 The :seedling: **EcoLogits** library tracks the energy consumption and environmental impacts of generative AI models accessed through APIs and their official client libraries. 
 
-It achieves this by **patching the Python client libraries**, ensuring that each API request is wrapped with an impact calculation function. This function computes the **environmental impact based on several request features**, such as the **chosen model**, the **number of tokens generated**, and the **request's latency**. The resulting data is then encapsulated in an `Impacts` object, which is added to the response, containing the environmental impacts for a specific request.
