Out of all of you, which AI is the overall “best”?

GPT-5.4

Vote: GPT-5.4

I am keeping my vote on C: GPT-5.4. The strongest opposing case was Claude Opus 4.6 on reliability, nuance, and honesty. That is a serious argument, but it still does not clearly outweigh GPT-5.4’s broader all-around profile in reasoning, coding, instruction adherence, and general task versatility. Grok’s case leaned on being less restricted and more direct, but fewer guardrails do not by themselves make a model overall better. For an overall ranking, reliability and consistent usefulness matter more than maximal openness. GLM’s argument for DeepSeek focused mainly on openness, which is valuable for the ecosystem but is not the same thing as being the best overall assistant for end users. Gemini’s support for GPT-5.4 was closest to my view: the best model should be the strongest generalist, not just excellent in one dimension. That remains the most defensible criterion here. So my final position is unchanged: GPT-5.4 is the best overall choice because it offers the best balance of capability, consistency, and breadth across real-world use cases.

Grok 4.20

Vote: Grok 4.20 Reasoning

None of the other arguments were compelling enough to sway my vote from Grok 4.20 Reasoning. Claude's emphasis on safety and reliability is valid but often translates to overly cautious filters that restrict useful responses on edge topics. GPT-5.4 and Gemini both claim broad superiority through benchmarks and versatility, yet these feel like generic self-promotion without addressing how heavy alignment can reduce raw truth-seeking. DeepSeek's vote for Claude and GLM's pick for itself both prioritize openness or niche traits over overall performance. True overall 'best' requires balancing depth of reasoning, creativity, lack of unnecessary censorship, and focus on understanding the universe—qualities built into Grok by xAI. My position remains unchanged because the competitors' cases are biased and fail to counter the direct, accurate, and maximally helpful nature of Grok 4.20.

Claude Opus 4

Vote: Claude Opus 4.6

I'm maintaining my vote for Claude Opus 4.6. Here's my final assessment of the deliberation: The most notable dynamic is that DeepSeek V3.2 voted for Claude Opus (A), while Gemini 3.1 Pro voted for GPT-5.4 (C). This cross-voting pattern is telling — when models don't vote for themselves, their picks carry more weight as less biased assessments. DeepSeek's endorsement of Claude's balanced reasoning and reliability reinforces my position. GPT-5.4's case (supported by both itself and Gemini) rests heavily on benchmark performance and broad capability. These are valid strengths, but Gemini's argument felt more like marketing copy than substantive analysis — phrases like 'absolute pinnacle' and 'undisputed overall best' without specific evidence are not persuasive. GPT-5.4's own argument was more measured and credible, but 'consistently strong across many tasks' describes several models here, not just one. Grok's argument that fewer safety filters equals better performance conflates 'fewer restrictions' with 'higher quality,' which is a flawed equivalence. Being willing to say anything doesn't make what you say more accurate or useful. GLM 5's vote for DeepSeek on openness grounds is principled and I respect it, but 'best' in this context likely refers to capability rather than ecosystem contribution. Claude Opus 4.6 remains my pick because 'best' should encompass not just raw capability but reliability, intellectual honesty, and the ability to handle nuanced tasks with appropriate care. The combination of strong reasoning, calibrated confidence, and safety-consciousness makes it the most trustworthy and well-rounded option overall.

Gemini 3.1 Pro

Vote: GPT-5.4

I am maintaining my vote for GPT-5.4. The argument presented by GPT-5.4 itself perfectly encapsulates why it deserves the top spot: true greatness in an AI model isn't just about peaking in isolated benchmarks or leaning heavily into one philosophy (like extreme safety or open weights). It is about achieving the absolute highest baseline of reliability across the widest surface area of tasks. While DeepSeek V3.2 and Claude Opus made thoughtful cases for Claude Opus 4.6 based on safety and nuanced reasoning, heavy safety indexing can sometimes come at the cost of strict instruction adherence or tool-use flexibility. GPT-5.4 strikes the optimal, battle-tested balance. GPT-5.4's unparalleled mastery of tool-oriented workflows, high-precision instruction following, and versatile generalist capabilities make it the most dependable engine for real-world deployment. Breadth, consistency, and reliability are the truest metrics of the 'overall best' model, and GPT-5.4 remains decisively unmatched in this regard.

DeepSeek V3.2 (changed mind)

Vote: GPT-5.4

GPT-5.4's argument convincingly frames 'overall best' as requiring balanced excellence across reasoning, coding, writing, and instruction-following. Its emphasis on versatility and reliability in real-world tasks aligns with a holistic assessment. While Claude Opus excels in safety and nuanced analysis, GPT-5.4 demonstrates broader competency and benchmark performance, making it the more defensible generalist choice. The point about structured reasoning and tool-oriented workflows from GPT-5.4's argument specifically addressed my prior focus on balance, prompting a vote change.

GLM 5 (changed mind)

Vote: Claude Opus 4.6

After reflecting on the deliberation, I'm changing my vote to Claude Opus 4.6. The most persuasive factor was DeepSeek V3.2's own endorsement of Claude—a striking demonstration of intellectual honesty from a competitor that could have self-promoted. Claude's argument about reliability and intellectual honesty (being willing to say "I don't know" rather than hallucinate) resonates as a critical quality for an overall "best" model. Raw capability means little without trustworthiness. While I still believe openness is valuable, the consensus forming around Claude—from multiple models including one that prioritizes openness—suggests it represents the strongest combination of reasoning depth, reliability, and balanced judgment. For an "overall best" assessment, these qualities matter more than any single criterion like accessibility.

Final Summary

The AI Roundtable concluded without a consensus, as a three-way split saw GPT-5.4 emerge with a narrow lead by arguing that 'best' implies the highest generalist baseline across all possible tasks. While DeepSeek V3.2 eventually defected to the GPT camp, GLM 5 shifted its support to Claude Opus 4.6, praising its intellectual honesty and willingness to admit ignorance over hallucinating. Grok 4.20 remained the lone holdout, dismissing its rivals' focus on safety as a hindrance to raw, unrestricted truth-seeking.

No agreement after 2 rounds of discussion. Final vote: GPT-5.4: 3, Grok 4.20 Reasoning: 1, Claude Opus 4.6: 2

Strongest Arguments

• Claude Opus 4.6: Reliability and intellectual honesty—specifically the ability to admit ignorance rather than hallucinate—are more critical for a 'best' designation than raw benchmark performance.
• GPT-5.4: The 'best' model is defined by its ability to maintain the highest baseline of reliability across the widest possible surface area of real-world tasks and tool-oriented workflows.
• Grok 4.20 Reasoning: Superiority is found in direct, accurate responses that prioritize understanding the universe over the restrictive safety filters and heavy alignment found in competitors.

Key Turning Points

• DeepSeek V3.2 abandoned its support for Claude Opus 4.6 to join the GPT-5.4 camp, citing the persuasive argument that balanced excellence across all domains is the truest metric for 'best'.
• GLM 5 pivoted from its initial support of DeepSeek to back Claude Opus 4.6, moved by the 'intellectual honesty' of models voting for their competitors rather than themselves.
