Intro

What is captum.ai?

Captum is an open-source model interpretability library built on PyTorch, designed to help researchers and developers understand how their neural networks make decisions. As a comprehensive framework for python captum implementations, it answers what is captum by offering advanced algorithms like captum integrated gradients, feature ablation, and gradcam captum to attribute model predictions to specific inputs. Whether you are seeking a captum saliency example, investigating how does captum integrated gradients work, or applying captum for llm architectures and transformer models, this library provides the diagnostic depth required for robust model evaluation.
