Overview

MOSTLY AI provides a synthetic data generation platform that enables organizations to create artificial datasets from real-world, sensitive information. The platform is engineered to generate synthetic data that maintains the statistical properties, patterns, and relationships of the original data, crucial for downstream analytical tasks and machine learning model training, while replacing individual records with entirely new, non-identifiable data points. This approach addresses privacy concerns associated with using or sharing production data, particularly in regulated industries.

The core application of MOSTLY AI's technology is to facilitate data-driven development and innovation in environments where access to authentic customer data is restricted due to privacy regulations such as GDPR or internal compliance policies. By producing synthetic versions, developers and data scientists can access realistic, high-fidelity datasets for training machine learning models, testing software applications, developing new features, and conducting analytics without compromising individual privacy. This can accelerate development cycles and reduce bottlenecks traditionally caused by data access limitations.

The platform is designed for technical users, including data scientists, machine learning engineers, and developers, who require programmatic control over data generation and integration into existing data pipelines. It offers a Python SDK and a REST API, allowing for automation and customization of synthetic data creation workflows. Use cases extend across various sectors, from financial services and healthcare, where data privacy is paramount, to retail and telecommunications, where large volumes of customer data are processed. According to a McKinsey report, synthetic data is gaining traction as a method to unlock insights from sensitive data while mitigating privacy risks.

One of the primary benefits of synthetic data is its utility in testing and quality assurance. Development teams can use synthetic data to create comprehensive test suites that cover various edge cases and scenarios, ensuring software robustness before deployment. This is particularly valuable in scenarios involving personal identifiable information (PII) or protected health information (PHI), where using real data for testing is often prohibited. Furthermore, MOSTLY AI's solution supports secure data sharing within an organization or with external partners, enabling collaboration without direct exposure of sensitive information, thereby enhancing data governance and reducing the risk of data breaches.

Key features

Getting started

To begin using MOSTLY AI for synthetic data generation, you can utilize their Python SDK. The following example demonstrates how to connect to the platform, load a dataset, and generate synthetic data.


import pandas as pd
from mostlyai import MostlyAI

# Replace with your API key and instance URL
mostly_ai = MostlyAI(api_key="YOUR_API_KEY", instance_url="YOUR_INSTANCE_URL")

# Load your original dataset (example using a DataFrame)
data = {
    'customer_id': [1, 2, 3, 4, 5],
    'age': [30, 24, 45, 33, 28],
    'salary': [50000, 45000, 70000, 55000, 48000],
    'city': ['New York', 'London', 'Paris', 'New York', 'Berlin']
}
df_original = pd.DataFrame(data)

# Upload the original dataset to MOSTLY AI
dataset = mostly_ai.datasets.upload_dataframe(df_original, name="MyOriginalDataset")
print(f"Original dataset uploaded: {dataset.name} (ID: {dataset.id})")

# Start a synthetic data generation job
synthesis_job = dataset.synthesize()
print(f"Synthesis job started: {synthesis_job.id}")

# Wait for the job to complete (optional, you can also check status asynchronously)
synthesis_job.wait_for_completion()

# Download the synthetic dataset
df_synthetic = synthesis_job.download_dataframe()
print("Synthetic data generated successfully:")
print(df_synthetic.head())

# You can now use df_synthetic for your development, testing, or analytics tasks

This Python code snippet illustrates the basic workflow: authenticating with the platform, uploading source data, initiating a synthesis job, and downloading the resulting synthetic dataset. For more comprehensive examples and detailed API documentation, refer to the MOSTLY AI Python SDK Guide.
