This translates to about 18 TWh per year, Residential electricity used by Mississippi, USA, in a yearin the United States. According to the KISTEP report, ChatGPT consumes 226.8 GWh of electricity per year, which is about the same as the Full day's electricity for a country like Finland or Belgiumcorresponds to.
💡 â Note: OpenAI CEO Sam Oltman recently called for a moratorium on the popularity of image conversion features, saying that “GPUs are melting down”. It's a stark reminder of how serious AI's power consumption can be.
Two sources of AI power consumption
AI's power consumption is largely Training과 Inference It is divided into two phases. In the past, the training phase consumed the bulk of the power, but in recent years, providing real-time inference to hundreds of millions of users has made the Spikes in power load at all timesin the following example.
3Power consumption of training AI models
As deep learning models have exploded in size, the amount of computation and power required during the training process has grown exponentially. GPT-3 (175 billion parameters) Approximately 1,287 to 1,300 MWh per training runwhich is consumed by the Annual electricity consumption for 120-130 U.S. homesof electricity. Compare that to one hour of Netflix streaming (0.8 kWh), which is equivalent to about 1.65 million hours of viewing.
AI training power consumption characteristics
- Model Scale: Power consumption spikes proportional to parameter increase
- Duration of study: Requires weeks to months of continuous operation
- GPU ClustersThousands to tens of thousands of AI chips running concurrently
- Cooling Load: Additional power consumption due to heat generation
Major model training power
- GPT-3: Approx. 1,287 MWh (120 households/year)
- GPT-4: Estimated 5.8 times more than GPT-3
- After GPT-5: requires larger computations and longer learning curve
- DeepSeek R1: 401 TP3T increase in demand despite 701 TP3T increase in efficiency
4Always-on power load for AI Inference
As AI services become more popular Power consumption in the inference phase is trending beyond the learning phase. With hundreds of millions of users asking AI questions in real-time, around the clock, and generating responses to those questions, massive amounts of power are consumed at all times. AI data centers, in particular, need to be able to run on Demand 24/7 availability, low idle rates, and low latencywhich makes the ‘power-performance tradeoff" very difficult.
| Separation | Training | Inference |
|---|---|---|
| Consumption patterns | Intensive, short-term | Always on, Continuous |
| Power Characteristics | Ultra-high power, peak load | High power, baseload |
| Scalability | Once per model | Proportional to the number of users |
| Looking ahead | Increase to larger models | Spike with service proliferation |
