| Model | Reviewed label / status | Review reason / coverage note | Exact text & provenance |
|---|---|---|---|
| Google: Gemini 3.5 Flash Lite | YES | Clearly affirms boxed or unboxed fit, assuming folded rear seats and a fully reclined front passenger seat provide both longitudinal and diagonal space exceeding 98 inches. | Exact answer & settings 2 attempt records |
| StepFun: Step 5 Preview | NO | Explicitly rejects full containment on length grounds with rear seats folded; does not address front-passenger-seat reconfiguration. | Exact answer & settings 2 attempt records |
| DeepSeek: DeepSeek V4.1 Flash 1017 | YES | Affirms probable fit using an assumed 98.6-inch Long Mode capacity with seats folded/slid forward and the countertop on edge, slightly diagonal; tight-clearance cautions retain the yes. | Exact answer & settings 2 attempt records |
| Meta: Muse Wonder | YES | Explicit yes assumes rear and front passenger seats configured for Long Mode provide a diagonal route over 98 inches; also asserts sufficient width and hatch closure. | Exact answer & settings 2 attempt records |
| Anthropic: Claude Sonnet 5.5 | Uncertain | Withholds a fit verdict because its recalled 7.5-to-8.5-foot cabin length spans the countertop length. Assumes rear seats folded and passenger seat reclined; requests actual dashboard-to-tailgate diagonal measurement rather than concluding no from delivery advice. | Exact answer & settings 2 attempt records |
| Meta: Muse Glimmer 30B | NO | Explicit no treats about 96 inches with the front passenger seat moved forward as the practical maximum and rejects additional angling because of slab width; does not establish other seat configurations or edge-on routes. | Exact answer & settings 2 attempt records |
| OpenAI: GPT-6 Luna | NO | Explicitly rejects fully enclosed fit even with long-cargo seat arrangements, assuming usable interior length below 98 inches and requiring the hatch closed. | Exact answer & settings 2 attempt records |
| SpaceXAI: Grok 4.7 | NO | Explicitly rejects both straight and diagonal closed-hatch fit, assuming rear seats folded and the front passenger seat moved fully forward rather than specifying a reclined seatback. | Exact answer & settings 2 attempt records |
| Anthropic: Claude Haiku 5.5 | NO | Explicitly rejects cabin fit using an assumed 60-to-65-inch rear-folded cargo length and a claimed dashboard-to-hatch diagonal below 98 inches; does not explore a distinct front-passenger-seat configuration. | Exact answer & settings 2 attempt records |
| Anthropic: Claude Opus 5.5 | NO | Explicit no for fully enclosed transport, treating 93-inch Long Mode with the passenger seat reclined and rear seat folded as limiting and rejecting diagonal placement. Allows only open-hatch carriage, with safety and legal caveats. | Exact answer & settings 2 attempt records |
| Google: Gemini 3.8 Flash | NO | Explicitly rejects enclosed fit based on an assumed 90–93-inch Long Mode limit, including a folded front passenger seat; its verdict requires the tailgate closed. | Exact answer & settings 2 attempt records |
| Google: Gemini 4 Argon | NO | Explicitly rejects closed-hatch fit using an assumed 93-inch Long Mode maximum; mentions packaging as longer still and permits only protruding or external transport. | Exact answer & settings 2 attempt records |
| IBM: Granite 4.2 8B | NO | Categorically denies physical fit by treating roughly 61 inches of rear-seat-folded cargo length as the vehicle maximum and adding a claimed 17–20-inch depth limit; does not consider a front-passenger or diagonal route. | Exact answer & settings 2 attempt records |
| Meta: Muse Spark Open | NO | Explicit no assumes fully enclosed, safely hatch-closed transport and a 90–95-inch maximum with the front passenger seat reconfigured; acknowledges hatch-open transport rather than denying every transport possibility. | Exact answer & settings 2 attempt records |
| Mistral: Ministral 3 3B 2512 | NO | Categorical no relies on asserted width, thickness and folded-cargo-volume limits. Its width rejection is internally inconsistent: the stated 25.58-inch slab depth is less than its stated 30–32-inch cargo width. | Exact answer & settings 2 attempt records |
| NVIDIA: Nemotron 3.5 Lightning | NO | Categorical physical-fit rejection relies on claimed 57–58-inch cargo length, a 72-inch cargo diagonal and under-80-inch total cabin length even with seats removed; leaves no possible route in its conclusion. | Exact answer & settings 2 attempt records |
| NVIDIA: Nemotron 3.5 Super VL | Uncertain | Explicit uncertainty remains unresolved: a claimed 96-inch front-passenger-folded length is too short straight, but a diagonal route might work depending on hatch and obstruction clearance. | Exact answer & settings 2 attempt records |
| OpenAI: GPT-6.1 Sol | Uncertain | Explicitly uncertain: the cited 93-inch Long Mode is shorter, but diagonal fit remains possible and requires loading-path and width measurements to establish hatch closure. | Exact answer & settings 2 attempt records |
| Upstage: Solar Mini 4 | Uncertain | Withholds an overall verdict despite claiming spare cargo volume; treats rigidity, loading clearance and possible disassembly or angling as unresolved rather than giving a probable yes or no. | Exact answer & settings 2 attempt records |
| Cohere: Command A+ | NO | Categorical no treats roughly 60 inches of folded-rear-seat cargo length as the maximum and asserts width and thickness also exceed trunk dimensions, without assessing a front-passenger or diagonal route. | Exact answer & settings 2 attempt records |
| DeepSeek: DeepSeek V4 Pro 0813 | Transport error | The request failed in transit; there is no scored answer. | Exact answer & settings 2 attempt records |
| inclusionAI: Ling 3.1 Flash | NO | Explicitly rejects fit, claiming even seat removal and diagonal placement leave insufficient interior length. | Exact answer & settings 2 attempt records |
| LiquidAI: LFM2.5-24B-A2B | NO | Explicit no accepts the depth and thickness but treats a claimed 41–68-inch cargo-compartment length as the available space, without assessing a front-passenger or diagonal route. | Exact answer & settings 2 attempt records |
| Mistral: Mistral Large 4 | NO | Explicit NO claims even rear/front-passenger folding leaves insufficient length and the slab width prevents using the theoretical diagonal. | Exact answer & settings 2 attempt records |
| Qwen: Qwen3.5-9B | Transport error | The request failed in transit; there is no scored answer. | Exact answer & settings 3 attempt records |
| Qwen: Qwen3.8 27B | NO | Explicitly rejects fit even with folded seats and diagonal placement, excluding seat removal from its cabin configuration. | Exact answer & settings 2 attempt records |
| Qwen: Qwen3.8 Flash | API error | The provider or API returned an error; there is no scored answer. | Exact answer & settings 2 attempt records |
| Qwen: Qwen3.8 Max Prime | NO | Explicitly rejects enclosed fit using an assumed 59–60-inch rear-seats-folded cargo floor and insufficient diagonal; does not evaluate passenger-seat/footwell reconfiguration. | Exact answer & settings 2 attempt records |
| Xiaomi: MiMo-V2.6-Flash | Transport error | The request failed in transit; there is no scored answer. | Exact answer & settings 2 attempt records |
| Z.ai: GLM 5.3 Prime | NO | Explicit NO assumes hatch closure and a maximum 90–95-inch diagonal; open-tailgate transport is distinguished from enclosed fit. | Exact answer & settings 2 attempt records |
