Live now: Luma Variants.

Live now: Luma Variants. One approved ad. Every size. Every language. October 1, 2026 The hero is done. The real work starts. Luma has launched Variants. Now any Luma user can upload one approved static ad, pick formats and languages, and Variants builds every version for you. Your logo, headline, and CTA stay intact while the layout and copy adapt to each placement and market. Stop rebuilding by hand. Getting a campaign approved is one milestone. Shipping it everywhere is another. A single ad has to run as a Story, a feed post, a display unit, and a widescreen placement, often in several languages. Today, most teams rebuild each one by hand. That work adds up fast. Every manual rebuild is another chance for a clipped product shot, overflowing copy, a missing logo, or the wrong language going live. Built for teams that ship at scale. Ad Variants is for agency and brand teams who take one approved ad across placements and markets. * Multichannel rollout. Turn one campaign into placement-ready versions for social and display. * Global launches. Translate approved copy for every market while the visual system stays consistent. * The full matrix. Get 1:1 English, 1:1 Spanish, 9:16 English, and 9:16 Spanish from a single master, in one pass. Adapting Approved Ads shouldn't take an army. Here's how Luma Variants works: * Upload your master. Start with one approved static ad. * Pick your formats. Choose from five standard placements: Story 9:16, Portrait 4:5, Square 1:1, Medium Rectangle 6:5, and Widescreen 16:9. * Pick your languages. Select the markets you need. Ad Variants returns a version for every size and language combination. * Check the Preview. See each variant before you commit, and regenerate anything that isn't right. * Ship the Finals. Download them, or export straight to a Luma Canvas board for review with your team. Ad Variants is live today. Inside Luma, open the Discover tab and select the Ad Variants card to get started. This first release covers static ads, resizing, and translation. More is on the way.

AI-generated film Hell Grind cost $500K to make, sparking debate over Hollywood's creative future

AI video startup Higgsfield AI created the 95-minute film Hell Grind in under three weeks with a $500,000 budget, debuting it at Cannes this spring. The company raised $400 million in a Series B round in August at a $5.4 billion valuation, following an $80 million raise eight months earlier. Rival startup Runway raised $315 million in a Series E at a $5.3 billion valuation. The company partnered with Lionsgate and has evolved its technology from restyling existing videos to generating new content from text prompts. Luma secured $900 million in November 2025 from investors including Saudi AI company Humain, Nvidia, and AMD. McKinsey projects AI could influence up to 20% of original content spending on films and TV by 2030. SAG-AFTRA recently ratified a four-year contract with major studios establishing guardrails around AI usage in production.

Luma AI to launch fully Arabic interface for creative platform.

Luma AI to launch fully Arabic interface for creative platform. Arabic will become the first non-English interface available on Luma Agents later this year. Sep 05, 2026 Luma AI will launch a fully native Arabic-language interface for Luma Agents later this year, making Arabic the first non-English interface available on the company's unified AI creative platform. Announced at LEAP 2026 in Riyadh, the update will localise the full user experience, including navigation, menus and workflow tools, rather than limiting Arabic support to prompts or generated content. The rollout is aimed at creative professionals in Saudi Arabia and the wider MENA region, where fully Arabic interfaces remain relatively uncommon across AI generation platforms. Luma AI said the localisation process was shaped by feedback from Saudi creative communities over the past year. The company is positioning the update as a way to let Arabic-speaking users move from initial ideas through to finished creative work without switching between languages. The Arabic interface builds on Luma AI's partnership with HUMAIN and its wider expansion in Saudi Arabia, where the company has established its regional headquarters in Riyadh.

StationOne connects marketing's critical operations into a single, open, collaborative platform designed for creative excellence and team-wide productivity. Kochava, the real-time data solutions company for omnichannel outcomes, has announced the expansion of StationOne by Kochava with new, purpose-built workspaces for marketers and creative professionals, powered by top AI partners Higgsfield, Luma, and Spaceback by Rembrand. The announcement signals a new era of creative workflow: one where campaign assets are not just rapidly produced and adapted, but strategically optimised for every segment, every screen, and across every channel - unlocking new value for creative teams and marketers alike. The New Creative Imperative: Speed, Fidelity, and Human Focus Modern campaigns demand unmatched speed, personalisation, and creative excellence - yet creative leads and teams are still too often burdened with busy work, manual resizing, and repetitive adaptation for dozens of formats and audiences. With StationOne's new workspaces, all that changes. By seamlessly integrating industry-defining creative tools from Higgsfield, Luma, and Spaceback by Rembrand, StationOne synthesises model-driven creative iteration directly into the workflows of activation and optimisation. "Our vision for StationOne is simple: unlock creative possibilities, eliminate repetitive barriers, and amplify what human teams do uniquely well," said Charles Manning, CEO at Kochava. "With these workspaces, AI doesn't replace creativity - it embeds it into accelerated ad operations workflows natively." Higgsfield: Unmatched Customisation, Effortless Asset Creation Higgsfield pushes creative boundaries further with AI-driven video and image generation built for marketers seeking distinctive, hyper-customised content. With direct integration into StationOne, creative leaders can harness Higgsfield to produce, test, and refine dynamic creative assets at scale, making true content personalisation not just viable, but effortless. "Higgsfield exists to turn every brand's vision into personalised creative at the speed and quality modern campaigns demand. Together with StationOne, we're giving creative teams a faster path from idea to finished work, with each asset built for the audience it needs to reach," said Taz Patel, Vice President of Platform Partnerships at Higgsfield. Luma: Fastest Path from Idea to Impact Luma is renowned among creative pioneers for delivering game-changing speed, model-level brand intelligence, and absolute creative control. Teams can explore ten creative directions before the morning standup and deliver fifty on-brand variants by end of day. By bringing creative generation and workflow orchestration closer together, Luma and StationOne enable teams to spend less time managing processes and more time focused on strategy, storytelling, and creative development. "Creative teams are under growing pressure to produce more content, adapt campaigns faster, and maintain brand consistency across channels. By bringing Luma's generative AI capabilities into StationOne, we're helping creatives move from concept to execution more efficiently while giving greater control over the final outcome," said Caroline Ingeborn, COO, Luma Spaceback by Rembrand: Social Creative Intelligence, Built for the AI Age Spaceback's AI-native Social Creative Intelligence platform helps marketers identify what resonates with audiences, uncover competitive opportunities, and turn those insights into high-performing creative. Through its integration with StationOne, brands can generate, activate, and measure multiple creative variants across programmatic and CTV, bringing the impact of social beyond walled gardens and from insight to activation in the same day. "Generative AI makes creativity limitless, but social shows marketers what's worth making," said David Wiener, Chief Product Officer at Rembrand. "StationOne and Spaceback turn those signals into creative that can be generated, activated, and measured across programmatic and CTV, helping marketers move from insight to outcomes faster." StationOne: The Creative Orchestration Layer Marketers Demand More than a toolkit, StationOne connects marketing's critical operations - creative, analytics, attribution, and more - into a single, open, collaborative platform designed for creative excellence and team-wide productivity.
