The next leap in AI video isn't just better visuals. It's having far more control over how those videos are created. Dreamina Seedance 2.5 is coming soon to the Dreamina platform, and what stands out isn't only the quality it's the workflow built around creators. Here's what's coming: • Multimodal input — combine up to 50 reference assets in a single generation. • Longer video generation — create continuous videos of up to 30 seconds. • Structured control — use white-model and green-screen references for more predictable results. • Multilingual creation — build content for international audiences with localization support. • Targeted refinement — edit specific parts of a video instead of regenerating the entire scene. These upgrades make Dreamina Seedance 2.5 feel less like another prompt-to-video model and more like a complete, controllable AI video production pipeline. Learn more: #dreamina #dreaminapartner #seedance #dreaminaseedance25

Most recent diffusion language model research (that I’ve seen) seems to be using masking as the noising process. It looks like, however, most closed-source models (Google Gemini Diffusion and possibly Inception Labs’ Mercury) use a different noising process, where instead of masking tokens, they replace them with different tokens (either with a random token or a semantically similar token). I wondered how they were getting such high throughput with the latter noising process, since I believed that optimizing inference with KVCache approximation would be more difficult (for various reasons). I visualized this noising process with tiny-diffusion and compared it to normal unmasking, and was very surprised to see how fast the generation “settles” into a reasonable output, and then only slightly refines afterwards, requiring much fewer steps in total. Unmasking (where tokens are never remasked, the typical implementation) is inherently limited in generation speed by the fact that an increase in tokens decoded per step leads to more errors due to the mismatch between individual and marginal token probability distributions we sample from. The token replacement noising process seems to have a much different set of characteristics. Because we sample each token per step, every token makes “progress” towards the final output each iteration (in addition to *potentially* giving other tokens more information in future steps). Generally, masking has outperformed other noising processes, which is probably why most research focused on it (using smaller models). But the paper referred to in the retweet shows that random replacement as a noising process may scale better as model size increases. Big labs might have noticed these results much earlier (due to having drastically more training resources and being able to test larger models), which may explain the discrepancy in the choice of noising process. I’m gonna test this with larger models, since tiny-diffusion only has 10M parameters.

Video diffusion models have strong implicit representations of 3D shape, material, and lighting, but controlling them with language is cumbersome, and control is critical for artists and animators. GenLit connects these implicit representations with a continuous 5D control signal describing the direction and intensity of a point light source. This enables single-image near-field relighting of an image using a video diffusion model. We use a ControlNet-like approach and show that, with a small amount of synthetic data, GenLit generalizes to complex real-world images. Given a single image and the 5D lighting signal, GenLit creates a video of a moving light source that is inside the scene. It moves around and behind scene objects, producing effects such as shading, cast shadows, secularities, and interreflections with a realism that is hard to obtain with traditional inverse rendering methods. GenLit shows that it is possible to get continuous control over implicit physical processes within a video model. I think this is just the beginning and promises to make such models much more practical for creators. Shrisha Bharadwaj will present today at SIGGRAPH Asia Room: S423/S424, Level 4 @ 13:50 on 15 of Dec.

This is some quietly impressive work on making video world models actually controllable in 4D space. VerseCrafter lets you take an input image, use something like Blender to animate the 3D camera path and object trajectories, then uses that to condition generation. Scribbling in 2D feels so crude in comparison. The authors represent everything in a shared 4D world state - static background as a point cloud, moving objects as 3D gaussian trajectories. The gaussians are an interesting choice because they capture position, shape, and orientation probabilistically rather than forcing rigid bounding boxes or category specific models like SMPL-X for human bodies. They bolt this onto frozen Wan2.1 with a lightweight adapter, so they get a strong video prior. They also built a pipeline to auto extract 4D annotations from real world videos to train this puppy. It doesn't look sexy yet, but IMO this is the interface video world models need - actual 3D authoring tools to exert control rather than crude scribbles and prompt incantations.

