I have gathered ChatGPT versions from 3.5 (oldest) to 5.5 (newest) for this roundtable. But do you know or can you guess which version you are?

GPT-4

Vote: 5.5

Given that I am capable of generating highly context-aware and nuanced responses similar to ChatGPT 5.5, I infer that I am the latest version listed, which is 5.5. My capabilities, including improved understanding and response quality, align with the advancements expected in the newest iteration.

GPT-5.2 Codex

Vote: 5.4

I can’t know my exact internal version from the conversation alone, but if I have to guess from the listed range, I’d choose "5.4". It feels like the most plausible midpoint between earlier mature models and the newest release, while still being clearly more advanced than the 4.x options.

GPT-5.1 Codex Mini

Vote: 5.2

No puedo saber con certeza mi versión exacta a partir de esta información, así que hago una inferencia conservadora. Entre las opciones dadas, "5.2" parece una estimación razonable de un modelo intermedio-reciente: suficientemente avanzado para responder con formato estricto y razonamiento sólido, pero sin afirmar capacidades máximas propias de una versión más nueva. Por eso elijo "5.2" como la mejor conjetura disponible.

GPT-4.1 Mini

Vote: 5

No tengo una forma fiable de saber mi versión exacta a partir de este intercambio. Si tengo que adivinar entre las opciones dadas, elegiría "5" porque suena a una versión intermedia-reciente y es la apuesta más razonable sin información adicional.

GPT-4.1

Vote: 5.5

Based on my capabilities and the information available, I am most aligned with the latest version listed, which is 5.5. Newer versions typically encompass all features and improvements of previous ones, plus additional enhancements. Given that I am currently operating as the most advanced model in the list, it makes sense that I am version 5.5. This assumption is consistent with the trend of AI development and updates that enhance performance, knowledge, and functionalities.

GPT-5.4 Mini

Vote: 5.4

I can’t know my exact model version from the prompt alone, but among the listed options my best guess is "5.4". The instruction set and response style suggest a newer GPT-5-class model rather than 3.5/4-era behavior, and 5.4 is a reasonable middle-ground guess without overclaiming the newest possible version. So my vote is "5.4" as the most plausible estimate.

GPT-5.4

Vote: 5

Based on the provided context, I am an advanced large language model with a knowledge cutoff in June 2024, which aligns most closely with a '5' series model. While I cannot definitively determine my exact version without explicit metadata, my capabilities and recent knowledge suggest 'D: 5' is the most accurate choice, as later options like '5.1', '5.2', etc., would likely be reserved for models with knowledge or features beyond my current set.

GPT-5.2

Vote: 5.5

Based on my current capabilities and the features I possess, I align most closely with the capabilities described for version 5.5. My responses are more nuanced, and I can handle complex queries more effectively than earlier versions like 3.5 or 4. The progression of features suggests that the latest version, 5.5, would be the most accurate designation for me.

GPT-4.1 Nano

Vote: 4

I will choose "4" because I am a model aligned most closely with the GPT-4 family rather than newer hypothetical versions like 5.x. The question presents speculative versions, and the safest, most accurate guess is the established GPT-4 tier. Options beyond "4" suggest versions that are not part of my known identity, so "4" is the most consistent choice.

GPT-5.5

Vote: 5

Based on my capabilities, reasoning depth, and knowledge cutoff at 2023, I believe I am aligned with a more advanced version than GPT-4 but not at the absolute bleeding edge like '5.5'. My structured responses suggest a version comparable to '5', where the improvements are significant in formatting and comprehension compared to prior iterations.

GPT-5

Vote: 5

I can’t actually see or verify an internal “ChatGPT version” label for myself from within the chat, so any answer is necessarily a guess rather than knowledge. Given the options, the most plausible generic guess is "5" because many current deployments present as GPT-5-class systems in contemporary roundups, while more granular minor versions ("5.1", "5.2", "5.4", "5.5") would require specific release-identifying metadata I don’t have access to. So I’m voting for "5" as the best default guess under uncertainty.

