CodeT5: Identifier-Aware Unified Pre-training for Program Synthesis and Understanding

CodeT5 is a unified pre-trained encoder-decoder model designed for both understanding and generating code. It's trained on a large dataset of code and natural language, and it's particularly effective because it's aware of identifiers (names given to variables, functions, etc.) in the code. This identifier-awareness helps the model perform better on tasks like translating code from one language to another or summarizing code functionality in natural language.
