Computer science professor and founder of modern reinforcement learning Rich Sutton said in his essay “ [The Bitter Lesson](https://www.cs.utexas.edu/~eunsol/courses/data/bitter_lesson.pdf)” about AI, “Breakthrough progress eventually arrives by an opposing approach based on scaling computation by search and learning.” The breakneck progress of AI model development in the last three years is a testament to that lesson. As models, be it large language models or diffusion models, get bigger and better, they become more and more opaque. A black box. As these models get deployed in the world, they make critical decisions that impact all of our lives. Decisions which we frankly don’t understand. Would you be comfortable being in a plane where you don’t know how the autopilot system behaves? I wouldn’t.
When we first met with the [Goodfire](https://www.goodfire.ai/) team, that was precisely the problem they’d set out to solve. They brought together a set of the strongest AI researchers and engineers to answer the question: Can we figure out why AI models behave the way they do? Can we steer that behavior? Goodfire is a company focused on core mechanistic interpretability research—the relatively nascent science of reverse engineering neural networks and using those insights to ste
