Abstract

This paper introduces CodeGemma, a family of specialized open code models built on top of Gemma, capable of a variety of code and natural language generation tasks. We release three model checkpoints. CodeGemma 7B pretrained (PT) and instruction-tuned (IT) variants have remarkably resilient natural language understanding, excel in mathematical reasoning, while matching code capabilities of other open models. CodeGemma 2B is a state-of-the-art code completion model designed for fast code infilling and open-ended generation in latency sensitive settings.
