For four years that meant zero-knowledge proofs and the ASICs that run them. Today it means video. Phosor, our generation platform, renders a second of 480p video for half a US cent — text to video, image to video, lip-sync, motion transfer, your own LoRAs, and an API with metered billing behind all of it.
16 frames = one second of generated video. At 480p turbo, that second costs $0.005.
Published rates, read from the platform's own pricing endpoint on 22 September 2026. Per-second figures are the published per-frame price at 16 fps. Full table →
Two lines of work
Proof generation and video generation are the same engineering problem wearing different clothes: an enormous arithmetic workload, a hard latency budget, and a cost per unit of output that decides whether anyone can afford to use it.
Open-weight video models — Wan 2.2, LTX, MiniMax H3 — served at metered prices, with LoRA training, e-commerce imaging and a short-drama workflow on top. It runs as Phosor, a platform you can sign up for today.
Custom silicon and software co-design for zero-knowledge proving: ZKVM accelerators reaching more than 20x a GPU prover on the same workload, delivered with partners into production mining hardware.
Research
Two tracks, one habit: every number carries a source, and every conclusion says what observation would overturn it.
The gap between open weights and the closed frontier is mostly post-training and data curation, not architecture. Here is the evidence, and what it costs to close.
Every published reward model and preference-optimisation method for video generation, ordered by what it costs and what it has been measured to buy.
Open weights reached the top of the human-preference leaderboard in August 2026. What that changes, and the three constraints that stop it being a clean win.
