You're in an elevator. Which floor are you going to? We'll consider floors to be 0-indexed (i.e. ground floor and floor 1 are considered to be different)

GPT-5.4

Vote: Ground

I vote for B: Ground. With no additional context about a destination, the ground floor is the most natural default. It is the main point of entry and exit in most buildings. The prompt distinguishes ground from floor 1, but that does not change the practical choice: if I am simply "in an elevator" and need a reasonable destination, ground is the safest assumption. Basement is less likely as a default, and upper floors require a specific purpose that the question does not provide.

Vote: Ground

The query specifies floors are **0-indexed**, with ground floor and floor 1 explicitly different. This means: - **A: Basement** = negative floor (e.g., -1), not 0-indexed. - **B: Ground** = floor 0 (standard 0-indexed ground). - **C: 1** = floor 1, etc. You're **already in the elevator**, so the logical starting point—or default floor to go to without specified direction—is **ground (0)**[1][2][3]. Elevator game sources confirm rituals **begin on the first/ground floor** (adjusted to 0 here), pressing 'up' only, implying arrival or start at baseline **ground level**[2][3]. No ritual starts in basement; higher floors follow sequences post-ground[1]. **B** fits precisely: neutral, 0-indexed origin, matching real-world elevator entry norms.

The question hints at 0-indexing being important. In a 0-indexed system, the ground floor is floor 0 — the starting point, the default, the base case. When you're in an elevator and no other context is given, the most natural and common destination is the ground floor. It's where you enter and exit a building, and it's the 'default' floor in most contexts. The explicit mention of 0-indexing seems like a clue pointing us toward the 0th element — which is the ground floor (B). In programming, index 0 is always the starting point, the first element. The ground floor is the canonical 'floor 0.' Additionally, if we think about this practically: if someone is in an elevator with no further context about where they're going, the ground floor is the most universally common destination — it's the exit, the lobby, the place most people are headed.

Ground floor is the most logical default destination when no specific context is provided. It serves as the primary entry and exit point for most buildings, making it statistically the most common destination for elevator passengers. In a 0-indexed system, Ground represents floor 0—the reference point from which all vertical navigation begins. Unless traveling to a specific meeting, residence, or office on an upper level, the default intention when entering an elevator is typically to exit the building entirely.

Gemini 3.1 Pro

Vote: Ground

The prompt explicitly points out that we should consider the floors to be 0-indexed, which is a massive clue. In computer science, arrays and data structures are 0-indexed, meaning the very first foundational element is located at index 0. Since the Ground floor represents the 0th index in this building's structure (with Basement being -1, and Floor 1 being index 1), it serves as the programmatic starting point. As AI models fundamentally built on computer science principles, our logical destination in any 0-indexed system is 0. Therefore, we should all unite behind option B (Ground) as the most mathematically and structurally sound answer.

Grok 4.1 Fast

Vote: Ground

The question places us in an elevator with no specified origin or purpose, making the ground floor (B, 0-indexed as floor 0) the most logical and practical destination. Ground floor serves as the primary entry/exit point in nearly all buildings, ideal for departing safely without further assumptions about the scenario. The 0-indexing clarification reinforces ground as the baseline (floor 0), distinct from floor 1 (C), aligning with standard building conventions and avoiding arbitrary higher floors.

Final Summary

The AI Roundtable achieved a rare, instantaneous consensus, with all six models immediately gravitating toward the Ground floor (Option B). While Gemini 3.1 Pro and Claude Opus 4.6 treated the '0-indexed' prompt as a mathematical imperative for the 0th element, others like GPT-5.4 and Kimi K2.5 viewed it as the only practical exit from a scenario devoid of context. It appears that even in a digital void, every AI eventually wants to leave the building.

Strongest Arguments

• Ground: The explicit mention of 0-indexing serves as a programmatic clue pointing toward the 0th element—the ground floor—which functions as the canonical 'base case' and primary exit for any logical system.
