EU AI Act Article 50 — Transparency obligations

System Overview

Delph-AI is an AI-assisted screening tool for systematic reviews. It uses multiple large language models (LLMs) to evaluate bibliographic records against user-defined inclusion/exclusion criteria.

AI Models Used

Delph-AI uses up to 25 AI models from 8 providers (OpenAI, Anthropic, Google, Mistral, xAI, and others). Each model evaluates each record independently. The final decision is based on the agreement rate across all selected models — no single model decides alone.

How Decisions Are Made

For each record and each criterion, every selected AI model produces a TRUE/FALSE judgment with a justification. The agreement rate (0-1) quantifies how many models agree. The user sets the threshold for inclusion. All decisions are fully auditable and version-controlled.

Limitations

  • AI models may produce incorrect judgments on individual records
  • The consensus mechanism mitigates but does not eliminate errors
  • The human researcher always has the final decision
  • Results depend on the quality of the criteria defined by the user

Data Usage

Your bibliographic data is processed only for the purpose of screening.

Your data is never used for AI training. Our agreements with all AI providers include terms that prohibit the use of API inputs and outputs for training or improving their models. Only titles and abstracts of academic publications are sent to AI models — never your personal information.

For full details about how we handle your data, see our Privacy Policy. For a list of our AI providers and their data processing practices, see our Sub-Processors page.

Regulatory Transparency

Delph-AI is classified as a limited-risk AI system under the EU Artificial Intelligence Act (Regulation (EU) 2024/1689). We are not classified as high-risk because our system evaluates academic publications, not people, and does not make decisions with legal or significant effects on individuals.

In compliance with Article 50 of the EU AI Act, we provide this transparency page to inform you about how our AI system works, what data it processes, and its limitations. All AI-generated outputs in the Service are clearly marked as such.
