On Wednesday, Google announced Gemini, a multimodal AI model family it hopes will rival OpenAI's GPT-4, which powers the paid version of ChatGPT. Google claims that the largest version of Gemini exceeds "current state-of-the-art results on 30 of the 32 widely used academic benchmarks used in large language model (LLM) research and development." It's a follow-up to PaLM 2, an earlier AI model that Google hoped would match GPT-4 in capability.

A specially tuned English version of its mid-level Gemini model is available now in over 170 countries as part of the Google Bard chatbot—although not in the EU or the UK due to potential regulation issues.
