## Overview

Outlier AI is a work platform built around the idea that human expertise is still the fastest way to make AI models better. Professionals in fields such as software engineering, mathematics, physics, medicine and dozens of languages sign up, verify their skills, and are matched with projects where they write difficult prompts, build answer rubrics and grade model outputs. Because the work is project-based and fully remote, contributors set their own hours with no minimum commitment.

The platform reports more than 900,000 experts onboarded and over $500 million paid out to contributors across 50 countries, with a large share of participants being graduate students and PhDs. Typical accounts describe a 30 to 90 minute onboarding flow covering account creation, expertise selection, skill screening and identity verification, after which project-specific training begins.

Outlier is part of the Scale AI family of data-labeling businesses, so the projects generally feed into real model-development pipelines rather than academic exercises. Pay is competitive and quality-based, disbursed weekly, and contributors sometimes get free access to paid frontier models as part of their work. Because project availability fluctuates, income is best treated as flexible supplementary earnings rather than a guaranteed full-time salary.

## Pricing & Plans

Free for experts to join. Outlier pays contributors for completed work rather than charging them; rates vary by project, expertise area and locale, with quality-based bonuses and weekly payouts.
