Orca 2 模型由微軟研究院開發。它們基於 Meta 的 Llama 2 進行微調，使用合成數據集，該數據集旨在增強小型模型的推理能力。所有合成訓練數據均使用 Microsoft Azure 內容過濾器進行審核。

使用案例

Orca 2 是一個有用的助手，可以在諸如根據給定數據進行推理、閱讀理解、數學問題解決和文本摘要等任務中提供答案。

此模型旨在於推理方面表現出色。

微軟研究院開發此模型的目的是為了鼓勵進一步研究小型語言模型的開發、評估和對齊。

微軟研究院發表的論文，Orca 2：教導小型語言模型如何推理

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