Baseten Loops goes GA with serverless post-training: SFT and RL where you own the weights
baseten · x · 2026-11-07
Baseten announced that its post-training platform Loops is now GA and available serverless, tapping into the trend of companies increasingly owning their models. Teams at Ambience AI, Datadog, and LangChain already use the Loops SDK for SFT and RL training to build custom, durable intelligence.
Serverless Loops features:
- Always-warm infrastructure that eliminates cold starts
- Pay-per-token pricing for both training and sampling
- One-click deployment from a trained checkpoint to production inference
- Model-specific numerical validation, focused on reducing train/sampling mismatch
The pitch: you bring the data, reward functions, and training logic; Baseten handles infrastructure, and you always own the weights.
