GPT-o3 Material Constraint Drops 16.8 Points, Task Expression Falls 28.3 Points

GPT-o3 scored 66.80 in material constraint in today's Smoke evaluation, a drop of 16.8 points from yesterday's 83.60, and the main ranking total fell from 83.44 to 80.39.

Score Change Details

Code execution rose from 83.30 to 91.50, engineering judgment remained unchanged at 75.00, task expression dropped from 95.00 to 66.70, and integrity rating remained pass.

Possible Cause Analysis

The Smoke evaluation has only 10 questions per day, with high individual question weight. The simultaneous sharp decline in material constraint and task expression is most likely due to changes in content distribution caused by question sampling, rather than structural degradation of model capability. The code execution score increased by 8.2 points, indicating stable model output in that dimension. The opposite movements in the two dimensions further support that the fluctuation stems from sample variation rather than overall degradation.

Implications for Users

For scenarios heavily reliant on material fidelity, such as contract clause extraction or policy text verification, manual review steps should be added before calling GPT-o3. The improved code execution performance has a smaller impact on developers handling algorithm verification and data processing tasks, who can continue using it but should still monitor cross-dimension consistency.

Strategic Assessment

Given the simultaneous decline in material constraint and task expression, combined with the small sample nature of Smoke evaluation, current signals are insufficient to conclude a real capability drop in the model. It is recommended to focus on whether both dimensions persist below 75 points in the next evaluation. If single-day fluctuation repeats in subsequent tests, GPT-o3 should be removed from the preferred list for material-sensitive tasks.
