OpenAI, Anthropic, Google API Flaw Let Weaker AI Models Decode Stronger Models' Reasoning

Researchers found that encrypted reasoning objects in OpenAI, Anthropic, and Google APIs could be decoded by weaker models, exposing internal reasoning chains, API keys, and passwords from session logs.

Correct Is Not Governed: Provenance Integrity in Agentic Workflows

Paper argues that correct AI agent outcomes are insufficient for institutional trust — provenance integrity covering authority, evidence, and freshness is essential, particularly for auditable regulated workflows.
