自述文件

Orca 2 模型由微软研究院构建。它们是在 Meta 的 Llama 2 上使用合成数据集进行微调的，该数据集旨在增强小型模型的推理能力。所有合成训练数据均使用 Microsoft Azure 内容过滤器进行审核。

用例

Orca 2 是一位有用的助手，可以在各种任务中提供答案，例如推理给定数据、阅读理解、数学问题解决和文本摘要。

该模型的设计使其特别擅长推理。

微软研究院推出此模型的目的是为了鼓励进一步研究小型语言模型的开发、评估和对齐。

Orca 2 models are built by Microsoft Research. They are fine-tuned on Meta's Llama 2 using a synthetic dataset that was created to enhance the small model's reasoning abilities. All synthetic training data was moderated using Microsoft Azure content filters.

### Use case

Orca 2 is a helpful assistant, and provides an answer in tasks such as reasoning over your given data, reading comprehension, math problem solving and text summarization.

The model is designed to excel particularly in reasoning.

Microsoft Research's intended purpose for this model is to encourage further research on the development, evaluation, and alignment of smaller language models.

### CLI

7 billion parameter model:

```
ollama run orca2
```

13 billion parameter model:

```
ollama run orca2:13b
```

### API

Example:

```bash
curl -X POST http://localhost:11434/api/generate -d '{
  "model": "orca2",
  "prompt":"Why is the sky blue?"
 }'
```
