Making improvements one step at a time for Marble. In the case of generating bigger worlds, it's quite literal ;) 🤩🌐

World Labs@theworldlabs

We're excited to be rolling out two model updates today!

Marble 1.1: Improves lighting and contrast, with a major reduction in visual artifacts.

Marble 1.1-Plus: Our new model built for scale. Create larger, more complex environments than ever before.

Most VLM benchmarks watch the world; few ask how actions *change* it from a robot's eye.

Embodied cognition tells us that intelligence isn't just watching – it's enacted through interaction.

👉We introduce ENACT: A benchmark that tests if VLMs can track the evolution of a home-scale environment from a robot's egocentric view.

Lenny Rachitsky@lennysan

Dr. Fei-Fei Li (@drfeifei) is known as the “godmother of AI.”

For the past two decades, she’s been at the center of AI’s most significant breakthroughs, including:
- Spearheading ImageNet, the dataset that sparked the AI explosion we’re living through right now.
- Leading  work at Stanford Artificial Intelligence Laboratory (SAIL)
- Serving as Chief Scientist of AI/ML at Google Cloud
- Co-founding Stanford’s Institute for Human-Centered AI
- Serving on the United Nations AI Scientific Advisory Board
- Being named as Time's 100 most influential people in AI

In this conversation, Fei-Fei shares the rarely told history of how we got to today—and what comes next.

We discuss:
🔸 The backstory on ImageNet
🔸 Why robotics faces unique challenges compared with language models and what’s needed to overcome them
🔸 Why Fei-Fei believes AI won’t replace humans but will require us to take responsibility for ourselves
🔸 Why world models and spatial intelligence represent the next frontier in AI, beyond large language models
🔸 The surprising applications of Marble, from movie production to psychological research
🔸 How to participate in AI regardless of your role
🔸 Much more

From AI empowered education reforms, to the future of jobs, from spatial intelligence to robotics, it was fun to spend my alumni reunion Saturday with alums from all over the world and my friend @lilysarafan , chair of @Stanford board of trustees. Go Cardinal! @StanfordHAI

Very excited to share @theworldlabs ‘s latest research work RTFM!! It’s a real-time, persistent, and 3D consistent generative World Model running on *a single* H100 GPU! Blog and live demo are available below! 🤩

Generative World Models will inevitably be computationally demanding, potentially scaling beyond even the requirements of today’s LLMs. But we believe they are a crucial research direction to explore in the future of rendering and spatial intelligence.

Total insanity. This is using an adaptive LOD scheme in sparksjs (not merged yet). The entire scene has 16million splats and this is real time navigation ... 😱😱

Some of the large scene's being generated are really unbelievable. This is a generative 3D splat, not 2D video. 

The full scene is likely over 50million splats. You can see some stitching inconsistencies from the final v2v pass. Also nice music :)
