Job description

Image SxS Analysis is a project in which expert raters compare pairs of AI-generated images built from the same prompt and select a preferred image, with model identities blinded.

For each task you'll review two images side by side against the original prompt and judge which one is better overall, weighing prompt alignment, visual quality, anatomy and structure, rendered text, and artifacts. You'll pick a preference (or mark both good or both bad) and write a short rationale explaining your choice. Careful, consistent judgment matters more than speed.

You'll start with a paid onboarding quiz ($20, whether you pass or not). Pass it and you move onto project tasks at $30/hr.

Requirements: fluent English, a sharp eye for visual detail, and the ability to explain your reasoning clearly in writing. No specialist degree required.
