The search maybe. Saying "please" is a tiny part of that.
According to ChatGPT: 😉
For a typical ChatGPT-style query, adding "please" and "thank you" might add a handful of extra tokens (roughly 2–5 words each). The energy used by an AI model is approximately proportional to the amount of text it processes and generates, so those extra words do have a cost, but it's tiny.
As a rough illustration:
"What's the capital of France?" → perhaps 6–8 input tokens.
"Please could you tell me what the capital of France is? Thank you." → perhaps 15–20 input tokens.
The second version might use roughly twice the input processing energy, but the response generation usually dominates the total cost. If the AI generates a 100-word answer, those extra few input words are a very small fraction of the overall computation.
Some estimates suggest that a typical AI query uses energy comparable to:
running an LED light bulb for a few minutes,
or making a few web searches,
depending on the model and data centre.
Adding "please" might increase that by well under 1% for a normal conversation.
So from an environmental perspective, you should feel free to be polite. The biggest drivers of AI energy use are:
Long conversations.
Very large outputs.
Complex reasoning tasks.
Image and video generation.
A single "please" is essentially a rounding error. 😊
