Baseten launches Grid, Sandboxes, and Loops for AI infrastructure
Baseten announced three infrastructure releases: Grid enters public preview as a gateway, intelligent router, and guardrail layer for coding models; Sandboxes enter public preview as stateful, VM-isolated agent environments; and Loops becomes generally available for serverless supervised fine-tuning and reinforcement learning. The vendor said Grid is compatible with tools including Claude Code, Codex, OpenCode, and Pi, while Loops supports Tinker-compatible workflows and direct deployment through Dedicated Inference. Baseten also cited OpenEvidence, Datadog, and Opendoor as customers using different combinations of its training, inference, and routing products.
Baseten is positioning Grid, Sandboxes, and Loops as a connected platform spanning model routing, governance, agent execution, training, and production inference, according to the company.
