Nvidia has enhanced its AI chatbot, formerly known as 'Chat with RTX', now ChatRTX, with significant updates including support for Google's Gemma model, voice queries, and additional large language models (LLMs) such as ChatGLM3 and OpenAI's CLIP. The update, which is available for download today, also introduces improved photo search and AI speech recognition capabilities. To utilize ChatRTX, users will require an RTX 30- or 40-series GPU, and the software runs locally on a Windows PC.
