Video generation,
by the second.

Phosor is our video generation platform — text to video, image to video, lip-sync, motion transfer and custom LoRAs, through a web studio or an API.

We also make proofs cheap

Custom ASIC and software co-design for zero-knowledge proving — more than 20x the throughput of a GPU prover on the same workload, delivered into production hardware with Intchains.

How the hardware works →

  1. Post-training

    Where open video models actually fall short

    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.

  2. Post-training

    The open post-training toolbox for video

    Every published reward model and preference-optimisation method for video generation, ordered by what it costs and what it has been measured to buy.

  3. Model landscape

    MiniMax H3 and the open-weight frontier

    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.
