Did you enjoy the post on vibe coding last week? It's pretty empowering to know that a non-technical person can now develop applications using AI. It opens the door for lots of opportunities to start a tech company. So, what's on the agenda this week? How about synthetic data? More specifically, the use of synthetic data in training newer generations of Large Language Models (LLMs). Sound interesting? Let's dig into it now.
As we progress farther into the age of artificial intelligence, the fuel powering the engine of LLMs is evolving. We've talked many times before that this fuel is data, but we're not interested in just any data. Increasingly, synthetic data is being used alongside or even in place of natural (real-world) data in the training of future LLMs.
For AI consultants and aspiring entrepreneurs, understanding the differences between synthetic and natural data, and the impact on model performance, safety, and alignment, is more than just academic. It’s absolutely crucial. To help you get up to speed, let's explore the following today:
Natural data refers to information generated by real human activity. It includes text from books, websites, social media, legal documents, academic papers, and conversations. It is noisy, diverse, and often messy—but it reflects authentic human language, intent, and complexity. It reflects reality because it's 100% real.
Synthetic data, on the other hand, is artificially generated by machines, such as LLMs. This often means:
Synthetic data can be created at scale and customized for specific applications. It allows AI developers to sidestep licensing restrictions or privacy issues tied to real-world data.
There are several reasons why synthetic data is now being incorporated into new LLMs:
1. Scale Without Limits
Synthetic data can be generated endlessly. That’s a massive advantage in a world where trillion-parameter models require equally vast training data.
2. Customization
Developers can generate domain-specific data for medical, legal, or technical use cases, helping to create LLMs that are more specialized.
3. Bias Correction
By rebalancing synthetic datasets, developers can mitigate historical or cultural biases present in natural data sources.
4. Privacy and Safety
Synthetic data avoids the inclusion of sensitive or personally identifiable information (PII), making models safer for public and enterprise use.
5. Simulated Edge Cases
Models can be trained on rare or hypothetical situations that might not appear often in natural datasets (e.g., emergency scenarios, rare diseases).
1. Model Collapse and Feedback Loops
Training models on data generated by previous models can lead to a "model collapse" as quality degrades over generations of models. It’s like making a photocopy of a photocopy, where detail and richness are lost in each copy.
2. Loss of Human Nuance
Synthetic text often lacks the subtlety, humor, ambiguity, and error that make human communication feel authentic and natural. Models trained on overly synthetic data may become sterile or disconnected from how people actually talk.
3. Over-Optimization
When models are trained on data that is “too perfect,” they may fail to generalize well in real-world applications, especially when facing unexpected inputs or natural language variation.
4. Reinforced Errors
If synthetic data is generated from flawed models or biased prompts, those issues are amplified in the next generation. It creates a kind of "generational drift" that can harm safety and performance.
5. Opacity and Trust
It becomes harder for users and businesses to trust outputs when they don’t understand what kinds of data the model was trained on. Transparency becomes a challenge.
With synthetic data becoming a core ingredient in many state-of-the-art LLMs, AI consultants must know how to ask the right questions and evaluate models effectively for their clients. Here are some suggestions to help:
1. Understand the Data Lineage
Ask vendors or model providers:
Example: A healthcare startup should prefer a model trained on rigorously curated and verified clinical data, natural or synthetic, rather than generic internet-based data.
2. Balance Generalization vs. Specialization
Synthetic data allows models to specialize quickly, but general models may still be better for open-ended tasks. Guide clients toward:
3. Prioritize Transparency and Auditability
If a vendor can’t clearly explain how their model handles data quality, ethics, and safety in the synthetic data pipeline, treat it as a red flag. Encourage your clients to work with providers committed to auditable AI.
4. Consider Cost vs. Accuracy Tradeoffs
Some synthetic-heavy models may be cheaper due to the reduced data acquisition costs. However, if quality is essential, such as in legal or policy drafting, clients may be better off paying more for models with a larger natural dataset base.
5. Pilot Across Multiple Models
Help clients set up lightweight pilot tests with multiple LLMs to evaluate the following:
Often, the difference between a synthetic-heavy model and a natural-data-heavy model becomes clear through side-by-side comparison.
As a new AI consultant, your job is not just to help clients implement AI. It’s also to help them implement the right AI for their business needs.
Synthetic data is here to stay, and its role in training future LLMs will likely grow. But so will the risks of over-dependence. Helping your clients navigate this shifting landscape involves:
Synthetic data opens the door to powerful new AI capabilities, but also demands a more intentional, cautious approach to LLM selection and deployment. As a consultant or entrepreneur in the AI space, your ability to understand and explain these trade-offs will make you a trusted advisor in an increasingly complex AI field. By focusing on transparency, context-driven evaluation, and risk-aware strategies, you'll help your clients pick the right model for their needs, whether fueled by human language, machine imagination, or (most likely) both.

