Baseten Loops goes GA with serverless SFT/RL training, per-token pricing

baseten · x · 2026-11-08

Baseten announced Loops is now GA with a serverless option. Teams at Ambience AI, Datadog, and LangChain use the Loops SDK for SFT and RL training. Serverless Loops features always-warm infra (no cold starts), pay-per-token pricing for both training and sampling, one-click deployment of trained checkpoints to production inference, and model-specific numerical validation to reduce train/sampling mismatch. Users bring data, reward functions, and training logic; Baseten handles infra and users keep full ownership of weights. A customer notes it enables a tight research feedback loop for continuous model improvement on massive data.
