A former Nvidia researcher explains how xAI built Grok Imagine in three months, revealing the training pipeline of video generation models, the definition of world models, and the future trends of Video Agents.

Grok 5 remains under training as of May 2026, with Musk stating it may be indistinguishable from AGI and a ~10% chance of human-level intelligence; XAI built Colossus 2—a 1-GW cluster with ~500k GPUs in 122 days—while facing environmental lawsuits and losing 10 of 11 co-founders.

xAI and Cloudflare partner to bring Grok models to Cloudflare AI Gateway, allowing users to pay directly through Cloudflare without additional authentication, environment, or API keys.

AI video agents will follow the same trajectory as coding agents, with Grok Imagine achieving a zero-to-one breakthrough through real-time interactive world models and generative UI, leading to future video generation driven by intelligent agents with cameras, editors, and tool belts rather than text prompts.

AI video generation is following a similar evolution path as coding agents, with Grok Imagine demonstrating a leap from zero to one; future systems will evolve into interactive agents with cameras, editors, and tool belts, rather than simple prompt boxes.

Third Point founder Dan Loeb argues AI is reshaping investment logic: investors must grasp the AI Stack (power → chips → models → applications); credit expertise is critical in volatile markets; his $25B multi-asset platform coordinates equities, credit, insurance, and private markets via strategies like Fulcrum Security; activist investing succeeds through governance reform, not confrontation.

AI has not triggered the predicted 'job apocalypse'; OpenAI’s Sam Altman and Anthropic’s Dario Amodei recently revised their earlier dire forecasts, admitting their job-impact predictions were overly pessimistic; in practice, AI boosts individual productivity but does not reduce total workload—instead enabling more high-leverage tasks and new roles.

The article criticizes Bernie Sanders' proposed AI sovereign wealth fund plan, arguing that its one-time 50% equity tax on AI companies is essentially wealth confiscation, and the proposal for government control of companies poses significant risks such as power concentration, while also deeming the moral foundation of the plan insufficient to justify such aggressive taxation.

Replicate partners with XAI to release the ultimate prompting guide for Grok Imagine Video 1.5, covering best practices and tips for video generation.

Ethan He shared in the Latent.Space podcast that video generation models derive most intelligence from language, not video data; idea-to-code is fast now, but backend development remains a bottleneck, with future frontiers focusing on world models, continual learning, and agents.