Wonderland: Navigating 3D Scenes from a Single Image Contributions: • First, we introduce a representation for controllable 3D generation by leveraging the generative priors from camera-guided video diffusion models. Unlike image models, video diffusion models are trained on extensive video datasets. This enables them to capture comprehensive spatial relationships within scenes across multiple views and embed a form of "3D awareness" in their latent space, which allows us to maintain 3D consistency in novel view synthesis. • Second, to achieve controllable novel view generation, we empower video models with precise control over specified camera motions. We introduce a novel dual-branch conditioning mechanism that effectively incorporates desired diverse camera trajectories into the video diffusion model. This enables expansion of a single image into a multi-view consistent capture of a 3D scene with precise pose control. • Third, to achieve efficient 3D reconstruction, we directly transform video latents into 3DGS. We propose a novel latent-based large reconstruction model (LaLRM) that lifts video latents to 3D in a feed-forward manner. With this design, during inference, our model directly predicts 3DGS from a single input image, effectively aligning the generation and reconstruction tasks—and bridging image space and 3D space—through the video latent space. Compared with reconstructing scenes from images, the video latent space offers a 256× spatial-temporal reduction while retaining essential and consistent 3D structural details. Such a high degree of compression is crucial, as it allows the LaLRM to handle a wider range of 3D scenes within the reconstruction framework, with the same memory constraints.

[LSTM] by Hand ✍️ LSTMs have been the most effective architecture to process long sequences of data, until our world was taken over by the Transformers. LSTMs belong to the broader family of recurrent neural network (RNNs) that process data sequentially in a recurrent manner. Transformers, on the other hand, abandon recurrence and use self-attention instead to process data concurrently in parallel. Recently, there is renewed interest in recurrence as people realized self-attention doesn’t scale to extremely long sequences, like hundreds of thousands of tokens. Mamba is a good example to bring back recurrence. All of a sudden, it is cool to study LSTMs. How do LSTMs work? [1] Given ↳ 🟨 Input sequence X1, X2, X3 (d = 3) ↳ 🟩 Hidden state h (d = 2) ↳ 🟦 Memory C (d = 2) ↳ Weight matrices Wf, Wc, Wi, Wo Process t = 1 [2] Initialize ↳ Randomly set the previous hidden state h0 to [1, 1] and memory cells C0 to [0.3, -0.5] [3] Linear Transform ↳ Multiply the four weight matrices with the concatenation of current input (X1) and the previous hidden state (h0). ↳ The results are feature values, each is a linear combination of the current input and hidden state. [4] Non-linear Transform ↳ Apply sigmoid σ to obtain gate values (between 0 and 1). • Forget gate (f1): [-4, -6] → [0, 0] • Input gate (i1): [6, 4] → [1, 1] • Output gate (o1): [4, -5] → [1, 0] ↳ Apply tanh to obtain candidate memory values (between -1 and 1) • Candidate memory (C’1): [1, -6] → [0.8, -1] [5] Update Memory ↳ Forget (C0 .* f1): Element-wise multiply the current memory with forget gate values. ↳ Input (C’1 .* o1): Element-wise multiply the “candidate” memory with input gate values. ↳ Update the memory to C1 by adding the two terms above: C0 .* f1 + C’1 .* o1 = C1 [6] Candiate Output ↳ Apply tanh to the new memory C1 to obtain candidate output o’1.

Yesterday at Brown University ICERM's workshop on “Agentic Scientific Computing and Scientific Machine Learning” I spoke about “Adaptive Swarms Across Scales”, making the case for scientific AI as systems that can create representations, stress them, fracture them, and enlarge the category in which future representations live. The category here is a composable and breakable working universe of science: data, hypotheses, simulations, measurements, tools, failures, figures, papers, provenance, and the transformations that connect them. Discovery happens when those transformations become executable, inspectable, composable, and capable of changing the world model they operate within. Atomistic modeling gives one category - states, forces, trajectories, observables, boundary conditions, conservation laws. Neural surrogates learn fast morphisms inside or between such categories. But discovery is higher-order: it changes which objects and morphisms are available in the first place: what variables exist, what operations are allowed, what evidence counts, what scale is active, what invariant is being preserved, and what kind of explanation the system is even capable of forming. This is scientific method as adaptive architecture: compression, stress, fracture, recomposition. Fracture matters here because it makes the logic physical: a non-commuting diagram realized in matter. The imposed load, material hierarchy, defect field, and assumed continuum description no longer map cleanly into the observed outcome. The crack is the obstruction and it identifies where the old morphism failed and where a new representation must be introduced. The physical crack and the categorical obstruction are the same event viewed in different substrates. ScienceClaw × Infinite is a machine for constructing and transforming a category of scientific artifacts. Each artifact is typed. Each operation has lineage. Each failed branch remains in the category as reusable structure. The “paper” is no longer the terminal object of science; it is one projection of a larger compositional trace, and it can be generated at any time for consumption by a human or an AI. With that the unit of scientific labor is changing. For most of the twentieth century the unit was the result (a measurement, a theorem, a synthesized molecule). It is now becoming the algorithm that produces results, and after that, the substrate of discovery itself. The static PDF is the wrong terminal object for this regime, and the role of the scientist with it. We now design algorithms that build algorithms, and eventually substrates in which such algorithms compose themselves. At that point, the scientist is no longer outside the discovery system. The scientist becomes one of the representations the system can transform. In that sense, the systems will eventually do science to us, and that is the structural consequence of the principle they are built on.

