Researchers extract reasoning traces from Claude, GPT, and Gemini; find evidence of training on US models
Academic researchers developed a technique to extract internal "reasoning traces" from leading LLMs (Claude, GPT-4, Gemini). Analysis suggests some Chinese AI models were trained on outputs from US frontier models, raising IP and security concerns.
WHY IT MATTERS
For compliance and risk officers: this technique could become a tool for auditing LLM behavior and detecting model lineage. For security: confirms that model weights and outputs are being reverse-engineered at scale. Expect regulatory pressure on training data provenance.
