Truncated un-finished response after deploying hugging-face models

I have deployed a couple of LLMs, Zypher and llama 13 among others and changed the max-token and other related parameters, but each time after inference I get a couple of tokens and an incomplete response. Not sure what am I doing wrong. Any help much appreciated.

My prompt is large and has some instructions. (format is decorated based on the model)

import boto3
from sagemaker.huggingface import HuggingFaceModel, get_huggingface_llm_image_uri

try:
	role = sagemaker.get_execution_role()
except ValueError:
	iam = boto3.client('iam')
	role = iam.get_role(RoleName='sagemaker_execution_role')['Role']['Arn']
