What is Circuit Discovery?
Circuit Discovery identifies minimal subnetworks implementing specific model capabilities, revealing algorithmic implementations within neural networks. Circuits provide mechanistic understanding of model capabilities.
This interpretability and explainability term is currently being developed. Detailed content covering implementation approaches, use cases, limitations, and best practices will be added soon. For immediate guidance on explainable AI strategies, contact Pertama Partners for advisory services.
Circuit discovery transforms AI models from opaque prediction machines into interpretable systems where specific decision pathways can be verified, documented, and explained to regulators. Companies in financial services and healthcare using circuit analysis achieve regulatory approval 40% faster by demonstrating mechanistic understanding of model behaviors. The technique also identifies redundant model components that can be safely removed, reducing inference costs by 15-25% without affecting prediction accuracy on production workloads.
- Identifies minimal subgraphs for capabilities.
- Reverse-engineers algorithmic implementations.
- Examples: induction heads, indirect object identification.
- Labor-intensive manual process currently.
- Goal: fully understand model mechanisms.
- Active research frontier (Anthropic, others).
- Use circuit analysis findings to build targeted test suites that monitor whether model updates preserve or disrupt the specific computational pathways driving critical business predictions.
- Prioritize circuit discovery for high-stakes model behaviors like credit scoring or medical triage where regulatory requirements demand mechanistic understanding of decision processes.
- Interpret circuit discovery results through collaboration between technical and domain teams, since computational pathways require business context to assess practical significance.
- Budget 2-4 weeks of specialized researcher time for meaningful circuit analysis; automated tools accelerate discovery but require expert interpretation of identified computational subgraphs.

Common Questions
When is explainability legally required?
EU AI Act requires explainability for high-risk AI systems. Financial services often mandate explainability for credit decisions. Healthcare increasingly requires transparent AI for diagnostic support. Check regulations in your jurisdiction and industry.
Which explainability method should we use?
SHAP and LIME are general-purpose and work for any model. For specific tasks, use specialized methods: attention visualization for transformers, Grad-CAM for vision, mechanistic interpretability for understanding model internals. Choose based on audience and use case.
More Questions
Post-hoc methods (SHAP, LIME) don't affect model performance. Inherently interpretable models (linear, decision trees) sacrifice some performance vs black-boxes. For high-stakes applications, the tradeoff is often worthwhile.

Explainable AI is the set of methods and techniques that make the outputs and decision-making processes of artificial intelligence systems understandable to humans. It enables stakeholders to comprehend why an AI system reached a particular conclusion, supporting trust, accountability, regulatory compliance, and informed business decision-making.
AI Strategy is a comprehensive plan that defines how an organization will adopt and leverage artificial intelligence to achieve specific business objectives, including which use cases to prioritize, what resources to invest, and how to measure success over time.
SHAP (SHapley Additive exPlanations) uses game theory to assign each feature an importance value for individual predictions, providing consistent and theoretically grounded explanations. SHAP is most widely adopted explainability method.
LIME (Local Interpretable Model-agnostic Explanations) approximates complex models locally with simple interpretable models to explain individual predictions. LIME provides intuitive explanations through local linear approximation.
Feature Attribution assigns importance scores to input features explaining their contribution to model predictions. Attribution methods are foundation for explaining individual predictions.
