how to prompt to get short response

[AllenDun]

Nice work. However, I tried some images and asked the model to output the description with short words or sentence, but it always given a long output. I tried prompts like these:
prompt: answer the question with one word: how many persons in the image? response: There are two persons in the image.
prompt: in the image, is it wearing a helmet on head? please answer with short words. response:No, the individual in the image is not wearing a helmet on their head. They are holding a yellow hard hat in their hands, which is typically worn for safety in construction or industrial settings.
prompt: is she wearing a helmet on head? answer the question with yes or no. response: No, she is not wearing a helmet on her head. She is holding a hard hat in her hands.

Hi, may I ask which model you are using? It seems the 2B and 7B models may not have great instruction-following ability. I try the same prompt but got the desired response with 13B and 34B models. Please try the 34B demo and 13B demo.

@yanwei-li I tried the demo on the huggingface, it should be 13B, right?
