The news: In the biggest mass-market AI launch yet, Google is rolling out Gemini, its family of large language models, across almost all its products, from Android to the iOS Google app to Gmail to Docs and more. A new subscription plan will also give users access to Gemini Ultra, the most powerful version of the model, for the first time. Why it matters: ChatGPT, released by Microsoft-backed OpenAI just 14 months ago, changed people's expectations of what computers could do. Google has been racing to catch up ever since and unveiled its Gemini family of models in December. By baking Gemini into its ubiquitous tools, it will be hoping to make up any lost ground, and even overtake its rival.
