Model Card for Model ID

This model is optimized for plant science by continuing pertaining on over 1.5 million plant science academic articles based on LLaMa-2-13b-base. And it undergoes further instruction tuning to make it follow instructions.

How to Get Started with the Model

from transformers import LlamaTokenizer, LlamaForCausalLM
import torch

tokenizer = LlamaTokenizer.from_pretrained("Xianjun/PLLaMa-13b-instruct")
model = LlamaForCausalLM.from_pretrained("Xianjun/PLLaMa-13b-instruct").half().to("cuda")

instruction = "How to ..."
batch = tokenizer(instruction, return_tensors="pt", add_special_tokens=False).to("cuda")
with torch.no_grad():
    output = model.generate(**batch, max_new_tokens=512, temperature=0.7, do_sample=True)
    response = tokenizer.decode(output[0], skip_special_tokens=True)
