An engineer on SpaceX AI's Grok team ships around 2,000 pull requests a month through an agent workflow called pstack. That's roughly 100 PRs a day (September 2026).
Do the math on human review: one person looking at every one of those gets five minutes per PR, for the whole month, and nothing else gets done.
Verification, not the model, is the actual ceiling on how fast agents can ship. An agent that can check its own work keeps going. An agent that can't turns every human reviewer into the bottleneck.
The part that's easy to miss: verification at that volume is also an infrastructure problem. Each attempt needs its own environment, running against real dependencies, ready in seconds, not minutes.
That's what *On-Demand Templates* and *Instance Forking* give you on our platform: boot once, absorb the heavy init, then stamp out a warmed VM in around 10ms, or transparently fork a running VM so a new attempt gets its own isolated copy instantly.
