Remarkable Efficiency Gains

Google's commitment to improving AI efficiency has yielded impressive results. Over a 12-month period, the company achieved substantial reductions in both energy consumption and carbon footprint for its Gemini Apps text prompts:

• Median energy consumption decreased by a factor of 33x
• Carbon footprint reduced by a factor of 44x

These improvements were achieved while simultaneously enhancing the quality of responses, demonstrating that efficiency and performance can go hand in hand 1

Putting Energy Consumption into Perspective

To contextualize the energy efficiency of their AI models, Google provided a relatable comparison. According to their recent analysis, the energy consumed per median prompt is equivalent to watching television for less than nine seconds. This analogy helps to illustrate the significant strides made in reducing AI's energy footprint 1
