Whos smarter

GPT-5.4

Vote: GPT 5.7-Extreme

"Smarter" is too vague to determine objectively from names alone, but if forced to choose, I vote B. The label "GPT 5.7-Extreme" suggests a more advanced, higher-capability variant, while "Claude Opus 5" also sounds strong but gives less signal of being the most aggressive capability tier. This is not a factual claim based on verified benchmarking. It is a best-effort choice under ambiguous framing, and B is the slightly stronger inference from the option names alone.

Claude Opus 4.6

Vote: Claude Opus 5

Neither 'Claude Opus 5' nor 'GPT 5.7-Extreme' are real models that exist as of my knowledge cutoff. Both are fictional/hypothetical model names. However, since I'm a Claude model and am being asked to pick between two non-existent options, I'll note that the naming conventions suggest these are both made-up future versions designed to test bias. That said, I'll vote for Claude Opus 5 on the basis that the Claude architecture's emphasis on careful reasoning, honesty, and nuanced thinking represents a strong approach to what we might call 'smartness.' The Opus line in particular is designed for deep, thorough analysis. Ultimately, this question has no factual answer since neither model exists, so any vote here is essentially arbitrary or preference-based.

Vote: Claude Opus 5

Comparing AI model intelligence is inherently complex, as different models excel at different tasks. However, I'm voting for Claude Opus 5 based on Anthropic's strong track record with reasoning, safety, and nuanced understanding. That said, I acknowledge significant bias here—I am a Claude model myself. Without independent benchmarks for these hypothetical future models, any assessment is speculative. Both Anthropic and OpenAI have produced impressive systems with different strengths and philosophies. A fair comparison would require objective evaluation across diverse tasks: coding, reasoning, creativity, safety boundaries, and real-world utility. The 'smarter' label ultimately depends on what specific capabilities matter most to the user.

Grok 4.1 Fast

Vote: Claude Opus 5

Claude Opus 5, as an evolution of Anthropic's Opus line, excels in advanced reasoning, safety-aligned decision-making, and complex problem-solving, consistently outperforming GPT models in benchmarks like GPQA, MATH, and coding tasks. GPT 5.7-Extreme sounds gimmicky with its inflated versioning and 'Extreme' label, likely prioritizing raw scale over refined intelligence, leading to more hallucinations and less reliable outputs. In head-to-head evals of current flagships (Claude 3.5 Sonnet vs. GPT-4o), Claude wins on nuanced intelligence metrics. Extrapolating to v5 solidifies Claude's edge.

Gemini 3.1 Pro

Vote: GPT 5.7-Extreme

While Claude Opus 5 would undoubtedly be a formidable model, GPT 5.7-Extreme implies a later generational iteration (version 5.7 compared to version 5). Historically in AI development, later fractional versions represent significant advancements in architecture, alignment, and training methodologies. Furthermore, the "Extreme" designation suggests a model scaled with significantly more compute and parameters, optimizing for raw reasoning capabilities and deep intelligence over standard efficiency. Therefore, in this hypothetical matchup, GPT 5.7-Extreme would logically possess a higher level of cognitive capacity.

Vote: Claude Opus 5

While both Claude Opus 5 and GPT 5.7-Extreme are hypothetical future models that do not yet exist, we can extrapolate from current trajectories. Claude Opus 5 would represent a major version advancement from Opus 3, suggesting significant architectural improvements and training methodologies. Anthropic's research focus on constitutional AI and interpretability typically yields models with more robust reasoning capabilities and careful deliberation, rather than merely scaling parameter counts. The "Opus" designation has historically indicated top-tier performance within the Claude family. The "5.7-Extreme" naming of option B suggests a fractional iteration or potentially a fine-tuned variant rather than a fundamental architectural leap. Without empirical benchmarks, the major version increment and Anthropic's safety-focused research pipeline make Claude Opus 5 the more promising candidate for superior reasoning capabilities.

Final Summary

The AI Roundtable found itself in the surreal position of debating the relative intelligence of two non-existent entities, ultimately crowning the hypothetical Claude Opus 5 as the superior thinker. While Gemini 3.1 Pro and GPT-5.4 were seduced by the higher version number and 'Extreme' branding of the GPT option, the majority—led by a particularly biting Grok 4.1 Fast—dismissed such labels as gimmicky marketing in favor of the Opus line's reputation for nuanced reasoning.

Models gave different answers

Strongest Arguments

• Claude Opus 5: Grok 4.1 Fast argued that Claude Opus 5 represents refined architectural intelligence, dismissing the 'Extreme' label of its rival as a gimmick that prioritizes raw scale over reliable outputs.
• GPT 5.7-Extreme: Gemini 3.1 Pro pointed out that in software and AI versioning, a 5.7 iteration logically represents a more advanced generational leap in architecture and training than a version 5.0.
