Reka AI's Rho-1 is a 19-billion-parameter omni-model that processes and generates text, images, video, and robot control actions in a single neural network. Trained on 320 H100 GPUs in about three months, it uses a fraction of the compute today's top models need. Instead of routing tasks to specialized systems, Rho-1 runs all modalities as tokens in one shared context window.

Runway, one of the best-known developers of generative AI video technology, is moving into robotics with Praxis-1, an open-weight AI model designed to use knowledge learned from video to control physical robots. “Open-weight” means developers can download the model and run or adapt it themselves, rather than only accessing it through Runway’s servers. The company […]

Everyone in the world-models space is sitting on a pile of cash and a ton of buzz, but good luck getting anyone — from the founders to their own data suppliers — to tell you what they're actually building.

LTX has launched LTX-2.5, the latest version of its open-weights world model, introducing new capabilities for video generation, real-time applications and physical AI. The company says the new model delivers improvements in visual quality, prompt understanding, generation speed and efficiency, while allowing developers and enterprises to run and customize the model on their own hardware.
