NVIDIA led open-source AI model releases with Cosmos 3, a comprehensive omnimodal world model unifying language, image, video, audio, and action using a Mixture-of-Transformers design, and Nemotron 3 Ultra, a 550B parameter open-weight model noted for high serving speed and strong evaluation performance. The Cosmos Coalition was launched to foster an open ecosystem for physical AI world models. Meanwhile, MiniMax M3 debuted as a multimodal agent/coding model with 1M context and strong benchmark scores, gaining rapid ecosystem support from vendors like Novita and Vercel AI Gateway. However, MiniMax M3 showed some inefficiencies such as high token consumption and verbose self-check loops. These developments highlight advances in open physical AI, multimodality, and agent models with significant community and infrastructure engagement.
