Generative AI: Build vs. Buy and Choosing the Right Path at the Crossroads

To Build or Not To Build?

Every application, SaaS, mobile, e-commerce, media property, website, enterprise data-lakes & beyond- will be powered by Large Language Models (LLMs) within the next 5 years. With the rate of change in today’s digital landscape, it may even be sooner. Generative AI capabilities have become essential for businesses to enhance customer interactions and streamline operations.

Many organizations, big and small, often find themselves at a crossroads, seeking to upgrade their potentially outdated technology into a more advanced generative AI system. Others are venturing into this space for the first time, aiming to implement a solution tailored to their specific needs. In either case, the choice between building and buying holds significant implications for the success of their application and often is one of the key decisions for ultimately shaping their ability to not only survive but also thrive in this competitive market. So, if you know you need an AI strategy, the first choice you’ll have to commit to is deciding if you will build or do you buy. As developing a foundational LLM is generally beyond the scope of most companies who will leverage an LLM-as-a-service provider such as OpenAI, for the sake of this argument, we’ll assume that “building” an LLM starts with an open source model, such as those found on HuggingFace.

How to Think Strategically About GenAI

In the landscape of today’s world, it becomes essential for companies to align with the needs and expectations of their customers and users while positioning defensively against the competition. When choosing between the momentous journey of developing an in-house Large Language Model or purchasing the use of one, there are three crucial factors that demand careful consideration: Manpower. Budget. Time.

Assessing your organization’s available resources and expertise is crucial. Do you have the manpower, and do they have the capability to build a generative AI model from scratch? This requires an immense amount of knowledge about the space and particularly high costs and can take several years, which leads to budget. Have you considered all related factors to building an LLM outside of just purchasing the necessary building blocks, and can you spare the time it takes without seeing any potential return on investment for the building duration? Building a generative AI platform from scratch can be time-consuming, requiring thorough research, data collection, and model development.

The timeline available to complete the project is equally important. Almost every potential customer with this use case ‘wants to have something in place yesterday.’ So, can you really afford to wait the months (or even longer) to build?

By carefully considering the manpower, budget constraints, and timeline requirements, you can strategically decide whether to build or buy a generative AI platform. Assessing these factors will help you align your approach with your organization’s capabilities, financial situation, and project timelines, ultimately leading to an informed decision that meets your strategic objectives. Like any other critical decision in business and life, building out a list of pros and cons is tried and true.

Pros of Building a Generative AI Platform

Customization and Control: Building a generative AI platform from scratch allows you to have complete control over its features, functionality, and design. This level of customization enables you to tailor the tool specifically to your organization’s unique needs, ensuring it aligns perfectly with your requirements and workflows.

Integration Flexibility: You can integrate it with your existing systems and databases, allowing for seamless collaboration and data utilization. This integration capability enables you to create a highly integrated and personalized user experience that will ensure a happy user experience.

Cons of Building a Generative AI Platform

Technical Expertise: Building a generative AI platform from scratch requires a team with expertise in natural language processing (NLP), machine learning (ML), dialog management, and Large Language Models (LLM). Integrating these components can be complex and challenging, requiring specialized knowledge and building a team of costly data science and ML engineer resources.

Maintenance and Upgrades: Once it is built, ongoing maintenance, training updates, and troubleshooting become your organization’s responsibility. This requires a dedicated technical team to handle the tool’s continuous development, support, and improvement.

High Costs: This regularly comes with significant costs, including hiring developers with specialized skills, acquiring necessary tools and technologies, ongoing maintenance, and resource allocation. Building a Generative AI Tool can be a substantial investment for an organization.

Diversion from Core Product/Service/Offering: This may divert resources away from an organization’s core competencies, potentially impacting the development and support of your primary products or services. Assessing whether building a tool aligns with your organization’s strategic goals is crucial.

Security and Data Privacy: It also requires implementing robust security measures and ensuring compliance with data protection regulations. Failure to address these aspects adequately could expose your organization to security risks and legal liabilities.

Pros of Buying a Generative AI Platform Service

Rapid Deployment and Out-of-Box Functionality: Purchasing a generative AI platform service enables quick implementation, usually via APIs. These ready-made solutions offer a significant portion of the desired functionality right out of the box, accelerating time-to-market and providing immediate value to your organization.
