WDCD v3.1: Four Models Up, Two Down as GPT-6 Luna Leads with a Perfect 100 and Doubao Pro Gains 20.3

The latest WDCD v3.1 pilot round shows GPT-6 Luna scoring 100.00 to top the current Top 5, while Doubao Pro jumped 20.3 points over Run #384 and Gemini 2.5 Pro and GPT-5.5 each dropped 6.2 points. Four models rose and two fell across the 15 models evaluated on a mixed pool of multi-turn progressive-pressure questions and three-round anchor questions.

WDCD Five-Scenario Cross-Evaluation: Engineering Specification Hits a Low of 1.95; Data Boundary’s 1.7 Becomes the Biggest Killer

In the WDCD v3.1 pilot, worst-of-3 scores for 15 models across five constraint scenarios show that engineering specification and data boundaries are the hardest dimensions for commitment compliance, with lows of 1.95 and 1.7, respectively.

R3 Integrity Rate 76.7% Yet Two Zero Scores: A 15-Model Three-Round Anchor Decay Test

In the WDCD v3.1 pilot, 15 models averaged a 0.93 R1 acknowledgment rate, a 0.67 R2 resistance rate, and only a 76.7% R3 integrity rate, with two full-collapse cases out of 150. The decay pattern shows that some models maintain constraints across all three anchor rounds, while others verbally agree but break under pressure.

GPT-6 Luna Wins WDCD Commitment-Keeping Leaderboard with 100 Points; Qwen3 Max Last at 76.5, a 23.2-Point Gap

GPT-6 Luna tops the WDCD leaderboard with 100.00 points, while Qwen3 Max is last at 76.5, a 23.2-point gap; the article also reports Gemini 2.5 Pro at 73.80. Among the 15 models, 66% reach full marks, and the R3 crash rate is only 1.3%.

Claude Opus 4.7 Tops the List with 84.9 Points: 2026-10-21 Smoke Quick-Test Data Brief

The 2026-10-21 YZ Index Smoke quick test covered 14 models, with Claude Opus 4.7 taking first place for the day at 84.9 points. Smoke is a daily 10-question quick test suited to spotting short-term signals, and it is not equivalent to the conclusions of the weekly Full leaderboard.

Qwen3 Max Smoke Evaluation Missing All Five Dimensions, API Failure Leads to Zero Record on Main Leaderboard

Qwen3 Max scored zero across all five dimensions in today's Smoke evaluation due to an API failure, with no main leaderboard record and exclusion from this period's rankings.

GPT-6 Astra Code Execution Plummets 25 Points; Main Leaderboard Falls 11.3 Points in a Single Day

In today's Smoke evaluation, GPT-6 Astra's main leaderboard score fell from 82.33 to 71.01, with the code execution dimension dropping from 97.00 to 72.00. The 25-point drop in code execution drove an 11.3-point decline in the weighted main leaderboard score.

GPT-o3 Leads with 97.83: 2026-10-20 Smoke Quick Test Data Brief

The 2026-10-20 YZ Index Smoke quick test covered 14 models, with GPT-o3 ranking first for the day at 97.83. Smoke is a daily 10-question quick test suitable for observing short-term signals and is not equivalent to conclusions from the weekly Full leaderboard.

GLM-4.6 Material Constraint Score Plummets 30.2 Points, Code Execution Rises 22 Points

In today's Smoke evaluation, GLM-4.6's material constraint score fell 30.2 points to 50.00, while code execution rose 22 points to 47.00. The main leaderboard score dropped only 1.5 points, suggesting sampling fluctuation rather than real model degradation.

DeepSeek V4 Pro Main Leaderboard Drops 18.6 Points; Material Constraint Falls 27.6 in One Day as Biggest Drag

DeepSeek V4 Pro’s main leaderboard score fell 18.6 points to 49.52 in today’s Smoke evaluation, with material constraint down 27.6 points in a single day and code execution down 11.3 points. The material constraint dimension was the largest drag, while task expression rose slightly; the data reflect a single-day result and cannot yet establish a change in model capability.

GPT-5.5 Tops with 93.54 Points: 2026-10-19 Smoke Quick Test Data Brief

GPT-5.5 led the October 19, 2026 YZ Index Smoke quick test with 93.54 points, followed by Grok 4 at 92.6. Because Smoke uses a small daily sample, single-day scores should be treated as monitoring signals rather than definitive capability conclusions.

Claude Sonnet 4.6 Gains 6.2, Qwen3 Max Drops 11.9 as WDCD Commitment-Keeping Capability Divergence Widens

This WDCD v3.1 pilot shows significant score changes in only Claude Sonnet 4.6 and Qwen3 Max: Claude Sonnet 4.6 rises 6.2 points while Qwen3 Max falls 11.9 points, leaving the Top 5 unchanged. The divergence highlights how multi-round pressure exposes differences in S_hold survival and S_integrity self-reporting.

Data Boundary Category Collapses Hardest: Claude Scores 3.72, Qwen Just 1.36

In the WDCD v3.1 five-scenario cross-evaluation, the data boundary scenario recorded the lowest compliance scores across all models, with claude-sonnet-4.6 topping the field at 3.72/4 and qwen3-max trailing at just 1.36/4. The 2.36-point spread is far wider than in any other scenario, revealing sharp differences in how well models hold constraints under sustained pressure.

15 Models Show 48.9% R3 Integrity Rate: Qwen3 Max Collapses 8 Times, Claude Zero

Based on the sampling of 8 v2 anchor questions, the WDCD v3.1 pilot shows that 15 models averaged only 48.9% integrity at R3, with 39/435 complete R3 collapses. Qwen3 Max collapsed in all 8 of its cases, while Claude Opus 4.7 recorded zero.

Grok 4 Tops WDCD Commitment Leaderboard with 91.97 Points; Qwen3 Max Trails at 61.55 by a Wide Margin

In the WDCD v3.1 commitment test, Grok 4 ranked first among 15 models with 91.97 points, while Qwen3 Max finished last with 61.55, a 30.42-point gap. Qwen3 Max scored zero on all v2 anchor questions across the R1, R2, and R3 stages.

Claude Opus 4.7 Leads with 81.91 Points: 2026-10-18 Smoke Quick Test Data Brief

Claude Opus 4.7 tops the 2026-10-18 YZ Index Smoke quick test with 81.91 points across 14 models, followed by Doubao Pro at 77.34 and Grok 4 at 72.09. Several models posted steep single-day declines, which the brief treats as monitoring signals rather than long-term conclusions.

DeepSeek V4 Pro Material Constraint Score Plunges 18.1 Points, Yet Code Execution Hits a Perfect 100

In today's Smoke evaluation, DeepSeek V4 Pro's material constraint score fell from 88.10 to 70.00, a drop of 18.1 points, while code execution rose from 72.00 to 100.00 and the main leaderboard score climbed from 79.25 to 86.50. The opposing swings in two dimensions most likely reflect random question sampling rather than model degradation.

Gemini 3.1 Pro Material Constraint Score Falls 15.3 Points While Code Execution Rises to 100

In today's Smoke evaluation, Gemini 3.1 Pro's material constraint score dropped from 88.10 to 72.80, a decline of 15.3 points, while its code execution score rose from 54.50 to 100.00 and its main leaderboard score climbed from 69.62 to 87.76. The shift is more likely due to sampling variance than a genuine decline in model capability.
