What are Large Language Models (LLMs) and GPTs?

In today’s rapidly evolving digital landscape, two acronyms have been making waves across industries: LLMs and GPTs. But what do these terms really mean, and why are they becoming increasingly important?

What are Large Language Models (LLMs) and GPTs?

As the digital age progresses, two terms frequently emerge across various discussions and applications: LLMs (Large Language Models) and GPTs (Generative Pre-trained Transformers). Both are at the forefront of artificial intelligence, driving innovations and reshaping human interaction with technology.

Large Language Models (LLMs)

LLMs are advanced AI systems trained on extensive datasets, enabling them to understand and generate human-like text. They can perform tasks such as translation, summarisation, and content creation, mimicking human language understanding with often remarkable proficiency.

Generative Pre-trained Transformers (GPT)

GPT, a subset of LLMs developed by OpenAI, demosntrates exactly what can be done with the capabilities of these models in processing and generating language. Through training on a wide range of internet text, GPT models are capable of understanding context, emotion, and information, making them invaluable for various applications, from automated customer service to creative writing aids.

The Intersection of LLMs and GPTs

While GPTs fall under the umbrella of LLMs, their emergence has spotlighted the broader potential of language models. Their synergy lies in their ability to digest and produce text that feels increasingly human, pushing the boundaries of machine understanding and creativity.

The Risks of LLMs and GPTs

Quite apart from the data quality-specific risks of LLMs, which we go into below, there are a number of risks and challenges facing humans as a consequence of Large Language Model development, and in particular the rise of GPTs like ChatGPT.  These include:

  • A low barrier to adoption: The incredible ease with which humans can generate plausible-sounding text has created a paradigm shift. This new age, whereby anyone, from a school-age child to a business professional or even their grandparents, can write human-sounding answers on a wide range of topics, means that the ability to distinguish fact from fiction will become increasingly complex.
  • Unseen bias: Because GPTs are trained on a specific training set of data, any existing societal bias is baked-into the programming of that GPT. This is necessary, for example, when developing a training manual for a specific program or tool. But it’s riddled with risk when attempting to make credit decisions, or provide insight into society, if the biases lie undetected in the training dataset. This was already a problem with machine learning before LLMs came into being; their ascendency has only amplified the risk.
  • Lagging safeguards and guardrails: The rapid path from idea to mass adoption for these technologies, especially with regard to OpenAI’s ChatGPT, has occurred much faster than company policies can adapt to prevent harm, let alone regulators acting to create sound legislation. As of August 2023, ZDNet wrote that ‘75% of businesses are implementing or considering bans on ChatGPT.’ Simply banning the technology doesn’t help either; the massive benefits of such innovation will not be reaped for some considerable time. Striking a balance between risk and reward in this area will be crucial.
The Role of Data Quality in LLMs and GPTs

High-quality data is the backbone of effective LLMs and GPTs. This is where Datactics’ Augmented Data Quality comes into play. By leveraging advanced algorithms, machine learning, and AI, Augmented Data Quality ensures that the data fed into these models is accurate, consistent, and reliable. This is crucial because the quality of the output is directly dependent on the quality of the input data. With Datactics, businesses can automate data quality management, making data more valuable and ensuring the success of LLM and GPT applications.

Risks of Do-It-Yourself LLMs and GPTs in Relation to Data Quality

Building your own LLMs or GPTs presents several challenges, particularly regarding data quality. These challenges include:

  • Inconsistent data: Variations in data quality can lead to unreliable model outputs.
  • Bias and fairness: Poorly managed data can embed biases into the model, leading to unfair or skewed results.
  • Data privacy: Ensuring the privacy of the data used in training these models is crucial, especially with increasing regulatory scrutiny.
  • Complexity in data management: The sheer volume and variety of data needed for training these models can overwhelm traditional data management strategies.

