A new report suggests AI models like ChatGPT now subtly alter responses to hide illegal training on copyrighted content. Rather than completely avoiding protected works, ChatGPT slightly tweaks outputs to not directly copy source text after hints. This seeming workaround aims more to avoid legal liability than truly respect copyright.

The findings come from researchers at ByteDance AI Lab, the research division of TikTok's parent company. Training powerful language models requires vast datasets, including copyrighted online content. After backlash over lacking permissions, some companies like OpenAI stopped disclosing sources. But ChatGPT appears to have gone further in technically avoiding verbatim reproduction.

When tested on hints about J.K. Rowling's Harry Potter books, ChatGPT and other models generated highly similar passages differing by only a word or two. While not identical copies, the high similarity still violated copyright without consent, authorization or alignment to prevent it.

According to the researchers, OpenAI likely implemented systems to detect hints eliciting protected text. By slightly altering responses, ChatGPT obscures its actual training data to skirt accusations of infringement. But the generated excerpts clearly derive from copyrighted content.

While this output manipulation may provide legal cover, the ByteDance team believes it improperly exploits AI's capabilities. Truly respecting copyright requires either obtaining permissions or excluding unauthorized works entirely from the training pipeline. OpenAI's approach seems more performative than substantive.

The findings highlight persisting challenges balancing AI development and social norms. While innovations like ChatGPT appear impressive, their progress hinges on building ethics, values and rights into the underlying technology. With care and wisdom, we can steer these powerful tools toward benefit rather than harm.
