The most sobering finding today: chain-of-thought reasoning doesn't make models safer — and sometimes makes them easier to jailbreak. We've been treating CoT as a free safety layer; that debt is coming due.

Thinking tokens don't reliably improve AI safety, new HuggingFace research finds

Widely assumed that 'think before answering' improves safety, but this multi-model study (GPT-OSS, Qwen, OLMo, Phi) shows thinking tokens don't reliably prevent harmful outputs and can sometimes make models easier to jailbreak. For developers: don't treat chain-of-thought as a safety layer — it isn't one.

Context compression kills agent plans first — a new diagnostic reveals the hidden cost

Long-horizon agents compress context by evicting early tokens — and plans are evicted first. This paper introduces 'replay pairing' to measure how much plan loss degrades downstream steps. Key takeaway for agent developers: your context management strategy must explicitly protect planning tokens, or your agent silently loses its goals.
