Google DeepMind released Genie 3 this past week. It's a world model that can simulate interaction environments with a single prompt.
World models are the breakthrough AI agents need to become useful and adapt to new situations quickly. I've heard a lot of complaints recently about the usefulness and usability of AI agents being overstated by AI companies and world models solve a key limitation to enable further use cases.
World models like Genie 3 are a breakthrough because they are "make it possible to train AI agents in an unlimited curriculum of rich simulation environments." This means we can procedurally generate the environments we need to train AI agents on a variety of tasks.
One of the huge limitations of AI agents currently is they need the data to train on a scenario to be useful in that scenario. Examples of this include self-driving cars, robotics, or digital games. This limitation is applicable to any physical AI that needs to interact with an environment.
This is an area we're critically lacking in data and a big reason why the agents we see deployed today can be considered "glorified chat bots". We have the language data to create the chat bots. We lack the data for other types of agents.
Genie 3 works by receiving a text description from the user describing a scene. It then creates a 720p environment running at 24 frames per second that can be navigated and interacted with. The model maintains visual consistency for several minutes and remembers what happened up to a minute ago.
World models enable:
Generating training scenarios by describing them.
Testing systems in conditions that would be expensive or dangerous to create in reality.
Creating variations of scenarios quickly without building new simulations.
Training agents on edge cases and rare events that are hard to capture in real data.
Simulating complex multi-agent interactions without coordinating real participants.
Prototyping and validating ideas before investing in expensive real-world testing.
A good example of this usability is autonomous vehicle testing. Instead of driving millions of miles or building complex simulations, thousands of scenarios can be generated: heavy rain at night, construction zones, emergency vehicles, pedestrians in different lighting conditions.
World models are still in their early research days and have key limitations:
Generated scenarios may not accurately reflect real-world physics and constraints.
Models can hallucinate impossible or inconsistent behaviors.
Quality degrades significantly for scenarios outside the (world model) training distribution.
Computational requirements are enormous for high-fidelity simulations.
Current models struggle with long-term consistency and cause-effect relationships.
Limited ability to model complex systems with many interacting components.
Genie 3 is currently only available to a small group of researchers, but the proven concept represents a shift in how we can think about AI training infrastructure. World models are positioning themselves as foundational technology similar to how transformers became the backbone of language models.
On a side note, they also enable automated video game and movie generation. Think of movie and game experiences personalized for each individual and generated in real-time. Theoretically, a game or movie a person enjoys could never end. The sequel could just be generated.
This brings me to a question I have for you: Do you think fully AI-generated feature films or AAA games will come first? Let me know in the comments.

We learned about the importance of capturing feedback directly from users and the impact iterating quickly has. Check it out and enjoy the resources below!
Must-reads
1. OpenAI releases open models
OpenAI just dropped their first open models—GPT-OSS-120B for datacenters and GPT-OSS-20B for local machines. Reviews so far seem positive. This is a big step in open source and shows OpenAI was serious about their promise.
2. My 2.5-year-old laptop can write Space Invaders
Simon Willison demonstrates his MacBook Pro M2 running GLM-4.5 Air locally via MLX generating a complete, working Space Invaders game in HTML and JavaScript on the first try. Peak memory usage was around 48GB on consumer hardware.
3. Three challenges in machine-based reasoning
Amazon's research team breaks down the core problems in automated reasoning: translating natural to structured language, defining truth, and achieving definitive reasoning. If you're building AI systems, understanding these fundamental challenges is important.
4. I know when you're vibe coding
AI-generated code is easy to spot because it frequently doesn't follow project conventions. Learn to spot redundant implementations, inappropriate architectural choices, and other telltale signs that code was generated for speed over quality.
5. Gemini Embedding model
Google's Gemini Embedding text model is now generally available for building advanced AI applications. The model achieved over 81% correct answers in evaluations and showed a 3.6% recall increase, making it useful for RAG and context engineering applications.

This week's jobs
Three trends this week:
ML engineering positions are rampant.
Remote opportunities actually seem to be increasing.
New grad/junior AI positions are popping up much more frequently. I'm very surprised by this one, but it makes sense. There's far more demand than supply in AI so companies will find more candidates by teaching them instead of hiring them.
Graduate Opportunities:
TikTok - Multiple ML Engineer Graduate positions (San Jose, Seattle) focusing on e-commerce search, recommendation systems, and multimodal matching for video content
Quora - Remote ML Engineer New Grad working on Poe's cutting-edge LLM applications with end-to-end ownership
Nuro - AI Platform Software Engineer New Grad in Mountain View
Experienced Roles:
X, The Moonshot Factory - ML Engineer for early-stage moonshot projects in Mountain View
Netflix - L5 ML Engineer for Studio Media Algorithms
Notion - Software Engineer, Machine Learning in San Francisco
Yahoo - ML Engineer (Remote)