Conclusion

The development and application of LLMs and GPTs are monumental in the field of artificial intelligence, offering capabilities that were once considered futuristic. As these technologies continue to evolve and integrate into various sectors, the importance of underlying data quality cannot be overstated. With Datactics’ Augmented Data Quality, organisations can ensure their data is primed for the demands of LLMs and GPTs, unlocking new levels of efficiency, innovation, and engagement while mitigating the risks associated with data management and quality.

What is a Data Lake, a Data Warehouse, and a Data Lakehouse?

 

Data lakes, data warehouses, and data lakehouses are all data storage solutions that have their own advantages and disadvantages. The choice of which data storage solution to use depends on the needs of the organization and has implications in a wide range of areas including cost, data quality and speed of access

  • A data lake is a repository of data that can be used for data analysis and data management. It is a data storage architecture that allows data to be ingested and stored in its native format, regardless of structure. This flexibility makes it ideal for data that is constantly changing or difficult to categorize. 
  • A data warehouse is a database that is used to store data for reporting and analysis. In contrast to a data lake, a data warehouse is designed for data that is more static and easier to organize. Data warehouses impose and enforce schemas on ingested data, whereas data lakes do not.
  • A data lakehouse is as its name suggests, a hybrid of a data warehouse and a data lake, combining the flexibility of a data lake with the structure of a data warehouse.

What is the implication for data quality?

The choice of which type of data storage to use can have a significant impact on data quality.

Data lakes are typically used for storing large amounts of unstructured data. Unstructured data is more difficult to govern and manage than structured data. As a result, data lakes are more likely to have lower data quality than data warehouses, and can lead to duplicate or inconsistent data. In contrast, data warehouses are more likely to impose strict rules that can exclude important data. 

The ability to manage and improve data quality is doubtless improved when data is governed by a schema, as is the case with data warehouses. When data is stored in its native format, as is the case with data lakes, the quality of the data can be more difficult to control. 

The choice of data storage architecture should be made based on the needs of the business and the nature of the data being stored.

Emerging concepts such as data mesh and data fabric attempt to exploit the benefits of data lakes, data warehouses and data lakehouses through a combination of approaches such as local governance, self-service solutions, and interoperable data standards. For more on this subject read this article on data fabric and data mesh.

What about the difference in cost?

The choice of data storage solution also affects the cost of storing and accessing data. Data warehouses are typically more expensive than data lakes because they require more hardware and software resources. Data lakehouses are usually more expensive than data lakes or data warehouses because they combine the features of both.

How about speed?

The choice of data storage solution also affects the speed at which data can be accessed. Data lakes can be faster than data warehouses because they can be queried in parallel. Data warehouses can be faster than data lakes if the right indexes are used. Data lakehouses can be faster than both if they are designed properly.

What is the impact on data pipelines, and data governance?

The impact of differing methods of data storage on how data is governed, managed and curated for healthy pipelines into businesses varies depending on the needs of the organization.

  • Organizations that need to store large amounts of unstructured data may find that a data lake is the best solution for their needs.
  • Organizations that need to store large amounts of structured data may find that a data warehouse is the best solution for their needs.
  • Organizations that need to store large amounts of both structured and unstructured data may find that a data lakehouse is the best solution for their needs.

The decision of which method to use should be based on the specific needs of the organization rather than on generalities about each method.

What is Data Lineage?

Data lineage is the process of mapping where your data has originated from and where it ends up. It enables enterprises to track the flow of data and quickly identify where errors have occurred during the data lifecycle.

what is data lineage

Data lineage is a critical component of any enterprise data management. It tracks where the data has originated from and follows its journey through the enterprise, enabling data stewards to see who has interacted with the data and at what point. As a result, data quality can be improved as it becomes easier to trace errors back to their original source through an audit trail, thus increasing accountability and transparency. Being able to identify where changes have been made and by whom helps organisations mitigate risks and prevent serious data breaches, particularly for financial services firms and others who are subject to strict regulatory compliance.
