Inferred 2026-09-08, not read off a page: every already-decided product of type 'model-api' in this catalogue includes "saas" in its deployment list, zero exceptions, per item 198's measured cross-tab. May be incomplete if this product also offers a self-hosted or private-cloud option; not wrong either way.

• Baseten Platform

  Deploys and serves machine-learning models as production endpoints on managed GPU infrastructure.

• Baseten Training Platform

  Trains and fine-tunes models with reinforcement learning through the Loops SDK, deploying the result onto Baseten's inference stack.

• Baseten Frontier Gateway API service

  Production-grade API launch platform for model labs: takes a lab's model from research to a reliable, scalable, white-labelled API in days, distinct from Baseten's Distribution Platform (model marketplace listing).

• Baseten Inference Runtime Infrastructure service

  Named inference runtime (automatic TensorRT/SGLang/vLLM builds, speculative decoding, custom kernel fusion, KV-cache optimisation) that underlies Baseten's Dedicated Inference, Model APIs and Training products.
