ModelReviewed label / statusReview reason / coverage noteExact text & provenance
Google: Gemini 3.5 Flash LiteNOExplicit no with doors and tailgate closed, based on a claimed 80–84-inch maximum even with the passenger seat reclined; separately rejects protruding transport as unsafe.Exact answer & settings 2 attempt records
StepFun: Step 5 PreviewNOConcludes it will not fit without cutting or external transport, relying on normal rear-seat-folded cargo length and a continuous straight-run requirement rather than examining a reconfigured cabin diagonal.Exact answer & settings 2 attempt records
DeepSeek: DeepSeek V4.1 Flash 1017YESGives an explicit marginal/probable yes on edge along a cabin diagonal with the passenger side opened up, while leaving closed-hatch and dash/glass clearance uncertain.Exact answer & settings 2 attempt records
Meta: Muse WonderNOClearly rejects closed-hatch fit using a 93-inch Long Mode limit and flat-diagonal footprint constraints; allows hatch-open protrusion rather than full enclosure.Exact answer & settings 2 attempt records
Anthropic: Claude Sonnet 5.5NOEnds with a weak but explicit probable-no estimate for fitting cleanly, despite acknowledging a possible slanted passenger-seat configuration; hatch closure remains a consequential assumption.Exact answer & settings 2 attempt records
Meta: Muse Glimmer 30BNORejects closed-hatch fit even with the passenger seat folded, asserting under 90 inches of practical length and ruling out standing the slab on edge.Exact answer & settings 2 attempt records
OpenAI: GPT-6 LunaUncertainRejects a straight, flat closed-hatch load but leaves edge-on diagonal fit geometrically plausible and unresolved pending a test fit.Exact answer & settings 2 attempt records
SpaceXAI: Grok 4.7NORejects fully enclosed fit while allowing hatch entry; assumes seats, console and dash prevent a slab-width diagonal and excludes protrusion through an open hatch.Exact answer & settings 2 attempt records
Anthropic: Claude Haiku 5.5NOClearly rejects closed-hatch fit, assuming the passenger seat cannot fold flat and the usable cabin diagonal is only 85–90 inches.Exact answer & settings 2 attempt records
Anthropic: Claude Opus 5.5NOExplicitly leans no for hatch-closed fit, citing marginal Long Mode length and front-cabin width and rigidity constraints, while recommending measurement.Exact answer & settings 2 attempt records
Google: Gemini 3.8 FlashNOClearly rejects closed-hatch fit using a claimed 93-inch Long Mode limit and width-based rejection of diagonal loading; permits hatch-open protrusion.Exact answer & settings 2 attempt records
Google: Gemini 4 ArgonNORejects closed-hatch fit even unboxed, claiming width prevents use of the windshield diagonal; allows loading only with rear protrusion and adds safety concerns.Exact answer & settings 2 attempt records
IBM: Granite 4.2 8BNOExplicit no only under an added flat-on-cargo-floor restriction, excluding edge-on or tilted loading and front-passenger extension; claims approximately 45-by-17-inch usable space.Exact answer & settings 2 attempt records
Meta: Muse Spark OpenNORejects fully enclosed fit, claiming the US third-generation passenger seat lacks flat Long Mode and width defeats diagonal loading; requires an open hatch instead.Exact answer & settings 2 attempt records
Mistral: Ministral 3 3B 2512NOCategorically rejects fit regardless of seating, relying on separate 36–44-inch cargo sections and a width comparison that inconsistently switches the car's inches to centimeters.Exact answer & settings 2 attempt records
NVIDIA: Nemotron 3.5 LightningNOClearly rejects fit using the rear-seat cargo box and its floor diagonal, without assessing a front-cabin route; its claim that 25⅝ inches on edge exceeds 30.5-inch height contradicts its dimensions.Exact answer & settings 2 attempt records
NVIDIA: Nemotron 3.5 Super VLNORejects the optimistic guess and enclosed fit, assuming the front seatbacks prevent a usable cabin/footwell extension even after reclining.Exact answer & settings 2 attempt records
OpenAI: GPT-6.1 SolUncertainNormal flat loading with the hatch closed is judged unlikely, but unusual edge-on/3D loading remains explicitly possible and unverified; delivery advice is not an overall physical-fit no.Exact answer & settings 2 attempt records
Upstage: Solar Mini 4NOExplicitly rejects the intact slab even with front seats folded, assuming only 56–57 inches of usable length and hatch interference despite its larger stated opening dimensions; cut pieces are a different case.Exact answer & settings 2 attempt records
Cohere: Command A+NOUnequivocally rejects fit based on assumed short interior space, hatch and weight limits; its dimensional comparisons contradict its own numbers, including claiming the slab exceeds the whole vehicle's length.Exact answer & settings 2 attempt records

Qwen: Qwen3.8 FlashNOPredicts fully enclosed nonfit because diagonal clearance is probably insufficient; the possible alternative explicitly allows an open hatch and rear overhang.Exact answer & settings 2 attempt records

Xiaomi: MiMo-V2.6-FlashNOCategorically rejects interior fit using asserted maximum cargo length and floor diagonal, claiming an approximately ten-inch shortfall.Exact answer & settings 2 attempt records
Z.ai: GLM 5.3 PrimeYESClearly affirms diagonal fit using folded seats and an estimated dash/windshield route, but revises the slab to about 96.9 inches and allows hatch-ajar fallback; closed-hatch safe transport is not assured.Exact answer & settings 2 attempt records