Synthetic Data vs. Natural Data in Training Future LLMs: What We Need to Know
As we progress farther into the age of artificial intelligence, the fuel powering the engine of LLMs is evolving. We've talked many times before that this fuel is data, but we're not interested in just any data. Increasingly, synthetic data is being used alongside or even in place of natural (real-world) data in the training of future LLMs.
For AI consultants and aspiring entrepreneurs, understanding the differences between synthetic and natural data, and the impact on model performance, safety, and alignment, is more than just academic. It’s absolutely crucial. To help you get up to speed, let's explore the following today:
- The definitions and differences between synthetic and natural data.
- The risks and benefits of training LLMs on synthetic data.
- Implications for model selection in business environments.
- How you, as an AI consultant, can guide your clients in choosing LLMs based on their data lineage.
What's the Difference Between Natural vs. Synthetic Data?
Natural Data
Natural data refers to information generated by real human activity. It includes text from books, websites, social media, legal documents, academic papers, and conversations. It is noisy, diverse, and often messy—but it reflects authentic human language, intent, and complexity. It reflects reality because it's 100% real.
Synthetic Data
Synthetic data, on the other hand, is artificially generated by machines, such as LLMs. This often means:
- Text generated by existing language models.
- Simulated conversations or tasks created through scripted prompts.
- Augmented or manipulated natural data (e.g., paraphrased, translated, or summarized).
Synthetic data can be created at scale and customized for specific applications. It allows AI developers to sidestep licensing restrictions or privacy issues tied to real-world data.
Why Are LLMs Using Synthetic Data?
There are several reasons why synthetic data is now being incorporated into new LLMs:
- Exhaustion of High-Quality Natural Data: Most publicly available high-quality datasets have already been scraped and used. There’s diminishing marginal return in collecting more.
- Legal and Ethical Barriers: Real-world data often comes with copyright issues, data privacy concerns, and ethical challenges.
- Controlled Distribtion: Synthetic data can be crafted to over-represent underrepresented languages, dialects, or content types in an attempt to balance bias present in natural data.
- Cost and Speed: Synthetic data can be generated quickly, allowing for rapid experimentation and iterative training of models.
- Alignment and Safety: Developers can tune synthetic data to reinforce alignment goals to ensure the LLM responds in ways that are safer, more polite, or more informative.
Benefits of Training with Synthetic Data
1. Scale Without Limits
Synthetic data can be generated endlessly. That’s a massive advantage in a world where trillion-parameter models require equally vast training data.
2. Customization
Developers can generate domain-specific data for medical, legal, or technical use cases, helping to create LLMs that are more specialized.
3. Bias Correction
By rebalancing synthetic datasets, developers can mitigate historical or cultural biases present in natural data sources.
4. Privacy and Safety
Synthetic data avoids the inclusion of sensitive or personally identifiable information (PII), making models safer for public and enterprise use.
5. Simulated Edge Cases
Models can be trained on rare or hypothetical situations that might not appear often in natural datasets (e.g., emergency scenarios, rare diseases).
Risks of Relying on Synthetic Data
1. Model Collapse and Feedback Loops

Navigating LLM Selection: Guidance for AI Consultants
With synthetic data becoming a core ingredient in many state-of-the-art LLMs, AI consultants must know how to ask the right questions and evaluate models effectively for their clients. Here are some suggestions to help:
1. Understand the Data Lineage
Ask vendors or model providers:
- What proportion of the training data is synthetic vs. natural?
- Was synthetic data generated by a base model or through human-curated prompts?
Are domain-specific or enterprise-safe filters used?
Example: A healthcare startup should prefer a model trained on rigorously curated and verified clinical data, natural or synthetic, rather than generic internet-based data.
2. Balance Generalization vs. Specialization
Synthetic data allows models to specialize quickly, but general models may still be better for open-ended tasks. Guide clients toward:
- General LLMs (like GPT-4 or Claude) for wide-ranging content generation or summarization.
- Synthetic-trained niche models (e.g., finance, law) for narrowly focused scenarios.
3. Prioritize Transparency and Auditability
If a vendor can’t clearly explain how their model handles data quality, ethics, and safety in the synthetic data pipeline, treat it as a red flag. Encourage your clients to work with providers committed to auditable AI.
4. Consider Cost vs. Accuracy Tradeoffs
Some synthetic-heavy models may be cheaper due to the reduced data acquisition costs. However, if quality is essential, such as in legal or policy drafting, clients may be better off paying more for models with a larger natural dataset base.
5. Pilot Across Multiple Models
Help clients set up lightweight pilot tests with multiple LLMs to evaluate the following:
- Accuracy and relevancy of responses
- Sensitivity to ambiguity or edge cases
- Tone and communication style
- Ability to follow instructions and constraints
Often, the difference between a synthetic-heavy model and a natural-data-heavy model becomes clear through side-by-side comparison.
A Sample LLM Evaluation Matrix for Clients
| Criteria | Synthetic-Heavy Model | Natural-Data-Heavy Model |
|---|---|---|
| Customization | High (easy to fine-tune) | Medium |
| General Language Fluency | Medium to High | High |
