The honest brief

Labelbox

Combines an enterprise labeling UI, model-assisted pre-labeling, and an on-demand expert-labeler network in one usage-metered platform.

  • Mature, full-featured labeling UI
  • Catalog curation + Model Foundry evals
  • Spans RLHF, robotics, and eval datasets
  • Usage-based LBU pricing hard to forecast
  • Enterprise focus, steeper for small teams
  • Proprietary platform, no self-host

T-Rex Label

Visual-prompt zero-shot detection auto-labels every matching object across a dataset from one example box—no per-class training like traditional annotators.

  • No per-class training needed
  • Handles dense and occluded scenes
  • Varied-lighting robustness
  • COCO and YOLO export
  • Integrates with Roboflow, Labelbox
  • Browser-only, no offline mode
  • Pricing not clearly published
  • Detection-focused (boxes and masks)
