Full title: LeWorldModel: Stable End-to-End Joint-Embedding Predictive Architecture from Pixels

https://github.com/lucas-maes/le-wm

Abstract: Abstract: Joint Embedding Predictive Architectures (JEPAs) offer a compelling framework for learning world models in compact latent spaces, yet existing methods remain fragile, relying on complex multi-term losses, exponential moving averages, pretrained encoders, or auxiliary supervision to avoid representation collapse. In this work, we introduce LeWorldModel (LeWM), the first JEPA that trains stably end-to-end from raw pixels using only two loss terms: a next-embedding prediction loss and a regularizer enforcing Gaussian-distributed latent embeddings. This reduces tunable loss hyperparameters from six to one compared to the only existing end-to-end alternative. With ~15M parameters trainable on a single GPU in a few hours, LeWM plans up to 48× faster than foundation-model-based world models while remaining competitive across diverse 2D and 3D control tasks. Beyond control, we show that LeWM's latent space encodes meaningful physical structure through probing of physical quantities. Surprise evaluation confirms that the model reliably detects physically implausible events.

Thanks for the paper link, very different figures from the random USA newspaper article :)

I'd love to see an age adjusted figure as well as it's likely Europe has likely more very old people and my guess is that heat/cold mortality is concentrated in the very old people.

guerby — Fri, 26 Dec 2025 15:25:22 +0000

I bought a Gen11 framework 13 then later when available I replaced its motherboard by a Gen12.

The old motherboard with the coolermaster case is tucked between two books in my library and is now running my home proxmox.

64GB RAM 4TB NVME 4C/8T 2.5G ethernet and ... 2 Watt idle.

I did run "proxmox in proxmox" with ceph and cloudinit/live migration for a conference I gave on this old motherboard:

I bought several "Security Key NFC by Yubico": their cheapest model, no storage or fancy stuff.

My personal strategy is to use keys generated this way:

ssh-keygen -t ed25519-sk

Rules:

- A generated key never leave the machine it was generated on.

- ssh agent is never used

- ProxyJump in HOME/.ssh/config or -J to have convenient access to all my servers.

- DynamicForward and firefox with foxyproxy extension to access various things in the remote network from my local machine (IPMI, internal services, IoT, ...)

- On the web no passkey, only simple 2FA webauthn.

My understanding is that more features including "storage" means more attack surface so by avoiding it you're 1/ more secure 2/ it's cheaper.

White paper on passkey says their security is equal to the security of the OS (Microsoft Windows ...) so I avoid passkeys.
