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.

The human problem
Developers want coding assistance that can operate near private code and adapt to domain conventions.
The prior constraint
Many capable coding assistants were accessible only through hosted products with limited adaptation or inspection.
AI’s actual role
A transformer trained on source code predicts and generates code, with variants sized for different hardware constraints.
The documented result
BigCode publishes 3B, 7B, and 15B model releases, a fine-tuning example, and links to a code evaluation harness.
Why it may matter
Downloadable variants let teams test privacy, latency, and adaptation tradeoffs directly, while review and testing remain part of software authorship.
Limitations
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.
The project repository establishes model and tooling availability; benchmark results do not establish correctness in a production codebase.

Bright compared this account with the linked original and supporting sources and kept reported, budgeted, projected, and observed claims distinct. Bright did not independently audit the underlying records.
Maturity describes the tested or operational setting. Confidence describes support for the particular claim; one does not determine the other.
