About CodeT5

Open-source transformer model for code tasks like generation and summarization.

CodeT5 is an open-source AI model developed by Salesforce Research for various code understanding and generation tasks. Built on top of the T5 (Text-to-Text Transfer Transformer) framework, CodeT5 is designed to handle programming-related problems such as code summarization, generation, translation between programming languages, and code completion. It supports multiple programming languages and has been trained on large datasets from GitHub repositories. Since it is a research-focused model, CodeT5 is generally used in experimental setups, research labs, and academic environments. It is available as a Hugging Face model and can be fine-tuned or integrated into custom applications. CodeT5 does not have a commercial hosted offering but can be deployed in local environments or research servers. Developers and researchers often extend it for specific language tasks, and it is praised for its explainability and code-oriented structure.
