What caught my eye was:

            Model  Lines of Code  File Size  Gzip Size 
      GPT-5.6 Sol          1,264    35.5 KB    10.0 KB 
    GPT-5.6 Terra            827    20.0 KB     6.7 KB

Yea, that's an interesting result as well. The Terra apps don't feel 35% less feature-rich. So it seems quite token efficient.
