Deploy Smarter

Scale Freely

Seldon Core 2 is a modular, data-centric framework that gets models into production at scale. Designed to work stand-alone or complement SageMaker, Seldon fills common innovation gaps to help teams move faster with confidence.

At a Glance

Sagemaker

Seldon

Startup Performance

Notebooks take ~5 minutes to start; JupyterLab Spaces up to 30 minutes. Cold starts interrupt workflows and slow iteration.

Lightweight architecture with near-instant startup and consistent performance across restarts. Developers stay in flow.

Cost Efficiency

40% higher than EC2 equivalents. Always-on endpoints with no scale-to-zero mean you pay for idle compute.

Scale-to-zero and multi-model serving cut costs dramatically. Transparent pricing with no hidden data or storage fees.

Deployment Flexibility

Fully tied to AWS. Deployments depend on AWS infrastructure and services, limiting portability.

Cloud-agnostic and Kubernetes-native. Deploy across AWS, GCP, Azure, on-premise, or edge, with full portability.

Monitoring & Observability

Basic latency and error metrics only. Logs are fragmented across CloudWatch and lack diagnostic depth.

Centralized monitoring with drift/outlier detection, request tracing, and detailed diagnostics in one unified view.

Experimentation & Model Serving

Static A/B testing with limited routing. No dynamic optimization or automated rollbacks.

Advanced traffic control (multi-armed bandit (MAB), shadow, canary) and rollback automation. Faster, safer experimentation at scale.

Developer Experience

Complex setup with IAM, VPC, and lifecycle scripts. Local mode behaves differently from production.

GitOps-native workflow with true local development and consistent environments. Simple, fast, and intuitive.

Governance & Compliance

Basic registry and versioning. Lacks approval workflows, lineage tracking, and audit trails.

Full governance with version control, approval flows, and enterprise-grade auditability for compliance.

Data Integration

Requires data in S3. Limited connectivity with external warehouses and data lakes.

Direct integration with diverse data sources, no forced data migration or duplication.

Resource Management

Manual scaling and rightsizing. Frequent GPU availability and quota issues.

Automated scaling and optimization across clusters. Multi-cloud fallback ensures availability.

Security & Access Control

Complex IAM setup and shared responsibility confusion. REST-only endpoints.

Simple, unified security model with fine-grained permissions and multi-protocol support (REST, gRPC, GraphQL).

Built for the Future of Machine Learning and AI

With its modular, data-centric design, Seldon Core 2 brings flexibility, standardization, and performance together, empowering businesses to optimize every stage of their ML lifecycle.

Innovate Freely

Freedom to build and deploy ML your way, whether on-prem, in the cloud, or across hybrid stacks.

With support for traditional models, custom runtimes, and GenAI frameworks, Seldon fits your tech, your workflows, and your pace without vendor lock-in. 

Learn Once, Apply Everywhere

Scale confidently with a unified deployment process that works across all models, from traditional ML to LLMs.

Seldon eliminates redundant workflows and custom containers, enabling your teams to launch faster, reduce errors, and scale ML consistently.

Zero Guesswork

Get real-time insights into every model, prediction, and data flow no matter how complex your ML architecture.

From centralized metric tracking to step-by-step prediction logs, Seldon empowers you to audit, debug, and optimize with complete transparency.

Efficient by Design

Modular framework scales dynamically with your needs, no overprovisioning, no unused compute.

Features like Multi-Model Serving and Overcommit help you do more with less, cutting infrastructure costs while boosting throughput. 

Explore Core 2

Core 2 is a modular framework with a data-centric approach, designed to help businesses harness the growing complexities of real-time deployment and monitoring.

Core 2 Architecture

Seldon Core 2 leverages a microservices-based architecture with two layers:

Manage inference servers, model loading, versioning, pipeline configurations, running experiments, and operational state to ensure resilience against infrastructure changes

Handle real-time inference requests using REST and gRPC protocols with the Open Inference Protocol (OIP) and are powered by Envoy for intelligent routing

 

It also enables interoperability and integration with CI/CD and broader experimentation frameworks like MLflow by Databricks and Weights & Biases.

Seldon Ecosystem

The Seldon ecosystem streamlines model deployment, monitoring, and governance for data-critical use cases like fraud detection, search, and personalization.
