Adapting a code model to a private codebase
StarCoder2 offers several downloadable code-model sizes plus fine-tuning and evaluation examples for local completion and generation experiments.
- AI’s role
- A transformer trained on source code predicts and generates code, with variants sized for different hardware constraints.
- Documented result
- BigCode publishes 3B, 7B, and 15B model releases, a fine-tuning example, and links to a code evaluation harness.
- Important limitation
- Generated code can be insecure, incorrect, or incompatible with a project. Repository code is Apache-2.0, while StarCoder2 model weights use BigCode OpenRAIL-M v1; dataset provenance and terms remain separate.
