Baseten acquires Blaxel to add 25ms-resume agent sandboxes to its inference cloud
saranormous · x · 2026-09-11
Inference platform Baseten acquired agent sandbox company Blaxel, aiming to build "the cloud for the next trillion agents." Key points:
- Median inference calls have changed: coding agents loop on patches and tests, RL rollouts need execution environments — sandboxes are now core infra
- Blaxel offers per-agent microVMs, persistent storage, and suspend/resume in 25ms (up to 5x faster than rivals); idle sandboxes cost near zero for months
- Customer Sapiom runs hundreds of millions of agent loops on Blaxel
- Thesis: tomorrow's cloud merges inference, training, and sandbox execution in one platform
