The 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

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.

[
  {
    "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:

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

Pre-training Dataset

• Example dataset

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

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

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

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

Preference Dataset

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

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

[
  {
    "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:

    "query": "input",
    "chosen": "chosen",
    "rejected": "rejected"
  }
}

KTO Dataset

KTO datasets require a extra kto_tag column containing the boolean human feedback.

[
  {
    "instruction": "human instruction (required)",
    "input": "human input (optional)",
    "output": "model response (required)",
    "kto_tag": "human feedback [true/false] (required)"
  }
]

    "query": "input",
    "response": "output",
    "kto_tag": "kto_tag"
  }
}

Multimodal Dataset

• Example dataset

Multimodal datasets require a images column containing the paths to the input images. Currently we only support one image.

[
  {
    "instruction": "human instruction (required)",
    "input": "human input (optional)",
    "output": "model response (required)",
    "images": [
      "image path (required)"
    ]
  }
]

  "columns": {
    "prompt": "instruction",
    "query": "input",
    "response": "output",
    "images": "images"
  }
}

Sharegpt Format

Supervised Fine-Tuning Dataset

• Example dataset

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.

[
  {
    "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:

"dataset_name": {
  "file_name": "data.json",
  "formatting": "sharegpt",
  "columns": {
    "messages": "conversations",
    "system": "system",
    "tools": "tools"
  }
}

Preference Dataset

• Example dataset

Preference datasets in sharegpt format also require a better message in chosen column and a worse message in rejected column.

[
  {
    "conversations": [
      {
        "from": "human",
        "value": "human instruction"
      },
      {
        "from": "gpt",
        "value": "model response"
      },
      {
        "from": "human",
        "value": "human instruction"
      }
    ],
    "chosen": {
      "from": "gpt",
      "value": "chosen answer (required)"
    },
    "rejected": {
      "from": "gpt",
      "value": "rejected answer (required)"
    }
  }
]

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

"dataset_name": {
  "file_name": "data.json",
  "formatting": "sharegpt",
  "ranking": true,
  "columns": {
    "messages": "conversations",
    "chosen": "chosen",
    "rejected": "rejected"
  }
}

OpenAI Format

The openai format is simply a special case of the sharegpt format, where the first message may be a system prompt.

[
  {
    "messages": [
      {
        "role": "system",
        "content": "system prompt (optional)"
      },
      {
        "role": "user",
        "content": "human instruction"
      },
      {
        "role": "assistant",
        "content": "model response"
      }
    ]
  }
]

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

"dataset_name": {
  "file_name": "data.json",
  "formatting": "sharegpt",
  "columns": {
    "messages": "messages"
  },
  "tags": {
    "role_tag": "role",
    "content_tag": "content",
    "user_tag": "user",
    "assistant_tag": "assistant",
    "system_tag": "system"
  }
}

The KTO datasets and multimodal datasets in sharegpt format are similar to the alpaca format.

Pre-training datasets are incompatible with the sharegpt format.
