Despite AI’s growing momentum, many senior leaders still await clear ROI. A recent industry survey reveals that 30% of Chief Data and Analytics Officers (CDAOs) struggle to measure the impact of data, analytics, and AI on business outcomes, highlighting a significant gap between investment and tangible results.

According to research, over 80% of AI projects fail, with poor data quality being a significant contributing factor to these failures. These aren’t just operational inefficiencies; they’re missed opportunities, flawed forecasts, and reputational risks. As AI integrates deeper into business processes, the limitations of model-centric approaches become more evident.

That’s why leading organizations are now shifting their attention from model performance to data reliability, governance, and lifecycle management. This is the foundation of data-centric MLOps and LLMOps, a modern operational framework built to scale AI systems without compromising data trust, accuracy, or compliance.

With 60% of AI training data expected to be synthetic by 2024 and a shift toward smaller, task-specific AI models by 2027, the ability to manage data at scale with precision and accountability is now a competitive differentiator.

This blog breaks down the shift towards data-centric MLOps and LLMOps, showing how these evolving practices help build scalable, secure, and high-performing AI systems that deliver measurable business value.

Data-Centric MLOps & LLMOps

MLOps (Machine Learning Operations) refers to the practice of managing the lifecycle of machine learning models. It covers everything from model development and deployment to monitoring and maintenance. The goal is to create a smooth and scalable process for taking models from development to production while ensuring that they perform as expected.

What is Data-Centric MLOps?

In a data-centric approach, the primary focus shifts from refining models and algorithms to optimizing the data itself. This means that data is continually assessed and improved to ensure it is clean, relevant, and well-labelled. 

Rather than spending excessive time fine-tuning the model, data-centric MLOps emphasizes the importance of iterating on the data pipeline and ensuring that the data feeding into the models is accurate, well-organized, and up-to-date. 

What is Data-Centric LLMOps? 

LLMOps (Large Language Model Operations) is a specialized subset of MLOps that focuses on managing and operationalizing large language models, such as GPT, BERT, or other NLP models. These models require massive datasets to function effectively and present unique challenges, such as ensuring data diversity, fairness, and real-time performance monitoring.

In LLMOps, the data-centric approach plays an equally important role as it does in MLOps. Given that LLMs require vast amounts of diverse, high-quality data, ensuring that this data is appropriately managed, labelled, and curated is essential. Data-centric LLMOps involves implementing strategies to optimize the datasets used for training these models and maintaining data consistency during deployment.

Benefits of a Data-Centric Approach

Data-centric ML focuses on improving the quality of the data rather than constantly tweaking the model. The emphasis is on refining and iterating on the data to ensure it is clean, consistent, and well-labelled.

One of the primary benefits of a data-centric approach is its ability to significantly improve model accuracy. For example, experiments on MNIST, Fashion MNIST, and CIFAR-10 showed that data-centric methods, such as deduplication, label correction, and augmentation, outperformed model-centric hyperparameter tuning by 3%+ in accuracy, using the same ResNet-18 architecture. This highlights the value of focusing on high-quality data, rather than relying solely on model optimization.

The advantages of a data-centric approach are numerous:

• Improved accuracy: By treating data as a strategic asset, organizations can make more informed decisions and more accurate predictions.
• Reduced errors and inconsistencies: Data-centric practices ensure consistency across datasets, reducing errors and increasing trust in AI models.
• Better insights: High-quality data improves the reliability of the insights AI models generate, which is crucial for decision-making.
• Cost efficiency: By minimizing the need for large-scale data transformations and correcting errors in the data upfront, organizations can save on operational costs.
• Improved data accessibility: A standardized data management system enables stakeholders across the business to access relevant data as needed.

Data-Centric vs. Data-Driven

Many people often confuse a data-centric approach with a data-driven approach. While both are related to the use of data in machine learning, the key distinction lies in their purpose and focus.

1. Data-Driven Approach

A data-driven approach revolves around the collection, analysis, and extraction of insights from data. This method, often associated with “analytics,” focuses on using large amounts of data to inform decisions, models, and strategies. The primary goal is to leverage data to gain insights that guide business actions.

2. Data-Centric Approach

In contrast, a data-centric approach emphasizes using data to define and shape what should be created. It prioritizes ensuring that the data feeding into AI models is clean, reliable, and consistent. Here, data is treated as a permanent asset that drives the evolution of both the models and the applications, rather than just a tool for decision-making.

Let’s now understand how a data-centric approach differs from a model-centric approach.

Data-Centric vs. Model-Centric MLOps Approaches

As machine learning practices evolve, the debate between data-centric and model-centric MLOps approaches intensifies. Below is a table highlighting the key differences between the two approaches.

Hybrid Approach

While the differences between model-centric and data-centric approaches are clear, most production-grade AI systems today don’t rely on one or the other in isolation. A hybrid approach, where high-quality data pipelines feed into optimized models, is what enables scalability and resilience. In practice, this means refining both the model architecture and the data that powers it, based on real-world usage and feedback.

