Recent discussions have highlighted concerns over the energy consumption of AI models like ChatGPT, with some estimates suggesting that each query consumes approximately 3 watt-hours (Wh) of electricity. This figure, often cited to underscore the environmental implications of AI technologies, has been a focal point in debates about sustainable AI development.
However, recent analysis may challenge this prevailing notion.
By incorporating updated data and refined assumptions, a study from Epoch AI estimates that a typical ChatGPT query using the GPT-4o model consumes about 0.3 Wh – significantly lower than earlier projections. This reduction is attributed to advancements in model efficiency and hardware improvements since early 2023.
Why It Matters: Understanding the true energy consumption of AI models is crucial for assessing their environmental impact and guiding sustainable development practices. Overestimations can lead to unnecessary alarm, while underestimations might result in complacency. Accurate assessments ensure that stakeholders can make informed decisions about AI deployment and its ecological footprint.
- Previous Estimates: Earlier reports suggested that each ChatGPT query consumed around 3 Wh of electricity, approximately ten times the energy required for a standard Google search. These figures were often used to highlight the environmental concerns associated with AI usage.
- Revised Calculations: Epoch AI’s recent analysis revisited these estimates using up-to-date information and clearer assumptions. The study concluded that a typical ChatGPT query consumes approximately 0.3 Wh, a tenfold decrease from prior estimates.
- Factors Contributing to the Reduction: The significant decrease in estimated energy consumption is attributed to more efficient AI models and advancements in hardware since early 2023. Additionally, previous estimates may have overestimated the number of tokens processed per query, leading to inflated energy consumption figures.
- Contextualizing the Energy Use: To put 0.3 Wh into perspective, it’s less than the energy consumed by an LED lightbulb or a laptop in a few minutes. Even for heavy users, the energy cost of ChatGPT constitutes a minimal fraction of the daily electricity consumption of an average household.
- Considerations for Future Models: While current energy consumption per query is relatively low, it’s important to note that future AI models, especially those with longer input or output lengths or advanced reasoning capabilities, may require more energy. Continuous monitoring and optimization are essential to maintain sustainable AI practices.
