Text generation AI models generating repeated/duplicate text/sentences. What am I doing incorrectly? Hugging face models - Meta GALACTICA

Whole day I have worked with available text generation models

Here you can find list of them : Models - Hugging Face

I want to generate longer text outputs, however, with multiple different models, all I get is repetition.

What am I missing or doing incorrectly?

I will list several of them

Freshly released meta GALACTICA - facebook/galactica-1.3b · Hugging Face

The code example

from transformers import AutoTokenizer, OPTForCausalLM

tokenizer = AutoTokenizer.from_pretrained("facebook/galactica-1.3b")
model = OPTForCausalLM.from_pretrained("facebook/galactica-1.3b", device_map="auto")

input_text = "The benefits of deadlifting\n\n"
input_ids = tokenizer(input_text, return_tensors="pt").input_ids.to("cuda")

outputs = model.generate(input_ids,new_doc=False,top_p=0.7, max_length=1000)

The generated output

enter image description here

Facebook opt - facebook/opt-350m · Hugging Face

The tested code

from transformers import GPT2Tokenizer, OPTForCausalLM

model = OPTForCausalLM.from_pretrained("facebook/opt-350m")
tokenizer = GPT2Tokenizer.from_pretrained("facebook/opt-350m")

prompt = "The benefits of deadlifting can be listed as below:"
inputs = tokenizer(prompt, return_tensors="pt")

# Generate
generate_ids = model.generate(inputs.input_ids, max_length=800)
tokenizer.batch_decode(generate_ids, skip_special_tokens=True, clean_up_tokenization_spaces=False)[0]

The generated output

Does anyone have any solutions to suggest here?
