# Model Card for `dlite-v1-124m` |
|
|
|
<!-- Provide a quick summary of what the model is/does. --> |
|
|
|
AI Squared's `dlite-v1-124m` ([blog post](https://medium.com/ai-squared/introducing-dlite-a-lightweight-chatgpt-like-model-based-on-dolly-deaa49402a1f)) is a large language |
|
model which is derived from OpenAI's smallest [GPT-2](https://huggingface.co/gpt2) model and fine-tuned on a single T4 GPU on a corpus of 50k records |
|
([Stanford Alpaca](https://crfm.stanford.edu/2023/03/13/alpaca.html)) to help it exhibit chat-based capabilities. |
|
|
|
While `dlite-v1-124m` is **not a state-of-the-art model**, we believe that the level of interactivity that can be achieved on such a small model that is trained so cheaply |
|
is important to showcase, as it continues to demonstrate that creating powerful AI capabilities may be much more accessible than previously thought. |

## Bias, Risks, and Limitations |
|
|
|
<!-- This section is meant to convey both technical and sociotechnical limitations. --> |
|
|
|
**`dlite-v1-124m` is not a state-of-the-art language model.** `dlite-v1-124m` is an experimental technology and is not designed for use in any |
|
environment other than for research purposes. Furthermore, the model can sometimes exhibit undesired behaviors. Some of these behaviors include, |
|
but are not limited to: factual inaccuracies, biases, offensive responses, toxicity, and hallucinations. |
|
Just as with any other LLM, we advise users of this technology to exercise good judgment when applying this technology. |
|
|
|
|
|
## Usage |
|
|
|
To use the model with the `transformers` library on a machine with GPUs, first make sure you have the `transformers` and `accelerate` libraries installed. |
|
From your terminal, run: |
|
|
|
```python |
|
pip install "accelerate>=0.16.0,<1" "transformers[torch]>=4.28.1,<5" "torch>=1.13.1,<2" |
|
``` |
|
|
|
The instruction following pipeline can be loaded using the `pipeline` function as shown below. This loads a custom `InstructionTextGenerationPipeline` |
|
found in the model repo [here](https://huggingface.co/aisquared/dlite-v1-124m/blob/main/instruct_pipeline.py), which is why `trust_remote_code=True` is required. |
|
Including `torch_dtype=torch.bfloat16` is generally recommended if this type is supported in order to reduce memory usage. It does not appear to impact output quality. |
|
It is also fine to remove it if there is sufficient memory. |
|
|
|
```python |
|
from transformers import pipeline |
|
import torch |
|
|
|
generate_text = pipeline(model="aisquared/dlite-v1-124m", torch_dtype=torch.bfloat16, trust_remote_code=True, device_map="auto") |
|
``` |
|
|
|
You can then use the pipeline to answer instructions: |
|
|
|
```python |
|
res = generate_text("Who was George Washington?") |
|
print(res) |
|
``` |
|
|
|
Alternatively, if you prefer to not use `trust_remote_code=True` you can download [instruct_pipeline.py](https://huggingface.co/aisquared/dlite-v1-124m/blob/main/instruct_pipeline.py), |
|
store it alongside your notebook, and construct the pipeline yourself from the loaded model and tokenizer: |
|
|
|
```python |
|
from instruct_pipeline import InstructionTextGenerationPipeline |
|
from transformers import AutoModelForCausalLM, AutoTokenizer |
|
import torch |
|
|
|
tokenizer = AutoTokenizer.from_pretrained("aisquared/dlite-v1-124m", padding_side="left") |
|
model = AutoModelForCausalLM.from_pretrained("aisquared/dlite-v1-124m", device_map="auto", torch_dtype=torch.bfloat16) |
|
|
|
generate_text = InstructionTextGenerationPipeline(model=model, tokenizer=tokenizer) |
|
``` |
|
|
|
### Model Performance Metrics |
|
|
|
We present the results from various model benchmarks on the EleutherAI LLM Evaluation Harness for all models in the DLite family. |
|
Model results are sorted by mean score, ascending, to provide an ordering. These metrics serve to further show that none of the DLite models are |
|
state of the art, but rather further show that chat-like behaviors in LLMs can be trained almost independent of model size. |
