AI-Powered Code: Efficiency vs. Carbon Footprint
Large language models (LLMs) are used in software development to assist in various tasks, e.g., code generation and code completion, but empirical evaluations of the quality of the results produced by these models focus on correctness and ignore other relevant aspects, such as their performance and energy efficiency. Studying the performance of LLM-produced programs is essential to understand how well LLMs can support the construction of performance- and energy-critical software, such as operating systems, servers, and mobile applications.

Highest C++ Energy Increase (Ubuntu, GitHub Copilot relative to baseline)
Just training BLOOM, a 176B parameter language model, required an estimated 689,842 KWh, approximately the energy consumed by 1000 Tesla Model 3 cars running for almost 5,000 km each. Its training emitted an estimated 24.7 tonnes of CO2, the emissions of a 737 flying between Rome and London with 100 passengers. However, by generating energy-efficient code, LLMs have potential to reduce the carbon footprint, especially for compute-intensive tasks.

Language Impact on Efficiency
LLMs perform optimally in Python, achieving the highest pass@1 accuracy. Python solutions, in some instances, exhibiting greater energy efficiency than human-written. Java and C++ solutions generally show increased energy consumption compared to the baseline, with C++ showing the most pronounced increase.
Algorithm & Data Structure Performance
String, Tree, Hashing, and Search algorithms consistently show strong performance with LLM-generated code. Challenges persist in Sorting, Graph, Greedy algorithms, Math, and Recursion, resulting in more energy-demanding solutions, especially for Java and C++.
LLM Model Differences & Energy Footprint
OpenAI 01-mini shows significant improvements in accuracy, particularly in Search algorithms and Sorting, but generally exhibits higher energy consumption compared to GPT-40 and GitHub Copilot. GitHub Copilot is often the most energy-efficient for Python and Java, while GPT-40 performs best for C++.
Cross-Platform Consistency
LLM-generated solutions are machine-agnostic, showing strong energy correlations across systems (Ubuntu vs. macOS). Human-written solutions, however, appear optimized for specific machines, resulting in lower correlations for C++.

Case Study: First Missing Positive Problem
Problem Description: The 'First Missing Positive' problem requires identifying the smallest positive integer missing from a given unsorted integer array nums. This problem is classified as 'Hard' on LeetCode due to its constraints on time and space complexity.
Human Solution: The best human-written solution typically achieves O(n) time complexity by using array manipulation (e.g., modulus and division operations) to mark visited numbers in-place. While efficient, these operations can lead to higher computational overhead in each iteration, potentially processing the list around 2.5 times.
LLM Solution (OpenAI 01-mini): OpenAI 01-mini's solution initially appears O(n²) but leverages an in-place swapping technique, efficiently positioning elements. The number of iterations within the nested loop is relatively low, traversing the list approximately 1.5 times, with swaps occurring sporadically. This approach often results in energy efficiency closely approximating human-written solutions, or even surpassing them in certain scenarios due to fewer complex arithmetic operations per iteration.
