Lately, Large Language Models have been widely used in code generation. GPT4
is considered the most potent Large Language Model from Openai. In this paper,
we examine GPT3.5 and GPT4 as coding assistants. More specifically, we have
constructed appropriate tests to check whether the two systems can a) answer
typical questions that can arise during the code development, b) produce
reliable code, and c) contribute to code debugging. The test results are
impressive. The performance of GPT4 is outstanding and signals an increase in
the productivity of programmers and the reorganization of software development
procedures based on these new tools.Comment: 10 page
