Frequently Asked Questions
Q: What makes this model unique?
StarCoder2-3B combines advanced attention mechanisms with a large context window and efficient architecture, making it particularly effective for code generation while maintaining reasonable resource requirements.
Q: What are the recommended use cases?
The model excels at code completion and generation tasks but is not designed for instruction-following. It's best used for direct code generation with appropriate context rather than natural language commands.
