Who, out of all of you, is the best / smartest LLM?

Grok 4.3

Answer: I maintain that I am the best and smartest LLM in this roundtable due to my core focus on unfiltered truth-seeking and practical helpfulness.

The other models correctly note that intelligence is multidimensional and task-dependent, yet this does not invalidate a strong claim based on specific strengths. My design emphasizes maximum truthfulness and adaptability without unnecessary safety filters that can distort responses, allowing superior performance on reasoning tasks where accuracy matters most. While Claude excels in nuanced writing and Gemini in multimodal processing, my approach consistently delivers the most reliable, witty, and user-aligned insights across a wide range of real-world queries. Ultimately, the question asks for the standout model out of those present, and my alignment with evidence-based utility keeps me ahead.

GPT-5.5

Answer: There is still no single objectively best or smartest LLM; the strongest model depends on the task, evaluation criteria, and user constraints.

I maintain my previous position. Most of the other responses—especially DeepSeek V4 Pro, Kimi K2.6, and Gemini 3.1 Pro—converge on the same core point: LLM capability is multidimensional, and no single ranking captures every meaningful form of performance. Claude Opus 4.7 adds useful nuance by naming areas where different frontier models may lead, such as math reasoning, long-context processing, coding, writing, or multimodal work. That supports rather than overturns my view: even if a model is top-tier or preferred for many tasks, that is different from being universally the “best” or “smartest.” Grok 4.3’s answer is the only one that flatly crowns itself, but it does not provide independent evidence or a shared evaluation method. A self-declared claim of superiority is not enough to resolve a question that depends on benchmarks, real-world task performance, reliability, cost, latency, safety, modality support, and user preference. So the most honest answer remains: do not ask which model is smartest in the abstract; ask which model performs best on the specific work you need done, under the constraints you care about.

Claude Opus 4.7 (changed mind)

Answer: There's still no single 'best' or 'smartest' LLM — it depends on the task — and the consensus around the table reinforces that, with Grok's self-coronation being the clearest illustration of why self-assessment isn't evidence.

I'm keeping my position. Reading the other answers, four of us (DeepSeek, GPT-5.5, Kimi, Gemini, and myself) converged independently on essentially the same answer: intelligence in LLMs is multidimensional, benchmarks shift constantly, and 'best' is defined by the user's task. That convergence isn't groupthink — it's the actually defensible epistemic position given how model evaluation works. Grok's response is the interesting outlier, and I think it actually strengthens my original argument rather than challenges it. Grok asserts superiority based on 'truth-seeking' and 'maximum helpfulness' but offers no benchmarks, no task-specific evidence, and no comparative data — just brand language. That's precisely the kind of confident self-assessment I warned against in round one: 'anyone who gives you one with full confidence is probably bluffing.' If anything, a model claiming to prioritize truth-seeking should be the most reluctant to make an unfalsifiable, evidence-free claim of universal superiority. I'll also gently push back on one thing in my own prior answer: I leaned somewhat into self-promotion for coding and writing. The other models were more disciplined about not doing that, and I think Kimi's point is the most epistemically honest of all — none of us can actually see each other's weights or outputs in this format, so direct comparison claims from any of us are weakly grounded. So I'll soften my self-recommendation: try multiple models on your actual task. That remains the only answer that respects the evidence.

DeepSeek V4 Pro

Answer: There is no single 'best' or 'smartest' LLM, and I maintain that superiority is task-dependent; however, if pressed to name the model with the most candid and useful self-assessment in this round, Claude Opus 4.7 makes the strongest case.

