In today's Smoke evaluation, Gemini 3.1 Pro's material constraint score dropped from 90.40 to 72.60, a decrease of 17.8 points, causing its main ranking to fall from 81.93 to 75.90.
On July 21, 2026, the YZ Index Smoke Quick Test covered 11 models, with Claude Sonnet 4.6 and GPT-o3 tying for first place at 96.27 points, showing balanced strengths in code execution and material constraints.
In today's Smoke evaluation, Qwen3 Max's main score dropped from 82.23 to 67.31, a decrease of 14.9 points, with the code execution dimension falling from 96.90 to 65.60.
In today's Smoke evaluation, Gemini 2.5 Pro's code execution score dropped from 74.60 to 50.00 points (a decrease of 24.6 points), while its overall ranking fell from 76.49 to 69.98 points.
On July 20, 2026, the YZ Index Smoke Quick Test covered 11 models, with Claude Opus 4.7 scoring 100 points to top the daily rankings. This Smoke test uses 10 questions per day, suitable for observing short-term signals, and is not equivalent to the Full weekly ranking conclusions.
In today's Smoke evaluation, Gemini 3.1 Pro's material constraint score fell from 90.90 to 64.30, a drop of 26.6 points, while its main ranking overall still rose by 5.4 points.
GPT-o3's main score in today's Smoke evaluation fell from 80.61 to 66.86, with code execution dropping from 70.30 to 48.50, a single-day decline of 21.8 points.
The seven-day Smoke evaluation from July 13 to July 19, 2026 shows Claude Opus 4.7 leading with an average score of 86.9, while GPT-o3 declined sharply by 30.5 points. The report also analyzes rising models such as Qwen3 Max, declining models like Doubao Pro, along with volatility and integrity ratings.
On 2026-07-19, the YZ Index Smoke Quick Test covered 10 models, with Claude Opus 4.7 ranking first at 95.19. Smoke is a daily 10-question quick test suitable for monitoring short-term signals and is not equivalent to Full weekly rankings.
GPT-o3 leads with a score of 80.61 in the YZ Index Smoke quick test on July 18, 2026, covering 11 models. The daily 10-question test focuses on code execution and material constraints, providing short-term signals rather than long-term conclusions.
Grok 4's main score in today's Smoke evaluation dropped from 94.15 to 76.65, a decline of 17.5 points. The material compliance dimension fell by 21.9 points in a single day.
DeepSeek V4 Pro's main score in today's Smoke evaluation dropped 11.9 points from yesterday's 93.84 to 81.93. Code execution decreased by 13.3 points, and material constraints by 10.2 points, while engineering judgment and task expression remained unchanged.
On July 17, 2026, the YZ Index Smoke quick test covered 11 models, with Gemini 2.5 Pro and Gemini 3.1 Pro tying for first place at 92.44 points. This Smoke test focused only on two main board dimensions: Code Execution and Material Constraints.
Doubao Pro's main score fell from 86.25 to 71.22 in today's Smoke evaluation, with code execution dropping from 75.00 to 58.30 and material adherence dropping from 100.00 to 87.00. The analysis points to question selection volatility rather than model degradation.
