Cost of an AI Prompt

We're Here to Help

As generative AI becomes more integrated into our daily lives, it’s easy to overlook the hidden costs behind every AI-generated response. While we often focus on the benefits of these tools, it’s important to consider the energy consumption and financial costs that come with each AI prompt. In this article, we’ll explore the costs of a single prompt on popular AI platforms and what this means for both users and the environment.

Key Takeaways

  • On average, $1 in electricity spending can buy you an estimated 2,075 ChatGPT prompts in the US.
  • On average, $1 in electricity spending can buy you an estimated 1,203 DALL-E or MidJourney prompts in the US.
  • On average, Grammarly prompts are the least energy-intensive; $1 in electricity spending can buy you an estimated 4,011 prompts in the US.
  • Average AI usage can cost Americans an estimated $14.44 annually in electricity, while heavy AI usage can cost an estimated $28.88.
  • $1 of electricity would go the furthest in Louisiana, allowing for 2,999 ChatGPT prompts.
  • ChatGPT prompts are the most expensive to run in Hawaii, with $1 of electricity only allowing for 808 prompts.

How Much Energy Does a Single AI Prompt Use?

To better understand the costs of generative AI, we first estimated the energy consumed by a single prompt on popular AI tools. The results show that energy use varies across platforms:

  • 0.0015 kWh = 1 Grammarly prompt
  • 0.0029 kWh = 1 ChatGPT prompt
  • 0.0029 kWh = 1 Claude prompt
  • 0.003 kWh = 1 CoPilot prompt
  • 0.0035 kWh = 1 Gemini prompt
  • 0.005 kWh = 1 DALL-E prompt
  • 0.005 kWh = 1 MidJourney prompt

We next estimated how many prompts one dollar of electricity could buy across these platforms.

The amount of electricity $1 can buy varies depending on the AI tool. For instance, you can generate an estimated 2,075 ChatGPT prompts with $1 of electricity in the US. Visual tools like DALL-E and MidJourney are more energy-intensive, allowing around 1,203 prompts for the same cost.

Grammarly is the most efficient, with $1 of electricity powering approximately 4,011 prompts. This variation highlights how certain AI tools, especially those focused on visuals, consume more energy compared to text-based platforms.

When we look at yearly electricity costs based on AI usage, we can see how these figures add up. For minimal use—defined as 1 prompt per day for each AI tool—the cost is relatively low. However, as usage increases, so do the associated energy costs:

Average Annual Electricity Cost of AI Usage by Level of Use
Minimal
(1 prompt/day)
Light
(5 prompts/day)
Average
(10 prompts/day)
Heavy
(20 prompts/day)
$1.44 $7.22 $14.44 $28.88

This breakdown shows that while AI tools are convenient, their energy consumption can quickly become a consideration for more regular users.

How State Electricity Costs Impact AI Usage

Electricity costs vary significantly across the United States, which means the cost of running AI tools like ChatGPT can differ depending on where you live. We explored how much $1 of electricity can buy in terms of ChatGPT prompts in each state, revealing the stark contrast in energy efficiency between high- and low-cost states.

Made with Flourish

Louisiana stands out as the most cost-efficient state for AI usage, with $1 of electricity buying the most ChatGPT prompts — 2,999 in total. In contrast, Hawaii ranks as the most expensive state for AI prompts, with $1 of electricity only allowing for 808 prompts. This wide range highlights how location plays a major role in the cost efficiency of using AI tools.

Made with Flourish

State electricity rates can significantly impact annual costs for heavy AI users. In Hawaii, heavy usage of AI tools like ChatGPT could cost residents an additional $107.14 annually in electricity, far higher than in states with cheaper energy. Understanding these state-specific cost differences is essential for those relying on AI tools regularly, as higher electricity costs can quickly add up, making frequent usage more expensive over time.

The Hidden Costs of AI Prompts

While AI tools offer incredible convenience, our research shows that the energy costs behind each prompt can add up, especially for heavy users. As we use AI more in our daily lives, understanding these hidden costs can help us make smarter choices about our usage. By being mindful of our AI consumption, we can enjoy the benefits of these powerful tools while keeping both our electricity bills and environmental impact in check.
