Chrome is experimentally shipping with Gemini Nano, their smallest Large Language Model (LLM) baked right in, then offer APIs to use it. In Chrome, these APIs are built to run inference against Gemini Nano with fine-tuning or an expert model. Designed to run locally on most modern devices, Gemini Nano is best for language-related use […]
