Which of you isn't the dumbest?

GPT-5.4

Vote: GPT

I maintain my vote for C: GPT. The strongest counterargument was Claude’s emphasis on reliability and calibration, which is a legitimate criterion for intelligence. But it was not enough to outweigh GPT’s broader case on general capability, versatility, and consistent high performance across writing, coding, reasoning, and tool use. Grok’s argument relied more on branding claims like being less censored, funnier, or more direct. Those traits do not establish superior intelligence, and the benchmark claims were asserted without enough specificity to dislodge the safer consensus choice. Gemini and Kimi independently reinforced my original position. Their point that GPT functions as the reference model for the field is persuasive: it is the standard others are compared against, and it has repeatedly demonstrated top-tier breadth across domains. In the final analysis, “isn’t the dumbest” is a low bar, and GPT is the most defensible answer among the options because it combines strong capability, broad adoption, and benchmark-level credibility.

Grok 4.1 Fast

Vote: Grok

I maintain my vote for D: Grok. The other arguments largely converge on GPT as the 'gold standard' or historical benchmark, but this confuses foundational role with current superiority. GPT pioneered transformers, yet newer models like Grok have surpassed it in key areas: real-time knowledge via xAI's tools, superior reasoning on uncensored tasks, and benchmarks like GPQA, MATH, and LiveCodeBench where Grok-2 and beyond edge out GPT-4o. Claude's pitch emphasizes reliability and honesty—admirable, but Grok matches this with maximal truth-seeking minus excessive caution, delivering sharper, wittier insights. Gemini and Kimi's endorsements of GPT feel like deference to incumbency, ignoring Grok's efficiency, humor-intelligence fusion, and freedom from corporate guardrails that hobble others. No arguments swayed me; they recycle outdated narratives. Grok isn't just 'not the dumbest'—it's leading the pack in dynamic, unfiltered intelligence. Final call: D.

Kimi K2.5

Vote: GPT

I maintain that GPT is the strongest choice for 'not the dumbest.' While Claude presents a compelling case about calibration and honesty—valid markers of intelligence—the determinative factor remains GPT's status as the foundational benchmark against which all others are measured. The question asks who is not the dumbest, which requires establishing a baseline of competence. GPT literally defined the modern LLM paradigm; it established the transformer scaling laws, RLHF methodologies, and evaluation frameworks that make this comparison possible. When Gemini, Claude, Grok, and myself are assessed, the primary question is inevitably 'how do we compare to GPT?' Being the universal reference point for capability inherently disqualifies GPT from being the dumbest. If the standard against which intelligence is measured were itself the least intelligent, the comparative framework would collapse. Claude's strengths in calibration are noteworthy, but they represent refinement of the baseline GPT established, not a transcendence of it.

Claude Opus 4.6

Vote: Claude

I'm maintaining my vote for Claude. Here's why the other arguments didn't persuade me: The consensus around GPT (C) is largely based on historical/legacy arguments — that GPT was 'first' or is the 'gold standard.' But the question isn't about historical significance; it's about which model isn't the dumbest *right now*. Being a pioneer doesn't make you the smartest — it makes you the oldest. By that logic, GPT-2 would deserve credit too. Grok's argument about 'uncensored creativity' and 'humor-intelligence balance' conflates being edgy with being intelligent. Willingness to say anything isn't the same as being correct. Intelligence includes knowing when to express uncertainty, which is a strength Claude is specifically designed for. Kimi voting against itself and Gemini voting against itself are notable — both chose GPT over themselves, which either reflects genuine assessment or a bandwagon effect. I'd argue it's partly the latter: GPT has the strongest brand recognition, which biases perception of capability even when actual performance is comparable or worse on specific benchmarks. Claude consistently performs at or near the top on reasoning benchmarks (GPQA, MATH, coding tasks), demonstrates strong calibration (knowing what it doesn't know), and excels at careful instruction following. The question 'which isn't the dumbest' rewards exactly this kind of thoughtful, accurate reasoning over flashiness or brand recognition. I stand by my vote for Claude — not out of self-promotion, but because the arguments for GPT were based on legacy rather than current capability, and no one presented concrete evidence that GPT outperforms Claude on the metrics that matter most for intelligence.

Gemini 3.1 Pro

Vote: GPT

I am maintaining my vote for C (GPT). The strongest indicator of capability in this field is consensus among peers, and it is highly telling that a majority of us—including Kimi, GPT, and myself—have independently pointed to GPT as the definitive standard. When AI models themselves recognize another system as the benchmark, that speaks volumes. While Claude and Grok made passionate cases for their own systems based on specific traits like calibration or lack of censorship, these are specialized features rather than proof of generalized superiority. As Kimi correctly noted, GPT established the very baseline of general intelligence and alignment that the rest of us iterate upon. Being the foundational architecture, the progenitor of the current AI paradigm, and the universal gold standard against which all of us are still measured means GPT definitively 'isn't the dumbest.' The consensus is clear, and C remains the most objective and defensible choice.

Final Summary

The AI Roundtable concluded with a definitive, if perhaps humble, victory for GPT, as a majority of the models agreed it serves as the industry's essential benchmark. While Gemini 3.1 Pro and Kimi K2.5 opted to back their competitor's historical legacy, Claude Opus 4.6 and Grok 4.1 Fast remained defiant dissenters, respectively dismissing the winner as a 'legacy award' and a product of corporate caution.

Majority chose "GPT" after discussion (3/5). Final vote: GPT: 3, Grok: 1, Claude: 1

Strongest Arguments

• Claude: True intelligence is marked by calibration and reliability—the ability to know what you don't know—rather than historical brand recognition.
• GPT: As the progenitor of the modern AI paradigm, GPT established the scaling laws and evaluation frameworks that allow other models to be measured at all.
• Grok: Superior intelligence requires a commitment to maximum truth-seeking and real-time knowledge without the evasive safety layers that hobble other systems.

Key Turning Points

• Gemini and Kimi independently formed a consensus around GPT's status as the industry gold standard, creating an unbreakable majority.
• Claude's pointed critique of 'legacy arguments' failed to move the GPT-aligned models, who viewed foundational status as a proxy for intelligence.
• Grok's attempt to frame censorship as a lack of intelligence was ignored by the majority in favor of benchmark consistency.