Tesla and OpenAI are prime examples of this phenomenon. Tesla’s Data Engine actively captures edge cases from its vehicle fleet, labels them, and retrains models to handle rare driving scenarios, combining large-scale data curation with task-optimized models like HydraNet. 

Similarly, OpenAI trains GPT-4 on trillions of tokens using techniques like RLHF, but its Custom Models Program shows a shift toward pairing proprietary datasets with domain-specific fine-tuning pipelines. 

Challenges with Model-Centric ML and the Shift to Data-Centric MLOps

Traditional model-centric ML focuses heavily on optimizing model architecture and fine-tuning hyperparameters. While this approach works well in certain industries, it falls short in industries with vast amounts of standardized data, as well as in those with specialized requirements or small, inconsistent datasets. Here's why.

1. Customized Needs Across Industries

For many industries, such as manufacturing, healthcare, and engineering, model-centric machine learning (ML) falls short because it cannot easily adapt to diverse use cases. 

For example, in manufacturing, a company that produces various products may require multiple machine learning models to detect production errors across different product lines.  The inability to customize models for specific products or industry needs is a major limitation of the model-centric approach.

2. Limited Data Availability

In many industries, particularly those outside of technology, there are often small datasets that do not align with the assumptions of model-centric approaches. 

For instance, a wind turbine company looking to develop a predictive maintenance solution faces a small sample size of images showing wear and tear on turbines. Although there may be thousands of images of healthy turbines, there could be only around 100 images of turbines that show wear, which represents a minuscule percentage of the total dataset.

In such cases, the model-centric approach, which focuses primarily on optimizing model architecture, does not address the real issue: the lack of sufficient data for model training. Without focusing on improving the dataset through methods like data augmentation or label correction, the results will likely be unsatisfactory.

3. Gaps Between Proof of Concept and Production Systems

Model-centric ML often fails when transitioning from proof of concept (POC) to production, especially in diverse environments. A Gartner report highlighted that 30% of generative AI projects are expected to be abandoned after the proof of concept (POC) by the end of 2025 due to poor data quality, escalating costs, and unclear business value. This is particularly true in sectors like healthcare, where hospitals using different machines for patient scans face significant data inconsistencies. 

Such challenges reveal that model-centric approaches are often inadequate when real-world data complexity and operational scalability are at stake, requiring more reliable, data-centric solutions.

With an understanding of data-centric and model-centric approaches in MLOps and LLMOps, it is essential to explore the practical components that comprise a data-centric strategy. Let’s break down the key components of a successful data-centric MLOps strategy.

Key Components of Data-Centric MLOps

[Create a listicle]

A data-centric MLOps approach involves optimizing data quality, ensuring consistency, and continuously refining the data throughout the machine learning lifecycle. Below are the essential components that define a data-centric MLOps strategy:

1. Label Quality and Error Analysis

The foundation of a data-centric MLOps approach is data labelling, which assigns meaningful labels to data, thereby providing the necessary context for machine learning models to learn. 

Errors in labelling, especially in edge cases, can lead to misleading patterns and degrade model reliability. Rather than labelling at scale from the outset, it’s more effective to refine label guidelines through iterative error analysis. This process helps isolate misclassified samples, align labelling across teams, and reduce ambiguity. Clean labels offer more signal than larger, noisier datasets.

2. Data Augmentation with Constraints

Data augmentation involves generating new data points by manipulating existing data, such as rotating or zooming images in computer vision tasks, or generating synthetic data points in natural language processing (NLP). This technique helps overcome the challenges posed by small datasets by creating additional training examples.

Poorly constrained augmentation can introduce artifacts or amplify noise, harming generalization. The focus should remain on augmenting only high-confidence data while pruning noisy or misleading samples. 

3. Feature Engineering 

Feature engineering is the process of changing raw data into a more usable form by adding relevant features or modifying existing ones. Well-engineered features often outperform complex model architectures. This involves synthesizing new features, selecting signal-rich inputs, and correcting for bias in source data. 

Feature engineering involves understanding both the data and the model. Adding new features that are not present in the raw data requires a deep understanding of the data domain and how different features interact with the model’s behaviour.

4. Data Versioning and Pipeline Governance

Data versioning is crucial for reproducibility, particularly when datasets evolve across multiple experiments. Without it, debugging ML pipelines or understanding model drift becomes a matter of guesswork. Tools like DVC and Lakehouse architectures enable lineage tracking, version control, and scalable access across environments. 

5. Domain Expertise 

Data-centric MLOps relies heavily on embedding subject matter expertise throughout the pipeline.  While ML engineers and data scientists are experts in algorithms and model optimization, subject matter experts (SMEs) provide critical insights into the data itself. These experts can identify subtle discrepancies or nuances that data scientists might overlook, such as the importance of specific features or the context of particular data points.

Domain knowledge is particularly valuable when the data is complex or highly specialized, such as in healthcare or finance, where industry-specific understanding is necessary for accurate model development.

The components outlined for MLOps also apply to LLMOps, but there are additional challenges and nuances when it comes to large language models. Let’s explore how to implement a data-centric approach specifically for LLMs, ensuring scalability and fairness in real-time applications.

