Arithmetic versus Hindi math
2026-03-13 · Arithmetic captchas
Both return a computed text. Only Hindi images should set the Hindi flag.
math: true is the Western-digit sum. math and hindi together is the Devanagari word sum. The response engine field is how you confirm which path ran.
A Latin-digit sum sent with hindi: true is the wrong engine. You will not get a better 14+9 by asking the Hindi model to read it.
The accuracy numbers are also separate. Do not quote the Hindi 100% figure for ordinary arithmetic, and do not quote the arithmetic 95% figure for Hindi words.
Pricing does not change by engine. One reliable answer is one credit on all three.
