InCoder: A Generative Model for Code Infilling and Synthesis

InCoder is a cutting-edge generative model designed for code infilling and synthesis, developed by a team of researchers including Daniel Fried and others. This model leverages the power of large language models to assist developers in writing code more efficiently and effectively.

Overview

InCoder is hosted on GitHub and utilizes HuggingFace's transformers library, making it accessible for developers looking to enhance their coding capabilities. The model comes in two sizes: a 6.7 billion parameter model and a smaller 1.3 billion parameter model, allowing users to choose based on their computational resources and needs.

Core Features

• Generative Code Infilling: InCoder can intelligently fill in gaps in code, making it easier for developers to complete their projects.
• Synthesis Capabilities: The model can generate new code snippets based on provided context, aiding in rapid prototyping and development.
• Custom Tokenizer: InCoder uses a custom tokenizer that supports left-padding, ensuring that the model processes inputs effectively.

Getting Started

To start using InCoder, follow these steps:

1. Installation: Ensure you have the required libraries installed:

   pip install torch
   pip install 'tokenizers>=0.12'
   pip install transformers
   

2. Load the Model: You can load the model and tokenizer as follows:

   from transformers import AutoTokenizer
   tokenizer = AutoTokenizer.from_pretrained("facebook/incoder-1B")  # or "facebook/incoder-6B"
   tokenizer.pad_token = "<pad>"
   tokenizer.padding_side = "left"
   

3. Usage: Check out the example_usage.py for a demo script that showcases how to use the infilling capabilities of the model. Set BIG_MODEL = True to utilize the 6.7B parameter model.

Pricing

InCoder is open-source and available for free on GitHub. However, users should check the repository for any updates regarding licensing and usage terms.

Practical Tips

• Tokenization: When decoding, remember to set clean_up_tokenization_spaces=False to maintain proper spacing in your output.
• Batch Processing: For projects requiring batch generation, refer to example_batched_usage.py for guidance.

Competitor Comparison

InCoder stands out among other code generation tools due to its advanced generative capabilities and the backing of HuggingFace's robust infrastructure. While tools like OpenAI's Codex also provide code generation features, InCoder's focus on infilling and synthesis offers unique advantages for developers looking to streamline their coding process.

FAQs

• What programming languages does InCoder support?
  InCoder is designed to work with multiple programming languages, but its effectiveness may vary based on the language and context provided.
• Is there a demo available?
  Yes, a demo of the 6.7B model is available on HuggingFace Spaces, although it may be temporarily unavailable at times.

Conclusion

InCoder is a powerful tool for developers looking to enhance their coding efficiency through generative AI. With its unique features and open-source availability, it is worth exploring for anyone involved in software development.
