1. Realtime factor
Realtime factor equals generation latency divided by output duration. A five-second clip generated in three seconds runs at 0.6× realtime and can build a playback buffer.
CORE FORMULAEffective cost = attempt cost ÷ acceptance rate
2. Buffer before you stream
Faster-than-realtime inference does not remove queue spikes, safety checks or failed jobs. Keep multiple approved clips ready and define a fallback loop.
3. The 24-hour cost trap
Continuous generation multiplies small per-second prices by 86,400 seconds per day. Interactive streams should generate only when needed, reuse buffers and seek sponsorship before scaling.

Frequently asked questions
Does faster than realtime mean zero delay?
No. It describes inference throughput, not queueing, upload, moderation or playback latency.
