Say It Again: ChatRTX Adds New AI Models, Features in Latest Update

Editor’s note: This post is part of the AI Decoded series, which demystifies AI by making the technology more accessible, and which showcases new hardware, software, tools and accelerations for RTX PC users.

Chatbots powered by large-language AI models have transformed computing, and NVIDIA ChatRTX lets users interact with their local data, accelerated by NVIDIA RTX-powered Windows PCs and workstations. A new update, first demoed at GTC in March, expands the power of this RTX-accelerated chatbot app with additional features and support for new models.

The NVIDIA RTX Remix beta update brings NVIDIA DLSS 3.5 with Ray Reconstruction to the modding platform for even more impressive real-time ray tracing.

Say It Out Loud

ChatRTX uses retrieval-augmented generation, NVIDIA TensorRT-LLM software and NVIDIA RTX acceleration to bring chatbot capabilities to RTX-powered Windows PCs and workstations. Backed by its powerful large language models (LLMs), users can query their notes and documents with ChatRTX, which can quickly generate relevant responses, while running locally on the user’s device.

The latest version adds support for additional LLMs, including Gemma, the latest open, local LLM trained by Google. Gemma was developed from the same research and technology used to create the company’s Gemini models and is built for responsible AI development. ChatRTX also now supports ChatGLM3, an open, bilingual (English and Chinese) LLM based on the general language model framework.

Users can also interact with image data thanks to support for Contrastive Language-Image Pre-training from OpenAI. CLIP is a neural network that, through training and refinement, learns visual concepts from natural language supervision — that is, the model recognizes what it’s “seeing” in image collections. With CLIP support in ChatRTX, users can interact with photos and images on their local devices through words, terms and phrases, without the need for complex metadata labeling.

The new ChatRTX release also lets people chat with their data using their voice. Thanks to support for Whisper, an automatic speech recognition system that uses AI to process spoken language, users can send voice queries to the application and ChatRTX will provide text responses.

Mix It Up

With RTX Remix, modders can transform classic PC games into RTX remasters using AI-accelerated tools on the NVIDIA Omniverse platform.

Now, they can use DLSS 3.5 with Ray Reconstruction in their projects with just a few clicks, thanks to an update to RTX Remix available this week. Its advanced, AI-powered neural renderer improves the fidelity, responsiveness and quality of ray-traced effects, giving NVIDIA GeForce RTX gamers an even better experience.

AI powers other elements of the Remix workflow, too. Modders can use generative AI texture tools to analyze low-resolution textures from classic games, generate physically accurate materials — including normal and roughness maps — and upscale the resolution by up to 4x. Tools like this also save modders time, quickly handling a task that could otherwise become tedious.
