Choose a private large language model (LLM) to ensure data security and governance, tailor user experience, and refine input and output precision — all within your company's domain. You'll have the exclusive control you need, from crafting prompts to integrating the LLM into your custom apps. Keep your data proprietary and your model's insights internal to your enterprise. In this blog, I’ll dive into what you need to know about private LLMs and how to get started.

Open-source initiatives and the rise of serverless architectures have transformed private LLMs into practical tools for businesses. These advancements not only offer a robust framework for data privacy and security but also adapt seamlessly to the specific challenges and unique needs of any organization, lowering barriers to entry and making AI more accessible than ever.

In this blog, we explore:

What are Private LLMs and How Do They Differ from Public LLMs?

Large Language Models (LLMs) — such as GPT-3.5 or GPT-4 used by ChatGPT — have transformed how we think about and interact with AI, offering conversational and content creation capabilities. These models can be categorized into two main types: private and public LLMs, each serving different needs and offering distinct advantages.

With private LLMs, you get an exclusive version of a model for use within your organization’s environment. This gives you control over the LLM and how it behaves. Additionally, every input to and output from the LLM remains securely within your organization’s boundaries, ensuring that sensitive information never leaves your corporate environment.

In contrast, public LLMs — such as a GPT hosted by OpenAI — are hosted by a third party outside of an organization’s environment and available to anyone. The upside is that you do not have to manage or maintain the LLM environment, but this openness requires you to send all queries — including potentially sensitive corporate data and intellectual property — to be processed outside your organization’s environment. This approach raises significant concerns about privacy and the ownership of the data exchanged with the public LLM.

Key considerations for adopting an LLM solution

When adopting an LLM solution, security, control, and cost are the primary considerations. These three things determine whether you choose a Commercial Off-the-Shelf (COTS) application or a custom application and whether you use a public or private LLM.

Understanding the interaction with LLMs: From standard public access to tailored private applications, prioritizing security and customization.

For COTS products, like ChatGPT or Microsoft Copilot, the main advantage is their immediate availability and swift deployment capabilities. With these, your investment is primarily in licensing fees. However, you have limited control over the application’s behavior and features.

Custom applications, in contrast, are designed specifically for your organization, offering full customization. Here, your investment is in development and maintenance, which may take more time initially but provides you with greater control over the application’s behavior.

When it comes to choosing between a public LLM and a private LLM, the decision often rests on your organization’s requirements for data privacy and the desired level of control over the model. While costs may be similar, the trade-offs between the two options are significant.

To illustrate these points, let’s consider how GPT, a popular LLM, is commonly interacted with:

  • Through ChatGPT (COTS app + public LLM): Accessible to anyone, this setup is straightforward but offers little-to-no customization and has data privacy concerns.
  • Through Microsoft Copilot (COTS app + private LLM): Corporate users can interact with some versions of Microsoft Copilot with confidence that data will remain within their corporate ecosystem. However, there are little-to-no customization possibilities.
  • Through custom applications that use GPT hosted by OpenAI (Custom app + public LLM): This approach provides maximum app customization but little control over the LLM’s behavior. Data privacy is also a concern.
  • Through custom applications that integrate GPT via a private instance hosted by Microsoft Azure (Custom app + private LLM): This setup combines the benefits of a custom application with the privacy, security, and control of a private LLM.

Whether opting for the ease and speed of COTS applications or the tailored approach of custom apps, and whether choosing the widespread accessibility of public LLMs or the secure exclusivity of private LLMs, it’s a strategic decision that will shape your organization’s interaction with AI technologies.

Benefits of private LLMs include:

  • Enhanced Data Privacy and Security: Private LLMs provide robust data protection, hosting models within your organization’s secure infrastructure. Data never leaves your environment. This is vital for sectors like healthcare and finance, where sensitive information demands stringent protection and access controls. In contrast, sensitive data must leave your corporate environment to operate with a public LLM, posing severe security concerns.
  • Compliance with Regulations: In many industries and geographies, strict regulations govern the storage, movement, and processing of data. By using a private LLM, you ensure that your data never leaves your environment and is processed in the correct locale to comply with these regulations. For industries subject to laws like GDPR or HIPAA, using a public LLM poses the risk of legal repercussions, fines, and reputational damage from non-compliance.
  • Customization and Competitive Advantage: Unlike one-size-fits-all public models, private LLMs can be fine-tuned to meet specific business needs, understanding and generating text that aligns with unique industry jargon and processes. This bespoke approach not only ensures more accurate and efficient AI applications but also carves out a competitive edge by offering innovative services that are not feasible with generic AI tools. Failing to leverage such customization can result in inefficiencies and place your organization at a disadvantage as competitors harness tailored AI solutions to enhance operations and customer experiences.
