A single cluster can sustain 50,000+ concurrent sandboxes with sub-second launch times via warm pools. The post includes a full RL post-training example using sandboxed reward scoring, a Python async SDK walkthrough, and head-to-head benchmarks against Modal showing ~20% faster p50 latency and up to 10x cost reduction. Code and data never leave your cloud, and secrets are injected at runtime rather than baked into images. ## Full article daily.dev links to this article rather than hosting it.
