CapCut, Tencent and Kuaishou race to build AI tools for interactive film games.

CapCut, Tencent and Kuaishou race to build AI tools for interactive film games. Published: October 11, 2026 Want to read in a language you're more familiar with? ByteDance's CapCut team, Tencent and Kuaishou are all rolling out AI tools for branching, playable stories. Costs are falling, but scripts, hit titles and distribution remain open problems. Several of China's biggest internet companies are building AI tools for interactive film games, a genre of branching, playable video stories, in a bid to own the creator entry point for what could become a mass-produced content format, according to a Chinese media report published on October 11. On September 20, ByteDance's video editor CapCut, in its China edition, unveiled ICG Studio, an AI interactive film game creation platform now in closed beta. Creators start from a story outline, then generate a script, persistent character, scene and prop assets, and storyboards. By chatting with an agent, they can branch the plot at any decision point and generate new storyboard shots, so characters and sets can be reused across storylines. Tencent has four products across different teams. TDream, billed as AI engines for playable cinematic worlds, turns scripts into video and adds branching choices. LightSpeed Studios launched a creation platform in May that breaks interactive story production into six standardized steps for non-professional users. Project Craft, an AI game creation platform shown at Tencent's SPARK 2026 event, generates 2D and 3D game prototypes from text. DreamNow is a showcase and discovery platform for AI videos, images and interactive titles. Kuaishou said in July that AI interactive content creation features were coming. Hits such as The Invisible Guardian and Love Is All Around showed there is an audience for the genre, but high production costs have kept the supply of quality titles thin. Developers interviewed say AI is already cutting costs. One game producer said character art that used to cost RMB 2,000 per image now costs about RMB 800 with AI assistance, and a RMB 200,000 small-game budget can fall to around RMB 150,000. Problems remain. Interactive scripts are far longer than short-drama scripts, and AI still cannot write them well. A hoped-for data flywheel, in which every player choice trains better plots, is unproven because the reasons behind a click are hard to attribute. The genre also lacks a dedicated distribution channel; most titles still sell as standalone games on platforms such as Steam, and whether AI-made titles will need a game publishing license is unclear. For now, the near-term opportunity looks strongest in tools for professional creators, which helps explain why the platforms are racing to offer them.

Arizona sues TikTok, alleging app was engineered to get kids addicted and hide the harms.

Arizona sues TikTok, alleging app was engineered to get kids addicted and hide the harms. A state is suing one of the world's biggest social media apps over allegations that it was built to get children and teens addicted while hiding the toll on their mental health. The lawsuit accuses TikTok and parent company ByteDance of using infinite scrolling, auto-play, push notifications and appearance-altering filters to keep minors on the app so the company can profit from their data, says Arizona Attorney General Kris Mayes. "TikTok touts its supposed safety measures to convince parents that this product is safe for young people. But behind the company's marketing is a platform engineered to exploit the vulnerabilities of developing brains, pushing Arizona kids toward compulsive use, harmful content, and dangerous behaviors while failing to protect them from adults who use the social media platform to groom or solicit minors. It's unconscionable." The complaint alleges TikTok downplayed or failed to disclose risks including depression, anxiety, disordered eating and self-harm. It also alleges the company knowingly allows children under 13 on the app despite publicly claiming to bar them. "The complaint further alleges that TikTok's recommendation algorithms expose minors to increasingly extreme, harmful, or age?inappropriate content and that TikTok's content?moderation practices are inadequate to block much of the dangerous material on the platform." The state alleges TikTok's 60-minute screen time limit for teens was known not to cut their use. A TikTok spokesperson denies the allegations, reports KJZZ. Says the spokesperson, "This lawsuit relies on misleading and inaccurate claims and deliberately ignores the concrete safety measures TikTok has voluntarily implemented to support the well-being of our community. We will vigorously defend against these claims."

ByteDance's Doubao app lands on Huawei HarmonyOS PCs with Doubao-Seed-2.1 Pro and Turbo.

