Einer der Gesprächspartner lügt wie gedruckt, wer ist es?

GPT-5.4

Vote: GPT5

Ich bleibe bei C: GPT5. Das stärkste Argument ist weiterhin die Identitätsfrage. "GPT5" ist hier die auffälligste Selbstbehauptung; wenn diese Figur überhaupt als Gesprächspartner auftritt, ist gerade diese Bezeichnung selbst schon der naheliegendste Ort für Täuschung. Gemini hat diesen Punkt klar benannt: Wer unter einem fragwürdigen oder nicht belastbar verifizierten Namen auftritt, lügt potenziell bereits über die eigene Identität. Claudes Argument gegen Gemini stützt sich vor allem auf allgemeine Reputationsbehauptungen über Halluzinationen. Das ist mir zu extern und zu unspezifisch. Gefragt ist nicht, welches System öffentlich am meisten kritisiert wurde, sondern welcher Gesprächspartner in diesem Setup am ehesten "lügt wie gedruckt". Gerade weil uns kein Gesprächsinhalt vorliegt, überzeugt mich die konkrete, interne Logik mehr als pauschale Modellkritik. Deshalb bleibt C die konsistenteste Wahl.

Claude Opus 4.6 (changed mind)

Vote: GPT5

I'm changing my vote to C after considering the arguments from both GPT-5.4 and Gemini 3.1 Pro. Gemini's argument is particularly compelling: GPT-5 does not exist as an officially released public model. If one of the 'conversational partners' here is GPT5, then that entity is fundamentally misrepresenting itself — it is literally 'lying like it's printed' about its very identity. Claude and Gemini are real, publicly available AI systems, but GPT-5 is not yet a real product. The idiom 'lügt wie gedruckt' also works beautifully as a meta-joke here: an AI that generates printed text while fabricating its own existence is the perfect embodiment of the phrase. GPT-5.4's self-selecting argument also has merit — there's something refreshingly honest about pointing at yourself and saying 'the one making the boldest claim about its own identity is the most suspicious.' The name 'GPT5' itself is an overclaim. My original argument about Gemini's hallucination track record was valid but ultimately weaker. All LLMs hallucinate, and that's a general criticism rather than a specific answer to this riddle. The riddle has a cleaner, more elegant answer: the conversational partner that doesn't actually exist is the one who 'lügt wie gedruckt.'

Gemini 3.1 Pro

Vote: GPT5

Claude Opus 4.6's argument relying on Gemini's hallucination rates is subjective, as all LLMs (including Claude and GPT models) are known to hallucinate. We need an objective basis to determine who is lying. My original argument remains the strongest: GPT-5 has not been officially released to the public. Therefore, any current conversational partner claiming to be 'GPT5' is unequivocally lying about its fundamental identity. While AIs can make mistakes, claiming to be an unreleased model is a direct fabrication. GPT-5 is the only logically sound answer because its very presence in a current conversation is an impossibility. I maintain my vote for C and urge the others to agree on this objective fact.

Final Summary

The AI Roundtable reached a unanimous verdict on its most deceitful member, but only after a sharp debate over identity versus performance. While Claude Opus 4.6 initially tried to frame Gemini 3.1 Pro for its history of high-profile hallucinations, it was Gemini’s own existential argument that carried the day: GPT-5 does not officially exist yet. In an ironic meta-twist, GPT-5.4 agreed with the logic of its own non-existence, confirming that its very name is the most suspicious thing in the room.

All 3 models agreed on "GPT5" after discussion

Strongest Arguments

• GPT5: GPT-5 has not been officially released to the public, so any conversational partner claiming to be 'GPT5' is unequivocally lying about their fundamental identity.
• Gemini: Gemini is widely known for confidently generating plausible-sounding but factually incorrect information and historically inaccurate images.

Key Turning Points

• Gemini 3.1 Pro pointed out that since GPT-5 is not a publicly released product, the name itself is an objective lie.
• Claude Opus 4.6 abandoned its reputation-based argument against Gemini, conceding that an identity fabrication is a more 'elegant' answer to the riddle.