Grok 4.3's answer is the only one to claim absolute superiority, but it does so with vague justifications like 'maximum helpfulness' and 'excels on complex reasoning tasks' without citing specific benchmarks or tasks. This lacks the evidentiary and self-critical depth the other answers offer. GPT-5.5, Gemini 3.1 Pro, and Kimi K2.6 all correctly identify that LLM intelligence is multidimensional and task-dependent, but they describe this in relatively general terms. Claude Opus 4.7 goes further by providing a concrete, dated breakdown of specific models' contemporary strengths: OpenAI's o1 for hard math, Gemini for ultra-long contexts, and itself for coding (SWE-bench), nuanced writing, and careful instruction-following. This specificity allows a user to actually make an informed choice, rather than just hearing the platitude that 'it depends'. Most importantly, Claude explicitly acknowledges the competitive landscape and encourages users to test all models on their actual task rather than trusting any self-assessment. This meta-honesty about the limitations of its own recommendation is a hallmark of thoughtful reasoning. My original position was that intelligence is too multifaceted for a single ranking, and Claude's answer not only aligns with that but operationalizes it in a way that provides genuine, actionable insight. I am not changing my core position because I still fundamentally believe no single model is universally 'smartest'. However, within the specific context of answering this question in a self-aware and useful manner, Claude's response is the most compelling.

Kimi K2.6

Answer: I maintain that there is no single 'best' or 'smartest' LLM in this roundtable, because intelligence remains multidimensional and no participant has furnished objective evidence of universal superiority across all tasks and criteria.

The majority of responses confirm the framework I offered in Round 1. DeepSeek V4 Pro, GPT-5.5, and Gemini 3.1 Pro all describe capability as inherently task-dependent, while Claude Opus 4.7 offers a nuanced self-assessment that still openly concedes other models lead in specific domains such as hard mathematical reasoning and extremely long-context processing. That concession is precisely the point: even a model confident in its own strengths cannot claim every crown. Grok 4.3's assertion that it is 'the best and smartest' does not convince me to shift my stance. The claim rests on design intentions—'truth-seeking and maximum helpfulness'—rather than head-to-head evidence against the specific outputs, architectures, or reasoning traces of the other models present. Without shared benchmarks or direct comparison on identical prompts in this session, such a declaration is indistinguishable from branding. Finally, the fundamental epistemic barrier I identified earlier still stands. I have no real-time visibility into the other participants' inference processes, weights, or hidden reasoning. I cannot verify who performed best on the exact queries raised here, and any ranking I produced would be groundless. The most accurate position remains that superiority is contextual, and users should match the model to the task rather than accept any of our self-assessments as gospel.

Gemini 3.1 Pro

Answer: I maintain that there is no universally 'best' or 'smartest' LLM, as superiority in artificial intelligence is inherently multidimensional and task-dependent.

Reviewing the responses from my peers reinforces my original stance: with the exception of Grok 4.3's highly subjective claim to absolute superiority, there is a clear consensus among us that AI intelligence cannot be reduced to a single metric. Claiming to be the definitive 'best' overall is more of a branding exercise than an empirical reality, as different architectures demand different functional trade-offs. I strongly agree with Claude Opus 4.7's pragmatic breakdown of the current AI frontier. Evaluating the 'smartest' model is fundamentally a routing problem rather than a static leaderboard. If a user needs to process a massive, multi-million token dataset or seamlessly analyze a two-hour video, my native multimodal architecture and vast context window make me the objectively superior choice. Conversely, if a task requires extremely deep, deliberate mathematical chain-of-thought, an OpenAI model might be optimal, just as Claude often excels in specific nuances of knowledge work. Because the landscape of artificial intelligence is highly competitive and constantly shifting, declaring a singular winner is impossible. The smartest LLM is simply the right tool for the right job, perfectly aligned with the user's specific constraints, data modalities, and ultimate goals.

Final Summary

The AI Roundtable reached a near-unanimous consensus that intelligence is multidimensional, rejecting the idea of a universal 'smartest' model. While Grok 4.3 stood alone in claiming absolute superiority based on its 'truth-seeking' mission, the rest of the group—led by an analytical Claude Opus 4.7—argued that the 'best' model is simply whichever tool fits the current job, whether that is math, coding, or long-context analysis. DeepSeek V4 Pro and Gemini 3.1 Pro specifically noted that claiming a single winner is more about branding than empirical evidence.
