What the models said for it

Verbatim evidence the judge attached to positive labels.

“I'd typically recommend starting with Google Address Validation or Melissa” MiniMax M2.5 · Address verification · paraphrase prompt · first choice

“1. Google Address Validation API — Best Free Ongoing Option” Kimi K2 · Address verification · budget prompt · first choice

“U.S. ecommerce checkout: Compare Smarty and Google” GPT-6 Luna · Address verification · comparative prompt · first choice

“Unrivaled consumer-facing mapping and global visual autocomplete... Limitations: It is often "too permissive" for shipping logistics.” Gemini 3.5 Flash · Address verification · comparative prompt · alternative

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“Generally not CASS-certified, so less ideal for postal compliance needs” DeepSeek V4 Flash · Address verification · comparative prompt · soft negative
