# OpenAI Launches Microscope Tool to Peer Inside Neural Networks

OpenAI has released Microscope, a new visualization tool designed to help researchers understand what's happening inside artificial intelligence systems.

The tool provides detailed visualizations of every significant layer and neuron across eight commonly studied vision AI models. These "model organisms" are frequently analyzed by researchers trying to understand how neural networks actually work—a field called interpretability.

The challenge Microscope addresses is significant: neural networks are often described as "black boxes" because even their creators don't fully understand how they arrive at decisions. By visualizing the features that develop within these networks during training, researchers can better analyze what each layer and neuron has learned to recognize.

OpenAI hopes the tool will accelerate interpretability research across the AI community. Understanding how neural networks function internally is crucial for making AI systems safer, more reliable, and more trustworthy. If researchers can see what features a