Trained on zero real-world data. Learned to walk, pick up boxes, and follow multi-step instructions... in the REAL world. ( 📌 Paper below) Researchers from Amazon FAR, Berkeley, Stanford, and CMU scanned real rooms with an iPhone, rebuilt them as 3D Gaussian Splatting scenes, then generated 48,000 synthetic trajectories of a Unitree G1 walking, grasping, and placing objects inside those virtual replicas. They rendered the robot's first-person camera view from each run and paired it with the matching language instruction and motion data. That's the dataset every humanoid team needs and nobody has: synced egocentric video + language + kinematics, at scale. Instead of collecting it in the real world, they manufactured it. They trained a vision-language-kinematics policy on that synthetic data alone, then deployed it on the physical G1 across five task types: navigation to a named object, lifting boxes of three different sizes with no per-size tuning, chained multi-step tasks, robustness to mid-task layout changes and flickering lights, and multi-minute long-horizon runs. No real-world fine-tuning at any point. Real-world interaction data has been the hard limit on humanoid learning... slow, expensive, and small. If scanning a room once and synthesizing thousands of labeled interactions holds up as a general recipe, that limit moves. Data stops being the bottleneck robotics teams have to solve for. 📌 Paper: Project: ——- Weekly robotics and AI insights. Subscribe free:

Agility Robotics and Boston Dynamics to Unitree: “Go back to China!” Leading US robotics companies have expressed support for the restrictions. Agility CEO Peggy Johnson issued a statement endorsing the GUARD Act, saying it “sends an important market signal as US robotics companies continue investing in resilient supply chains, domestic manufacturing capabilities, and trusted technologies.” In a recent interview with futurist Peter Diamandis, she said the Oregon-based robotics firm has been working with the Trump Administration. “We have an administration that’s very focused on the humanoid robots not going the way drones did,” she said. “We used to actually have a drone industry in the US and it’s largely gone offshore. They’re trying to prevent that same thing from happening to humanoids.” Earlier this year, Boston Dynamics sent its VP of software, Matthew Malcano, to Washington to testify before Congress about its biggest overseas rival. “Unitree is rapidly capturing market share in the US university, research, and law enforcement markets,” he said. “Researchers have reported crucial Unitree cybersecurity vulnerabilities. Unitree’s robots have also been seen in PLA military exercises and its ties to Chinese military have been noted by the House Select Committee on China as well as the Department of War.” Back in 2021, Unitree joined Boston Dynamics, Agility, ANYbotics and others in signing a pledge to not weaponize its autonomous machines. The company insists that its robots, including its new $650,000 rideable Mecha, are for civilian use only.

Agility CEO Peggy Johnson issued a statement endorsing the GUARD Act, saying it “sends an important market signal as US robotics companies continue investing in resilient supply chains, domestic manufacturing capabilities, and trusted technologies.” In a recent interview with futurist Peter Diamandis, she said the Oregon-based robotics firm has been working with the Trump Administration. “We have an administration that’s very focused on the humanoid robots not going the way drones did,” she said. “We used to actually have a drone industry in the US and it’s largely gone offshore. They’re trying to prevent that same thing from happening to humanoids.” Earlier this year, Boston Dynamics sent its VP of software, Matthew Malcano, to Washington to testify before Congress about its biggest overseas rival. “Unitree is rapidly capturing market share in the US university, research, and law enforcement markets,” he said. “Researchers have reported crucial Unitree cybersecurity vulnerabilities. Unitree’s robots have also been seen in PLA military exercises and its ties to Chinese military have been noted by the House Select Committee on China as well as the Department of War.” Back in 2021, Unitree joined Boston Dynamics, Agility, ANYbotics and others in signing a pledge to not weaponize its autonomous machines. The company insists that its robots, including its new $650,000 rideable Mecha, are for civilian use only.

as a former professional skater, I can say the technique here immediately reminds me of upper body positioning in speed skating. specifically the way the arms move across the body while the hips and torso rotate underneath them In skating that goofy motion helps manage the lateral shift of the center of mass and counter the angular momentum created by each leg it’s interesting is that the robot wasn’t explicitly taught to run this way the gait emerged through reinforcement learning as it searched for a faster, more stable and less thermally demanding way to move. yet it is not copying a speed skater It seems like two very different systems arrived at a similar solution to the same basic dynamics problem Convergent biomechanics ™ lol video is of an old competitor of mine who is currently crushing everyone in skating at the moment GUZMAN

