Example Code
Here is an example of how to use the Llama-2-Ko model with the Hugging Face Transformers library:
from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline
model = AutoModelForCausalLM.from_pretrained("beomi/llama-2-ko-70b")
tokenizer = AutoTokenizer.from_pretrained("beomi/llama-2-ko-70b")
pipe = pipeline("text-generation", model=model, tokenizer=tokenizer)
def generate_text(prompt):
output = pipe(prompt, max_new_tokens=300, top_p=0.95, do_sample=True)
return output[0]["generated_text"]
print(generate_text("### Title: Hello World\n\n### Contents:"))
Note that this is just an example, and you will need to modify the code to suit your specific use case.
Performance
The Llama-2-Ko model is a powerful tool for generating human-like text. It’s capable of generating high-quality text based on a given prompt.
Speed
How fast can the Llama-2-Ko model process text? With its optimized transformer architecture, it can handle large amounts of text data quickly. For example, it can generate text with a maximum of 300 new tokens in a single pass.
Accuracy
But how accurate is the Llama-2-Ko model? Its performance in text generation tasks is remarkable, thanks to its expanded vocabulary and training on a Korean corpus. It can understand and respond to a wide range of texts, from simple sentences to more complex passages.
Efficiency
What about its efficiency? The Llama-2-Ko model is designed to be efficient, requiring at least 74GB of VRAM to run with 8-bit inference and at least 150GB of VRAM to run with bf16 inference. This makes it suitable for use with high-end GPUs like the RTX 3090/4090 or A100/H100.
Limitations
The Llama-2-Ko model is a powerful tool, but it’s not perfect. Let’s take a closer look at some of its limitations.
Limited Context Understanding
While the Llama-2-Ko model can process a large amount of text, it may struggle to fully understand the context of a given prompt. This can lead to responses that don’t quite fit the conversation or topic.
Lack of Common Sense
The Llama-2-Ko model is a large language model, but it doesn’t have the same level of common sense as a human. It may not always understand the implications of a particular action or decision.
Limited Domain Knowledge
While the Llama-2-Ko model has been trained on a vast amount of text data, its knowledge in specific domains may be limited. It may not always have the most up-to-date information or expertise in a particular area.
Tokenization Limitations
The Llama-2-Ko model uses a Sentencepiece BPE tokenization method, which can lead to limitations in tokenizing certain words or phrases. For example, it may not always be able to correctly tokenize Korean text.
Inference Requirements
The Llama-2-Ko model requires significant computational resources to run, particularly for 8-bit and bf16 inference. This can make it difficult to use on lower-end hardware.
Training Data Limitations
While the Llama-2-Ko model has been trained on a large dataset, it may not always reflect the diversity of human experience or perspectives. This can lead to biases in its responses.
Vocabulary Expansion
The Llama-2-Ko model has a vocabulary size of 46,592, which is larger than its predecessor, but still limited. This can lead to difficulties in generating text that uses rare or specialized vocabulary.
Fine-Tuning Limitations
The Llama-2-Ko model is not fine-tuned with an Instruction dataset, which can make it less optimal for certain tasks or prompts.
These limitations are important to keep in mind when using the Llama-2-Ko model, and we’re working to address them in future updates.
