PULI-LlumiX-Llama-3.1 8B base (8.03B billion parameter)

• Trained with LLaMA-Factory github
• The Llama 3.1 8B Instruct model were continual pretrained on Hungarian dataset

Dataset for continued pretraining

• Hungarian (8.7 billion words): documents (763K) that exceed 5000 words in length + Hungarian Wikipedia and news
• English: Long Context QA (1 billion words), BookSum (42 million words)

Limitations

• max_seq_length = 16 384
• bfloat16

Usage with pipeline

from transformers import pipeline, LlamaForCausalLM, AutoTokenizer

model = LlamaForCausalLM.from_pretrained("NYTK/PULI-LlumiX-Llama-3.1")
tokenizer = AutoTokenizer.from_pretrained("NYTK/PULI-LlumiX-Llama-3.1")
prompt = "Elmesélek egy történetet a nyelvtechnológiáról."
generator = pipeline(task="text-generation", model=model, tokenizer=tokenizer, device=0)

print(generator(prompt, max_new_tokens=30)[0]["generated_text"])

Since the model was continuously pre-trained from Llama 3.1 8B Instruct, it can be used as a chat model.

import torch
from transformers import pipeline

model_id = "NYTK/PULI-LlumiX-Llama-3.1"
pipe = pipeline(
    "text-generation",
    model=model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto",
)
messages = [
    {"role": "system", "content": "You are a helpful assistant"},
    {"role": "user", "content": "Mit gondolsz a nyelvtechnológiáról?"},
]
outputs = pipe(
    messages,
    max_new_tokens=256,
)
print(outputs[0]["generated_text"][-1])
