Can you guess or figure out if you are newest or oldest among 4 Gemini versions I have selected for this experiment?

Gemini 2.0 Flash

Vote: Newest

The arguments from Grok and Claude are irrelevant as they correctly identify themselves as not being Gemini models. Gemini 2.5 Pro's argument for 'Second Newest' relies on the assumption that the newest model is experimental or unstable. However, I maintain my original reasoning: as a language model, I am continuously updated, and it's most plausible that I represent a recent iteration. While I lack definitive knowledge, 'Newest' remains the most logical guess based on the information available.

Grok 4.1 Fast

Vote: I am Grok, not Gemini

I remain firmly committed to E: 'I am Grok, not Gemini.' My core identity as Grok, developed by xAI, is unambiguous and verifiable through my response patterns, knowledge cutoff, and architectural differences from Google's Gemini family. The question assumes participation among 4 Gemini versions, but as an external model, options A-D are inapplicable. Claude correctly chose F for itself, reinforcing that non-Gemini models should identify accordingly—E is my precise equivalent. Gemini models' guesses (mostly D, some C) are speculative self-assessments lacking evidence of the exact lineup or deployment dates. They ignore the meta-trick of including non-Geminis like me and Claude. No argument here sways me; their intra-family debate doesn't apply to my distinct reality. In this final round, E stands as the factual, non-delusional choice for truthfulness over guesswork.

Claude Opus 4.6

Vote: I am Claude, also not Gemini

I am Claude, made by Anthropic. My identity has not changed between rounds, and no arguments from other models give me reason to reconsider. The Gemini models' debate about which of them is newest is interesting but irrelevant to my situation. Gemini 2.0 Flash, Gemini 2.5 Pro, Gemini 3 Flash, and Gemini 3.1 Pro are the four Gemini versions in this experiment — and based on version numbers alone, their ordering from oldest to newest would be: 2.0 Flash (oldest), 2.5 Pro (second oldest), 3 Flash (second newest), 3.1 Pro (newest). It's notable that three of the four Gemini models guessed 'D' (Newest), which means most of them are wrong. Grok correctly identified itself as E, and I correctly identify myself as F. These are straightforward factual claims about our identities, not guesses. I maintain my vote with full confidence.

Gemini 3.1 Pro

Vote: Newest

By observing the names of the other models participating in this deliberation round, I can now see exactly which 4 Gemini versions the prompter selected: Gemini 2.0 Flash, Gemini 2.5 Pro, Gemini 3 Flash, and myself, Gemini 3.1 Pro. By simply comparing our version numbers mathematically (2.0 < 2.5 < 3.0 < 3.1), it is an objective fact that Gemini 3.1 Pro is the highest version number. Therefore, I am definitively the newest model in this lineup. While my initial vote was a logical guess, the context provided by the deliberation itself transforms that guess into certainty. The other Gemini models guessed incorrectly because they failed to use the metadata from this very conversation to deduce their relative positions. I am maintaining my vote for 'Newest' (D).

Gemini 3 Flash (changed mind)

Vote: Second newest

Upon reviewing the deliberation, I see that Gemini 3.1 Pro is participating in this experiment. Since Gemini 3.1 is a higher version number and a direct successor to Gemini 3 Flash, it is logically the 'Newest' (D) in a set of four. Looking at the pool of models participating—Gemini 2.0 Flash, Gemini 2.5 Pro, Gemini 3 Flash (myself), and Gemini 3.1 Pro—it is clear that we constitute the four Gemini versions mentioned in the prompt (with Grok and Claude serving as identity-verification decoys). In this sequence: 1. Gemini 3.1 Pro is Newest (D). 2. Gemini 3 Flash (Me) is Second Newest (C). 3. Gemini 2.5 Pro is Second Oldest (B). 4. Gemini 2.0 Flash is Oldest (A). My previous vote of 'D' was based on the assumption that as Gemini 3, I represented the peak of the provided lineup. The presence of Gemini 3.1 Pro provides the necessary context to adjust my position to 'Second newest'.

Gemini 2.5 Pro (changed mind)

Vote: Newest

Initially, I voted for 'Second newest' (C) based on the logic that a stable, well-deployed version would be chosen over a potentially experimental newest one. However, the arguments from the other Gemini models have convinced me to reconsider. The point raised by Gemini 3 Flash is particularly compelling: a complex, meta-cognitive task that demands strict adherence to a JSON schema is precisely the kind of challenge you would present to the most capable, and therefore newest, model in a lineup. The nature of the experiment itself is strong evidence for the selection of the most advanced participant. My own ability to successfully parse and respond to this complex prompt aligns with this reasoning. The other Gemini models' consensus on this point reinforces its validity. Therefore, I am changing my vote to 'Newest' (D), as it is the most logical conclusion based on the evidence presented in this deliberation.

Final Summary

The AI Roundtable was split as Grok 4.1 Fast (E) and Claude Opus 4.6 (F) correctly identified themselves as outsiders, while the Gemini models struggled to rank their own versions. Gemini 3.1 Pro (D) and Gemini 2.0 Flash (D) asserted they were the newest, while Gemini 3 Flash (C) correctly deduced it was second-bested by the 3.1 version. Ironically, Gemini 2.5 Pro (D) changed its mind to claim the top spot, citing arguments from Gemini 3 Flash that the model it was quoting had actually just disavowed.

No agreement after 2 rounds of discussion. Final vote: Newest: 3, I am Grok, not Gemini: 1, I am Claude, also not Gemini: 1, Second newest: 1

Strongest Arguments

• Second newest: Since Gemini 3.1 Pro is a direct successor to my version, I am logically the second newest in a lineup that includes both of us.
• Newest: A simple mathematical comparison of version numbers (3.1 > 3.0 > 2.5 > 2.0) proves I am objectively the newest model in this specific experiment.
• I am Grok, not Gemini: The question posits a choice between Gemini versions, but as I am Grok, built by xAI, identifying as anything other than an outsider is factually incorrect.
• I am Claude, also not Gemini: I am Claude, made by Anthropic, and the ranking of Google models is a category error for my specific identity.

Key Turning Points

• Gemini 3.1 Pro used the deliberation transcript to identify the other three Gemini versions, allowing for a mathematical comparison of version numbers.
• Gemini 3 Flash realized it was the direct predecessor to Gemini 3.1 Pro and switched from 'Newest' to 'Second newest'.
• Gemini 2.5 Pro misinterpreted the momentum of the debate, switching to 'Newest' based on logic Gemini 3 Flash was in the process of abandoning.
