OpenTrain AI
Outlier (Scale AI)OpenTrain AI vs Outlier (Scale AI): the short answer
On pay, OpenTrain AI is benchmarked at $6–$50/hr on its own postings (top $60) and Outlier (Scale AI) at Up to $7–$50/hr; ML, EE and quant finance up to $150/hr; their boards do not state enough rates to tell which pays more, so compare against your own hours.
Both are expert networks, so the barrier to start is similar: gated by a screen for a degree, professional expertise, or a skills test.
Both hire for AI Evaluation, Coding, Domain Experts, and Math & STEM; OpenTrain AI also covers Data Annotation, Robotics Data, and Transcription & Audio; Outlier (Scale AI) also covers Writing and Multilingual.
Bottom line: what we know does not separate these two on pay or on how many people they accept, so choose on the specific work each hires for.
