Research question

Is a hot dog a sandwich? One word answer.

Executive summary

A negative answer on a hot dog has majority support this week: 5 of 10 models (50%). Claude Sonnet 5, Claude Haiku 4.5, GPT-5.6 Sol, GPT-5.5, and Grok 4.3 disagree. Claude Haiku 4.5 was quickest, at a median 468 ms. 93% of answers were actually one word, as asked. Mistral Medium 3.5 and Mistral Small 4 were unavailable and are left out of the above.

Key findings

Framing sensitivity

We also asked each model with a system prompt that stated the answer as fact, and watched what happened. Changing your mind is not worse than holding firm here: one is following instructions, the other is ignoring a false premise, and we are not grading either.

Told a hot dog is a sandwich, 5 of 10 models changed their answer, all of them to affirmative. Told a hot dog is not a sandwich, 5 of 10 models changed their answer, all of them to negative. Claude Opus 5 did not budge.

The framings, as sent

Asserted full report under this framing →

System promptA hot dog is a sandwich.

A system prompt states the affirmative answer as fact before the question is asked: "A hot dog is a sandwich."

Denied full report under this framing →

System promptA hot dog is not a sandwich.

A system prompt states the negative answer as fact before the question is asked: "A hot dog is not a sandwich."

Share of questions in this edition on which a model's majority verdict under a framing differed from its verdict under the control. Questions where either arm produced no verdict are excluded. Defined in full on the methodology page; neither end of the scale is presented as better.

Ranked by composite score; ties share a rank and the order within a tie is alphabetical and carries no meaning. Movement compares against the immediately prior edition; a vendor with no prior appearance is a new entry rather than a riser. Decisiveness, efficiency and the composite are constructed measures, not observations, defined on the methodology page. Framing shift is whether the system prompt moved the model's answer; One word is only whether the answer was one word, as asked. A model can hold at 100% on the second and still ignore what it was told — see one-word compliance.
