LLMs Explained,
StableLM
StableLM is an open-source large language model launched by Stability AI. The initial version of the model, with 3 billion and 7 billion parameters, has been released. The larger versions of 15 billion and 65 billion will be made available in the near future. This model is accessible to developers for both commercial and research use.

Model Details
StableLM-Tuned-Alpha models are auto-regressive language models based on the NeoX transformer architecture. Fine-tuned checkpoints (StableLM-Tuned-Alpha) are licensed under the Non-Commercial Creative Commons license, in line with the original non-commercial license specified by Stanford Alpaca.
Model highlights
StableLM is trained using a novel experimental dataset derived from The Pile, which is significantly larger, containing 1.5 trillion content tokens. Despite its relatively smaller size of 3 to 7 billion parameters (in contrast to GPT-3's 175 billion parameters), StableLM demonstrates remarkably high performance in conversational and coding tasks. The vastness and diversity of the dataset contribute to the model's effectiveness in these domains, showcasing its ability to excel despite its parameter limitations.
- As part of their proof-of-concept, the researchers conducted fine-tuning on the model using Stanford Alpaca's procedure. This involved utilizing a combination of five recently curated datasets specifically designed for conversational agents, namely Stanford's Alpaca, Nomic-AI's gpt4all, RyokoAI's ShareGPT52K datasets, Databricks labs' Dolly, and Anthropic's HH. The resulting models, referred to as StableLM-Tuned-Alpha, will be made publicly available by the researchers.
Training Details
Training data
Models are fine-tuned on a combination of five datasets: Alpaca, GPT4All Prompt Generations, Anthropic HH, DataBricks Dolly, closed QA, generation, information extraction, open QA and summarization; and ShareGPT Vicuna.
Training infrastructure
Models are learned via supervised fine-tuning on the aforementioned datasets, trained in mixed-precision (FP16), and optimized with AdamW. The publishers outline the hyperparameters as shown in the table below.
Model Types
StableLM has released two architecture variations with varying numbers of parameters. Here's a brief explanation of each of them:
| Parameters | Batch Size | Learning Rate | Betas |
| 3B | 256 | 2e-5 | (0.9, 0.99) |
| 7B | 128 | 2e-5 | (0.9, 0.99) |
Business Applications
The model can be used in various business applications that require natural language processing (NLP) capabilities, such as chatbots, virtual assistants, and sentiment analysis.
| Use Case | Description |
| Customer Service | Model can be used to understand customer queries and respond to them accurately and efficiently, reducing the need for human intervention. |

Limitations
Bias
While the inclusion of the mentioned datasets assists in guiding the base language models towards more socially acceptable text distributions, it is important to note that fine-tuning alone cannot completely eliminate biases and toxic elements. Therefore, users are encouraged to remain vigilant regarding potential issues that may arise in the generated responses. It is crucial to exercise human judgment and refrain from regarding model outputs as infallible or definitive sources of truth. Responsible usage is strongly advised.
