The True Cost of Generative AI for the Enterprise
In today's article, we will delve into the true cost of employing generative AI, particularly focusing on Large Language Models (LLMs), and discuss the crucial factors that enterprises need to consider beyond mere subscription fees. While generative AI can be a great asset for consumers and small-Scale usage, employing it within an enterprise setting requires careful evaluation of the various cost factors involved, considering the sensitivity, confidentiality, and proprietary nature of enterprise data.
Introduction
Let's begin with a captivating anecdote - at a recent wedding, the best man was nowhere to be found until he emerged from a back room, typing away on his laptop. With the help of a consumer chatbot, Chat GPT, he managed to craft an impressive speech in no time. For consumer use cases, the affordability of chatbots like Chat GPT, priced under $25/month, makes them an excellent choice. However, when it comes to enterprises dealing with confidential data, it's essential to evaluate the comprehensive costs of generative AI.
1. Use Case Analysis
One size does not fit all when it comes to generative AI in the enterprise. Every use case demands specific methods and computation. It is crucial to work with a partner or vendor that allows for a pilot program to identify pain points, test efficacy, and explore different models. By customizing the solution to meet enterprise requirements, cost efficiencies can be maximized.
2. Understanding Model Size
The size and complexity of a generative AI model significantly impact pricing. Vendors often offer pricing tiers based on model size, which is determined by the number of parameters. Different models excel in various use cases such as language translation or Q&A. Assess potential vendors based on their model access policies and continuous innovation in proprietary models.
3. Pre-training Costs
Pre-training a language model from scratch is resource-intensive, requiring immense compute power, time, and effort. Enterprises rarely undertake this approach due to its cost-prohibitive nature, as seen with GPT-3's pre-training costs exceeding millions. Leveraging pre-trained LLMs offers a more cost-effective alternative.
4. Inferencing Costs
Inferencing is the process of generating a response using a language model. The cost of inference is determined by the number of tokens used in both the prompt and the completion. Effective prompt engineering ensures tailored responses without extensive model alterations, providing cost-effective results.
5. Tuning the Model
Tuning involves adjusting the parameters of the model to improve performance or achieve cost efficiencies. Fine-tuning extensively adapts the model, while parameter efficient fine-tuning focuses on task-specific performance without substantial cost increases. Different tuning methods cater to specific use cases, making it essential to select the most suitable approach.
6. Hosting the Model
Hosting the model becomes Relevant when fine-tuning or deploying a customized version. API inference is suitable when no changes are made to the underlying model. On the other HAND, hosting a model requires additional compute resources and incurs hourly costs. Choosing the appropriate hosting method depends on the enterprise's specific needs.
7. Deployment Options
Enterprises can opt for Software-as-a-Service (SAS) or on-premise deployment. SAS offers predictable costs, eliminates infrastructure concerns, and provides scalability. On-premise deployment, while adhering to certain industry regulations, requires the procurement and maintenance of GPUs. Deciding between the two depends on the industry, regulations, and data security considerations.
Pros and Cons
Pros of employing generative AI in the enterprise include enhanced productivity, improved efficiency, and customized solutions. However, challenges may arise with control over data, security concerns, and the possibility of unforeseen costs. Careful evaluation and choosing the right partner can mitigate these cons effectively.
Conclusion
Understanding the true cost of generative AI is imperative for making informed decisions within an enterprise setting. By carefully analyzing use cases, model size, pre-training costs, inferencing costs, tuning methods, hosting options, deployment preferences, and considering both pros and cons, enterprises can navigate the complexities of generative AI adoption and leverage its benefits successfully.
