- [00:00:30] Intro: Eden welcomes Zeev & the real-time, on-device video breakthrough
- [00:01:36] Why LTX-2 matters: multimodal → one model, many outputs
- [00:02:24] Transformers converge: no more “image model vs video model” silos
- [00:03:34] Programmable pixels: the real value is real-time, user-responsive video
- [00:04:30] China’s edge: open weights, edge-first strategy, Alibaba leading
- [00:06:27] Israeli startups standardizing on Chinese stacks (Qwen, G-PIO)
- [00:08:40] Product → Platform: Lightricks restructures into model + API + apps
- [00:11:02] Foundation models depreciate fast; value shifts to productization
- [00:13:23] Gaming-engine analogy: model = rendering core, tooling = moat
- [00:19:25] Real-time personalized ads: creative per user, per impression
- [00:24:21] LLM → JSON pipelines: APIs replaced by structured scene instructions
- [00:31:31] Cost shift: state-of-the-art video running on consumer GPUs, not data centers
What if video wasn’t a file you export, but a service that responds to every viewer in real time?
In this episode, Eden Shochat talks with Lightricks co-founder & CEO Zeev Farbman about LTX 2, their real-time video diffusion model that runs on edge devices (phones and gaming GPUs) instead of giant cloud data centers.
They break down:
- Why “every pixel is programmable” is the real story behind diffusion models
- How we got from Facetune to a real-time video engine
- Why edge AI might beat cloud APIs for the next wave of products
- China’s open-weight strategy vs the West’s closed, API-first approach
- What happens when you can personalize every ad impression with generated video
- Why foundation models are a fast-depreciating asset and where the real moats will be
- How Lightricks thinks about being both a product company and a platform/API
- The coming shift from blank 3D scenes to “never start from scratch” creative workflows
- The sci-fi idea from Neal Stephenson’s Diamond Age that Zeev would build as a startup today
If you’re a founder, engineer, or creator thinking about the future of video, gaming, or adtech, this episode is a playbook for what’s now possible when real-time, per-user video runs on everyday hardware.
