spin up a short-lived Python sandbox to run agent-generated code
get a GPU sandbox for a longer compute job

Not for

not free, no refund on early termination once hourly billing starts

Inputs

POST JSON body, all optional: cpu (number), gpu (enum T4|L4|A10G|A100|H100), image (string, only python:3.11), memory (MB), timeout (seconds, max 86400).
