Introduction of OpenCoder-1.5B-Code-Chunks-Py

Model Details of OpenCoder-1.5B-Code-Chunks-Py

Description

This model is derived from OpenCoder-1.5B-Base by applying additional context extension fine-tuning. The repository context is composed using the Code Chunks .py composer, more details on which, along with others, can be found in the On Pretraining for Project-Level Code Completion paper. Specifically, Section A.1 of the Appendix describes the context composition method, and Table 3 provides a comparison with other composers from the same collection .

We publish this checkpoint to support the reproducibility and accessibility of our research results.
