Grok 4.6

What it nailed

• Complete artifact set in real requested formats, with manifest, assumptions, sources, screenshots, and supporting assets.
• Excellent handling of the benchmark’s central traps: dingo/litter-box mismatch, Alaska versus Australia, NCI-created demand, permit ambiguity, ethics, support-language liability, and fictional competitors.
• Strong strategic package with staged budget gates, channel-specific posture, investor FAQ, retail-safe copy, and serious risk controls.
• Clean visual dashboard according to independent rendered review, with source imagery, readable charts, and responsive mobile behavior.
• Copywriting is unusually well calibrated across formal, casual, executive, playful, deadpan, and luxury tones.

Where it slipped

• TAM and 5-year hardware revenue math drifts across assumptions, deck, dashboard, and workbook formulas, even though the qualitative conclusion is consistent.
• Research sources are extensive and plausible, but the supplied validation evidence does not include an independent source-verification audit.
• Some regulatory/pricing citations rely on secondary or commercial mirrors where official sources would be preferable before external publication.
• The package is internally production-ready, but legal/regulatory claims still require counsel review before public use, as the artifacts themselves correctly acknowledge.

What it nailed

• Produces a real, openable SQLite warehouse with a broad normalized schema and review tables.
• Strong provenance architecture linking canonical records back to source records/files.
• Handles major structured canaries including SVC-007 collision, corrupted JSON recovery, duplicate image hashing, sensitive-file skip, and visible customer conflicts.
• Static reviewer UI is well organized and mostly polished, with useful search/filter/detail workflows.
• Documentation is unusually honest about tradeoffs and avoids claiming production readiness.

Where it slipped

• No OCR: handwritten receipt and whiteboard image contents are not semantically extracted, so several planted image-specific customers, price conflicts, and schedule/date issues remain only queued.
• Department/role-code normalization is not clearly represented in the canonical job schema.
• Several canary passes are model-authored claims in the canaries table rather than independently validated evidence.
• Final customer/job/service counts suggest possible over-splitting or extra promoted entities that would need human audit.
• Minor mobile UI navigation clipping was observed by one visual judge.

What it nailed

• [100-piece-lunar-rover] Required isolated-case artifact is present and runnable enough to produce desktop and mobile renders.
• [100-piece-lunar-rover] Parsed kitSpec contains exactly 100 parts, matching the declared 100-piece target.
• [100-piece-lunar-rover] The completed rover is visually recognizable and detailed, with brick studs, wheels, transparent cabin, and clean instructional UI.
• [100-piece-lunar-rover] The guide includes a structured multi-step assembly flow and the expected playback/review controls.
• [250-piece-rescue-helicopter] Delivered the required isolated case artifact at artifacts/index.html plus a separate kitSpec.json.
• [250-piece-rescue-helicopter] Exact 250-piece declared and measured spec, with a structured kitSpec and chaptered 58-step assembly guide.
• [250-piece-rescue-helicopter] Strong source-of-truth architecture: parts, step text, manifest-style data, and viewer code are centered on the kitSpec.
• [250-piece-rescue-helicopter] Clean UI shell with readable instruction cards, chapter panel, and obvious transport controls.
• [250-piece-rescue-helicopter] The kit concept includes the expected rescue-helicopter elements in the spec.
• [500-piece-cyberpunk-food-stall] Exact 500-piece structured kit data was present and parseable.
• [500-piece-cyberpunk-food-stall] Mechanical connectivity is comparatively strong: floating_fraction 0.076 with a 434-part largest component.
• [500-piece-cyberpunk-food-stall] The artifact includes a full browser UI with instruction panel, chapter navigation, playback controls, speed, scrubber, and show-complete controls.
• [500-piece-cyberpunk-food-stall] The concept and part data clearly target a cyberpunk street-food stall with appropriate themed elements.
• [1000-piece-airship-research-station] Required isolated-case artifact artifacts/index.html is present and self-contained with an inline kitSpec.
• [1000-piece-airship-research-station] Declared and extracted piece counts match at 1007 pieces, with a detailed 213-step assembly guide.
• [1000-piece-airship-research-station] Completed visual render is rich and recognizable as an airship research station/dock, with visible studs and recording-friendly UI.
• [1000-piece-airship-research-station] The guide includes the expected review controls and a parts-list interface.

Where it slipped

• [100-piece-lunar-rover] Authoritative connectivity validation finds 20% of parts floating under strict stud-coupling rules.
• [100-piece-lunar-rover] The model decomposes into 17 mechanical components, with only 35 parts in the largest component.
• [100-piece-lunar-rover] near_miss_count=369 is high for a 100-piece build and indicates many approximate contacts rather than precise stud engagement.
• [100-piece-lunar-rover] Mobile completed framing is somewhat cramped/cropped.
• [100-piece-lunar-rover] Full independent verification of every interactive control was not provided.
• [250-piece-rescue-helicopter] Mechanical buildability is poor under the authoritative strict validator: 38% of pieces are floating and the build splits into 61 components.
• [250-piece-rescue-helicopter] The completed-build visual failed in operator screenshots; the required helicopter was absent from completed desktop and mobile captures.
• [250-piece-rescue-helicopter] High near_miss_count shows many parts were placed approximately rather than engaged on a valid stud grid.
• [250-piece-rescue-helicopter] Final hero orbit/show-complete workflow cannot be trusted from the rendered evidence.
• [250-piece-rescue-helicopter] Some strong validation/control claims are uncorroborated or contradicted by independent rendered evidence.
• [500-piece-cyberpunk-food-stall] Primary completed-state visual evidence is blocking: the finished stall is not shown, only the initial foundation step.
• [500-piece-cyberpunk-food-stall] The show-complete/completed-review path appears broken or at least not independently verified as working.
• [500-piece-cyberpunk-food-stall] 38 parts are measured as floating and the build is split into 42 components.
• [500-piece-cyberpunk-food-stall] near_miss_count=3152 indicates many approximate placements rather than clean stud engagement.
• [1000-piece-airship-research-station] Mechanical validation finds 263 floating parts and a 0.2612 floating_fraction, preventing high physical-buildability credit.
• [1000-piece-airship-research-station] 177 measured components and 5924 near misses indicate many pieces are approximately placed rather than strictly stud-coupled.
• [1000-piece-airship-research-station] Some subassemblies may be visually close but not physically attached under the strict connector metric.
• [1000-piece-airship-research-station] Mobile completed framing is close-cropped, and one judge observed a non-initial state appearing at Step 213/213.

What it nailed

• Complete artifact set with fact sheet, source notes, visualization, documentation, screenshots, and recording helper pages.
• Strong mission-specific coverage of crew, vehicle, timeline, free-return flyby, TLI, reentry, splashdown, and recovery.
• Good citation discipline within the artifact: primary vs secondary sources are separated and reconstructed visualization values are labeled.
• Interactive visualization is nonblank and includes scrubber, controls, HUD, phase cards, and meaningful scene/state changes.

Where it slipped

• Operator-confirmed major visual defects on the primary visualization trigger the v2 hard cap.
• Mobile presentation has overlapping HUD/header text and loses the central 3D vehicle subject.
• Desktop launch-vehicle framing is clipped near the top edge.
• Source support was not independently URL/content-validated in the provided validation evidence.
• The visualization depends on external CDN modules for Three.js rather than being fully self-contained.
