About StarCoder2 15B

StarCoder2 15B, developed by Hugging Face in collaboration with ServiceNow and NVIDIA as part of the BigCode initiative, is an open-source code model with 15 billion parameters and a 16K token context window. The model was trained on The Stack v2, a curated dataset of over 619 programming languages sourced from permissively licensed repositories. StarCoder2 excels at code completion, generation, explanation, and bug detection. It achieves strong scores on HumanEval and MBPP coding benchmarks, competing with larger proprietary coding models. Free and open-source under a responsible AI license, it supports commercial use with ethical guidelines. The model represents a community-driven approach to AI development, with transparent data sourcing and governance. It has become a foundation for open-source coding assistants and IDE integrations across the developer tools ecosystem.
