2. Normalization: Regex-based whitespace cleaning and token normalization.
3. Tokenization: Model-specific subword tokenization with a max sequence length of 512 tokens.

Usage Instructions

To utilize this model for inference, use the following snippet:

from transformers import AutoTokenizer, AutoModelForCausalLM

checkpoint = "singtan/my-llm-finetuned-pdf"
tokenizer = AutoTokenizer.from_pretrained(checkpoint)
model = AutoModelForCausalLM.from_pretrained(checkpoint)

prompt = "Insert your context here"
inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(**inputs, max_length=150)
print(tokenizer.decode(outputs[0]))
