We’ve pushed an LTX-2.3 update today. The Distilled model has been retrained (now v1.1) with improvements to audio quality and a slightly refined visual aesthetic. It’s available on HuggingFace alongside the previous Distilled version. Along with the new checkpoint, we’ve also retrained the distilled LoRA, updated all four ComfyUI example workflows, and refreshed the union …
Language models (LMs), at their core, are text-in and text-out systems.
The open-weights model ecosystem shifted recently with the release of the
This paper was accepted at the Workshop on Navigating and Addressing Data Problems for Foundation Models at ICLR 2026. Large language models (LLMs) can struggle to memorize factual knowledge in their parameters, often leading to hallucinations and poor performance on knowledge-intensive tasks. In this paper, we formalize fact memorization from an information-theoretic perspective and study …

Building effective reward functions can help you customize Amazon Nova models to your specific needs, with AWS Lambda providing the scalable, cost-effective foundation. Lambda’s serverless architecture lets you focus on defining quality criteria while it handles the computational infrastructure. Amazon Nova offers multiple customization approaches, with Reinforcement fine-tuning (RFT) standing out for its ability to teach …
At Google Cloud, we often see customers asking themselves: “How can we manage our generative AI costs effectively without sacrificing the performance and availability our applications demand?” This is the million-dollar question — or, perhaps more accurately, the “tokens-per-minute” question. The key isn’t just about choosing the cheapest option, but about finding the right recipe …

Unitree is bringing its R1 to international markets. It arrives with some aerobatic capabilities and an entry-level price, but the question of what you’d actually do with it remains open.
In the pursuit of powerful and stable quantum computers, researchers at Chalmers University of Technology, Sweden, have developed the theory for an entirely new quantum system – based on the novel concept of ‘giant superatoms’. This breakthrough enables quantum information to be protected, controlled, and distributed in new ways and could be a key step …

In a world where artificial intelligence is quietly shaping who gets hired, who receives loans, and even how medical decisions are made, a new question is emerging: How does AI judge us? A new study by Prof. Yaniv Dover and Valeria Lerman from Hebrew University suggests the answer is both reassuring and deeply unsettling. The …

If you haven’t seen it yet, a model called see-through dropped last week. It takes a single static anime image and decomposes it into 23 separate layers ready for rigging and animation. It’s a huge deal for anyone who wants a rigged 2D character but doesn’t have hundreds of dollars lying around. The problem is …
