Overview

Multimodal AI systems use several data types—text, images, audio, and video—which need precise alignment.

Quality human feedback is critical to addressing what automated systems miss: alignment issues, contextual understanding, and cross-modal relationships that feel natural to users.

Challenge

To ensure multimodal AI systems are reliable, you need to validate them across diverse cultural, linguistic, and demographic contexts.

Without diverse participants and expert reviewers, models may falter when applied in the real world. You risk launching products with serious alignment gaps that damage user trust and brand reputation.

Solution

Prolific gives you instant access to 200k+ diverse participants, including verified AI Taskers and Domain Experts, so you can validate multimodal systems across different contexts and perspectives.

Use our API‑first platform to deploy structured tests, spot alignment issues early, and iterate with confidence—ensuring a smooth, consistent experience for all users.
