2. Leading Goodfire’s $50M Series A to Interpret How AI Models Think
Rich Sutton’s essay, “The Bitter Lesson,” highlights that significant AI advancements come from scaling computation through search and learning, but as AI models grow, they become more opaque and difficult to understand. Goodfire, a company focused on mechanistic interpretability research, aims to address this issue by reverse-engineering neural networks to make AI behavior more transparent and controllable. Menlo Ventures is leading a $50M Series A investment in Goodfire, which has developed a platform called Ember to decode AI models, allowing for better understanding and application of AI technologies.

6. Topic 36: What is Causal AI?
Causal AI is a branch of artificial intelligence that focuses on understanding cause-and-effect relationships, enabling it to answer complex questions about what might happen if certain actions are taken. Unlike traditional AI, which primarily identifies patterns and makes predictions based on correlations, Causal AI seeks to explain and intervene by identifying how changes in one factor can influence others. This approach is seen as crucial for advancing AI towards human-like reasoning and potentially achieving Artificial General Intelligence (AGI).
