It is designed for interactivity between generative AI and the timeline, so you can inpaint anywhere on the timeline, extract frames and videos to use as references, use SAM2 for video masking and sam-audio for stem extraction etc. It comes with built-in workflows for …

Faster Rates for Federated Variational Inequalities

In this paper, we study federated optimization for solving stochastic variational inequalities (VIs), a problem that has attracted growing attention in recent years. Despite substantial progress, a significant gap remains between existing convergence rates and the state-of-the-art bounds known for federated convex optimization. In this work, we address this limitation by establishing a series of …

Grok 4.7 is now available on Amazon Bedrock

xAI’s Grok 4.7 is now available on Amazon Bedrock, adding a frontier model built for coding, long-running agents, and knowledge work to the Bedrock model catalog. It offers a 500K token context window and supports configurable reasoning effort at four levels: low, medium, high, and xhigh. Grok 4.7 is served on the bedrock-runtime endpoint through …

Why your startup needs open models alongside frontier APIs

Every week, I talk with founders who are building at an unbelievable pace. Teams are moving from inception to product-market fit faster than ever, with foundation models wired deeply into their core product workflows. Yet as startup architectures mature, a clear divide has emerged between teams struggling with margins and those scaling sustainably. The most …

I still can’t believe I can generate this all locally (Minimax H3)

Spent the whole day today trying to create this random transformation video. In total, I generated around 180 videos. A few initial images were generated with Krea2, and later all edits were done with the Qwen 2.1 edit model. All done using i2v with first / last frame technique. Everything was done in ComfyUI with …
