I run qwen 27b at home when working it pulls around 400W. I get 40ish tokens per second generation and more importantly about 1000 tokens per second prompt processing.

In an hour it can process 3.6 million tokens or generate 144000 tokens. This costs me about 15 cents given my electricity prices.

For sonnet the equivalent token costs are 7.2 dollars for the prompt processing or 1.4 dollars for the generation. The cloud is 10x more expensive for generation and close to 50 times more expensive for processing.
