About
The DeciCoder family consists of open-source large language models (LLMs) focused on code generation, developed by Deci AI. These models leverage Deci's proprietary AutoNAC technology to optimize their architecture for enhanced accuracy and speed 52. The flagship model, DeciCoder-1b, features 1 billion parameters and is specifically designed for code completion tasks. Trained on subsets of the Starcoder Training Dataset, it supports languages like Python, Java, and JavaScript and is equipped with Grouped Query Attention and a 2048-token context window 2. Designed to efficiently generate accurate code, DeciCoder models offer cost savings by running effectively on more affordable hardware, with plans for expanding the model lineup 53.
