What is warm start?
A warm start begins work in an environment where dependencies are installed and caches are populated, so the first command you run is the one you care about.
The industry benchmarks cold start because it is easy to measure and easy to market. It is also converging, with a floor of tens of milliseconds.
The warm path still differs by an order of magnitude. A typecheck that takes 24.35 s cold takes 1.55 s warm; another goes from 101.4 s to about 1.5 s. Across a twenty-cycle agent task that is 527 s against 71 s for identical work.

Run your own workload on it, free
Send a repo and the command you run against it, whatever that is: an eval suite, an RL rollout, a CI job, a queue of coding tasks. We build the environment once, run it a thousand times, and send back the timings, the failures and an exact price. Free, once, on your real workload.
- 1,000 runs of your own command, on your own repo
- What each one cost in wall clock, and anything that failed
- Whether a failure was your code or the environment
- An exact price for your real volume
