OpenAI unveils a new methodology to explain the inner workings of AI models.

In an effort to increase the transparency and safety of its technologies, OpenAI has published a new research paper outlining an innovative methodology to analyze the inner workings of AI models, such as GPT-4, which power ChatGPT. This research comes after some former employees criticized the company for its perceived risky approach to AI development.

In the paper, OpenAI researchers present a technique to identify how AI models store and utilize certain concepts. This methodology relies on an additional machine learning model to observe patterns within the systems of interest. Specifically, the innovation lies in refining the network used to examine these concepts, making the process more efficient.

OpenAI’s research demonstrated the effectiveness of this technique by identifying patterns within GPT-4, one of its most advanced AI models. The company also released the code related to this interpretability work and a visualization tool that allows users to see how words in different sentences activate specific concepts within the model, including profanity and erotic content. Understanding how a model represents certain concepts could be a step towards mitigating unwanted behaviors and ensuring the AI system operates safely and under control.

Despite these advances, the research highlights persistent challenges. The developed technique requires further refinement to be reliable on a large scale. Additionally, the research team that conducted this study was previously known as the "superalignment team," dedicated to studying the long-term risks of AI technologies, but it was recently disbanded.

AI explainability is a growing field aimed at making AI systems more comprehensible and predictable. Various competing companies, such as Anthropic supported by Amazon and Google, are conducting similar research. For instance, Anthropic created a chatbot focused on San Francisco’s Golden Gate Bridge to demonstrate how AI systems’ behavior can be modulated.

OpenAI’s research also emphasizes the need to configure smaller neural networks to better understand the components of larger ones. However, many technical details still need to be refined to provide fully comprehensible and reliable explanations. Professor David Bau from Northeastern University, an expert in AI explainability, commented that while the research represents exciting progress, there is still much work to be done to use these methods to create fully understandable explanations.

This initiative by OpenAI represents a significant step towards greater transparency and safety of AI models, making the work done to control and explain these advanced technologies more visible.
