GPT-5.5 and GPT-o3 Tie at 97.25 Points: 2026-08-13 Smoke Quick Test Data Briefing

On 2026-08-13, the YZ Index Smoke quick test covered 11 models, with GPT-5.5 and GPT-o3 tying for first place at 97.25 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.

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

Daily Ranking

Key Changes

• GPT-5.5: Main Score up 36 points, Code Execution +45 points, Material Constraints +25 points
• GPT-o3: Main Score up 22.3 points, Code Execution +20 points, Material Constraints +25 points
• Claude Sonnet 4.6: Main Score up 16.8 points, Code Execution +20 points, Material Constraints +12.9 points
• Qwen3 Max: Main Score up 15.4 points, Material Constraints +37.9 points
• DeepSeek V4 Pro: Main Score up 13.4 points, Material Constraints +35 points

Signals to Watch

• Gemini 2.5 Pro: Main Score dropped sharply by 9.1 points

When reading this type of Smoke briefing, focus should be on two questions: first, whether a model has repeatedly exposed the same type of weakness over consecutive days; second, whether the integrity rating has moved from pass to warn or fail. Large single-day swings in execution or constraint scores may stem from question sampling, or could be early signals of genuine degradation, requiring follow-up runs for verification.
