Three Steps to High-Signal Decisions
Ingest Candidates
Upload model outputs or generated parameter candidates for each prompt/anchor.
Collect Trusted Votes
Run blinded voting sessions with engagement rules and quality filtering enabled.
Act on Evidence
Use rankings, confidence, and lifecycle insights to pick winners and iterate quickly.
Objective Preference at Scale
Single votes are noisy. Trusted aggregate preference becomes signal. HeyBee focuses every paid vote on reducing uncertainty where it matters.
