xAI Grok Imagine API - the #1 Video Model, Best Pricing and Latency - and merging with SpaceX

**Google DeepMind** launched **Project Genie (Genie 3 + Nano Banana Pro + Gemini)**, a prototype for creating interactive, real-time generated worlds from text or image prompts, currently available to **Google AI Ultra subscribers in the U.S. (18+)** with noted limitations like **~60s generation limits** and imperfect physics. In parallel, the open-source **LingBot-World** offers a real-time interactive world model with **<1s latency at 16 FPS** and minute-level coherence, emphasizing interactivity and causal consistency. In video generation, **xAI Grok Imagine** debuted strongly with native audio support, **15s duration**, and competitive pricing at **$4.20/min including audio**, while **Runway Gen-4.5** focuses on animation workflows with new features like **Motion Sketch** and **Character Swap**. The 3D generation space sees **fal** adding **Hunyuan 3D 3.1 Pro/Rapid** to its API offerings, extending model-as-a-service workflows into 3D pipelines.
