AI video and media company known for Gen-series generative video models, now expanding into tools for ad creative and world models for robotics and medicine.
Nvidia and Sapphire Ventures joined Reactor's Series A, lifting the world-model startup's funding to $74 million from $59 million. Nvidia's stake sits in the layer that runs the models, days after AMD agreed to buy model maker World Labs for $8.2 billion in stock.

Runway debuted Praxis-1, an open-weight world action model it says adapts to new robot bodies with light fine-tuning, alongside an ad agent called Runway Ads. Because the weights are open, outside robotics teams can measure what that fine-tuning costs on their own machines.

Modal made multi-node GPU clusters generally available on October 1st, requested through one Python decorator and billed by the second. Dropping a reserved cluster for it means trusting a gang scheduler to place every node at once on one network.

Runway launched Runway Ads, an ad loop publishing to Meta, Google and TikTok that Runway says lifted the company's weekly output from 77 to about 900 ads. The results come only from Runway's own campaigns, and its learning step runs on data from platforms building rival automation.

Higgsfield AI spent $400,000 of Hell Grind's $500,000 budget on compute and $100,000 on the 15 people who made the 95-minute film. Its reported $5.4 billion valuation turns on how much of that compute spend it keeps from the model makers behind its platform.

Generating the interface as video instead of rendering it from code is a serious research bet. Runway's own preview still lists legible text and long-session coherence as open problems, which is roughly where ordinary interfaces begin.

Runway's WorldPrompt specifies a GWM Worlds 2 scene as a fixed first frame plus timestamped events, played out live at 24 frames per second. Authors get a timeline, but Runway's own researcher says how well the model follows it depends on the action.

CoreWeave's revenue backlog reached $66.8bn at the end of 2025, or 13.4 times the $5bn of revenue it booked for the year. The contracts are conditioned on delivery, and 2.25 GW of its contracted power is not yet live.

The agent returns layers, keyframes and timing that a designer can revise inside Adobe. Running it means paying for Higgsfield credits, a ChatGPT plan and After Effects at the same time. The runtime figures are Higgsfield's own.

The Los Angeles Times reports Google is offering hundreds of millions for studio libraries plus a slice of YouTube ad revenue, which tells Disney, Warner Bros. Discovery and Universal what their blessing is worth.

The five-second clip in three seconds is fal's own figure, measured on fal's hardware against an endpoint it does not control, and the throughput multiple only transfers if you know the batch size and GPU count behind it.

Universal, Sony and Warner all took equity in Stability AI's $76 million Series B. Two years after suing AI song generators, the majors are buying the toolmakers.

A prompt meant for 10 rows ran on 28,000. That is the buying question now: not price per seat, but what one mis-scoped action costs before anyone notices.

A one-afternoon test splits AI visibility in two: name recall lags funding and press by years, while category retrieval is already working for products the model cannot describe.

A DST Global-led Series B quadruples the company's valuation since January. The interesting part is what the money is for: compute contracts that decide who is still shipping at renewal.
