Qwen3-4B-Instruct-2507-Math-Fr

This model is obtained by merging SamsungSAILMontreal/Qwen3-4B-Instruct-2507-Math and SamsungSAILMontreal/Qwen3-4B-Instruct-2507-Fr. The model is used in the experiments described in https://bknyaz.github.io/blog/2026/meta-merge/. Single A100 was used for merging and evaluation.

The following versions were used for merge/eval:

python >= 3.10
torch : 2.9.0+cu128
lm_eval : 0.4.9.1
vllm : 0.11.1
transformers : 4.57.6
datasets : 3.2.0
numpy : 2.2.6

Merging

Merging was done using parameter averaging implemented in merge_qwen.py.

Evaluation

Evaluation was done with lm_eval on the test split of gsm8k, french_bench (avg score) and gsm8k-fr:

python -m lm_eval --model vllm --model_args pretrained=${model},tensor_parallel_size=1,dtype=auto,gpu_memory_utilization=0.9,data_parallel_size=1 \
 --tasks gsm8k,french_bench,gsm8k-fr --batch_size 1 --apply_chat_template=True --confirm_run_unsafe_code --trust_remote_code

To evaluate on gsm8k-fr you can use our fork https://github.com/bknyaz/lm-evaluation-harness/tree/main/lm_eval/tasks/gsm8k.
