Scale AI

Powers AI training data for OpenAI, Meta, and US government defense programs
Nucleus data management platform finds dataset edge cases intelligently
Human-in-the-loop quality validation ensures highest accuracy benchmarks
Supports LIDAR, radar, video, text, and satellite imagery labeling at scale
Rapid API enables programmatic data collection and labeling orchestration
Pricing not transparent - enterprise contracts only for most services
Not accessible for small teams needing occasional labeling work

Weights & Biases

Experiment tracking logs every model run with metrics, hyperparameters, and artifacts
Sweeps automates hyperparameter search across dozens of configurations in parallel
Artifacts versioning tracks every dataset, model, and evaluation checkpoint
Used by DeepMind, OpenAI, and NVIDIA as the standard experiment tracking tool
Reports create shareable visual summaries of model training progress
Free tier has storage limits for large model artifact repositories
Can feel heavyweight for small projects not requiring systematic experiment tracking
