Model Summary

This is the same model as SantaCoder but it can be loaded with transformers >=4.28.1 to use the GPTBigCode architecture. We refer the reader to the SantaCoder model page for full documentation about this model

• Repository: bigcode/Megatron-LM
• Project Website: bigcode-project.org
• Paper: 🎅SantaCoder: Don't reach for the stars!🌟
• Point of Contact: contact@bigcode-project.org
• Languages: Python, Java, and JavaScript

There are two versions (branches) of the model:

• main: Uses the gpt_bigcode model. Requires the bigcode fork of transformers.
• main_custom: Packaged with its modeling code. Requires transformers>=4.27. Alternatively, it can run on older versions by setting the configuration parameter activation_function = "gelu_pytorch_tanh".

Use

Intended use

The model was trained on GitHub code. As such it is not an instruction model and commands like "Write a function that computes the square root." do not work well. You should phrase commands like they occur in source code such as comments (e.g. # the following function computes the sqrt) or write a function signature and docstring and let the model complete the function body.

Attribution & Other Requirements

The pretraining dataset of the model was filtered for permissive licenses only. Nevertheless, the model can generate source code verbatim from the dataset. The code's license might require attribution and/or other specific requirements that must be respected. We provide a search index that let's you search through the pretraining data to identify where generated code came from and apply the proper attribution to your code.

Limitations

The model has been trained on source code in Python, Java, and JavaScript. The predominant language in source is English although other languages are also present. As such the model is capable to generate code snippets provided some context but the generated code is not guaranteed to work as intended. It can be inefficient, contain bugs or exploits.
