How to use from
SGLang
Install from pip and serve model
# Install SGLang from pip:
pip install sglang
# Start the SGLang server:
python3 -m sglang.launch_server \
    --model-path "Xianjun/Quokka-7b-instruct" \
    --host 0.0.0.0 \
    --port 30000
# Call the server using curl (OpenAI-compatible API):
curl -X POST "http://localhost:30000/v1/completions" \
	-H "Content-Type: application/json" \
	--data '{
		"model": "Xianjun/Quokka-7b-instruct",
		"prompt": "Once upon a time,",
		"max_tokens": 512,
		"temperature": 0.5
	}'
Use Docker images
docker run --gpus all \
    --shm-size 32g \
    -p 30000:30000 \
    -v ~/.cache/huggingface:/root/.cache/huggingface \
    --env "HF_TOKEN=<secret>" \
    --ipc=host \

Model Card for Model ID

This model is optimized for Material Science by continuing pertaining on over 1 million Material science academic articles based on LLaMa-2-7b. And further finetuned on materials science instructions.

  • Developed by: [UCSB]

  • Language(s) (NLP): [More Information Needed]

  • License: [More Information Needed]

  • Finetuned from model [optional]: [LLaMa-2]

  • Paper [optional]: [https://arxiv.org/pdf/2401.01089.pdf]

  • Demo [optional]: [More Information Needed]

How to Get Started with the Model

from transformers import LlamaTokenizer, LlamaForCausalLM
import torch

tokenizer = LlamaTokenizer.from_pretrained("Xianjun/Quokka-7b-instruct ")
model = LlamaForCausalLM.from_pretrained("Xianjun/Quokka-7b-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)
