LTX released LTX-2.5, an open-weights video world model optimized for local generation on NVIDIA RTX GPUs and DGX Spark. A 10-second clip runs in 6.8 seconds on-prem, compared with 23.7 seconds via the LTX API. Native multishot generation, a Gemma 4 backbone, and a new high-motion decoder aim to make campaign-ready, consistent sequences usable locally inside ComfyUI, reducing reliance on cloud or studio workflows.
Nvidia launched Nemotron 3.5 Lightning and NeMo Switchyard, an open-source library for routing between models in AI systems. Nemotron 3.5 Lightning is a 30-billion-parameter mixture-of-experts model that Nvidia says can produce up to 4x faster outputs. The releases aim to make it easier to customize small models via post-training and lower task-completion costs by having model routers choose the right model per workflow.
Meta tied a superintelligence manifesto to the release of Muse Glimmer, an open-weight AI agent model. The model is roughly 30-billion-parameter, and users can download it to run locally and customize it. This shifts the competition toward ownership and local control of agents rather than renting model access, while critics argue it also raises safety risks as autonomy spreads.
Meta released Muse Glimmer, an open-weights 30B dense multimodal agent model under Apache 2.0, and said Muse Spark weights will be released “soon” after Zuckerberg’s personal superintelligence essay. The Glimmer serving stack targets keeping the model under 20GB via quantization and is positioned for local on-device agent loops. This shifts Meta’s push toward broadly available personal superintelligence by expanding open, locally deployable AI options and adding an imminent follow-on weights release.
