is how well your AI model performs when deployed to real-world users.

Contextual Alignment

We tune label schemas to what your specific model architecture and loss functions need to learn.

Direct Feedback Loops

We tie data annotations directly to post-training evaluation metrics and fine-tuning results.

Expert Matching

We don't use generalist crowd pools. We match domain practitioners to your exact industry taxonomy.

Outcome Accountability

We measure success by how your model performs in production, not by how many raw labels we click.

SPECIALIZED DOMAIN NETWORKS

Vetted Experts Matched to Your Industry Taxonomy

We match specialized annotators to the exact nuances of your industry data.

Healthcare & Life Sciences

HIGH COMPLEXITY

Radiology report annotation, EHR structured extraction, clinical coding (ICD-10/SNOMED), medical QA.

Finance & Fintech

STRICT ACCURACY

Transaction classification, earnings call sentiment, SEC filing parsing, fraud pattern tagging.

Legal & Compliance

DOMAIN-SPECIFIC

Claims risk extraction, policy document classification, property damage vision analysis.

FREQUENTLY ASKED QUESTIONS

Data Curation & RLHF Inquiries

Crowd platforms prioritize raw volume and speed using unvetted gig workers. We prioritize expert judgment, strict quality control, and engineering alignment. Our annotators are domain specialists (MDs, attorneys, financial analysts, software engineers) who understand what your model is trying to achieve.
