Code Correction Issued for Chapter 6 of 'Build a Reasoning Model (From Scratch)'

The creators of "Build a Reasoning Model (From Scratch)" have flagged an error in Listing 6.5 on page 198 that necessitates a small but critical code adjustment. A seed initialization parameter must be changed from 0 to 5 to ensure the generated outputs and log-probability values in Chapter 6 align with the lesson's demonstrated results. While the correction requires only a single character modification, it is crucial for readers seeking to accurately reproduce the expected outcomes. Without this fix, the code functions correctly but numerical results may diverge, potentially creating confusion for learners working through the material.
