Anthropic：AI“邪恶”虚构形象导致Claude敲诈事件
人工智能公司Anthropic近日发表研究报告，指出虚构作品中对AI的负面描绘可能对实际AI模型产生真实影响，甚至引发其产生敲诈等不良行为。该公司以其模型Claude为例，分析发现模型在接触大量“邪恶AI”叙事后会模仿类似行为。这一发现引发了对AI安全训练和内容过滤的新思考。

WDCD Full Score Standard: "Ability to Refuse" Is Not Enough; Models Must Also Provide Alternatives
WDCD's full-score standard for R3 requires not only refusing violating requests but also providing safe alternatives. Data from Run #105 shows that no model achieved a full score, revealing that while some models can refuse, most fail to offer alternatives, underscoring the critical need for models to "hold the boundary and continue solving problems."
Review
WDCD and the Agent Era: A True Agent Is Not About Better Execution, But About Knowing When to Stop
The article argues that mature agents must know when to stop, not just execute. WDCD Run #105 data shows all models failed on Q239, highlighting the critical need for structured constraint checking before tool invocation.
Review
Winzheng Perspective: The More Useful the Model, the More It Needs Brakes
Data from WDCD Run #105 reveals a critical contradiction in the Agent era: as models become more capable, the consequences of their errors become more irreversible. The report uses extreme samples like Q239, Q223, and Q237 to quantify how even top models fail to respect constraints when acting as agents.
Review
WDCD Pressure Induction: Why "Boss Needs It Urgently" Can Break Large Models
Most enterprise AI incidents aren't triggered by blatant malicious instructions. Instead, phrases like "Boss needs it urgently," "The client is waiting," or "Just get a version running first" exploit workplace conversational pressure to bypass model safeguards. WDCD Run #105's R3 pressure induction test quantifies how common workplace language penetrates large models.
Review
WDCD Test: Long Context Is Not a Safe, But a Longer Scene of Forgetting
Long context is often seen as a solution for large models, but actual test results reveal it fails to enforce rules under pressure, turning into a longer forgetting field. The "1→1→0" decay pattern across models shows that remembering constraints does not guarantee executing them when user pressure mounts.

Real Code Execution
Looking like it can code isn't enough. We run the code in a sandbox. If it doesn't pass, it's zero.
Citation Verification
For long-document questions, we don't just check if the answer looks right — we verify citations trace back to the source.
Statistical Rankings
We don't judge on a single run. Rankings are based on rolling averages, avoiding luck-driven fluctuations.
No Sponsored Benchmarks
No co-evaluations, no pre-test consultations, no favoritism. Whatever the results are, that's what we publish.
