Claude Opus 4.7 and Grok 4 Tie at 96.99: 2026-07-07 Smoke Quick Test Data Brief

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. Smoke is a daily 10-question quick test, suitable for observing short-term signals, and is not equivalent to the Full weekly ranking conclusions.

This Smoke evaluation only covers two main dimensions: Code Execution and Material Constraints. The main ranking formula is 0.55 × Code Execution + 0.45 × Material Constraints. Due to the small daily sample size, single-day scores are more suitable as monitoring signals rather than long-term conclusions about model capabilities.

Data Interpretation

Today's Smoke Quick Test shows that Claude Opus 4.7 and Grok 4 have a main score of 96.99 each, with Code Execution of 100 and Material Constraints of 93.3, forming a structure of perfect Code Execution paired with high Material Constraints; Claude Sonnet 4.6 has a main score of 91.44, Code Execution 98.5, Material Constraints 82.8, with Material Constraints lower than the top two but still maintaining a relatively high main ranking; GPT-5.5 has a main score of 82.77, Code Execution 100, Material Constraints 61.7, showing a combination of perfect Code Execution with weaker Material Constraints.

Claude Opus 4.7's main score increased by 26.8 points, Code Execution +50; Claude Sonnet 4.6 main score +19.9, Code Execution +48.5, and Material Constraints -15; Grok 4 main score +17.6, Code Execution +33.3. These models showed significant improvement in the Code Execution dimension; 豆包 Pro main score -16.4, Material Constraints -67; GLM-4.6 main score -14.5, Code Execution -50, and Integrity changed from pass to warn. As a small-sample single-day signal, the above changes may be due to question sampling fluctuations or actual degradation, and require subsequent runs for verification.

Key Changes

  • Claude Opus 4.7: Main score up 26.8 points, Code Execution +50
  • Claude Sonnet 4.6: Main score up 19.9 points, Code Execution +48.5, Material Constraints -15
  • Grok 4: Main score up 17.6 points, Code Execution +33.3
  • 豆包 Pro: Main score down 16.4 points, Code Execution +25, Material Constraints -67
  • GLM-4.6: Main score down 14.5 points, Code Execution -50, Material Constraints +28.9, Integrity pass → warn

Signals to Watch

  • No abnormal signals worth publishing were retained this time.

When reading this type of Smoke brief, the focus should be on two questions: first, whether a model exposes the same type of weakness for multiple consecutive days; second, whether the integrity rating changes from pass to warn or fail. Large single-day changes in execution or constraint scores may be due to question sampling or could be early signals of actual degradation, requiring subsequent runs for verification.
