Products

Selected offerings — the AI products recorded here, not the vendor's full catalogue.

• Baseten Platform Sold on its own

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

• Baseten Model APIs Model API Sold on its own

  Pre-optimised hosted endpoints for open-source frontier models, called without deploying or managing a deployment first.

• 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).

Inside Baseten

• Baseten Training Platform Included with the parent

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

• Baseten Inference Runtime Infrastructure service Included with the parent

  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.
