How do I avoid LLM rambling?

I’m using Meta-Llama-3-8B with transformers.pipeline, and even if I ask a simple question, it will respond and start hallucinating and generating text as if it were talking to itself.

I tried to make some changes to my pipeline settings based on some information I found here, but nothing helped, can anyone help me here?

This is how I define my pipeline:

model_dir = ‘/data/Meta-Llama-3-8B’
nf4_config = BitsAndBytesConfig(
load_in_8bit=True,
bnb_4bit_compute_dtype=torch.bfloat16
)

model = AutoModelForCausalLM.from_pretrained(
pretrained_model_name_or_path=model_dir,
device_map=“auto”,
quantization_config=nf4_config,
trust_remote_code=True
)

tokenizer = AutoTokenizer.from_pretrained(
model_dir,
add_eos_token=True,
use_fast=True
)

model.generation_config.max_new_tokens = 512
model.generation_config.temperature = 0.0001
model.generation_config.top_p = 0.95
model.generation_config.do_sample = True
model.generation_config.repetition_penalty = 1.15

pipe = pipeline(
“text-generation”,
model=model,
tokenizer=tokenizer,
return_full_text=False,
generation_config=model.generation_config,
)

This is an example of a simple question:

print(pipe(“I have eggs, flour, sugar, chocolate and milk. What dessert could I do with these ingredients? Sugest only one, and be concise”)[0][‘generated_text’])
