# Synthetic Data Kit

Tool for generating high-quality synthetic datasets to fine-tune LLMs.

Generate Reasoning Traces, QA Pairs, save them to a fine-tuning format with a simple CLI.

> [Checkout our guide on using the tool to unlock task-specific reasoning in Llama-3 family](https://github.com/meta-llama/synthetic-data-kit/tree/main/use-cases/adding_reasoning_to_llama_3)

# What does Synthetic Data Kit offer? 

Fine-Tuning Large Language Models is easy. There are many mature tools that you can use to fine-tune Llama model family using various post-training techniques.

### Why target data preparation?

Multiple tools support standardized formats. However, most of the times your dataset is not structured in "user", "assistant" threads or in a certain format that plays well with a fine-tuning packages. 

This toolkit simplifies the journey of:

- Using a LLM (vLLM or any local/external API endpoint) to generate examples
- Modular 4 command flow
- Converting your existing files to fine-tuning friendly formats
- Creating synthetic datasets
- Supporting various formats of post-training fine-tuning

# How does Synthetic Data Kit offer it? 

The tool is designed to follow a simple CLI structure with 4 commands:

- `ingest` various file formats
- `create` your fine-tuning format: `QA` pairs, `QA` pairs with CoT, `summary` format
- `curate`: Using Llama as a judge to curate high quality examples. 
- `save-as`: After that you can simply save these to a format that your fine-tuning workflow requires.

You can override any parameter or detail by either using the CLI or overriding the default YAML config.


### Installation

#### From PyPI

```bash
# Create a new environment

conda create -n synthetic-data python=3.10 

conda activate synthetic-data

pip install synthetic-data-kit
```

#### (Alternatively) From Source

```bash
git clone https://github.com/meta-llama/synthetic-data-kit.git
cd synthetic-data-kit
pip install -e .
```

To get an overview of commands type: 

`synthetic-data-kit --help`

### 1. Tool Setup

- The tool expects respective files to be put in named folders.

```bash
# Create directory structure
mkdir -p data/{pdf,html,youtube,docx,ppt,txt,output,generated,cleaned,final}
```

- You also need a LLM backend that you will utilize for generating your dataset, if using vLLM:

```bash
# Start vLLM server
# Note you will need to grab your HF Authentication from: https://huggingface.co/settings/tokens
vllm serve meta-llama/Llama-3.3-70B-Instruct --port 8000
```

### 2. Usage

The flow follows 4 simple steps: `ingest`, `create`, `curate`, `save-as`, please paste your file into the respective folder:

```bash
# Check if your backend is running
synthetic-data-kit system-check

# Parse a document to text
synthetic-data-kit ingest docs/report.pdf
# This will save file to data/output/report.txt

# Generate QA pairs (default)
synthetic-data-kit create data/output/report.txt --type qa

OR 

# Generate Chain of Thought (CoT) reasoning examples
synthetic-data-kit create data/output/report.txt --type cot

# Both of these will save file to data/generated/report_qa_pairs.json

# Filter content based on quality
synthetic-data-kit curate data/generated/report_qa_pairs.json

# Convert to alpaca fine-tuning format and save as HF arrow file
synthetic-data-kit save-as data/cleaned/report_cleaned.json --format alpaca --storage hf
```
## Configuration

The toolkit uses a YAML configuration file (default: `configs/config.yaml`).

Note, this can be overridden via either CLI arguments OR passing a custom YAML file

```yaml
# Example configuration using vLLM
llm:
  provider: "vllm"

vllm:
  api_base: "http://localhost:8000/v1"
  model: "meta-llama/Llama-3.3-70B-Instruct"

generation:
  temperature: 0.7
  chunk_size: 4000
  num_pairs: 25

curate:
  threshold: 7.0
  batch_size: 8
```

or using an API endpoint:

```yaml
# Example configuration using the llama API
llm:
  provider: "api-endpoint"

api-endpoint:
  api_base: "https://api.llama.com/v1"
  api_key: "llama-api-key"
  model: "Llama-4-Maverick-17B-128E-Instruct-FP8"
```

### Customizing Configuration

Create a overriding configuration file and use it with the `-c` flag:

```bash
synthetic-data-kit -c my_config.yaml ingest docs/paper.pdf
```

## Examples

### Processing a PDF Document

```bash
# Ingest PDF
synthetic-data-kit ingest research_paper.pdf

# Generate QA pairs
synthetic-data-kit create data/output/research_paper.txt -n 30 --threshold 8.0

# Curate data
synthetic-data-kit curate data/generated/research_paper_qa_pairs.json -t 8.5

# Save in OpenAI fine-tuning format (JSON)
synthetic-data-kit save-as data/cleaned/research_paper_cleaned.json -f ft

# Save in OpenAI fine-tuning format (HF dataset)
synthetic-data-kit save-as data/cleaned/research_paper_cleaned.json -f ft --storage hf
```

### Processing a YouTube Video

```bash
# Extract transcript
synthetic-data-kit ingest "https://www.youtube.com/watch?v=dQw4w9WgXcQ"

# Generate QA pairs with specific model
synthetic-data-kit create data/output/youtube_dQw4w9WgXcQ.txt
```

### Processing Multiple Files

```bash
# Bash script to process multiple files
for file in data/pdf/*.pdf; do
  filename=$(basename "$file" .pdf)
  
  synthetic-data-kit ingest "$file"
  synthetic-data-kit create "data/output/${filename}.txt" -n 20
  synthetic-data-kit curate "data/generated/${filename}_qa_pairs.json" -t 7.5
  synthetic-data-kit save-as "data/cleaned/${filename}_cleaned.json" -f chatml
done
```

## Advanced Usage

### Custom Prompt Templates

Edit the `prompts` section in your configuration file to customize generation behavior:

```yaml
prompts:
  qa_generation: |
    You are creating question-answer pairs for fine-tuning a legal assistant.
    Focus on technical legal concepts, precedents, and statutory interpretation.
    
    Below is a chunk of text about: {summary}...
    
    Create {num_pairs} high-quality question-answer pairs based ONLY on this text.
    
    Return ONLY valid JSON formatted as:
    [
      {
        "question": "Detailed legal question?",
        "answer": "Precise legal answer."
      },
      ...
    ]
    
    Text:
    ---
    {text}
    ---
```

## Troubleshooting FAQs:

### vLLM Server Issues

- Ensure vLLM is installed: `pip install vllm`
- Start server with: `vllm serve <model_name> --port 8000`
- Check connection: `synthetic-data-kit system-check`

### Memory Issues

If you encounter CUDA out of memory errors:
- Use a smaller model
- Reduce batch size in config
- Start vLLM with `--gpu-memory-utilization 0.85`

### JSON Parsing Issues

If you encounter issues with the `curate` command:
- Use the `-v` flag to enable verbose output
- Set smaller batch sizes in your config.yaml
- Ensure the LLM model supports proper JSON output
- Install json5 for enhanced JSON parsing: `pip install json5`

### Parser Errors

- Ensure required dependencies are installed for specific parsers:
  - PDF: `pip install pdfminer.six`
  - HTML: `pip install beautifulsoup4`
  - YouTube: `pip install pytubefix youtube-transcript-api`
  - DOCX: `pip install python-docx`
  - PPTX: `pip install python-pptx`
