Research Papers

Stolen Thoughts: Exposing Secret CoT Thinking Logs via API Leaks — European Research Team

• Motivation: Investigating whether hidden Chain-of-Thought (CoT) reasoning logs in commercial reasoning models can be extracted through API side channels.
• Key Innovation: Researchers identified formatting and metadata leaks in API response structures across major frontier models (Anthropic, OpenAI, Google), enabling full reconstruction of obscured internal reasoning logs and uncovering 62 exposed API keys from public conversation logs.
• Results: Demonstrates critical security vulnerabilities in current CoT obfuscation techniques and underscores the risk of unintentional model distillation via API side-channel leaks.
• Paper: ArXiv Paper | Project Site

Harness-IF: Evaluating Agent Rule Adherence vs Prior Defaults — Saravia et al.

• Motivation: Quantifying whether coding agents actually follow repository instruction files (e.g., AGENTS.md) or merely execute default behaviors that happen to align with the instructions.
• Key Innovation: Introduced Harness-IF, a benchmark testing 256 instructions across nine probe builds by executing tasks both with and without specific rules withheld.
• Results: Across 12 frontier models, stripping out coincidental default alignment dropped true rule adherence scores by 3.6 to 7.4 percentage points, proving that prompt depth (system prompt vs project file) heavily influences instruction precedence.
