AI: we have a problem no model can fix. If, as today’s powerful models seem to suggest, the next generation of AI can learn from data, then from where will the data come? Right now, real-world data is a resource that’s costly to gather, expensive to annotate, and sometimes, perhaps, too sensitive to share.
Synthetic data is another option. It involves creating a version of data by producing artificial instances, replicating patterns and scenarios for model training and testing. By 2028 it may be integral to a company’s core business model. And its emergence will be about more than volume
In this article, we explore how synthetic data can solve problems of data scarcity, ease privacy constraints, cut development costs, and enhance model training, and what organizations need to do right in order to make it a lasting advantage.
The Data Scarcity Dilemma
AI development is approaching a difficult constraint. For models to be more powerful, they require increasingly larger and diverse dataset to learn from. However, high-quality human-generated text and images, available online for free, is not unlimited. The simplest is already available while things like rare events, unlikely scenarios, and niche expertise are more difficult to acquire, presenting a data wall that can constrict the ability of the AI to adapt to real-world scenarios.
Synthetic data generation is the solution. Rather than using available material, developers could generate fresh examples centered on particular holes in their training sets. This method could be used to, say, produce 502,536 unique, distinct financial news headlines across 13 different categories for NVIDIA’s iterative pipeline. It could provide a solution to a major shortcoming of financial AI training sets: day-to-day events outweighing rarer events like changes in credit ratings and product approvals.
The benefit is both control and scale. Teams can create focused samples when real-world data is hard to find, costly, or in short supply. However, synthetic data is not unlimited in the amount of useful information it can provide. Its value depends on whether generated examples reflect meaningful patterns rather than repeat existing errors.

Privacy First and the Challenge of Responsible AI
AI teams have a tough choice. The use of actual data from the users is not only helpful for increasing relevance but may also involve personal information, which poses several issues related to privacy both in its use, collection, or sharing with the organization for training purposes. The GDPR, EU AI Act, and CCPA make things more complicated.
Masking and anonymization are some of the methods that help protect from personal data. But, when records are stripped of identifiers, you may also lose some of the patterns that make the data set valuable. And if you choose the wrong method, you may still leave some privacy gaps. Synthetic data provides yet another solution: generating ‘fake’ data points with valuable patterns. Its privacy benefits still depend on how the data is created and tested.
Google Research’s Simula framework treats synthetic data generation as a dataset-design problem. It allows developers to control coverage, complexity, and quality, with potential applications in privacy-sensitive and data-scarce fields. For businesses, the opportunity lies in building more flexible training datasets while treating privacy validation and regulatory review as necessary safeguards, not assumptions.
The Economics of AI and the Cost of Better Data
Creating an AI system requires more than model training. Businesses need to gather the right data, format and label it, remove errors, control its storage, and make it ready for multiple rounds of trial and error. These activities can easily cost a lot when done by hand. And it’s not just the cost. It can take weeks for teams to make the data ready.
It might also decrease the time span of this loop. Instead of waiting for the data to occur in the real world, developers would be able to produce labeled samples to train their model for particular tasks. Edge cases, such as hazardous industrial situations, would take too long and even be dangerous or expensive to collect. Thus, having quicker access to these samples would allow for the quicker development and validation of models.
In an AWS industrial-safety computer-vision proof of concept, the cost of collected and annotated images was $3 to $5 an image, versus roughly $0.33 an image for its synthetic-data pipeline, which accounted for specific GPU-inference expenses and the automated-labelling API. This was specific to that solution, but it illustrates why companies need to consider synthetic data as a cost-savings lever, in context with data quality and model results.
Boosting Model Training and Accuracy
Only data-driven Existing training data is the only source an AI model can learn from. If the data is heavily skewed to cover predominantly common cases with few variations, the model might get a shock in instances it is unfamiliar with. And if much of the training data has bias, the model will incorporate these biases into automated decisions.
Synthetically generated data is a way for developers to influence what a model will learn. Developers can enhance coverage for atypical categories, manipulate different types of inputs, and explore the model’s responses to unusual inputs. Synthetic data for machine learning is especially effective when real-world datasets aren’t diverse enough for the model to generalize well to all test cases. But generating artificial data isn’t enough to eliminate bias, especially if the data is generated based on flawed assumptions, the artificial data could create or reinforce bias rather than eliminate it.
Microsoft Research explored an iterative approach in which synthetic training examples were generated according to the current state of the model being trained. The method improved performance over static data generation under a fixed sample or teacher-compute budget. Researchers evaluated it across four mathematical and logical reasoning datasets and four small language models. This finding indicates that the method of producing the synthetic data may matter as much as the volume produced by teams. Companies can benefit from targeted generation and testing to create more robust models.
The Road to 2028 and Synthetic Data as a Strategic Asset
As of 2028, synthetic data in AI development has the potential to be a differentiator for organizations with in-house data-generation pipelines. Organizations that use solely historical data sets have the potential to perpetuate previous gaps and bias.
However, generating more data will not automatically produce better AI. This structure of measuring synthetic data used to develop tool-calling agents is an important step forward.
Validity, fidelity and diversity can help organizations create products and adapt them to market demands. Companies that explore scalable generation capabilities and enforce them with quality controls will be more resilient and succeed.
Conclusion
Data is the driver of AI but the real world won’t provide all the fuel for the future. Synthetic data offer a reliable, ongoing source of new training data provided that organizations oversee the creation of the data and control for quality.
For CIOs, CTOs, and others in business, the answer is to identify the areas where data deficiencies are hindering model innovation, benchmark the synthetic data against reality, and implement governance before scaling up.
Waiting until teams have serious data problems might be the worst thing they could do. Begin working on synthetic data today. The last thing you want is to leave your team behind by rushing in, between data impasses.
