<strong>DeepSeek Builds for Huawei Ascend (6 minute read)</strong>
</span>

<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
DeepSeek plans to start rebuilding the software ecosystem around Nvidia's hardware so that Chinese chips become genuinely easier to use and capable of training frontier AI models. Nvidia's CUDA ecosystem provides developers with a mature set of tools for writing programs, optimizing performance, and getting thousands of GPUs to work together efficiently. DeepSeek is trying to create a layer of abstraction between models and the underlying GPU hardware that could potentially sit on top of either Nvidia GPUs or Huawei Ascend chips. If all goes well, the cost and difficulty of moving AI workloads from Nvidia to Chinese AI hardware could fall significantly.

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
NVIDIA's OpenShell provides a policy-controlled runtime for autonomous agents, enforcing file, system-call, network, and credential access at the kernel level. It also uses formal verification to identify risky permissions before policy changes are applied.

<strong>Generalization Dynamics of LM Pre-training (4 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
During pre-training, models can abruptly switch response patterns, a phenomenon termed MODE-HOPPING. Tests reveal this behavior in OLMo3-32B during arithmetic tasks, showing sudden shifts between pattern-following and correct task inference as training progresses. Controlled experiments suggest competing shallow and generalizable circuits within models, revealing that longer training doesn't always guarantee better generalization.

<strong>A new transformer passes its hidden state to the next token instead of recomputing it (25 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Researchers built LIFT, a transformer that feeds its internal state back into the next generation step instead of squeezing everything through the single token it outputs. Training stays parallel because the states come precomputed from an off-the-shelf model's next-token predictions, while at inference the model feeds back its own. LIFT models from 135M to 1B parameters beat token-matched standard transformers on language modeling, reasoning, and procedural tasks, so the next question is whether the gains hold at frontier scale.

Factory has fired VC Chris Degnan from his role as a board advisor due to allegations that Degnan shared confidential information with Cognition, Factory's biggest competitor. Degnan joined Cognition as its chief revenue officer two hours after the announcement. He refutes that he was fired and said that he resigned when he told Factory's CEO he was taking the job. There could be consequences for perceived board-level conflicts of interest.
