The paper I've spent most of my PhD working on is now published in The Lancet Digital Health. A selfie can be a biomarker. Our faces reflect many things about our health, from aging and lifestyle to disease. In our new study, we developed FAHR-Face, a foundation model trained on more than 40 million face photos. We used it to build two models that estimate biological age and mortality risk in cancer patients from a single selfie. One of the most interesting findings is that the two models capture different information. They focus on different facial features and provide complementary information about health. Doctors have always used appearance as part of their clinical judgment. With AI, we can start to measure some of these signals objectively. I believe face photos could become one of the most accessible biomarkers of health. But there is still a lot of work ahead before these models can be used in clinical care. Paper and our ongoing FaceAge research study in the first reply. Huge thanks to the team and my supervisors. cc @dbittermanmd @BenjaminKannMD @HugoAerts @Dr_RayMak

Just added leaderboards to PongPong 🏆 Spent all this time building the game, so I’d better be good at it 😂 Do you think you can beat my longest shot?

App Store calling a 3D world builder spam is wild That custom first time walkthrough is a solid workaround Hope review lands soon
Having a hard time getting this interior design / world builder 3D app approved by the App Store review for Vision Pro. It’s getting rejected as spam..? So I created this custom first time 3d walk through experience. Hope this helps.

@hunter_spatial solved realistic asset generation for Apple Vision Pro, worth a try!
I created the most photorealistic scene generation pipeline available for native RealityKit Apple Vision Pro apps. I could keep it to myself, but I’m giving it away for free. RealityHD v5.0 is now available, with optimizations to be more token-efficient while generating ultra-realistic scenes. It also includes our latest medical related props and scenes, as seen in this video. I hope this enables the next generation of visionOS developers to build realistic simulations.

Jev could change how we build AI agents. I reverse engineered the idea and built Mini Jev from scratch. Trained on 50K agentic logs. Fully working. Open source on Hugging Face. Now I am gathering a team to push it toward production. huggingface.co/samatv256/min…

do not use @whop to accept payments it’s a vibecoded payment system by dumb ass engineers avoid losing your hard earned money just stick to stripe or a good MOR that handles fraud otherwise you are so done like me yesterday really fucked up situation

I’ve been researching depth-residual routing & delta memory- Kimi K3 proved this holds at 2.8T params. But only for models trained this way I then asked: can you retrofit this onto existing LLM/world models? Introducing Retro-DARC: a Delta Attention Residual Compute adapter  that retrofits depth-selective memory onto existing models without retraining: EA exact no-op at insertion (bitwise 0.0 deviation on 3 public checkpoints - proven exact even through MoE routing and early exit), adapter-only training, exact rollback, and content-level memory audits that weight-touching adapters can't express by construction. The early results are promising. A ~262K-param adapter beat LoRA on a frozen public checkpoint, inserted at zero behavioral risk. And it's the first memory you can audit: zero the bank and the frozen loss returns to machine precision; shuffle it and 70–107% of the gain vanishes. That's a model measurably using its own computation history. Retro-DARC is useful for improving K3 too. K3 serves in MXFP4/MXFP8, and layer outputs - exactly what its AttnRes retrieves - collapse under that corruption in my tests (0.04–0.75 top-1) while normalized delta keys hold 0.86–0.99. A Softmax1 null route with proven mass bounds lets the router decline to retrieve instead of forcing the sinks and outliers OASIS documented; typed memory turns "what is depth retrieval doing?" into a runnable audit. And one experiment is free: K3 already computes a per-step KDA update magnitude and throws it away - that's a depth-saliency prior waiting to be read. For world models, the same contract becomes one typed memory interface: Retro-DARC-X gives world/action planners a single bank - observations, actions, tools, latent causes, traces, physics residuals, failures - the substrates a planner needs to remember in order to act over long horizons in the physical world. You can experience the thesis yourself. I created lucidre.am/memory which runs the paper's memory contract inside a walkable AI world. Innovation Memory makes your interactions survive looking away or reloading, and Dream Residue turns your movement into an inspectable glowing trace. Join the main Lucidre.am co-creation exhibition - the contest opens Wednesday. One of the six memory applications of the paper - saliency-weighted curation, will rank worlds by genuine novelty rather than recency and pick each world's most surprising viewpoint. And we're bringing live shows to SF + LA next month: screens showcasing worlds that remember, so you can literally play hide-and-seek with a dream that knows where you hide. Hide-and-seek is the exact test every 2026 world-model benchmark says the field fails, something leaves the frame, keeps changing, and has to come back right. This has been a fun little one-person research project so far! I’d love feedback and keep working on it. I’ve had over 100 references- thanks for all the prior work from teams that inspired me! I'd also love to intern at a GPU-rich lab (lol) and keep making beautiful worlds - if you let me keep running my remaining tests :) 2MB adapter kit, demo, prior iterations:adacyb0rg.github.io/retro-da… Paper: adacyb0rg.github.io/retro-da…

It's exciting to see developers continue pushing the limits of visionOS. Updates like this show how spatial apps are becoming more capable, more immersive, and more practical for everyday use.

AI is changing game development faster than most people realize. Seeing a playable Apple Vision Pro game come together in such a short time shows how quickly ideas can move from imagination to reality. The barrier to building keeps getting lower.
