CodeGenX is a code generation system powered by Artificial Intelligence which is delivered to you in the form of a Visual Studio Code Extension. It is free and open-source! Currently, it only supports Python but we are planning to add additional languages in future releases. The core of CodeGenX lies in its large neural network called GPT-J which was trained on hundreds of gigabytes of text from the internet. This model has been further fine tuned with an open source library for python code, allowing it to generate high quality code when given the right instructions.
