[AINews] NVIDIA Cosmos 3, Nemotron 3 Ultra, and RTX Spark
NVIDIA launched Cosmos 3, Nemotron 3 Ultra, and previewed the RTX Spark superchip at Computex.
NVIDIA released Cosmos 3, a Mixture-of-Transformers model unifying language, image, video, audio and action whose Super finetunes are new SOTA open-weights image/video generators, alongside Nemotron 3 Ultra (550B-A55B), a new US SOTA open-weights LLM. It also previewed the RTX Spark 1-petaflop personal superchip with Microsoft, OpenClaw, and Nous Research as launch partners. The wave of competitive open-weights frontier models and edge hardware marks a significant shift in NVIDIA's positioning beyond chips into the model layer.
