Explainability
- Definition
- The ability to understand and articulate why an AI model produced a specific output. Regulators increasingly demand explainability in high-stakes domains like healthcare, finance, and criminal justice.
- Why it matters
- Explainability is becoming a legal requirement, not just a nice-to-have. The EU AI Act mandates transparency for high-risk AI systems. Financial regulators require explanations for AI-driven lending and insurance decisions. Healthcare systems need to justify AI-assisted diagnoses. Beyond compliance, explainability builds user trust: people adopt AI tools faster when they understand why the AI made a particular recommendation. The challenge is that modern neural networks are inherently opaque, as millions of parameters interact in ways no human can trace. This creates a fundamental tension between model capability (more parameters, more layers) and interpretability.
- In practice
- Anthropic published groundbreaking interpretability research in 2024, identifying individual features in Claude that correspond to specific concepts (like the Golden Gate Bridge), demonstrating that neural network internals can be partially decoded. Google's PAIR team developed tools for visualizing attention patterns and feature attributions. In regulated industries, companies often use simpler, interpretable models (logistic regression, decision trees) for final decisions, with LLMs as preprocessing or augmentation layers. SHAP and LIME remain popular post-hoc explanation tools. The gap between research interpretability and production explainability requirements remains significant.

Bias (in AI)
Systematic errors in model outputs that reflect skewed training data or flawed design choices. Bias can lead to unfair outcomes in hiring, lending, and content moderation, creating legal and reputational risk.
Responsible AI
A framework for developing and deploying AI systems that are ethical, transparent, and accountable. Responsible AI practices are becoming table stakes for enterprise procurement and regulatory compliance.
AI governance
The organizational frameworks, policies, and processes that govern how AI systems are developed, deployed, monitored, and retired within an enterprise. AI governance covers model risk management, bias auditing, access controls, and regulatory compliance.
Fairness
The principle that AI systems should produce equitable outcomes across demographic groups. Achieving fairness requires careful dataset curation, evaluation metrics, and ongoing auditing.
