Constraints

• Import from OBS: The size of a single file or compressed package cannot exceed 20 GB. If multiple files are imported, the total file size cannot exceed 20 GB.
• Local import: The size of a single file cannot exceed 1 GB, and the number of files cannot exceed 20.
• File encoding: All JSONL format files must use UTF-8 encoding.

Format Requirement

File formats: JSONL

Format description: JSONL is a structured, lightweight text file format. Its core rule is that every line in the file must be an independent, valid, and complete JSON object.

Dataset logical specifications: To accommodate the conventions of different open-source communities, this data type supports three mainstream logical specifications: standard format, Alpaca format, and ShareGPT format.

Standard Format

This specification follows industry-standard conventions and records conversations using a message sequence, offering exceptionally high versatility and compatibility.

Data format example

To make the field hierarchy clearer, the single-line JSONL data has been expanded.

{
  "meta": {
    "conversation_id": "conversation_123",
    "user_id": "user_456",
    "timestamp": "2026-05-29T10:00:00Z",
    "domain": "math_tutoring"
  },
  "messages": [
    {
      "role": "user",
      "content": "Please help me solve the equation 2x + 5 = 13."
    },
    {
      "role": "assistant",
      "content": "<think>This is a linear equation in one variable. I need to move the constant term to the right side and then divide by the coefficient.</think>\nSure, let's solve this equation: 2x + 5 = 13. Subtracting 5 from both sides gives 2x = 8, so x = 4."
    },
    {
      "role": "user",
      "content": "What about 3(x - 2) = 9?"
    },
    {
      "role": "assistant",
      "content": "<think>This equation contains parentheses. I can either expand them first or divide both sides by 3 directly.</think>\nYou can solve it like this: dividing both sides by 3 gives x - 2 = 3, so x = 5."
    },
    {
      "role": "user",
      "content": "Thanks, I understand now."
    },
    {
      "role": "assistant",
      "content": "You're welcome! Feel free to ask if you have any more questions."
    }
  ]
}

Field specifications

The table below shows an example of each entry (line) in the JSONL file.

Alpaca Format

This specification originates from the Stanford Alpaca community project. It breaks down single interactions or multi-turn dialogues with history into clear instructions (instruction), supplementary context (input), and standard output (output). Its flat structure makes it easy to read and suitable for rapid fine-tuning.

Data format example

To make the field hierarchy clearer, the single-line JSONL data has been expanded.

{
  "system": "You are an AI teaching assistant proficient in elementary mathematics.",
"instruction": "Please help me solve the equation 2x + 5 = 13.",
  "input": "",
  "output": "<think>This is a linear equation in one variable. I need to move the constant term to the right side and then divide by the coefficient.</think>\nSure, let's solve this equation: 2x + 5 = 13. Subtracting 5 from both sides gives 2x = 8, so x = 4."
  "history": [
    [
      "Hello, can you help me tutor math?",
      "Of course! Feel free to ask any math questions you have."
    ]
  ]
}

ShareGPT Format

This specification is widely used across various open-source frameworks. It linearly reproduces the multi-turn alternating interaction process between humans and AI through a centralized conversation list (conversations), featuring a compact structure and exceptional extensibility.

Data format example

To make the field hierarchy clearer, the single-line JSONL data has been expanded.

{
  "system_prompt": "Role: Mathematics Tutoring Expert",
  "conversations": [
    {
      "from": "human",
      "value": "Please help me solve the equation 2x + 5 = 13."
    },
    {
      "from": "gpt",
      "value": "<think>Transpose terms, simplify, and solve.</think>\nSolving the equation gives 2x = 8, so x = 4."
    }
  ]
}
