Microsoft Forced LLMs to Forget About Harry Potter

Microsoft has revealed a method for instructing Large Language Models (LLMs) to forget specific information within their datasets without requiring a full reconstruction of the training data. This method opens up new possibilities for improving LLMs and potentially resolving legal issues involving copyrighted content.

Microsoft’s team recently demonstrated how they were able to make the Llama-2 model forget the details of the Harry Potter books without affecting other data in the model’s training data or the model’s overall performance in a study described on their research project page.

The process begins with the identification of specific information within the model’s dataset that needs to be forgotten. In this case, it was details related to J.K. Rowling’s iconic series, including plot specifics, character names, and famous quotes. These were then systematically replaced with generic, unrelated phrases.

The researchers then employed a language model to generate new information based on this generic data. This fresh data was then used to retrain the original Llama-2 model incrementally. With each step, the model distanced itself from the Harry Potter books until it began producing hallucinatory responses when questioned about them.

One striking feature of this approach is that it does not compromise the model’s general performance. This means that while the LLM becomes increasingly forgetful about specific data, its overall language capabilities remain intact.

Despite the fact that this approach is still being refined, its implications are wide-ranging. In situations involving legal claims and copyright issues, in particular, it may provide a lifeline to those creating LLMs and other AI models.

This innovation comes at a time when legal disputes over the use of copyrighted content in AI models are on the rise. For instance, The New York Times recently demanded the removal of its publications from the GPT-4 dataset. In the event of a successful legal challenge, developers would typically need to reconstruct their model datasets, a time-consuming and resource-intensive process. Microsoft’s method, if further refined and adopted, could provide an efficient solution to such challenges.

Microsoft’s method to selectively forget specific information within Large Language Models (LLMs) is a significant breakthrough in AI development, potentially addressing copyrighted content issues and streamlining refinement. This approach could be applied to various domains, demonstrating responsible AI development and application.
