claude-code - 💡(How to fix) Fix [Bug] Opus 4.7 incorrect reasoning about URL normalization vs dereferencing [1 participants]

TL;DR

The issue may be resolved by adding evaluations to improve the model's understanding of URL normalization and dereferencing.

Guidance

• Review the training data to ensure it covers various URL normalization and dereferencing scenarios to prevent overfitting.
• Consider using MechInterp tools to analyze and improve the model's reasoning about URL differences.
• Evaluate the model's performance on a separate test set to identify potential biases or areas for improvement.
• Assess the risk of contaminating the model with overfitting when adding new evaluations.

Notes

The issue lacks specific technical details about the model's implementation or the exact errors encountered, making it challenging to provide a more targeted solution.

Recommendation

Apply workaround: Add evaluations to improve the model's understanding of URL normalization and dereferencing, while carefully monitoring for potential overfitting.
