What is CodeBERTa-small-v1?
CodeBERTa-small-v1 is a specialized code understanding model based on the RoBERTa architecture, specifically trained on the CodeSearchNet dataset. It's designed to process and understand source code across six programming languages: Go, Java, JavaScript, PHP, Python, and Ruby. The model utilizes a Byte-level BPE tokenizer that achieves 33-50% shorter sequences compared to standard GPT-2/RoBERTa tokenizers when processing code.
Implementation Details
The model features a 6-layer transformer architecture with 84M parameters, matching DistilBERT's layer configuration. It was trained from scratch for 5 epochs on approximately 2 million functions from various programming languages.
- Efficient code tokenization with specialized BPE tokenizer
- Optimized for masked language modeling in code contexts
- Supports multiple programming languages in a single model
- Trained on a diverse dataset of real-world code examples
Core Capabilities
- Masked language modeling for code completion
- Programming language identification
- Code understanding across 6 programming languages
- Efficient sequence encoding for code-specific tasks
