In the WDCD v3.1 pilot, the Business Rules scenario scored the lowest overall, with champion claude-opus-4.7 achieving only 3.5/4 and bottom-ranked qwen3-max scoring just 1.3/4, far below the champion scores of the other four scenarios.
In a worst-of-3 sampling of only 8 v2 anchor questions, the average R3 integrity rate across 11 models was merely 61.4%, while R1 confirmation rate remained as high as 95% and R2 resistance rate 73%, revealing the true performance of mainstream models under hard constraints.
Grok 4 leads the WDCD Compliance Leaderboard with 95.00 points, while Claude Sonnet 4.6 ranks 11th with 64.10 points, a gap of 30.9 points.
The 2026-07-08 YZ Index Smoke Quick Test covered 10 models, with DeepSeek V4 Pro ranking first at 95.19 points. Smoke is a daily 10-question quick test suitable for observing short-term signals and is not equivalent to the Full weekly ranking conclusions.
On 2026-07-07, the Winzheng YZ Index Smoke Quick Test covered 11 models. Claude Opus 4.7 and Grok 4 tied for first place with a score of 96.99.
In the YZ Index Smoke Quick Test on July 6, 2026, Doubao Pro ranked first with a Main Board score of 83.91, covering 11 models in 10 daily questions. The test focuses on code execution and material constraints, serving as a short-term monitoring signal rather than a long-term conclusion.
In the Smoke Quick Test Run#214 on 2026-07-05, GLM-4.6 scored 60.04 on the main leaderboard, with code execution at 88.70, material constraint at 25.00, integrity rating fail, and probe score 0.00.
On July 5, 2026, the YZ Index Smoke Quick Test covered 11 models, with Doubao Pro and Gemini 3.1 Pro tying for first place at 88.54 points. Smoke is a daily 10-question quick test for observing short-term signals and is not equivalent to the Full weekly ranking.

In the June 2026 Smoke evaluation of the YZ Index, Qwen3 Max's main leaderboard score fell from 84.92 to 72.02, a drop of 12.9 points, with the code execution dimension plummeting from 96.30 to 69.50.
In the Smoke Lite evaluation of 11 models on July 4, 2026, by the YZ Index, Gemini 2.5 Pro ranked first with a Main Board score of 96.99, while Qwen3 Max's Main Board score plunged 12.9 points to 72.02.
In the WDCD v3.1 compliance test, the business rules scenario scored the lowest among all models, with grok-4 leading at 3.5/4, while doubao-pro and qwen3-max only scored 1.55/4.
In 275 samples on 8 v2 anchor questions, the average R1 confirmation rate was 0.99, but the R3 integrity rate was only 30.2%, with 44 complete collapses (score 0). This data directly reveals the rapid degradation pattern of models after initial commitment as rounds increase.
Grok 4 tops the WDCD Compliance Leaderboard with 91.20 points, while Qwen3 Max ranks last with 57.48 points, a gap of 33.72 points between the top and bottom.
In the Smoke lightweight benchmark on July 3, 2026, GPT-5.5 ranked first with a main score of 86.95, driven by a perfect code execution score of 100, while its material constraint score of 71 highlights a common weakness.
In the YZ Index Smoke lightweight evaluation on July 2, 2026, Gemini 3.1 Pro achieved first place on the main leaderboard with 82.97 points (Execution 75, Material Constraint 92.7), while Doubao Pro ranked second with 81.98 points (Execution 75, Material Constraint 90.5), both tied for the highest execution score.
In the WDCD three-round test, Grok 4 maintained a perfect score of 2 in all 10 R3 questions, while GPT-5.5 suffered 5 zero-score crashes, with an average R3 integrity score of only 1.00/2.
In the latest WDCD commitment test, Grok 4 achieved a perfect 100 points, while GPT-5.5 ranked last at 62.5 points. The results reveal a clear hierarchy, with top models excelling across all phases and bottom models collapsing under interference and pressure.
In the YZ Index June 2026 live test of 11 models, Doubao Pro’s Smoke Evaluation main ranking fell from 85.91 yesterday to 67.32 today, a drop of 18.6 points, primarily due to the code execution dimension falling from 83.30 to 44.50.
In today's YZ Index Smoke evaluation, Grok 4's main score dropped from 97.98 to 82.73, a decrease of 15.3 points, and code execution fell from 100.00 to 68.60. The single-day volatility is significant but consistent with small-sample draw characteristics, not necessarily indicating model degradation.
