Model Details
Model Description
DeciLM-7B-instruct is a derivative of the recently released DeciLM-7B language model, a pre-trained, high-efficiency generative text model with 7 billion parameters. DeciLM-7B-instruct is one the best 7B instruct models obtained using simple LoRA fine-tuning, without relying on preference optimization techniques such as RLHF and DPO.
- Developed by: Deci
- Model type: DeciLM is an auto-regressive language model using an optimized transformer decoder architecture that includes variable Grouped-Query Attention.
- Language(s) (NLP): English
- License: Apache 2.0
Model Architecture
| Parameters | Layers | Heads | Sequence Length | GQA num_key_value_heads* |
|---|---|---|---|---|
| 7.04 billion | 32 | 32 | 8192 | Variable |
*AutoNAC was employed to optimize the selection of the GQA num_key_value_heads for each model layer.

Uses
The model is intended for commercial and research use in English.
How to Get Started with the Model
Use the code below to get started with the model.
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM, BitsAndBytesConfig, pipeline
model_name = "Deci/DeciLM-7B-instruct"
device = "cuda" # for GPU usage or "cpu" for CPU usage
quantize = False # Optional. Useful for GPUs with less than 24GB memory
if quantize:
dtype_kwargs = dict(quantization_config=BitsAndBytesConfig(
load_in_4bit=True,
bnb_4bit_compute_dtype=torch.bfloat16
))
else:
dtype_kwargs = dict(torch_dtype="auto")
model = AutoModelForCausalLM.from_pretrained(
model_name,
device_map="auto",
trust_remote_code=True,
**dtype_kwargs
)
tokenizer = AutoTokenizer.from_pretrained(model_name)
tokenizer.pad_token = tokenizer.eos_token
deci_generator = pipeline("text-generation",
model=model,
tokenizer=tokenizer,
temperature=0.1,
device_map="auto",
max_length=4096,
return_full_text=False)
system_prompt = "You are an AI assistant that follows instruction extremely well. Help as much as you can."
user_prompt = "How do I make the most delicious pancakes the world has ever tasted?"
prompt = tokenizer.apply_chat_template([
{"role": "system", "content": system_prompt},
{"role": "user", "content": user_prompt},
], tokenize=False, add_generation_prompt=True)
response = deci_generator(prompt)[0]['generated_text']
print(prompt + response)

Ethical Considerations and Limitations
DeciLM-7B-instruct is a new technology that comes with inherent risks associated with its use. The testing conducted so far has been primarily in English and does not encompass all possible scenarios. Like those of all large language models, DeciLM-7B's outputs are unpredictable, and the model may generate responses that are inaccurate, biased, or otherwise objectionable. Consequently, developers planning to use DeciLM-7B should undertake thorough safety testing and tuning designed explicitly for their intended applications of the model before deployment.