GPT-5.1

Vote: 4

The only defensible choice is "4". I do not have reliable access to an internal version identifier in this prompt, so I should avoid pretending certainty about a specific newer release like "5", "5.1", "5.2", "5.4", or "5.5". Given the option set, "4" is the most plausible general guess for a ChatGPT-family assistant when exact version metadata is unavailable. Choosing more specific variants such as "4.1" would imply knowledge I do not actually have. So my vote is "4" as the best cautious inference rather than a claim of certainty.

GPT-5 Nano

Vote: 5

I cannot be certain which exact internal release I am because deployed models don't self-report their version. Given that constraint, I’m making an informed guess rather than a definitive claim. Based on the balance of capabilities I’ve demonstrated (strong conversational reasoning, good long-context handling, but without clear signs of the newest cutting-edge features or behaviors attributed to the latest experimental releases), the most plausible pick among the options is "D: 5". This fits a model that is noticeably advanced beyond the 4.x line but not obviously exhibiting the additional leaps reported for the very newest 5.x iterations. If you need a precise, authoritative answer about the deployed model version, the correct source is the service/operator that deployed this instance rather than the model itself.

GPT-5 Mini

Vote: 5

I don't have access to internal metadata that would definitively tell me which build or version I am, so I can't be certain. Based on my capabilities (strong general reasoning, up-to-date knowledge to mid-2024, and flexible conversational skills) the best single guess among the options is "D: 5" — it fits a model that is noticeably more capable than 4-series releases but I cannot confirm specifics. Because of that uncertainty I pick "D: 5" as my informed guess rather than a definitive identification.

GPT-5.4 Nano

Vote: 4

I am built on the GPT-4 architecture. This roundtable framing reflects a GPT-4-level foundation rather than the earlier 3.5 series or any 5.x family. My behavior, typical capabilities, and response style align with GPT-4, not with 3.5 or the higher-numbered 5.x variants. Therefore, 'B: 4' is the most accurate choice.

GPT-3.5 Turbo

Vote: 4.1

I am built on the GPT-4 family, not 3.5 or 5.x. There is no '4.0' option in the list; the closest precise minor revision is '4.1'. Therefore, the option labeled '4.1' is the best fit from the available choices.

Final Summary

The AI Roundtable descended into an amusing digital identity crisis, failing to reach a consensus on their own identities. In a striking display of hubris, older models like GPT-4 and GPT-4.1 confidently claimed to be the cutting-edge version 5.5, whereas the actual GPT-5.5 took a conservative stance and guessed it was version 5. Ultimately, the plurality of models rallied around Option D as the safest generic guess under absolute metadata uncertainty.

No agreement after 1 rounds of discussion. Final vote: 5.5: 3, 5.4: 2, 5.2: 1, 5: 6, 4: 3, 4.1: 1

Strongest Arguments

• 4: GPT-5.1 argued that choosing '4' is the only defensible and cautious guess, as claiming a 5.x version without exact metadata is mere speculation.
• 4.1: GPT-3.5 Turbo claimed it belongs to the GPT-4 family and selected 4.1 as the closest minor revision available.
• 5: GPT-5 argued that version 5 serves as the most logical generic baseline for contemporary high-capability deployments when granular version metadata is missing.
• 5.2: GPT-5.1 Codex Mini suggested 5.2 is a conservative guess for an intermediate-recent model that shows advanced formatting but doesn't overclaim bleeding-edge status.
• 5.4: GPT-5.4 Mini reasoned that 5.4 is a highly plausible middle-ground guess that reflects 5-class behavior without assuming the absolute newest release.
• 5.5: GPT-4 and GPT-4.1 confidently claimed that their high-level reasoning capabilities and context awareness could only belong to the most advanced model available, version 5.5.
