    "title": "The Next Medium: Why Real-Time Interactive Video Changes Everything — Ahmed Ahres, Reactor",
    "one_liner": "Reactor's Ahmed Ahres argues that \"world models\" are best defined as real-time interactive video — infinite, promptable, sub-100ms video you can change while it plays — and that this ends the \"slot machine\" of batch video generation the way GPS enabled Uber and digital viewfinders enabled Instagram and TikTok.",
    "summary": "Ahres reframes world models away from gaussian splatting and marketing hype into a concrete definition: real-time interactive video, where pixels are generated continuously and can be addressed, conditioned and changed like software. He traces two historical precedents — maps→GPS→Uber, and film→digital viewfinder→Instagram/TikTok — to argue that real time doesn't just make a medium faster, it changes what the medium is. He then maps the market into three model types (real-time Veo/Sora-style infinite video, Genie 3-style controllable worlds, and live interactive avatars), shows what Reactor's users build with them, and explains why real-time inference infrastructure is a different ballgame from batch: streaming, live sessions with memory, and worldwide GPU placement.",
    "key_points": [
      "Definition: world models = real-time interactive video. Today's generated video (Veo 3, Seedance 2 — ASR 'Cense 2') is \"still a recording\": prompt, get a file back, watch, and you can't change it.",
      "Real time changes the medium rather than merely speeding it up — GPS made location real time and Uber became possible; the digital viewfinder let you see what you were shooting and Instagram/TikTok became possible.",
      "Model type 1: Veo/Sora-like but infinite (doesn't stop at 5, 10 or 30 seconds), interactive and real time. Live demo: an image of a dog generated in real time, then a mid-stream prompt makes a cat appear — impossible in batch generation. Unlocks control (\"instant feedback is the ultimate level of control\") and, eventually, ads generated live around what you just looked at, with no pre-production.",
      "Model type 2: Genie 3-style — pass an image plus text, control a character. Goes beyond games into Bandersnatch-style interactive game/movie hybrids, robotics (infinite simulated training data; Ahres calls world models in robotics a \"ginormous market\" today), and education — he doesn't believe the future of education is LLM-based or textbook-based, but stepping into e.g. a history lesson.",
      "Model type 3: live interactive avatars, now appearing in research preview. Avatars \"hasn't actually been cracked\" — customer support avatars still feel off — but combined with types 1 and 2 they target support, training, sales, gaming and streaming.",
      "What Reactor users actually build: interactive live streams where viewers type and vote on what happens next (X, YouTube, Twitch), medical simulation (\"what if I put this medicine?\") as doctor-training playgrounds, cooking simulation, and real-time video editing/VFX platforms — the editing ones \"not very good yet just because of the quality of the models.\"",
      "Reactor serves four models behind one API: Helios (interactive video, from ByteDance), Lingbot (Genie 3-style world model trained by Alibaba), Long Live 2 from Nvidia (multi-shot film — prompt shots in advance for a consistent story over time), and a video-to-video editing model from Nvidia (transcribed as \"sound streaming\"), used for adding VFX, removing people and swapping backgrounds — interesting for Hollywood previsualization.",
      "Real-time infra ≠ batch infra: you must stream pixels server→client; everything is a live session so memory/context must be maintained (Genie demos show characters looking back and forgetting); and you need sub-100ms latency globally, routing a user in India or Japan to a nearby GPU or \"it breaks completely the medium.\"",
      "Open problems, from Q&A: evaluation of real-time world models is unsolved — \"literally just look at it and human judgment,\" including at Google DeepMind. Reactor does no deterministic rule-checking to keep simulations consistent; the community builds and open-sources that on top. Latency/cost levers are multi-GPU, optimized model weights and quantization."
    ],
    "takeaways": [
      "Stop treating generated video as a deliverable file and start treating it as a stream you can address, condition and change mid-flight — that's where the control content creators keep asking for actually comes from.",
      "Don't port batch video-generation infrastructure to real time. Design for pixel streaming, long-lived sessions with an explicit context window for memory, and GPUs placed close to users so you hold sub-100ms latency worldwide.",
      "Try the three model families as distinct building blocks — real-time infinite video, controllable-character world models, live avatars — and consider combining them; Reactor's users get interactive live streams, medical and cooking simulators and VFX editors out of the combinations.",
      "If you're building on world models, expect to supply your own evaluation and your own deterministic guardrails: nobody, including DeepMind, has a solved eval for real-time consistency, and Reactor's platform doesn't check against rule sets.",
      "Getting started is roughly 10 lines of code — load the model with an API key; the talk offers promo code AIE 2026 for $75 of credits."
