# StableLM-Base-Alpha |
|
|
|
📢 **DISCLAIMER**: The StableLM-Base-Alpha models have been superseded. Find the latest versions in the Stable LM Collection [here](https://huggingface.co/collections/stabilityai/stable-lm-650852cfd55dd4e15cdcb30a). |
|
|
|
## Model Description |
|
|
|
`StableLM-Base-Alpha` is a suite of 3B and 7B parameter decoder-only language models pre-trained on a diverse collection of English datasets with a sequence length of 4096 to push beyond the context window limitations of existing open-source language models. |
|
|
|
## Usage |
|
|
|
Get started generating text with `StableLM-Base-Alpha` by using the following code snippet: |
|
|
|
```python |
|
from transformers import AutoModelForCausalLM, AutoTokenizer |
|
|
|
tokenizer = AutoTokenizer.from_pretrained("StabilityAI/stablelm-base-alpha-7b") |
|
model = AutoModelForCausalLM.from_pretrained("StabilityAI/stablelm-base-alpha-7b") |
|
model.half().cuda() |
|
|
|
inputs = tokenizer("What's your mood today?", return_tensors="pt").to("cuda") |
|
tokens = model.generate( |
|
**inputs, |
|
max_new_tokens=64, |
|
temperature=0.7, |
|
do_sample=True, |
|
) |
|
print(tokenizer.decode(tokens[0], skip_special_tokens=True)) |
|
``` |
|
|
|

### Training Dataset |
|
|
|
`StableLM-Base-Alpha` is pre-trained on a new experimental dataset built atop [The Pile](https://huggingface.co/datasets/EleutherAI/the_pile) and is threes times larger at approximately 1.5T tokens. |
|
|
|
### Training Procedure |
|
|
|
Models are pre-trained on the aforementioned dataset in mixed-precision (FP16), optimized with Adam, and trained using the NeoX tokenizer with a vocabulary size of 50,257. We outline the complete hyperparameters choices in the project's [GitHub repository](https://github.com/Stability-AI/StableLM/blob/main/configs/stablelm-base-alpha-7b.yaml). |
|
|
|
## Use and Limitations |
|
|
|
### Intended Use |
|
|
|
These models are intended to be used by all individuals as foundational models for application-specific fine-tuning without strict limitations on commercial use. |
|
|
|
### Limitations and bias |
|
|
|
The pre-training dataset may have contained offensive or inappropriate content even after applying data cleansing filters which can be reflected in the model generated text. We recommend users exercise reasonable caution when using these models in production systems. Do not use the models for any applications that may cause harm or distress to individuals or groups. |
