模型架构

该模型是一个解码器 Transformer，类似于 LLaMA (Touvron 等人，2023 年) 架构，但做了以下修改

参数	隐藏尺寸	层数	头数	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) 的方法。
分词器：我们使用了一个经过修改的 GPTNeoX 分词器。NeoX。我们添加了特殊标记来训练填充中间 (FIM) 功能，如 <FIM_PREFIX> 和 <FIM_SUFFIX> 以及其他特殊标记。

训练

训练数据集

数据集由在 HuggingFace Hub 上提供的过滤后的开源大型数据集混合组成：Falcon RefinedWeb 提取 (Penedo 等人，2023 年)，以及 CommitPackFT 和 Github Issues (BigCode.，2023 年) 和 StarCoder (Li 等人，2023 年)。我们还用来自数学领域的数据补充了我们的训练 (Azerbayev, Zhangir 等人，2023 年和 Yu, Longhui 等人，2023 年)。

训练的前 18 种编程语言：- 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特定微调的基础基模型。开发人员必须评估和微调模型，使其在后续应用中安全地执行。

限制和偏差

作为基模型，该模型可能会表现出不可靠、不安全或其他不希望有的行为，这些行为必须在部署之前通过评估和微调来纠正。预训练数据集可能包含攻击性或不适当的内容，即使在应用数据清理过滤器之后也是如此，这些内容可能会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谨慎行事。如果模型不适合您的应用，或者用于可能对他人造成故意或无意伤害的任何应用，请不要使用它们。

### 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.
