Dreamer 4 Trains Agents Inside Scalable World Models
Researcher Danijar Hafner and team just unveiled Dreamer 4, and it's rewriting the rules on how AI agents learn complex tasks. Dreamer 4 learns entirely inside its own world model, never touching the actual environment until evaluation.
It's actually the first agent to mine diamonds in Minecraft using only offline data. No trial and error, no learning from mistakes in the real game—just pure imagination training. And it crushes the competition while doing it.
What makes Dreamer 4 a research breakthrough:
Imagination training replaces environment interaction: Dreamer 4 practices behaviors through reinforcement learning inside its world model, a process the researchers call "imagination training." This is critical for fields like robotics where letting an AI experiment in the real world isn't practical or safe. The agent successfully completes the diamond mining task, which requires choosing sequences of over 20,000 mouse and keyboard actions from raw pixels.
100x more data efficient than OpenAI's approach: On the offline diamond challenge, Dreamer 4 significantly outperforms OpenAI's VPT offline agent while using 100 times less data. It also beats modern behavioral cloning approaches that rely on finetuning powerful vision-language models like Gemma 3. The research shows the world model provides better representations for decision making than general-purpose foundation models.
Real-time interactive inference on a single GPU: Through a new objective and architecture, Dreamer 4 achieves real-time interactive inference on consumer hardware.
So What?
This research essentially means agents will can learn complex behaviors without expensive or dangerous real-world interaction. For robotics, autonomous systems, and any domain where trial-and-error learning isn't feasible, world models like Dreamer 4 offer a path forward.
The fact that it achieves this on a single GPU while outperforming methods trained on 100x more data suggests we're entering an era where intelligent behavior can be learned more efficiently through simulation than through direct experience. The researchers note this is "a significant step towards intelligent agents," and the early results suggest they might be right…

OpenAI Launches Sora 2 With Its Own TikTok-Style App
OpenAI just released Sora 2 and simultaneously launched a standalone mobile app that looks suspiciously like TikTok.
It's a bold move that puts OpenAI in direct competition with social media giants, turning their text-to-video model into a content creation and discovery platform. Whether you see it as innovation or invasion probably depends on how you feel about OpenAI's expanding empire…
Key details on the Sora 2 release:
The updated model generates higher quality videos with better motion, temporal consistency, and understanding of complex prompts. OpenAI claims significant improvements in realism and the ability to handle more detailed instructions (the physics are incredible)!
Available on iOS, the standalone app features a vertical scrolling feed where users can discover AI-generated videos, create their own content, and interact with a community of creators. It's designed for content consumption and creation in one package.
At the time of writing, you still need an invite code to use the Sora app. OpenAI is rolling out access gradually, likely to manage compute costs and gather feedback before opening the floodgates.
So What?
OpenAI is making a calculated bet that AI-generated content will become a dominant form of social media, and they want to own that platform from day one.
The TikTok-style format suggests they're not targeting professional video editors; they're going after mainstream social media users. Whether regulators and established social platforms will let OpenAI muscle into their territory remains to be seen, but the company is clearly done being just an infrastructure provider.
Before you experiment with Sora 2, you should probably learn how to use ChatGPT to its fullest potential. Check out the most comprehensive ChatGPT course you will ever take and more, right on Digestibly.

Create Character Animations with Wan 2.2 in Higgsfield AI
Higgsfield AI just made character animation accessible to anyone with a browser. In tandem with Qwen, the WAN 2.2 model lets you take any character image and make it perform actions from a template video—no animation skills required.
This is the kind of tool that turns a 3-day animation project into a 3-minute task. Perfect for content creators, marketers, or anyone who needs quick character animations without the traditional animation pipeline.
Here's how to use it:
Navigate to higgsfield.ai/animate in your browser.
Upload two files: your character image (the person or character you want to animate) and a template video (the movements you want your character to perform).
Select either "WAN 2.2 Replace" to swap a character in an existing video, or "WAN 2.2 Animate" to make your character perform the template's actions.
Hit generate and wait for the magic to happen. The model will process your inputs and generate the animated result.
The quality of your output depends heavily on your inputs—clear character images with good lighting and template videos with distinct movements work best.
Experiment with different combinations to find what works for your use case!
