At TwitchCon San Diego, the Israeli startup Decart staged a live demonstration of something I\u2019ve not seen before: real-time generative AI video. Partnering with Los Angeles\u2013based Geenee AR, the company installed its system inside Geenee\u2019s Magic Mirrors. Attendees could see themselves transformed on screen into different clothes, settings, or entire worlds, all rendered live, tracking them as they moved. The system\u2019s latency measured under forty milliseconds, fast enough to maintain full 1080p motion without visible delay.<\/p>\n
TwitchCon draws tens of thousands of streamers and fans who already work and play in real time. Their broadcasts unfold without editing or retakes. This audience, CEO Dean Leitersdorf said, is Decart\u2019s proving ground. \u201cThey don\u2019t storyboard,\u201d he told me. \u201cThey improvise. Our AI needs to be just as fast.\u201d Decart\u2019s adds an AI layer to the camera software so streamers can prompt as they go. <\/p>\n

DecartStream, the company\u2019s first public product, drops into OBS as a browser source, the same software most Twitch streamers use. It adds a new control layer where a creator types a prompt like \u201cmake the room pink,\u201d \u201cadd a dog,\u201d \u201cchange my outfit,\u201d and the video adjusts midstream. Leitersdorf says this differs fundamentally from tools like Snap Camera, which rely on prebuilt filters. \u201cWe don\u2019t apply overlays,\u201d he said. \u201cWe regenerate the video itself.\u201d The model reimagines the frame each instant while preserving motion and coherence, something Snap\u2019s static effects cannot do. <\/p>\n
The technology behind the system, Live Stream Diffusion, is a custom autoregressive model trained for continuous inference. Leitersdorf described it as \u201cAI with a reflex.\u201d Decart\u2019s system is both lighter and cheap enough to do this because it was built from the ground up for speed. \u201cWe write below CUDA (Nvidia\u2019s proprietary software layer), down to GPU assembly,\u201d Leitersdorf said. \u201cThat\u2019s how we keep latency under forty milliseconds.\u201d<\/p>\n
Founded in 2023, Decart has raised about $150 million from Sequoia, Benchmark, and other venture firms. The company employs roughly eighty people in Tel Aviv, San Francisco, New York, and Switzerland. Leitersdorf, who completed his PhD in distributed computing at the Technion at 23, says Decart\u2019s focus is still research. \u201cWe\u2019re building infrastructure for live creation,\u201d he said. \u201cRevenue comes later.\u201d<\/p>\n
The lack of a business model appears intentional. Decart\u2019s first year of income came from licensing its GPU optimization layer to labs and chip providers, work that funds its new products. By driving down compute costs, Leitersdorf said, the company can afford to distribute its creative tools free while it grows a developer and streamer base. He estimates only a small fraction of its $150 million has been spent so far. \u201cWe burn less than ten percent,\u201d he said.<\/p>\n
That strategy mirrors the Twitch ecosystem itself, which grew on free access and community participation. At TwitchCon, Leitersdorf observed how tightly knit that culture remains. \u201cPeople here build relationships through their streams,\u201d he said. \u201cIt\u2019s a conversation, not a newsfeed.\u201d He described the Twitch environment as an economy of attention where users, creators, and moderators co-create the experience. By giving them generative control of their own feeds, Decart wants to make the medium more responsive to both sides of the screen.<\/p>\n
Twitch streamers who tested DecartStream before the event began posting clips that quickly spread on X and TikTok. The company says thousands of developers worldwide are now experimenting with its API for games, virtual production, and interactive shows. Leitersdorf believes the same infrastructure could support multiplayer worlds where the environment reacts to dialogue or viewer input.<\/p>\n
At TwitchCon, surrounded by creators who already live inside their broadcasts, Decart\u2019s system fit naturally. Its AI doesn\u2019t wait for an edit. It works inside the moment, adjusting faster than the human performing for the camera. In a community built on constant live exchange, Decart\u2019s pitch was simple: this is AI that moves at the speed of Twitch.<\/p>\n","protected":false},"excerpt":{"rendered":"San Diego, CA.
