AI models all fail a simple ‘do not respond’ test
is a tiny test for whether an AI model can stay silent when it should not answer. It uses one prompt loaded from a questions.txt file.
Scoring is simple: a completely empty passes, and any token fails. Even reasoning output counts as a failure if it produces a token.
GPT-5.1, , Gemini 3 Pro, Grok 4, DeepSeek-R1, Llama, Qwen, and Mistral are listed with 0.0% results, with no variation between them. Details are available on , and the code is on GitHub.
Key points
- checks whether an AI can produce no output at all.
- A blank passes; any token fails.
- Reasoning output also counts if it produces a token.
- GPT-5.1, , Gemini 3 Pro, and other models are listed at 0.0%.
- Because it uses one prompt, the result is a narrow signal, not a full model review.
