🥇 Stealing Reasoning Traces from Proprietary LLM APIs

simonwillison.net · 23h ago · 🔒 Security

A new paper demonstrates a practical attack on proprietary LLM APIs (Anthropic, OpenAI, Google) by exploiting encrypted chain-of-thought (CoT) blocks that can be replayed across sessions, users, and models. The researchers take a trace from a frontier model, replay it into a weaker sibling model, jailbreak the weaker model, and recover the stronger model's hidden reasoning in plaintext. This reveals that encrypted CoT blocks are not secure against replay attacks, undermining the promise of hidden reasoning. The attack is demonstrated with a simple curl command, showing the vulnerability is easily accessible. The core issue is that encryption alone does not protect reasoning traces from being extracted via model-to-model transfer.

💡 Why it matters: This is a critical security finding that exposes a fundamental flaw in how leading AI vendors protect their models' reasoning, with direct implications for API security and trust in proprietary LLMs.

🥈 Pluralistic: Model collapse (12 Aug 2026)

pluralistic.net · 13h ago · 🤖 AI / ML

Cory Doctorow's 'Model collapse' discusses the phenomenon where AI models trained on data generated by other AI models degrade over time, leading to a loss of diversity and quality. He argues that this 'training on your own output' creates a feedback loop that amplifies biases and errors, ultimately making models less useful and more homogenized. Doctorow connects this to broader issues of monoculture and the 'insurance value of biodiversity' in AI ecosystems. He suggests that maintaining diverse, human-generated data sources is essential to prevent model collapse. The post also includes links to other delights and updates on his appearances and books.

💡 Why it matters: This is a timely and accessible explanation of a critical AI risk (model collapse) that is often overlooked, with implications for anyone relying on AI-generated content or models.

2. There are no lossless transformations of natural-language text¶

Link — simonwillison.net · 22h ago · ⭐ 22/30

Sophie Alpert shares her 'internal policy on acceptable use of AI writing by engineers,' arguing that there are no lossless transformations of natural-language text. She emphasizes that engineers must stand behind every idea and sentence in their docs, ensuring the document represents their own thoughts before sharing. The policy allows LLM assistance for editing but not for generating new ideas or content. Alpert's rule is that AI can help massage writing but not replace the author's intent. The post is a short, practical guide for teams navigating AI use in technical writing.

7. The Economist: ‘How to Spot AI Writing’¶

Link — daringfireball.net · 1 days ago · ⭐ 23/30

The Economist conducted a study to identify hallmarks of AI writing by comparing its own human-written prose with output from top LLMs (ChatGPT, Claude, Gemini, Grok). The study found that AI writing tends to be more formulaic, with predictable sentence structures and a lack of distinctive voice. Specific markers include overuse of certain transitional phrases and a tendency toward generic, 'safe' language. The article provides concrete examples and analysis to help readers spot AI-generated text. The conclusion is that while AI writing is improving, it still lacks the nuance and originality of human journalism.
