The [dataset_info.json](dataset_info.json) contains all available datasets. If you are using a custom dataset, please **make sure** to add a *dataset description* in `dataset_info.json` and specify `dataset: dataset_name` before training to use it.

Currently we support datasets in **alpaca** and **sharegpt** format.

## Alpaca Format

### Supervised Fine-Tuning Dataset

* [Example dataset](alpaca_en_demo.json)

In supervised fine-tuning, the `instruction` column will be concatenated with the `input` column and used as the human prompt, then the human prompt would be `instruction\ninput`. The `output` column represents the model response.

The `system` column will be used as the system prompt if specified.

The `history` column is a list consisting of string tuples representing prompt-response pairs in the history messages. Note that the responses in the history **will also be learned by the model** in supervised fine-tuning.

```json
[
  {
    "instruction": "human instruction (required)",
    "input": "human input (optional)",
    "output": "model response (required)",
    "system": "system prompt (optional)",
    "history": [
      ["human instruction in the first round (optional)", "model response in the first round (optional)"],
      ["human instruction in the second round (optional)", "model response in the second round (optional)"]
    ]
  }
]
```

Regarding the above dataset, the *dataset description* in `dataset_info.json` should be:

```json
"dataset_name": {
  "file_name": "data.json",
  "columns": {
    "prompt": "instruction",
    "query": "input",
    "response": "output",
    "system": "system",
    "history": "history"
  }
}
```

### Pre-training Dataset

- [Example dataset](c4_demo.json)

In pre-training, only the `text` column will be used for model learning.

```json
[
  {"text": "document"},
  {"text": "document"}
]
```

Regarding the above dataset, the *dataset description* in `dataset_info.json` should be:

```json
"dataset_name": {
  "file_name": "data.json",
  "columns": {
    "prompt": "text"
  }
}
```

### Preference Dataset

Preference datasets are used for reward modeling, DPO training, ORPO and SimPO training.

It requires a better response in `chosen` column and a worse response in `rejected` column.

```json
[
  {
    "instruction": "human instruction (required)",
    "input": "human input (optional)",
    "chosen": "chosen answer (required)",
    "rejected": "rejected answer (required)"
  }
]
```

Regarding the above dataset, the *dataset description* in `dataset_info.json` should be:

```json

  "file_name": "data.json",
  "ranking": true,
  "columns": {
    "prompt": "instruction",
    "query": "input",
    "chosen": "chosen",
    "rejected": "rejected"
  }
}
```

### KTO Dataset

An additional column `kto_tag` is required. Please refer to the [sharegpt](#sharegpt-format) format for details.

### Multimodal Image Dataset

An additional column `images` is required. Please refer to the [sharegpt](#sharegpt-format) format for details.

An additional column `videos` is required. Please refer to the [sharegpt](#sharegpt-format) format for details.

## Sharegpt Format

### Supervised Fine-Tuning Dataset

- [Example dataset](glaive_toolcall_en_demo.json)

Compared to the alpaca format, the sharegpt format allows the datasets have **more roles**, such as human, gpt, observation and function. They are presented in a list of objects in the `conversations` column.

Note that the human and observation should appear in odd positions, while gpt and function should appear in even positions.

```json
[
  {
    "conversations": [
      {
        "from": "human",
        "value": "human instruction"
      },
      {
        "from": "function_call",
        "value": "tool arguments"
      },
      {
        "from": "observation",
        "value": "tool result"
      },
      {
        "from": "gpt",
        "value": "model response"
      }
    ],
    "system": "system prompt (optional)",
    "tools": "tool description (optional)"
  }
]
```

Regarding the above dataset, the *dataset description* in `dataset_info.json` should be:

```json
"dataset_name": {

  "formatting": "sharegpt",
  "columns": {
    "messages": "conversations",
    "system": "system",
