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。所有合成训练数据都使用微软 Azure 内容过滤器进行审核。

用例

Orca 2 是一个有帮助的助手，它可以帮助您完成各种任务，例如基于您提供的数据进行推理、阅读理解、解决数学问题以及文本摘要。

该模型旨在特别擅长推理。

微软研究院希望该模型能够促进对更小语言模型的开发、评估和对齐进行更多研究。

微软研究院发表的论文，Orca 2：教小型语言模型如何推理

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 https://127.0.0.1:11434/api/generate -d '{
  "model": "orca2",
  "prompt":"Why is the sky blue?"
 }'
```
