Beating AI News reports, citing The Information and sources familiar with the matter, that DreamWorks co-founder Jeffrey Katzenberg is launching an AI video company with former OpenAI Sora lead Bill Peebles and ex-Dropbox CFO Sujay Jaswa. The startup will train its own video models to target filmmakers directly, and is currently in talks with investors including a16z for funding. The company’s name and funding size have not been disclosed. Peebles served as Sora’s core technical lead and is one of the authors of the Diffusion Transformer (DiT) paper. He left OpenAI shortly after the company shut down Sora’s consumer app and API this year, publicly stating at the time that exploratory research of this type needs space to operate outside a company’s core product roadmap. Katzenberg has already made an AI video bet this year: in May, his firm WndrCo participated in a $59 million funding round for real-time AI video startup Reactor. This time, he is going beyond investor status to co-found a company with the former Sora lead to build its own models. This marks Katzenberg’s most ambitious video venture since Quibi. The short-form video platform raised $1.75 billion but folded shortly after launching in 2020. Six years later, he is returning to the video space, though this time shifting from a short-form platform to developing AI models for filmmakers.

Beating AI Express News (Dongcha): DeepSeek’s V4.1 Flash is now rolling out on its app, merging its original three modes—“Fast”, “Expert”, and “Image Recognition”—into a single entry point.

DeepSeek previously noted that the new model has fully outperformed V4 Pro across metrics including performance, cost, speed, and total processing time, and will take over all V4 Pro requests ahead of the launch of V4.1 Pro.

Since the start of this week, the on-chain rally driven by the Robinhood chain has temporarily cooled off, with major cryptocurrencies seeing broad pullbacks. As a result, the market is pinning hopes for the next rally on Arc Chain, set to launch on September 16. Arc is an open blockchain network developed by stablecoin issuer Circle, primarily targeted at institutional users. There is significant divergence in the market over whether Arc will strongly support crypto-native meme coin culture. However, multiple crypto-native platforms have already announced they will support Arc Chain immediately upon launch, including NFT marketplace OpenSea and meme coin platform FOMO. In response to FOMO’s launch announcement, Circle co-founder Jeremy Allaire also gave an immediate positive response, which is seen as a potential sign of support for the crypto-native community. Whether Arc can successfully carry on the on-chain rally after its launch remains to be verified by the market.