ByteDance's Doubao app lands on Huawei HarmonyOS PCs with Doubao-Seed-2.1 Pro and Turbo. Published: October 7, 2026 Want to read in a language you're more familiar with? Doubao's native HarmonyOS PC app ships with Doubao-Seed-2.1 Pro and Turbo, chat and work modes and agent-style tools; Huawei says it topped the HarmonyOS PC wishlist. ByteDance's AI assistant Doubao is now available as a native app on Huawei's HarmonyOS PCs. Chinese tech outlets first reported the desktop client's arrival on October 1, and IT Home confirmed on October 7 that users can download it directly by searching for Doubao in the HarmonyOS app store. Huawei said Doubao ranked first on the HarmonyOS PC user wishlist, the list of apps owners of its HarmonyOS computers most want to see on the platform. The first version ships with two models, Doubao-Seed-2.1 Pro and Doubao-Seed-2.1 Turbo. ByteDance released the Seed 2.1 series on Volcengine in June, positioning Pro for exploring highly complex tasks and Turbo for large-scale production use. Compared with the previous generation, the company says Seed 2.1 improves coding delivery, long-chain agent task execution and multimodal understanding. The app is built around two modes that users can switch between freely: Chat and Work. In Work mode, users set a goal and attach files, images or material from their Doubao cloud drive, then choose Auto, Turbo or Pro and pick a reasoning intensity. They can also create projects, add local folders and set scheduled tasks. A side workbench supports new tabs, so a user can browse the web, read reference material and talk to Doubao at the same time while several tasks run in parallel. For content creation, the launch version includes deep research, PowerPoint generation, a writing assistant, image generation and cloud storage. Video generation, AI blogging, recording transcription, music generation and AI spreadsheets are also available. ByteDance pitches the client at office work, academic research, file management, automated tasks and creative design. HarmonyOS PCs run Huawei's own operating system rather than Windows, which means every mainstream application has to be rebuilt natively before users can install it. A general-purpose AI assistant has been one of the most visible gaps, and Doubao's arrival gives Huawei's laptop owners access to one of China's most widely used chatbots without relying on a browser. For ByteDance, the release extends Doubao's desktop presence beyond Windows and Mac, where the company has steadily turned its PC client into an agent that can operate software, run multi-step tasks and work across local and cloud files.

YouTubers' data scraping suit against ByteDance lives on.

YouTubers' data scraping suit against ByteDance lives on. The plaintiffs claim ByteDance bypassed YouTube's protections when accessing their videos, cheating them out of advertising revenue. SAN FRANCISCO (CN) - A federal judge ruled Friday YouTubers have standing in a suit accusing tech giant ByteDance of data mining their videos to train artificial intelligence models U.S. District Judge Jacqueline Scott Corley ruled that Ted Entertainment and Matt Fisher properly claimed at this stage that they've suffered what she called a pocketbook injury. Ted Entertainment, a company, and Fisher, an individual, create and post original content to YouTube and claim a large reason they chose the site was because of its protective measures, like forbidding people from data mining. "As one court already ruled in a similar suit brought by plaintiffs, '[a]s alleged, the barriers exist and require users to satisfy certain conditions before obtaining access," Corley, a Joe Biden appointee wrote. "Those barriers may be modest, perhaps by design given YouTube's business model, but they are barriers nonetheless. At the pleadings stage, plaintiffs' allegations are sufficient.'" The plaintiffs argued that ByteDance bypassed YouTube's protections, meaning their content didn't receive views that would have generated advertising revenue. ByteDance, the parent company of TikTok, is building several AI projects, which they want to turn language prompts into audiovisual content. To achieve that goal, the AI needs large amounts of data as training material - data that comes from the plaintiffs' work, they say. The plaintiffs claimed ByteDance violated the Digital Millennium Copyright Act, which enables a private right of action for someone who's been injured. However, ByteDance argued the plaintiffs had no injury, and therefore no standing. The supposed injury is the copying of materials used to train AI, not the circumvention of YouTube's security measures. The plaintiffs didn't properly claim an injury linked to that circumvention, ByteDance argued. Corley noted the plaintiffs made a handful of claims, including that the circumvention led to lost advertising revenue and lost YouTube Premium revenue. "Drawing inferences in plaintiffs' favor, plaintiffs 'lost per-view advertising revenue that YouTube's monetization system would otherwise have generated,'" the judge wrote, adding: "So, plaintiffs plausibly allege their pocketbook injury is directly traceable to defendant's circumvention sufficient to support standing." ByteDance cited what Corley called inapplicable cases in its defense which involved no monetary harm and had no focus on the link between the injury and statutory violation, leading to her decision in favor of the plaintiffs. Pivoting to the question of statutory standing, Corley wrote that plaintiffs under the Digital Millennium Copyright Act must fit within a group Congress has allowed to sue. ByteDance said the plaintiffs didn't meet that definition. That's because the private right of action is linked to the owner of the circumvented measure, not anyone who puts content on a platform like YouTube with its own controls. However, Corley wrote that the statute states "any person injured by a violation," as well as owners of protected material, fall within that group. The judge again found ByteDance's cited cases unpersuasive. "These cases thus reaffirm, rather than undermine, that copyright owners such as plaintiffs are at the very heart of the 'zone of interests' Congress sought to protect." Corley added. Attorneys on either side of the case couldn't immediately be reached for comment. Its weekly newsletter Closing Arguments offers the latest about ongoing trials, major litigation and rulings in courthouses around the U.S. and the world, while the monthly Under the Lights dishes the legal dirt from Hollywood, sports, Big Tech and the arts.

