I built and trained a ~6M parameter GPT-2 entirely from scratch in C++, and it actually generates English text with mostly correct grammar! No PyTorch and no external dependencies. Just pure C++ 20. More info, GitHub link, and screenshots below!

We’re building out our embedded engineering team to develop the next generation of data collection hardware for robotics. Multiple roles- all based in Delhi NCR. 25-30 LPA CTC. If you can debug something you cannot see, please apply. Link in comments. Rt for good karma 🙏

@ClementDelangue @atreides_sf Let's be real, all closed models profit from open models WITHOUT GIVING BACK.

Been experimenting with procedural locomotion on #GaussianSplat environments from @theworldlabs . Built a little multi-legged robot in Unity that raycasts against the splat data to figure out where to place its feet, no meshes or colliders involved... Pretty fun to climb surfaces, walk on walls, and set a weird number of legs on the fly :) Still rough around the edges but pretty fun to watch it figure things out. #GaussianSplatting #Unity3D #WorldLabs #ProceduralAnimation

Today, we publicly released RoboCasa365, a large-scale simulation benchmark for training and systematically evaluating generalist robot models. Built upon our original RoboCasa framework, it offers: • 2,500 realistic kitchen environments; • 365 everyday tasks (basic skills + long-horizon mobile manipulation); • Over 3,200 objects with many articulated fixtures/appliances. All are designed for fully controlled, reproducible benchmarking of robotic policies. Progress in robotic foundation models is real. But it’s still hard to answer basic questions like: How close are we to general-purpose autonomy? What factors drive generalization? What are the model/data scaling curves like? Real-world eval is slow and noisy, and existing sims (like LIBERO, which we built 3 years ago) often lack sufficient task and scene diversity. This benchmark comes with 2,200+ hours of demonstrations and 500K+ trajectories to support studies of multi-task training, pretraining, and continual learning at scale. Check it out at robocasa.ai

Say you have trained your deep learning model. It works. But do you know what it has actually learned? 🚀 We’ve built SymTorch: a library that translates deep learning models into human-readable equations. I've attached here a quick video demonstrating how SymTorch works.

SHOCKING ‼️ Delhi | A patient from Madhya Pradesh died within 24 hours of admission at BLK Max Hospital. After ₹2 lakh was paid, the family alleged an additional ₹1 lakh demand and claimed the hospital withheld the body. NHRC member Priyank Kanoongo had to intervene. It is Shamefull that he along with Officials and Police had to reach the Hospital to secure the handover after much warnings.

Just a few months after releasing Scoot, which we feel redefined motion generation quality, our team has made substantial improvements in speed, quality, subtlety, and instruction following. This comes in concert with our newly scaled data collection and labeling efforts, compute increase, substantial architectural improvements, and more stable / scalable training dynamics. Swing is our new flagship movement model. It's live today in Cartwheel studio with infinite batch generation coming soon to our API. Treating Movement as a fundamentally new data type has really unlocked our ability to rapidly make improvements. As it turns out there are far more use cases than you might imagine from entertainment to robotics.

so I started with FreeCAD, since i am a linux guy, haven't touched windows since the past 8 years. Also I did this online course from Uni of California Irvine on "building your hardware for your embedded and IoT projects" which had FreeCAD as the main CAD software. FreeCAD was free, and fun, yeah a bit buggy sometimes but gets the job done, since initially all the CAD work i had was just builidng cases, or mounts, or some light hobby stuff. So FreeCAD did just fine. Then I joined a company as a product engineer where I worked with LiFePo4 home energy storage battery packs and was responsible for all the modules of the pack (Cells, BMS, MCUs, Touch Display ) mainly the embedded system. Since I was the product engineer, I'd have back and forth convos with the CAD designers off the battery pack box/casing. I didn't really do any CAD work on that project, tho it seemed really interesting to me. They used Solidworks, and I installed windows for it(swallowing that was difficult); to do Solidworks in my free time which I hardly got. I tried Solidworks and I kinda liked it. But then I quit the job and started working on my SAAS products. A few months into it, it's not fun anymore, slowly getting started with CAD and eventually to electronics to hardware products. Now, I want to go about CAD. I'll be doing a 30 days CAD challenge increasing in complexity and will be sharing daily progress here! It was day 2; I designer a bolt and a nut. I'm going with Fusion 360 for now, coz i like the UI/UX and the hobbyist version is free. So yeah. This is so much fun, i completely lost track of time while doing it. Gemini on the side is alot helpful.

We have a new open source video model. These clips were all generated with LTX-2 on the creator's local machine 🤯 It can make clips up to 20 seconds at 4K resolution. And it speaks! (created by u/yanokusnir)

learn CAD. seriously. not as a “nice to have”. as a thinking tool. start with fusion 360 (hobbyist). it’s free. it’s powerful. it’s enough. cad teaches you how reality works: • constraints over vibes • tolerances over guesses • assemblies over parts • manufacturability over aesthetics you stop imagining objects. you start reasoning about them. every good hardware engineer thinks in sketches, features, and parametric relationships. change one dimension. the whole system updates. that’s systems thinking in physical form. once you can model: you can 3d print. you can cnc. you can design enclosures, brackets, mechanisms. you can actually build. software people write abstractions. cad people design reality. learn CAD early. it compounds fast.

Taking parental leave for some deeply needed reading and it's fascinating to see the walls between SFT and RL crumbling. We’re moving toward a unified paradigm where supervised learning adopts RL ideas for a better conditioned pipeline. Thrilled to see this space growing e.g. via PPO style clipping (Proximal SFT - Zhu et al), direct KL reg (Anchored SFT - Li et al). importance sampling (Direct Fine-Tuning - Wu et al). Our own work took this to the extreme by fully replacing the SFT stage with (inverse) RL arxiv.org/abs/2409.01369 It’s still an open question where on this spectrum we will eventually converge, but my estimate is we’ll land much closer to full RL across the entire pipeline.

@WatakoLab I would like to know whether STL files are available or not for this robot for educational purpose

二足歩行は色々と心折れたので、倒立振子型で作成してみようかと検討中…。 ホッパー君の知見を活かしつつ、上半身の自由度が上がるので、色々と面白そうかなぁ、と。

@YuXiang_IRVL I’ve tried many of the imx219 variant cameras. Highly recommend this dual imx219 stereo camera by @waveshare00 The device tree overlay for the camera is already included as a default for the jetson.io gpio configuration and it works nearly out of the box. You may need a mediamtx config for low latency camera streams which are in my open source repo. Happy to send you a free field kit that includes a mount for the dual imx219 camera github.com/implyinfer/jet… waveshare.com/imx219-83-ster…
