KServe

Unified AI inference platform for generative and predictive workloads on Kubernetes

KServe delivers scalable, multi‑framework AI inference on Kubernetes, supporting LLMs, GPU acceleration, model caching, autoscaling, explainability, and cost‑efficient serverless deployments.

Overview

Overview

KServe is a Kubernetes‑native platform that consolidates generative and predictive AI inference into a single service. It enables data‑science and MLOps teams to deploy large language models, TensorFlow, PyTorch, XGBoost, ONNX and other frameworks with a consistent API, while leveraging Kubernetes and Knative for reliability and scalability.

Capabilities

The system offers GPU‑accelerated serving, KV‑cache offloading, intelligent model caching, and request‑based autoscaling that can scale to zero for cost savings. Advanced routing lets you compose predictors, transformers, and explainers into inference pipelines, support canary rollouts, and monitor drift or adversarial inputs. Integration with Hugging Face and OpenAI‑compatible endpoints simplifies LLM deployment, and built‑in explainability tools provide feature attribution for predictive models.

Deployment

KServe can be installed as a lightweight standalone component, with Knative for serverless features, or alongside ModelMesh for high‑density, high‑scale serving. It is an incubating CNCF project and integrates tightly with Kubeflow, making it suitable for both cloud and on‑premise Kubernetes clusters.

Highlights

Request‑based autoscaling with scale‑to‑zero

Pros

  • Unified platform for generative and predictive AI
  • Native Kubernetes and Knative integration
  • Extensive framework and model support
  • Built‑in autoscaling and cost‑saving features

Considerations

  • Complexity may increase for small‑scale deployments
  • Serverless features require Knative installation
  • Advanced capabilities need deeper Kubernetes expertise
  • Limited support for non‑Kubernetes environments

Fit guide

Great for

  • Enterprises needing scalable AI inference across multiple frameworks
  • Teams deploying large language models with GPU acceleration
  • MLOps pipelines requiring model explainability and traffic management
  • Organizations aiming to reduce inference costs via scale‑to‑zero

Not ideal when

  • Simple, single‑model deployments on bare‑metal without Kubernetes
  • Projects lacking Kubernetes or Knative expertise
  • Use cases requiring on‑premise inference outside container orchestration
  • Environments where licensing restrictions prevent Apache‑2.0 usage

How teams use it

Real‑time LLM chat service

Delivers low‑latency responses with GPU acceleration, KV‑cache offloading, and autoscaling to handle variable traffic.

Batch predictive scoring for fraud detection

Scales to zero when idle, routes requests through explainability components, and integrates TensorFlow and XGBoost models.

A/B testing of model versions

Uses canary rollouts and InferenceGraph to compare predictions while minimizing risk.

Multi‑tenant model marketplace

Leverages ModelMesh for high‑density serving of many models with intelligent caching and resource isolation.

Frequently asked questions

Does KServe require Knative?

Knative is installed by default for serverless deployments; a lightweight standalone mode is also available without Knative, but it lacks canary and scale‑to‑zero features.

Which machine‑learning frameworks are supported?

KServe supports TensorFlow, PyTorch, scikit‑learn, XGBoost, ONNX, and additional frameworks via custom containers.

How does autoscaling work for generative models?

KServe provides request‑based autoscaling that monitors GPU utilization and can scale pods up or down, including scale‑to‑zero for predictive workloads.

Can I use Hugging Face models directly?

Yes, KServe includes native support for Hugging Face model formats, simplifying deployment with a single InferenceService definition.

Is model explainability available out of the box?

KServe includes built‑in explainer components that generate feature attributions and other explanations for supported model types.