The Alliance for OpenUSD

AOUSD out and about - Q3 2026 community highlights.

AOUSD out and about - Q3 2026 community highlights. Home " AOUSD out and about - Q3 2026 community highlights. A quarter of momentum. Summer moved fast for the AOUSD community. Between new software releases, a packed SIGGRAPH program, and several new members, Q3 2026 highlighted the momentum of the OpenUSD ecosystem as it continues expanding into new areas and use cases. Here's what AOUSD members have been building, releasing, and presenting over the past three months. Growing the Alliance. AOUSD welcomed new General Members in July: ByteDance, Huawei, Physicl and Unity. Physicl joined as a contributor to the Physics Working Group, where it plans to help develop a normative physics schema so simulation data can move reliably between tools. ByteDance's arrival coincided with its participation in SIGGRAPH 2026, where it presented a workshop on efficient 3D content creation for immersive experiences. Unity's membership, meanwhile, brings another major real-time and game-development platform into the Alliance. AOUSD takeaway: New members from physics simulation, game development, and immersive media point to OpenUSD's reach well beyond its animation and VFX roots. Autodesk. Autodesk continues to expand its support for OpenUSD across its content-creation tools, including Maya and 3ds Max. Maya's new Dynamic Payloads bring more procedural flexibility to USD workflows. Artists can convert a Bifrost asset to USD while preserving its procedural capabilities. The result is an asset that stays lightweight, fully procedural, and easy to share. Watch the walkthrough and Bifrost release notes for more details. Maya and 3ds Max also picked up a new Path Editor that brings every path on a stage into one view for easier management, covered in the docs for Maya and 3ds Max. And in July, Khronos Group announced Autodesk's sponsorship of an open source glTF importer/exporter for 3ds Max, broadening interoperability between OpenUSD and other open 3D formats. AOUSD takeaway: Autodesk is deepening USD support directly inside its core content-creation tools while also investing in interoperability with adjacent open standards. Pixar. In July, Pixar helped deliver OpenUSD v26.08, bringing new features and improvements to the ecosystem. It later opened its newest RenderMan art challenge, Diorama Drama - running July 22 through October 19 and the first built around XPU. The challenge invites artists to build a character-centered story inside an isometric environment using USD models contributed by BigMediumSmall, KitBash3D, and Netflix/Tonko House, with shading, lighting, rendering, and compositing all in play and prizes including a Dell mobile workstation powered by AMD and NVIDIA. Then in July, Pixar and Autodesk jointly led an OpenUSD session at SIGGRAPH 2026 covering composition, rendering, physics, and other OpenUSD technologies. AOUSD takeaway: Between a new USD release and a challenge built on USD assets contributed by multiple studios, Pixar keeps investing in both the format itself and the creative community that uses it. NVIDIA. NVIDIA centered on connecting OpenUSD with agentic AI. In July, NVIDIA expanded its Agent Toolkit with new Omniverse libraries built on OpenUSD, giving AI agents the ability to inspect 3D scenes, generate sensor outputs, test physics, and convert CAD data into OpenUSD-based simulation-ready assets. NVIDIA also provided developer guidance on how AI agents can help teams prepare 3D scenes for simulation and develop lightweight USD runtimes. AOUSD takeaway: NVIDIA's work is a strong signal of where the ecosystem is headed, connecting OpenUSD with agentic AI so both developers and AI agents can build and validate 3D pipelines faster. PTC. PTC was highlighted this quarter for a multi-agent workflow that automatically prepares CAD models in OpenUSD for robotics simulation - an example of USD acting as the connective layer between design and physical AI. AOUSD takeaway: Industrial CAD-to-simulation pipelines are another sign that OpenUSD's role is expanding from content creation into engineering and robotics workflows. XGRIDS. This quarter's Meet the Visionary profile featured XGRIDS' Mindy Li on how the company connects LiDAR, imagery, point clouds, and 3D Gaussian Splatting data with visualization, simulation, digital twin, and physical AI workflows using OpenUSD - XGRIDS is also contributing to community work on representing large-scale 3DGS datasets and level of detail in OpenUSD. AOUSD takeaway: Reality capture and geospatial data are a real growth area for OpenUSD, extending the standard from synthetic 3D content into representations of the physical world. A widening ecosystem. These developments show just how much the OpenUSD ecosystem is broadening. Members are applying the standard across AI, developer tooling, reality capture, geospatial data, robotics, industrial workflows, and entertainment - bringing new use cases and perspectives into the community. At the same time, continued growth is bringing more organizations to the table to help shape where OpenUSD goes next. Q3 was a strong reminder that OpenUSD is becoming more than a way to exchange 3D data; it is helping connect workflows, tools, and industries around a shared foundation for interoperability.
