Stable LM 2 12B

Model Description

Stable LM 2 12B is a 12.1 billion parameter decoder-only language model pre-trained on 2 trillion tokens of diverse multilingual and code datasets for two epochs.

Please note: For commercial use, please refer to https://stability.ai/license.

Usage

NOTE: This model requires transformers>=4.40.0

Get started generating text with Stable LM 2 12B by using the following code snippet:

from transformers import AutoModelForCausalLM, AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("stabilityai/stablelm-2-12b")
model = AutoModelForCausalLM.from_pretrained(
  "stabilityai/stablelm-2-12b",
  torch_dtype="auto",
)
model.cuda()
inputs = tokenizer("The weather is always wonderful", return_tensors="pt").to(model.device)
tokens = model.generate(
  **inputs,
  max_new_tokens=64,
  temperature=0.70,
  top_p=0.95,
  do_sample=True,
)
print(tokenizer.decode(tokens[0], skip_special_tokens=True))

Model Architecture

The model is a decoder-only transformer with the following architecture:

• Position Embeddings: Rotary Position Embeddings (Su et al., 2021) applied to the first 25% of head embedding dimensions for improved throughput following Black et al. (2022).
• Parallel Layers: Parallel attention and feed-forward residual layers with a single input LayerNorm (Wang, 2021).
• Normalization: LayerNorm (Ba et al., 2016) without biases. Furthermore, we apply per-head QK normalization (Dehghani et al., 2023, Wortsman et al., 2023).
• Biases: We remove all bias terms from the feed-forward networks and grouped-query self-attention layers.
• Tokenizer: We use Arcade100k, a BPE tokenizer extended from OpenAI's tiktoken.cl100k_base. We split digits into individual tokens following findings by Liu & Low (2023).

Training

Training Dataset

The dataset is comprised of a filtered mixture of open-source large-scale datasets available on the HuggingFace Hub: Falcon RefinedWeb extract (Penedo et al., 2023), RedPajama-Data (Together Computer., 2023) and The Pile (Gao et al., 2020) both without the Books3 subset, and StarCoder (Li et al., 2023). We further supplement our training with multi-lingual data from CulturaX (Nguyen et al., 2023) and, in particular, from its OSCAR corpora, as well as restructured data in the style of Yuan & Liu (2022).

• Given the large amount of web data, we recommend fine-tuning the base Stable LM 2 12B for your downstream tasks.

Training Procedure

The model is pre-trained on the aforementioned datasets in bfloat16 precision, optimized with AdamW, and trained using the Arcade100k tokenizer with a vocabulary size of 100,352. We outline the complete hyperparameters choices in the project's GitHub repository - config*.

Training Infrastructure

• Hardware: Stable LM 2 12B was trained on the Stability AI cluster across 384 NVIDIA H100 GPUs (AWS P5 instances).

• Software: We use a fork of gpt-neox (EleutherAI, 2021), train under 2D parallelism (Data and Tensor Parallel) with ZeRO-1 (Rajbhandari et al., 2019), and rely on flash-attention as well as SwiGLU and Rotary Embedding kernels from FlashAttention-2 (Dao et al., 2023)

Use and Limitations

Intended Use

The model is intended to be used as a foundational base model for application-specific fine-tuning. Developers must evaluate and fine-tune the model for safe performance in downstream applications. For commercial use, please refer to https://stability.ai/membership.

Limitations and Bias

​ As a base model, this model may exhibit unreliable, unsafe, or other undesirable behaviors that must be corrected through evaluation and fine-tuning prior to deployment. 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 that users exercise caution when using these models in production systems. Do not use the models if they are unsuitable for your application, or for any applications that may cause deliberate or unintentional harm to others.
