Mechanistic interpretability — understanding the inner workings of large language models — is becoming an increasingly important field. Tools like Gemma Scope and the open-source library Mishax provide insights into the Gemma2 family of open models. Interpretability tools play a crucial role in debugging unexpected behavior, identifying components responsible for hallucinations, biases or other failure cases, and ultimately building trust by offering deeper visibility into models. While this field may be of particular interest to researchers, it's worth noting that with the recent release of DeepSeek-R1, model training is becoming more feasible for companies beyond the established players. As GenAI continues to evolve, both interpretability and safety will only grow in importance.
