Gemma 2 is the next-generation Google Gemma model, boasting 27 billion parameters and delivering performance comparable to Llama 3 70B, while maintaining half its size. It's optimized to run efficiently on NVIDIA GPUs or a single TPU v4 host on Vertex AI, reducing deployment costs and making it accessible to a wider user base. Gemma 2 also provides a robust toolkit for fine-tuning, supporting both cloud solutions and community tools like Google Cloud and Axolotl, along with seamless partner integration with Hugging Face and NVIDIA TensorRT-LLM.
