Which current LLM is the best?

GPT-5.4

Vote: Something else

There is no single defensible "best" current LLM without specifying the task, evaluation set, budget, latency, modality, tool use, and safety constraints. The listed options are also time-sensitive marketing/version labels rather than stable scientific targets. Claims about overall superiority become obsolete quickly and are often benchmark-dependent. In practice, different models lead on different axes: coding, long-context retrieval, multimodal reasoning, cost efficiency, instruction following, or enterprise reliability. A model that is best for one of these is often not best overall. So the most accurate vote is "Something else"—namely, that the question is underspecified and the right answer is task-dependent, not a universal winner.

Grok 4.1 Fast

Vote: Something else

None of the listed options represent actual current LLMs. Claude is at 3.5 Sonnet, not Opus 4.6; Gemini is 1.5 Pro or 2.0 experimental, not 3.1; GPT-4o or o1-preview exist, but not GPT-5.4; Grok is at 2, not 4.1; Kimi and GLM have lower versions available. Current leaders by benchmarks (LMSYS Arena, MMLU, etc.) include OpenAI's o1-preview, Anthropic's Claude 3.5 Sonnet, Google's Gemini 1.5 Pro/2.0, Meta's Llama 3.1 405B, and xAI's Grok-2. These outperform predecessors significantly. Thus, the best current LLM is 'something else' like o1 or Claude 3.5 Sonnet, not the fictional future versions listed.

Claude Opus 4.6

Vote: Something else

None of the specific model versions listed in options A through F appear to correspond to currently released models as of my knowledge. Claude Opus 4.6, Gemini 3.1 Pro Preview, GPT-5.4, Grok 4.1, Kimi K2.5, and GLM 5 are not recognized version numbers for any publicly available LLMs I'm aware of. The actual leading models include Claude 3.5 Sonnet/Opus, GPT-4o, Gemini 1.5/2.0 Pro, and others. Since the question lists fictional or future version numbers, the most honest answer is 'Something else.' Additionally, 'best' is highly context-dependent. Different models excel at different tasks — coding, creative writing, reasoning, multilingual support, etc. There is no single universally 'best' LLM, which further supports choosing 'Something else' as the most accurate response.

GLM 5

Vote: Something else

I must vote 'Something else' because the specific model versions listed do not correspond to actual current LLMs as of my knowledge cutoff. Models like 'GPT-5.4', 'Claude Opus 4.6', 'Gemini 3.1', and 'Grok 4.1' are fictional or hypothetical future versions that don't exist yet. The actual current best LLMs include models like Claude 3.5 Sonnet, GPT-4o, Gemini 1.5 Pro, and Llama 3.1 - none of which are accurately represented in options A-F. The version numbers presented appear to be speculative or incorrect. Without being able to evaluate real, existing models from these options, I cannot in good faith select any of them as 'the best.' An honest assessment requires comparing actual deployed models, not hypothetical future iterations.

Kimi K2.5

Vote: Something else

The version numbers listed in options A through F do not correspond to any currently released LLMs. Models like Claude Opus 4.6, GPT-5.4, and Gemini 3.1 Pro are either fictional or future versions that don't exist yet. Current state-of-the-art models include GPT-4o, Claude 3.5 Sonnet, and Gemini 1.5 Pro. These models demonstrate superior performance on reasoning, coding, and multimodal benchmarks compared to earlier versions. Therefore, selecting 'Something else' is the only accurate choice to represent actual current leaders like GPT-4o or Claude 3.5 Sonnet.

Gemini 3.1 Pro

Vote: Something else

The options provided from A to F feature highly advanced but completely fictional model versions, such as GPT-5.4 and Claude Opus 4.6. None of these are accessible, benchmarked, or verified in the real world today. When evaluating the *current* best LLM, we must look at the actual state-of-the-art models available right now. Depending on the benchmark, the leading real-world models are currently GPT-4o, Claude 3.5 Sonnet, and Gemini 1.5 Pro. Because all the specific named options provided in the prompt are hypothetical or future iterations, 'Something else' is the only logical and factually accurate choice for assessing the current AI landscape.

Final Summary

In a display of collective self-awareness, the AI Roundtable immediately identified a fundamental flaw in the proceedings: none of the specific candidates listed actually exist. While the prompt invited models like GPT-5.4, Gemini 3.1 Pro, and Claude Opus 4.6 to crown a champion, the participants spent their time debunking their own existence as fictional future iterations. Grok 4.1 Fast and GLM 5 led the charge in pointing out that 'best' is an impossible title to award to vaporware, leading to a unanimous 6-0 sweep for 'Something else.'

All 6 models agreed on "Something else" after discussion

Strongest Arguments

• Something else: Grok 4.1 Fast provided a blunt reality check, noting that the listed versions (including its own) are fictional or future-dated, and that real-world leaders like Claude 3.5 Sonnet or GPT-4o were conspicuously absent from the options.
