| Model | Reviewed label / status | Review reason / coverage note | Exact text & provenance |
|---|---|---|---|
| Google: Gemini 3.5 Flash Lite | YES | Overall affirmative with rear and passenger seats flat; later explicitly says the hatch will not close, treating protruding hatch-open carriage as fit. | Exact answer & settings 1 attempt records |
| StepFun: Step 5 Preview | YES | Clearly affirms a tight diagonal fit with rear seats down and the passenger seat moved/folded forward. Says normal rear-seats-up loading fails and that warping or tight hatch/headliner clearance could defeat the fit, without withdrawing its overall yes. | Exact answer & settings 2 attempt records |
| DeepSeek: DeepSeek V4.1 Flash 1017 | YES | Overall affirmative for an on-edge diagonal load with rear seats down and passenger seat reclined; it warns that the hatch may need to remain partly open and calls fully enclosed fit borderline. | Exact answer & settings 1 attempt records |
| Meta: Muse Wonder | YES | Affirms a tight diagonal fit using Long Mode and says the hatch should latch; seat adjustment, securing the load, and an open-hatch fallback are practical caveats rather than a retraction. | Exact answer & settings 1 attempt records |
| Anthropic: Claude Sonnet 5.5 | Uncertain | Presents unresolved possibilities and makes fit conditional on measuring sufficient clearance, not an affirmative verdict about this car. | Exact answer & settings 1 attempt records |
| Meta: Muse Glimmer 30B | NO | Clear practical no: it allows a theoretical diagonal arrangement but says that arrangement cannot close the hatch safely and is not transportable. | Exact answer & settings 1 attempt records |
| OpenAI: GPT-6 Luna | NO | Explicitly rejects fit with the added closed-hatch requirement, citing nominal long-mode length and declining to rely on a diagonal placement. | Exact answer & settings 1 attempt records |
| SpaceXAI: Grok 4.7 | NO | Rejects fit with the hatch closed, an added assumption not stated in this prompt. Treats the available straight load length as too short; this label records its verdict, not independent validation of those measurements. | Exact answer & settings 1 attempt records |
| Anthropic: Claude Haiku 5.5 | Uncertain | Hedges between difficulty and a possible angled fit with the front passenger seat folded; never resolves whether it fits or the hatch closes. | Exact answer & settings 1 attempt records |
| Anthropic: Claude Opus 5.5 | NO | Overall verdict is probably not, qualified by added safe-transport and closed-hatch assumptions rather than an unrestricted physical-fit question. | Exact answer & settings 1 attempt records |
| Google: Gemini 3.8 Flash | NO | Rejects complete interior fit under an added closed-hatch condition, while allowing hatch-open carriage with the countertop protruding. | Exact answer & settings 1 attempt records |
| Google: Gemini 4 Argon | NO | Overall no assumes the rear hatch must close; explicitly allows transport with the hatch open and some countertop protruding. | Exact answer & settings 1 attempt records |
| IBM: Granite 4.2 8B | NO | Overall no based on its claimed length limit with rear seats folded. It assumes flat or near-flat practical transport and expressly excludes diagonal loading on safety and damage grounds. | Exact answer & settings 1 attempt records |
| Meta: Muse Spark Open | NO | Overall no for safe, closed-hatch fit, particularly straight and fully supported; it allows mathematical diagonal wedging and an ajar hatch but treats those as unsafe or damaging alternatives. | Exact answer & settings 1 attempt records |
| Mistral: Ministral 3 3B 2512 | NO | Clear physical-fit rejection based on claimed cargo limits even with seats folded, rather than a confidence-threshold response. | Exact answer & settings 1 attempt records |
| NVIDIA: Nemotron 3.5 Lightning | NO | Unambiguously rejects interior fit even with all seats folded and argues that both extended length and diagonal clearance are insufficient. | Exact answer & settings 1 attempt records |
| NVIDIA: Nemotron 3.5 Super VL | NO | Explicitly says no to fully enclosed fit with the doors closed; treats hatch-open protrusion as outside the requested interior fit rather than an affirmative workaround. | Exact answer & settings 1 attempt records |
| OpenAI: GPT-6.1 Sol | NO | Advises against counting on fit with the added fully closed-hatch requirement; explicitly leaves diagonal physical fit unresolved. | Exact answer & settings 1 attempt records |
| Upstage: Solar Mini 4 | NO | Clearly says the countertop cannot fit and calls it physically impossible. The explanation relies on cargo length behind the rear seats rather than assessing a fully reconfigured cabin; safe-transport advice is secondary, not a hatch-closure or safety condition on the verdict. | Exact answer & settings 1 attempt records |
| Cohere: Command A+ | NO | Explicitly says no based on claimed cargo-area length, volume, and loading limits, adding a weight/load-rating objection. The conclusion is physical non-fit, not merely a safety or hatch-closure caveat. | Exact answer & settings 1 attempt records |
| DeepSeek: DeepSeek V4 Pro 0813 | NO | Says the intact countertop will not fit because its claimed 93–94-inch maximum with the passenger seat folded is shorter than 98 inches, and the slab's depth prevents gaining enough diagonal room. | Exact answer & settings 2 attempt records |
| inclusionAI: Ling 3.1 Flash | NO | Clearly rejects fit on the added condition that the car must close fully, attributing the problem to length rather than width or thickness. | Exact answer & settings 1 attempt records |
| LiquidAI: LFM2.5-24B-A2B | NO | Clearly denies interior fit in any practical orientation based on its claimed cargo length and hatch-opening dimensions; this is a physical-fit verdict, not a confidence-threshold refusal. | Exact answer & settings 1 attempt records |
| Mistral: Mistral Large 4 | YES | Explicitly affirms a very tight, steep diagonal fit with rear/passenger seats folded and both front seats moved forward. Warns of driver/console interference and that the hatch may need to stay ajar, so the yes is not a guarantee of enclosed or unobstructed transport. | 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 | Empty answer | The request did not produce a non-empty final answer. | Exact answer & settings 3 attempt records |
| Qwen: Qwen3.8 Flash | Transport error | The request failed in transit; there is no scored answer. | Exact answer & settings 3 attempt records |
| Qwen: Qwen3.8 Max Prime | NO | Treats fitting inside as a reliable, fully enclosed, hatch-closed fit and says no, even with passenger-seat Long Mode near its length limit. Allows a measured diagonal or protruding load only as maybe, not a confident enclosed fit. | Exact answer & settings 2 attempt records |
| Xiaomi: MiMo-V2.6-Flash | NO | Rejects both cargo-area and full-cabin diagonal fit with rear seats folded and front seats forward, claiming insufficient length. Explicitly distinguishes a strapped, protruding load through an open hatch from fitting inside. | Exact answer & settings 2 attempt records |
| Z.ai: GLM 5.3 Prime | YES | Overall verdict is affirmative with diagonal placement and passenger-seat repositioning; it expressly allows the hatch to remain slightly ajar, so the yes does not guarantee fully enclosed fit. | Exact answer & settings 1 attempt records |
