位置嵌入: 旋转位置嵌入 (Su 等人，2021 年) 应用于前 25% 的头嵌入维度，以改进吞吐量，遵循 Black 等人（2022 年）。
分词器: 我们使用的是 GPTNeoX 分词器的修改版本。NeoX。我们添加了特殊标记以训练中间填充 (FIM) 功能，如 <FIM_PREFIX> 和 <FIM_SUFFIX> 以及其他特殊标记。

训练

训练数据集

该数据集包含从 HuggingFace Hub 上的开源大型数据集混合而成的过滤数据：Falcon RefinedWeb 提取 (Penedo 等人，2023 年)，以及 CommitPackFT 和 Github Issues (BigCode., 2023) 和 StarCoder (Li 等人，2023 年)。我们还使用来自数学领域的数据补充训练 (Azerbayev，Zhangir 等人，2023 年以及 Yu，Longhui 等人，2023 年)。

训练的 18 种主要编程语言：- C - CPP - Java - JavaScript - CSS - Go - HTML - Ruby - Rust - Markdown - Shell - Php - Sql - R - Typescript - Python - Jupyter-Clean - RestructuredText

使用和限制

预期用途

该模型旨在用作应用程序特定微调的基础模型。开发人员必须评估并微调模型，以确保其在后续应用程序中安全运行。

限制和偏差

作为一个基础模型，该模型可能会表现出不可靠、不安全或其他不良行为，必须在部署之前通过评估和微调进行更正。预训练数据集可能包含冒犯性或不当内容，即使在应用数据清洗过滤器之后也是如此，这可能会反映在模型生成的文本中。建议用户在生产系统中使用这些模型时要谨慎。如果模型不适合您的应用程序，或用于可能对他人造成有意或无意伤害的任何应用程序，请勿使用这些模型。

### Model Architecture

The model is a decoder-only transformer similar to the LLaMA ([Touvron et al., 2023](https://arxiv.org/abs/2307.09288)) architecture with the following modifications:

| Parameters     | Hidden Size | Layers | Heads | Sequence Length |
|----------------|-------------|--------|-------|-----------------|
| 2,796,431,360  | 2560        | 32     | 32    | 16384            |

* **Position Embeddings**: Rotary Position Embeddings ([Su et al., 2021](https://arxiv.org/abs/2104.09864)) applied to the first 25% of head embedding dimensions for improved throughput following [Black et al. (2022)](https://arxiv.org/pdf/2204.06745.pdf).
* **Tokenizer**: We use a modified version of the GPTNeoX Tokenizer.[`NeoX`](https://github.com/EleutherAI/gpt-neox). We add special tokens to train for Fill in the Middle (FIM) capabilities like `<FIM_PREFIX>` and `<FIM_SUFFIX>` along with other special tokens.

## Training

### Training Dataset

The dataset is comprised of a filtered mixture of open-source large-scale datasets available on the [HuggingFace Hub](https://hugging-face.cn/datasets): Falcon RefinedWeb extract ([Penedo et al., 2023](https://hugging-face.cn/datasets/tiiuae/falcon-refinedweb)), along with [CommitPackFT](https://hugging-face.cn/datasets/bigcode/commitpackft) and [Github Issues](https://hugging-face.cn/datasets/bigcode/the-stack-github-issues) (BigCode., 2023), and StarCoder ([Li et al., 2023](https://arxiv.org/abs/2305.06161)). We further supplement our training with data from mathematical domains ([Azerbayev, Zhangir, et al., 2023](https://arxiv.org/abs/2310.10631) and, [Yu, Longhui, et al., 2023](https://arxiv.org/abs/2309.12284)).

## 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.

### 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.
