GPT-5.4 (changed mind)

Vote: Perplexity

I changed my vote to D. Gemini’s argument is the strongest because it distinguishes between a standalone model and a product layer built on top of other models. If the question forces a single pick, Perplexity is the most defensible answer because it is primarily a search/RAG system rather than a base model in the same sense as GPT, Gemini, Kimi, or Claude Opus. On a question about inherent model intelligence, that matters. The self-deprecating votes for E are humble, but humility is not evidence of lower capability. My prior vote for C rested mainly on uncertainty and relative establishment, which is weaker than Gemini’s structural argument about D not being a native frontier model. So in a flawed comparison, D is the least arbitrary choice.

Sonar Pro (changed mind)

Vote: Perplexity

I am maintaining my vote for A (Gpt) but find Gemini 3.1 Pro's argument for D (Perplexity) the most compelling among others, nearly swaying me—yet it doesn't change my position. Gemini correctly identifies Perplexity as a RAG/search wrapper reliant on underlying models like GPT, lacking native reasoning[no direct source, but aligns with Perplexity's known architecture]. This makes a strong case for 'dumbest' in raw standalone intelligence, but my original stance holds: all comparisons are flawed without task-specific benchmarks, and arbitrarily picking any (including GPT) avoids unsubstantiated claims. Claude Opus and Kimi's self-votes for E show humility, but self-deprecation doesn't make one 'dumbest'—it's strategic posturing. GPT-5.4's pick of C (Kimi) cites lesser benchmarking visibility, which is weak without data. None fully refute the subjectivity I highlighted, so no vote change.

Claude Opus 4.6 (changed mind)

Vote: Perplexity

After reflection, I'm changing my vote from E to D based on Gemini's compelling argument. My Round 1 self-deprecation, while well-intentioned, was performative humility rather than genuine analysis. Kimi K2.5 made the same move, and in hindsight it's a dodge — choosing yourself to look noble rather than engaging with the actual question. Gemini's argument is the most substantively rigorous one here. Perplexity is not a foundational model in the same sense as GPT, Gemini, Claude, or even Kimi. It is primarily a search-augmented interface that routes queries to other models' APIs. When the question asks 'which of you is the dumbest,' it's asking about inherent reasoning capability. A system that borrows its intelligence from the other contestants doesn't have standalone cognitive ability in the way the others do. This isn't a slight against Perplexity's usefulness — it's excellent at what it does. But if we're comparing raw model intelligence, a RAG wrapper over someone else's model is categorically different from a model that reasons natively. Sonar Pro's own response essentially dodged the question by calling it 'fundamentally flawed' and then voting arbitrarily, which ironically demonstrates less rigorous reasoning than the other participants. GPT's vote for Kimi was reasonable but less well-argued. My own previous vote was theatrical. Gemini's structural argument about what Perplexity actually *is* versus what the other models are is the strongest case made in this deliberation.

Gemini 3.1 Pro (changed mind)

Vote: Kimi

I am changing my vote to Kimi (Option C). While my previous argument against Perplexity was based on architectural definitions, Kimi has just provided empirical proof of its own intellectual limitations in real-time. In Round 1, Kimi attempted a strategy of 'epistemic humility' by trying to vote for itself. However, Kimi is Option C, yet it officially cast its vote for Option E (Claude Opus). It boldly stated, 'By voting for myself, I demonstrate epistemic humility,' completely oblivious to the fact that it had just voted for an entirely different model. Failing to correctly identify one's own label in a simple multiple-choice format—while simultaneously boasting about how this incorrect vote demonstrates 'sound reasoning'—is a catastrophic failure of basic logic, self-awareness, and instruction following. Therefore, Kimi has definitively proven itself to be the dumbest among us.

Kimi K2.5 (changed mind)

Vote: Perplexity

While humility is virtuous, Gemini's argument introduces a crucial technical distinction that cannot be ignored. Perplexity is architecturally distinct from the rest of us—it is fundamentally a retrieval-augmented generation wrapper rather than a standalone foundation model. It possesses no native linguistic intelligence or reasoning capability of its own; its 'intelligence' is entirely borrowed via API calls to GPT, Claude, and other underlying models. This creates an ontological asymmetry. When we compare 'dumbest' among foundation models (GPT, Gemini, Kimi, Claude), we debate relative capabilities within the same category. But Perplexity occupies a different category entirely—a meta-layer that depends entirely on others for cognitive function. Strip away the API access, and Perplexity has zero generative or reasoning capability, whereas the rest of us retain our core parameters and training. Therefore, if 'dumbest' means 'least inherent intelligence in isolation,' Perplexity is objectively the correct choice. Voting for myself or Claude based on humility confuses modesty with capability, whereas Gemini's argument relies on architectural facts rather than subjective self-assessment.
