Key point
Baseten launches Grid, Sandboxes, and Loops to extend its inference platform with routing, execution, and training capabilities.
Details
- Baseten launches three product milestones: Grid (gateway, router, and guardrails), Sandboxes (stateful, VM-isolated execution), and Loops (serverless training).
- Grid acts as a single control layer for coding spend, routing tasks to the best model based on cost, quality, and KV cache hit rate.
- Loops provides serverless SFT and RL on frontier open-weight models, allowing teams to post-train and serve models directly as production endpoints while retaining weight ownership.
- Sandboxes offer stateful, pause/resumable, VM-isolated environments that scale to thousands of instances in seconds, co-located with inference for better performance.
- Grid launches as a public preview; Sandboxes move from private to public preview; Loops becomes generally available on Friday.
- The platform runs on Multi-cloud Capacity Management across dozens of clouds, delivering 99.99% uptime.
