For Flores, we use SSA-COMET (Li et al., 2025); for AfriMGSM, we detect the number inside the \boxed{} or the last number in the entire output; for multiple-choice questions, we use exact match.

Usage

Served with vLLM. The checkpoint declares Qwen3_5ForConditionalGeneration but carries no vision weights (426 language-model tensors plus an untied lm_head, 0 visual), so --language-model-only is required.

Hatua ya 1: Sandy hupata $15 kwa saa.
Hatua ya 2: Sandy alifanya kazi saa 10 Ijumaa.
Hatua ya 3: Jumla ya Mapato = $15/saa x saa 10
Hatua ya 4: $15 x 10 = $150

Sandy alipata $150 kwa kufanya kazi saa 10.

Recommendation Prompting and Setting

Mathematics

English

You are a helpful assistant that solves math word problems.
Please reason step by step in English, and put your final answer within \boxed{}.

For other languages, replace the part after "step by step in" with the target language, and translate it into the target language, for example Swahili:

Wewe ni msaidizi mwenye manufaa ambaye hutatua matatizo ya hisabati yaliyoandikwa kwa maneno.
Tafadhali toa hoja hatua kwa hatua kwa Kiswahili, na uweke jibu lako la mwisho ndani ya \boxed{}.