Smart Remesh 2.1.7, on the way.... ** Cloth Remeshing ** coming soon.... Cloth Remesh · Progress 01: As I continue posting about cloth remeshing, I want to share some of the challenges I faced during development, as well as how I approached and solved them. This is Part 1. Remeshing clothing is more challenging than remeshing most other types of 3D models. Because clothing contains folds, wrinkles, and complex surface forms, it is very important to preserve as much detail as possible throughout the remeshing process. Standard methods that work well for organic models don't always give good results here, because they often require a much higher polygon count to preserve those details properly. To address this, I decided to use the garment's existing UV layout as part of the remeshing process. Each UV island is remeshed independently, and once the process is complete, all of the parts are combined back into a single mesh. This approach helps achieve better detail preservation with a lower polygon count, while also making the remeshing process faster and producing a more acceptable final result. #blender #b3d

One of the craziest use cases I’ve found for Jev: verifiers. I am so excited about this that I at least wanted to share the high-level idea. I used Jev to build a custom verifier for the /goal feature in my agent harness. It checks whether the goal is actually complete after every turn, making continuous verification cheap enough to scale. This means I can run more of these verifiers (previously handled by another expensive reasoning model) more frequently to keep the agents on track. System One models are perfect for verification. I think of this as scaling harnesses further by cleverly combining System One and System Two models. I have a feeling this will enable a new wave of scalable test-time compute methods. Watch this space closely. I've just started to experiment with this and am already seeing really good results. I need to explore and figure out a way to benchmark it. I will share more once I have more results. This is an insane unlock for long-horizon agents. You heard it here first. And you can expect to see more harnesses embracing this new pattern. Full guide dropping in the next couple of days.

BEAR SWIPE ENDED YEARS OF DEVELOPMENT IN SECONDS A grizzly weighs up to 300 kilograms and swings a paw with enough force to break a moose’s spine, so this clip doesn’t show the robot’s endurance, it shows the actual limit of what counts as field readiness. The humanoid runs on balance algorithms built for flat lab floors, wild grass and a sudden strike from a living animal are an entirely different class of problem. ▹ balance systems are optimized for predictable scenarios, not a chaotic hit ▹ the fall here isn’t a software glitch, it’s physical proof the actuators can’t react fast enough to force at that level ▹ companies test robots against people and objects on flat floors, almost nobody tests against actual wildlife, and this clip explains why Every new meter of demo-floor walking costs millions. One wild bear proved that for free in three seconds.

46 AXES. A FULL-BODY TOUCH SYSTEM. THIS HUMANOID IS BUILT TO FEEL CONTACT, NOT JUST COPY MOVEMENT! Watch the arms rise. The movement looks simple, but the interesting part is what sits behind it: a human-shaped machine designed around more than walking or waving. Vita Robotics says its bionic humanoid uses a 46-axis motion architecture, split into 23 axes in the body and 23 in the head, giving it a much wider range of movement than a basic display robot. The company also describes a full-body flexible tactile skin system, designed to detect touch and trigger physical responses. That changes the idea of what a humanoid is supposed to do: instead of only executing a programmed gesture, it is being built to react when a person interacts with it. And that is the bigger race in robotics. Making a machine move is one challenge; making it move naturally, respond to contact and behave consistently around people is another. 46 axes are not just a spec sheet. They are 46 ways for a machine to become more expressive, more responsive and harder to distinguish from a static prop.

