Products, side by side
Algorithmic pairing — assembled from recorded fields, not hand-checked
Baseten
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.
Model API
Pre-optimised hosted endpoints for open-source frontier models, called without deploying or managing a deployment first.
Nebius Group
Infrastructure service
Nebius-managed Kubernetes operator that runs Slurm clusters on GPU infrastructure for fault-tolerant large-scale AI training, with topology-aware scheduling and automatic node health checks and recovery.
Rented GPU clusters with storage and networking for training and serving models, billed by the GPU-hour.
Nebius AI Cloud's on-demand GPU runtime that runs containerised AI workloads as Jobs and hosts custom models behind HTTP Endpoints without provisioning or managing clusters.
Model API
Managed inference endpoint serving open-weight models on Nebius hardware, billed per token.
No counterpart
Baseten sells these in a stack layer with no product recorded for Nebius Group yet — nothing on the other side to compare them against.
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).
Platform
Deploys and serves machine-learning models as production endpoints on managed GPU infrastructure.
Trains and fine-tunes models with reinforcement learning through the Loops SDK, deploying the result onto Baseten's inference stack.
Nebius Group sells these in a stack layer with no product recorded for Baseten yet — nothing on the other side to compare them against.
Developer tool
Fully managed MLflow deployment on Nebius AI Cloud for tracking experiments, metrics and artifacts across the machine-learning lifecycle without maintaining tracking-server infrastructure.
