How it works
From training goal to production data in three steps
Scope with our experts
We turn your training goal into calibrated guidelines and a pilot batch — live within days, not weeks.
Matched, vetted annotators
Domain-matched contributors who pass qualification tests on your exact task before touching production data.
Watch quality in real time
A client portal with live progress, throughput, and reviewable samples — no black box, no weekly email attachments.
What we deliver
Data services across the training stack
RLHF preference data
Pairwise comparisons and rankings with written rationales, from annotators calibrated on your policy — the signal your reward model actually needs.
Model evaluations
Rubric-scored assessments of accuracy, helpfulness, and safety across single responses and full conversations, on an absolute scale you define with us.
Custom annotation
Classification, span labeling, and bespoke pipelines for the data problems that don't fit a template. Scoped fast, delivered with a full audit trail.
Why Orion
A platform, not a spreadsheet pipeline
Most data vendors hand you a weekly CSV and ask for trust. Orion gives every client a live portal and every annotator a purpose-built workspace — so quality is visible, not promised.
- Vetted, domain-matched annotators — qualification-tested on your task
- Live progress, throughput, and reviewable samples in your portal
- Calibrated rubrics and layered QA on every batch
