Services

Every modality. One quality bar.

Data labeling

Image, video, text, audio, and 3D annotation with task-specific tooling and calibrated reviewers.

RLHF & model evaluation

Training based on reinforcement through human feedback. A key stage in training modern artificial intelligence models. It helps transform a basic language model (which simply generates text) into a safe and useful assistant that understands human intentions, ethics, and tone.

Data collection & sourcing

Specially curated datasets collected through verified participant networks and data collection programs on open networks.

Audio/Video transcription

Audio and video transcription. We work with a variety of formats and topics to meet your needs

How it runs

A pipeline built for iteration, not a one-off batch.

01
Scope

We map your taxonomy, edge cases, and quality bar before a single label is drawn.

02
Pilot

A small, fast batch validates guidelines and tooling against your ground truth.

03
Scale

Calibrated workforce pods ramp with automated QA and inter-annotator agreement checks.

04
Refine

Weekly accuracy reviews feed back into guidelines as your model's needs evolve.

"Vendor+'s reviewers caught labeling drift our own QA missed for weeks. Our eval accuracy moved more in one sprint than the previous quarter."
