Estimating Costs for Large Language Models in Applications
Introduction:
Estimating the costs associated with building and deploying web applications powered by large language models is a common challenge for developers and businesses venturing into the integration of advanced AI models. In this landscape, having a clear understanding of the financial implications becomes pivotal for strategic budgeting and decision-making. This blog post serves as a practical guide and framework, simplifying the intricate process of cost estimation into manageable steps.
The Challenge:
Developers and businesses are often faced with the daunting task of estimating costs when incorporating large language models like OpenAI’s GPT-4 into their applications. The complexity of this task arises from the need to balance innovation with financial prudence. Without a comprehensive understanding of the financial implications, strategic budgeting and decision-making become increasingly challenging.
The Solution:
First things first, we need to understand the pricing model. OpenAI charges based on the number of tokens processed by their models. For GPT-4, it’s three cents for inputting a thousand tokens and six cents for the output of the same. Now, let’s make some assumptions to get a ballpark figure for our application.
I’m assuming a typical input of 200 tokens and an output of 800 tokens. Why? Because in real-world scenarios, questions or prompts to these models are usually short, but the responses are huge! Now, imagine this: our application is in the hands of a hundred analysts, each throwing in around 30 prompts per day. That’s 252 working days in a year.
Now, let’s do some math. For GPT-4, the annual cost per analyst is around $407, totaling approximately $40,700 for a hundred analysts. If we go for the beefier 32,000 token model, the annual cost per analyst bumps up to about $816, totaling around $81,648 for a hundred analysts.
But how did we get to these numbers? Well, I’ll show you the breakdown. We calculated costs based on 200 input tokens and 800 output tokens per analyst per day. It’s all about breaking down the costs into input and output token components, giving you a clear picture of where your money is going.
This framework is super handy for developers and businesses planning to incorporate large language models into their applications. Remember, these are just assumptions, and you should tweak them based on your specific use case.

Practical Insights:
The post delves into the nuances of token pricing and the assumptions made during the estimation process. By using GPT-4 as an example, the author demonstrates how considerations like input and output token counts, prompts per day, and working days per year contribute to the overall cost calculation. The breakdown of costs per analyst and the annual costs for a hundred analysts provides practical insights for those looking to implement large language models in their applications.
Conclusion and Call to Action:
In conclusion, estimating costs for web applications utilizing large language models is a multifaceted challenge that demands careful consideration. This blog post has aimed to equip readers with a practical framework for navigating this challenge effectively.
