OpenAI, Anthropic, and Google LLM APIs vulnerability Exposes Hidden Reasoning Traces

A significant architectural flaw in how major AI providers, including OpenAI, Anthropic, and Google, protect the internal “chain-of-thought” reasoning generated by their flagship large language models (LLMs). The research reveals that encrypted reasoning envelopes returned by provider APIs can be replayed into weaker, less-guarded sibling models to extract private reasoning traces in plain text.
