This is something you should know about, use, and understand how works, probably in that order. https://twitter.com/dan_fried/status/1514265047761043456 https://sites.google.com/view/incoder-code-models InCoder InCoder: A Generative Model for Code In-Filling and Synthesis Daniel Fried*, Armen Aghajanyan*, Jessy Lin, Sida Wang, Eric Wallace, Freda Shi, Ruiqi Zhong, Wen-tau Yih, Luke Zettlemoyer, and Mike Lewis arXiv, 2022 Paper: https://arxiv.org/abs/2204.05999 Demo: https://huggingface.co/spaces/facebook/incoder-demo Model weights and instructions: https://github.com/dpfried/incoder/blob/main/README.md Examples: https://sites.google.com/view/incoder-code-models/home/examples Inserting and completing code in a single model We train a generative, decoder-only Transformer using a causal-masking training objective (from CM3, Aghajanyan et al. 2022) , which trains a model to generate entire code files in arbitrary orderings via masking. Here's an example where a single region is masked: Zero-shot generation for code tasks In inference, we can prompt our model with a document containing MASK tokens where we want it to insert code. This lets us perform a plethora of code tasks without any task-specific fine-tuning, including docstring generation, type hint prediction, variable renaming, cloze tasks, and more. Here are real outputs from our model: See more examples here: Examples Trained on open-source code and StackOverflow Unlike past work, our model's training data consists of only permissively-licensed code (Apache 2.0, MIT, BSD-2 and BSD-3 licensed) from online sources such as GitHub and GitLab, as well as StackOverflow. We focus on Python and JavaScript, but include 28 languages in total -- a total of ~200GB of data (after deduplication, filtering, and decontamination). See our paper for details.
