OpenAI Researchers Train Weight Sparse Transformers to Expose Interpretable Circuits
OpenAI’s new work on ‘sparse circuits’ trains GPT-2 style language models so that almost all weights are zero, which forces behaviors like quote matching and variable type tracking to run through tiny, explicit circuits, these circuits are both necessary and sufficient for the task, up to 16 times smaller than in dense baselines, and can be pruned, visualized, and stress tested, giving mechanistic interpretability a concrete path toward scalable safety tooling for future models.

MBZUAI Researchers Introduce PAN: A General World Model For Interactable Long Horizon Simulation
MBZUAI researchers introduced PAN, a general world model that turns text conditioned video generation into interactive long horizon simulation. PAN implements a Generative Latent Prediction stack that combines a Qwen2.5 VL 7B based latent dynamics backbone with a Wan2.1 T2V 14B diffusion decoder using Causal Swin DPM for stable sliding window rollouts. Trained on large scale action centric video data, PAN achieves 70.3 percent agent simulation fidelity, 53.6 percent transition smoothness, and 64.1 percent simulation consistency, and significantly boosts simulative planning performance over VLM only agents.

Germany based open-source remote access company - NetBird just built an "AI Mega Mesh". A project that started out to prove that multi-cloud networking doesn’t have to be complicated, resulted in creating a secure AI inference infrastructure that connects GPU resources across multiple cloud providers using Microk8s, vLLM, and NetBird.

How Powerful are Diffusion LLMs? Rethinking Generation with Any-Process Masked Diffusion Models
Any-Process MDM (AP-MDM) reframes Diffusion LLMs as full algorithms, not just faster decoders. Building on Masked Diffusion Models that already match PRAM parallel time, the paper shows that adding remask, insert and delete operations pushes expressivity from P to PSPACE under polynomial context, while staying close to standard encoder only Transformers. Empirically, AP-MDM delivers strong gains on Sudoku, Dyck languages, graph editing and parity, highlighting edit based generation as a serious frontier LLM direction.
