Human-validated training data and evaluation services for frontier AI models
Chain-of-thought reasoning traces, SME-level RLHF, supervised fine-tuning demonstrations and adversarial red teaming for the most capable models.
Golden trajectories, RL environment design, failure-mode taxonomies and software-engineering-driven deep evaluation for autonomous agents.
Multilingual ASR and conversational speech data, expressive TTS annotation, vision-language model training data, video action labelling and voice-agent evaluation.
LiDAR point-cloud labeling, multi-camera sensor fusion, robot demonstration trajectories, world-model rollouts and embodied interaction logs.
The all-in-one computer vision platform for labeling, training and deploying vision AI
Speed up data prep with auto-annotation, model-assisted labeling, pixel-precise segmentation tools and consensus/approval workflows for consistent quality across annotators.
Build training workflows in a drag-and-drop interface, tune architecture, batch size and epochs, and visually evaluate model performance against ground truth.
Train classification, object detection, keypoint and segmentation models to cover tagging, tracking, pose estimation and pixel-level analysis use cases.
Ship models to edge or cloud environments via hosted APIs, with monitoring, scaling and secure authentication for production inference.
SpecialistConnects teams directly with verified human participants for preference tuning and studies, but lacks managed end-to-end labeling pipelines.
