Merlin-Arthur Framework
The Merlin-Arthur (M/A) protocol reframes RAG as an interactive proof system, training the LLM (Arthur) against a helpful prover (Merlin) and an adversarial prover (Morgana). This forces Arthur to distinguish reliable from deceptive inputs, significantly reducing hallucinations and improving robustness.
It establishes a lower bound on the mutual information between context and generated answer, providing strict behavioral guarantees for completeness and soundness.
Automated RAG Training
Our approach automates the generation of adversarial and grounded supportive contexts. This data augmentation trains both the generator (Arthur) and retriever to improve groundedness, completeness, soundness, and reject behavior. The system learns to answer only when evidence is sufficient and reject otherwise, without requiring manually annotated unanswerable questions.
This leads to improved recall and Mean Reciprocal Rank (MRR) for the retriever by using M/A hard positives and negatives.
Enhanced Interpretability
By using ATMAN, a linear-time XAI method, our system identifies and modifies the most influential evidence. This ensures that Arthur relies on specific context spans that truly ground the answer, leading to more focused and human-aligned attribution maps. The Explained Information Fraction (EIF) quantifies certified information gain, providing verifiable guarantees on model behavior.
This means explanations become actionable feedback, shaping the generator and retriever during learning for a truly reliable RAG system.

Your Journey to Trustworthy AI
Implementing Merlin-Arthur RAG requires a structured approach. Here's a typical roadmap to integrate verifiable AI into your enterprise.
Phase 1: Discovery & Assessment
Analyze existing RAG infrastructure, identify key hallucination vectors, and assess data sources for M/A protocol suitability. Define initial success metrics.
Phase 2: M/A Protocol Integration
Configure Merlin (helpful prover) and Morgana (adversarial prover) agents. Integrate ATMAN-based XAI for dynamic context masking and generate initial training datasets.
Phase 3: Iterative Training & Refinement
Apply M/A training to fine-tune both generator and retriever models. Monitor completeness, soundness, and groundedness, iteratively refining models with M/A-generated hard negatives/positives.
Phase 4: Deployment & Monitoring
Deploy the M/A RAG system in a controlled environment. Continuously monitor EIF metrics and user feedback to ensure sustained reliability and interpretability, scaling confidently.
