LingBot-Video: sparse-MoE video diffusion transformer (13B total, 1.4B active) post-trained as an action-conditioned world model[R](reddit.com)
Single-stream diffusion transformer with a DeepSeek-V3-style sparse MoE (128 experts, top-8 routing, 1.4B active of 13B total). Six-reward RL post-training including a physical-plausibility reward, plus an action-to-video mode that predicts robot rollouts from action and hand-pose conditions. Weights, code, and a Diffusers/SGLang stack are open under the LingBot-Video name. Two things I would push on, and would genuinely like this sub's read: The physical-plausibility reward is graded by a VLM from sampled frames. Is a VLM a defensible judge of physics, or is that Goodhart waiting to happen? (They do add real-video negatives to fight reward hacking.) It is framed as a policy evaluator and action planner, but every result is video-frame quality with no closed-loop robot numbers. Where is the line between a video generator and a world model? On RBench it posts the top average, though the reasoning-heavy dimensions still go to a closed model, and it is only second on general T2V in their own eval. Please tear it apart.

I studied 150+ Robot Learning papers, and every single one is inside: The End-to-End Robot Learning Pipeline: The Technical Breakdown.(reddit.com)
From data collection to sim-to-real deployment, I put together an 8-part breakdown covering the entire robot learning stack. It goes through teleoperation hardware, generative models for action generation, VLAs, world models, RL fine-tuning, and real-world evaluation, all grounded in the actual papers.

Bitcoin under pressure as Trump says Iran ceasefire is over(reddit.com)
Bitcoin is facing renewed pressure after comments from Trump suggesting the Iran ceasefire is effectively over. Rising geopolitical tensions have pushed oil prices higher and increased uncertainty across global markets. Do you think this is a short-term reaction, or could geopolitical risks have a bigger impact on Bitcoin and other crypto assets in the coming weeks? submitted by /u/Webclues_Infotech [link] [Kommentare]
