模型架构

该模型是一个仅解码器的 Transformer，类似于 LLaMA (Touvron 等人，2023 年) 架构，但以下方面有所改动

参数	隐藏大小	层数	头部数	序列长度
2,796,431,360	2560	32	32	16384

位置嵌入：旋转位置嵌入 (Su 等人，2021 年) 应用于前 25% 的头部嵌入维度，以提高吞吐量，遵循 Black 等人 (2022 年)。
分词器：我们使用的是 GPTNeoX 分词器的修改版。NeoX。我们在分词器中添加了一些特殊词符，以训练中间填充 (FIM) 功能，例如 <FIM_PREFIX> 和 <FIM_SUFFIX>，以及其他特殊词符。

训练

训练数据集

数据集包含来自 HuggingFace Hub 上公开的大规模数据集的过滤混合：Falcon RefinedWeb 提取 (Penedo 等人，2023 年)，以及 CommitPackFT 和 Github Issues (BigCode.，2023 年)，以及 StarCoder (Li 等人，2023 年)。我们还使用来自数学领域的数据来补充我们的训练 (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

该模型旨在用作特定应用微调的基础基础模型。开发人员必须评估并微调模型，使其在后续应用中安全运行。

限制和偏差

作为基础模型，该模型可能表现出不可靠、不安全或其他不理想的行为，必须通过评估和微调来纠正这些行为，然后再部署。预训练数据集可能包含攻击性或不恰当的内容，即使应用了数据清理过滤器，这些内容也可能反映在模型生成的文本中。我们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，或用于可能对他人造成故意或无意伤害的任何应用，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.
