Model

You can download our base 7B model from this link and our chat 7B model from this link.

Inference

You can use the following code to run inference with the model. The model is saved under './model/' directory. Change the model directory accordingly or use the Huggingface link.

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM, pipeline

torch.backends.cuda.enable_mem_efficient_sdp(False)
torch.backends.cuda.enable_flash_sdp(False)


model_name = 'moxin-org/moxin-llm-7b'
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
        model_name,
        torch_dtype=torch.bfloat16,
        device_map="auto",
        trust_remote_code=True,
    )

pipe = pipeline(
    "text-generation",
    model=model,
    tokenizer = tokenizer,
    torch_dtype=torch.bfloat16,
    device_map="auto"
)

prompt = "Can you explain the concept of regularization in machine learning?"

sequences = pipe(
    prompt,
    do_sample=True,
    max_new_tokens=1000,
    temperature=0.7,
    top_k=50,
    top_p=0.95,
    num_return_sequences=1,
)
print(sequences[0]['generated_text'])

Evaluation

We test the performance of our model with lm-evaluation-harness. The evaluation results on common datasets are shown below. We test on AI2 Reasoning Challenge (25-shot), HellaSwag (10-shot), MMLU (5-shot), and Winogrande (5-shot). We release the Moxin-7B-finetuned as our base model. We further finetune our base model on Tulu v2 to obtain our chat model.
