What it sells
World model.
Business model breakdown
Buyer: who owns the budget?
UnverifiedDevelopers and engineering teams at companies building interactive/generative-video apps (e.g. games such as Overworld) and model builders who want to host their own world models.
Trigger: what makes them buy now?
Need for real-time interactive generative media at production latency without managing GPUs; site claims sub-50ms end-to-end latency vs a 400ms+ industry average.
Workflow: what inputs become what output?
Connect to a model through the SDK, receive live video, send commands to steer generation while it runs; model builders port a ReactorApp, run `reactor model deploy`, and Reactor serves it on its GPUs.
Economics: what it saves and how it charges
Pay-as-you-go billed per second of GPU session time, no subscription or seat fee.
Distribution: how it reaches customers
Self-serve developer signup with free starting balance; Reactor Serve is by invitation (private beta).
