Modelplane v0.2 is out. We open sourced the project three weeks ago, and since then
we've had a lot of traction and some great discussions with people running inference.
The mission driving each release is the same: Modelplane brings together the models,
engines, clouds, and accelerators that make up the intelligence ecosystem so you can
operate them as a single system under your control. And we are building this in the
open.

This release adds two more cloud providers, weighted request routing, and cluster
taints for reserving and draining capacity. Here's what's new.

## More providers

At launch, Modelplane provisioned inference clusters on GKE and EKS, or ran on any
Kubernetes you brought yourself. v0.2 adds two more providers, [Nebius](https://nebius.com) and
[Azure AKS](https://azure.microsoft.com/en-us/products/kubernetes-service). A Nebius
cluster is about as much YAML as it sounds like it should be. You name it, point it at
Nebius, and Modelplane provisions the rest from the credentials you already configured:

```yaml title="nebius-cluster.yaml"
apiVersion: modelplane.ai/v1alpha1
kind: InferenceCluster
metadata:
name: nebius-eu-north
labels:
modelplane.ai/region: eu-north
spec:
cluster:
source: Nebius
nebius: {}
nodePools:
- name: gpu-h100
className: nebius-h100-8x
nodeCount: 1
minNodeCount: 1
maxNodeCount: 4
```

Both work the same way as GKE: an `InferenceClass` describes the hardware, an
`InferenceCluster` provisions it, and the same `nodePools` model applies. On GKE, the
GPU node pools Modelplane creates now cold-start from zero, so an idle pool stops
billing you when nothing is running on it.

You can also still bring your own cluster on any Kubernetes, on any cloud or on-prem,
for providers Modelplane doesn't provision yet. If you want a provisioner for a
particular cloud, upvote or open an
[issue](https://github.com/modelplaneai/modelplane/issues).

## Weighted routing

A `ModelService` can now split traffic across its endpoints by weight:

```yaml title="model-service.yaml"
apiVersion: modelplane.ai/v1alpha1
kind: ModelService
metadata:
name: qwen
namespace: ml-team
spec:
endpoints:
- weight: 95
selector:
matchLabels:
modelplane.ai/deployment: qwen3-8b
- weight: 5
selector:
matchLabels:
modelplane.ai/deployment: qwen3-8b-v2
```

Weights are relative, and an endpoint with no weight defaults to 1. The endpoint stays
fixed while you change the split, which covers canarying a new model version, shifting
traffic between two deployments, and splitting between a hosted provider and your own
deployment. Weights are the first step here, and there's a lot more routing
functionality on the way.

## Taints and draining clusters

v0.2 also lets you decide which clusters take work, using the same taints and
tolerations that Kubernetes already uses for nodes, lifted up to the cluster. You taint
an `InferenceCluster`, and only models that tolerate the taint will schedule onto it:

```yaml title="reserve-cluster.yaml"
apiVersion: modelplane.ai/v1alpha1
kind: InferenceCluster
metadata:
name: gpu-us-east
spec:
taints:
- key: modelplane.ai/reserved
effect: NoSchedule
```

This is useful for keeping a sovereign cluster, or one with scarce hardware, for the
workloads that need it. A deployment opts in with a matching toleration under its
template:

```yaml title="model-deployment.yaml"
apiVersion: modelplane.ai/v1alpha1
kind: ModelDeployment
spec:
replicas: 2
template:
spec:
tolerations:
- key: modelplane.ai/reserved
operator: Exists
```

The same mechanism drains a cluster. Taint it with `NoExecute` instead of `NoSchedule`
and Modelplane moves the running replicas off onto other clusters in the fleet, so you
can take a cluster out for maintenance without hand-migrating what's on it. Remove the
taint and it takes work again.

The full release notes are on
[GitHub](https://github.com/modelplaneai/modelplane/releases/tag/v0.2.0), and the
[getting-started guide](https://docs.modelplane.ai/getting-started/) now covers
deploying on AKS and Nebius. Questions and feedback are welcome in
[Slack](https://slack.modelplane.ai).
