Interpreting Complex Behaviors of Powerful AI Models
By
–
This is an early step; there is a long path from this work to fully understanding the complex behaviors of our most powerful models. Our aim is to understand larger models, gradually expand the set of behaviors we can reliably interpret, and obtain safety assurances using our

Sparse Models Reveal Interpretable Task-Specific Components
By
–
Unlike with normal models, we often find that we can pull out simple, understandable parts of our sparse models that perform specific tasks, such as ending strings correctly in code or tracking variable types. We also show promising early signs that our method could potentially

Sparse Neural Networks Improve AI Model Interpretability Research
By
–
Most neural networks today are dense and highly entangled, making it difficult to understand what each part is doing. In our new research, we train “sparse” models—with fewer, simpler connections between neurons—to see whether their computations become easier to understand.

New Interpretable Training Method for Small Language Models
By
–
We’ve developed a new way to train small AI models with internal mechanisms that are easier for humans to understand. Language models like the ones behind ChatGPT have complex, sometimes surprising structures, and we don’t yet fully understand how they work. This approach