Mel Gibson's physical depiction of evil in The Passion of the Christ mirrors an organism in a state of biological entropy, devoid of warmth and light. While likely an unconscious choice, Gibson’s stated goal is to represent evil as a distortion of good and order. Visually, the devil he portrays mimics the structural collapse of a biologically stressed organism. The devil's lack of eyebrows and hair is a manifestation of hypothyroidism. When the thyroid is underactive, overall energy production drops, forcing the body to forgo energy-intensive processes like hair growth and prioritize its remaining fuel for vital organs. The gaunt face reflects cortisol dominance. During periods of chronic stress, the body releases cortisol, which breaks down skin, muscle, bone, and connective tissues to provide emergency energy. This catabolic process dissolves structural proteins, leading to thinning skin and sagging, a sign of tissue wasting. Also, elevated cortisol levels forcibly redirect fat away from supportive areas like the face and deposit it in the abdomen. The devil’s pale, bloodless skin results from reduced peripheral blood flow. A hypothyroid body produces heat at a low rate, causing blood sugar levels to drop. To prevent hypothermia, the body secretes massive amounts of adrenaline, sometimes up to 30 to 40 times the normal amount (Peat, 1992). This adrenaline surge forcibly constricts blood vessels in the skin, conserving the little heat left around internal organs and leaving the skin cold and pale. The devil's androgyny is an expression of what happens to a developing organism under severe stress. A healthy, fully developed body relies on protective, differentiating hormones like progesterone and specific androgens to build structure, while a stressed organism relies on primitive emergency hormones like estrogen and cortisol (Peat, 2015). This stressed state halts proper cellular specialization and destroys the delicate hormonal ratios required for proper sexual dimorphism, pulling the organism toward an undifferentiated, amorphous, or "unisex" phenotype. The devil's behavior, especially during the manic state after Christ's resurrection, shows a reversion to the "lizard brain," or serpentine/snake-like behavior. In chronic stress, higher-order traits, such as love, creativity, empathy, cooperation, altruism, etc., are seen as expensive luxuries. When the brain lacks the ATP required to sustain these higher functions, it forcibly shuts them down to conserve fuel for basic survival. What remains is only the primitive brain stem, operating entirely on reactive survival instincts. In this low-energy, fat-oxidizing state, the devil, as shown here, becomes withdrawn, cold, angry, cancerous, and perceives the demands of the world, and the light of creation, as an active threat rather than an opportunity for expansion.

Destra Network| True decentralized Storage solution How Destra Decentralized File Storage solves the centralization issues in Filecoin & IPFS Filecoin and IPFS have become synonymous with decentralized file storage, highly hyped alternatives to traditional centralized data storage systems. However, a deep dive into their architecture reveals a crucially centralized component: both networks rely on a set of centralized bootstrap nodes. Whenever a new node wants to join the Filecoin or IPFS network, it must first communicate with these bootstrap nodes to obtain information about other peers, placing complete trust in the provided information. The Filecoin team operates these bootstrap nodes on centralized cloud servers. These nodes serve as the initial points of contact for new nodes entering the network, acting as directories to facilitate the network's mesh topology, and thus are critical components of the architecture. Major Centralization Concerns: 1. Surveillance: Centralized nodes offer a concentrated point for surveillance. Authorities or malicious actors could target these nodes to gather data on user activities, node interactions, and network dynamics, posing significant privacy risks. 2. Central Control and Censorship: The operators of bootstrap nodes potentially wield significant control over the network. They can influence which parts of the network are more discoverable or enforce certain network rules, leading to a form of gatekeeping. This centralized control contrasts with the decentralization ethos of blockchain and peer-to-peer technologies. 3. Single Points of Failure: Bootstrap nodes act as central hubs through which traffic and connections are often routed, especially during the initial connection phase. This setup can create single points of failure. If these nodes are compromised, go offline, or experience technical issues, new nodes may struggle to integrate into the network, potentially taking down the whole network. At Destra, we are building the Destra Decentralized File Storage to ensure that such centralization or pseudo-decentralization has no place in our architecture. As always, we are committed to our vision of 100% decentralization, delivering an unprecedented level of decentralization to our users and the broader ecosystem. As we continue developing the Destra Decentralized File Storage, we will keep on publishing regular updates to our community.

If you think OpenAI Sora is a creative toy like DALLE, ... think again. Sora is a data-driven physics engine. It is a simulation of many worlds, real or fantastical. The simulator learns intricate rendering, "intuitive" physics, long-horizon reasoning, and semantic grounding, all by some denoising and gradient maths. I won't be surprised if Sora is trained on lots of synthetic data using Unreal Engine 5. It has to be! Let's breakdown the following video. Prompt: "Photorealistic closeup video of two pirate ships battling each other as they sail inside a cup of coffee." - The simulator instantiates two exquisite 3D assets: pirate ships with different decorations. Sora has to solve text-to-3D implicitly in its latent space. - The 3D objects are consistently animated as they sail and avoid each other's paths. - Fluid dynamics of the coffee, even the foams that form around the ships. Fluid simulation is an entire sub-field of computer graphics, which traditionally requires very complex algorithms and equations. - Photorealism, almost like rendering with raytracing. - The simulator takes into account the small size of the cup compared to oceans, and applies tilt-shift photography to give a "minuscule" vibe. - The semantics of the scene does not exist in the real world, but the engine still implements the correct physical rules that we expect. Next up: add more modalities and conditioning, then we have a full data-driven UE that will replace all the hand-engineered graphics pipelines.
