    Great work led by Jiale! NoRA builds on LoRA’s parameterization, with the down-projection matrix normalized. Even more surprisingly, applying this normalization only at initialization is already sufficient to obtain considerable performance gains. More details in

    1/ How can we make Low-Rank Matrices behave more like Full-Rank Matrices—and achieve higher rank efficiency? We release our new paper: NoRA: Normalized Low-Rank Adaptation. Paper: arxiv.org/abs/2608.31036

    Our recent works, DiagDistill (ICLR’26) and XYZFlow (ICML’26), are built on a simple principle of progressively strengthening constraints. Less trajectory ambiguity → fewer-step generation. The key is to spend more compute early, when generation is uncertain. As context

    Great work! Glad to see spectrum preservation serves as a central principle for improving RLVR. We also have proposed a new optimizer called Pion (spherelab.ai/pion/) that is designed with spectrum preservation as the first principle. Pion not only work well for RLVR, but

    People keep asking me: what's different about optimization in RL? Seemingly nothing — the pre-training stack just works (Adam, even SGD 👀 @saagnikkk). Bringing some answers from my last work (sorry for the delay — been cooking 🚀). We introduce ISO: Isospectral Optimization:

    Today, we are introducing Inkling. Inkling reasons efficiently across text, image, and audio modalities. We are making the full weights available. thinkingmachines.ai/news/introduci… Available today for fine-tuning on Tinker. Play with it in the Inkling Playground. 🧵

    Excited to share SymbOmni, our ECCV’26 work on a self-evolving agentic system for complex image and video generation/editing. SymbOmni learns new symbolic concepts by composing existing skills. Its self-evolution is driven by verbalized backpropagation, where successful past