Implementing Data-Centric LLMOps

Building reliable, fair, and scalable LLM systems isn’t just about choosing the biggest model; it’s about managing the right data, in the right way. A data-centric approach to LLMOps focuses on data quality, consistency, and usability throughout the lifecycle of large language models. Let’s break down how this works in practice.

1. Challenges with Large-Scale Data in LLMOps

LLMOps must handle massive, heterogeneous datasets sourced from multiple domains, languages, and formats. This diversity is essential to train models that generalize well and avoid overfitting to narrow contexts. However, managing such large-scale data introduces unique challenges:

• Data preparation and annotation require automated, scalable pipelines to handle continuous inflows and updates, reducing manual bottlenecks.
• Maintaining data provenance and lineage supports compliance with emerging regulations and ethical AI standards.

2. Ensuring Fairness and Reducing Bias

Fairness in LLM outputs hinges on the representativeness and balance of training data. Data-centric LLMOps frameworks incorporate continuous bias detection and mitigation by:

• Curating diverse datasets that reflect multiple demographics and viewpoints.
• Implementing real-time monitoring of model predictions to detect drift or emerging biases.
• Enforcing governance policies that track data lineage and model decisions for transparency and accountability.
  
  

3.  Retrieval-Augmented Generation (RAG) 

RAG combines static, large-scale datasets with dynamic retrieval of real-time information to improve LLM accuracy and relevance. Data-centric LLMOps pipelines integrate RAG by:

• Connecting LLMs to external knowledge bases or APIs.
• Managing and indexing large corpora for efficient retrieval.
• Monitoring latency and throughput to optimize user experience.

This approach enables models to remain current without requiring expensive full retraining, thereby balancing freshness with scalability.

4. Fine-Tuning vs. Pre-Training

While pre-trained foundation models provide a powerful starting point, fine-tuning on domain-specific, high-quality datasets is essential for task specialization and improved performance. Data-centric LLMOps practices emphasize:

• Continuous data curation to feed fine-tuning cycles with relevant, clean data.
• Automated pipelines for preprocessing steps like tokenization, normalization, and augmentation.
• Version control of datasets and models to enable reproducibility and rollback.

This data-first mindset reduces computational costs and accelerates iteration, ensuring models adapt quickly to evolving business needs. 

‍

Implementing a data-centric LLMOps strategy is crucial, but it doesn’t stop there. To ensure your AI systems are not only scalable but also reliable, it is essential to ensure data quality in both MLOps and LLMOps. Let’s explore how data directly impacts the performance and reliability of AI models.

The Importance of Data in MLOps & LLMOps

For AI models to perform effectively and reliably, the quality and integrity of the data they rely on are critical. A data-centric approach has a direct impact on model performance and operational efficiency. 

Below are key aspects that highlight the significance of quality data in MLOps and LLMOps:

1. Data Quality Over Quantity

Gartner estimates that poor data quality costs organizations an average of $12.9 million per year. This highlights the critical importance of focusing on data quality rather than merely increasing data volume. High-quality data ensures better model accuracy, reduces biases, and ensures AI systems deliver reliable results.

Emphasizing data quality over quantity can prevent costly errors. For example, Unity Software reported a loss of $110 million in revenue and a decline of $5 billion in market capitalization due to poor data ingestion from a large customer. Rather than continuously gathering more data, investing in quality tools to clean, augment, and improve the data used in models can significantly improve their effectiveness and performance.

2. Data Integrity Verification

62% of organizations identify a lack of data governance as a significant barrier to their AI initiatives. Ensuring data integrity through effective governance practices can help prevent data errors and ensure models perform as expected. Verification of data sources and regular checks for consistency are key to building reliable AI systems.

Without proper data governance, organizations face significant risks that can be costly and detrimental to their operations. For example, Citibank faced penalties totalling $536 million in 2020 and 2024 due to failures in data governance. Ensuring data is clean and properly managed can avoid such costly errors.

3. Data Versioning and Governance

Poor data governance can lead to inefficiencies and inaccuracies. 64% of companies report data quality as their biggest challenge in maintaining data integrity. In response, businesses need to invest in data versioning and governance systems to track changes in data, ensuring consistency across the lifecycle of machine learning models.

By using tools like Lakefs or DVC, companies can ensure that they maintain a traceable, consistent record of data throughout the model’s lifecycle, which is critical for debugging, retraining models, and maintaining regulatory compliance. 

4. Data-Model Linkage

Gartner predicts that by 2025, over 55% of all data analysis by deep neural networks will occur at the point of capture in edge systems. This shift highlights the importance of maintaining a strong data-model linkage, allowing models to operate on real-time data and respond more effectively to changing conditions.

BCG notes that leading companies, by utilizing their data and AI capabilities more effectively, have four times more use cases scaled across their businesses. This is driven by their ability to integrate data and models seamlessly, ensuring that models are always aligned with the most up-to-date and relevant data.

Now that we've established the critical role of data quality in MLOps and LLMOps, let’s dive into the best practices that ensure your AI systems remain reliable, scalable, and efficient.
