Your engineers spend too much time on infrastructure upkeep

Cast AI rightsizes workloads, provisions nodes from your node templates, and consolidates underused ones, all within the policies you set. When a fix belongs in code, such as Helm values or Terraform, it opens a pull request for your team to review.

You pay for capacity your workloads never use

Cast AI sets each workload’s CPU and memory requests from observed usage, then bin-packs pods onto fewer, better-fitting nodes and moves eligible workloads to spot instances. Your node count follows real demand instead of peak requests.

The GPUs you need aren't available where you run

When your region runs out of GPUs, Cast AI provisions nodes in other clouds and regions through OMNI Compute and schedules eligible workloads there, while your control plane stays in your current cluster. For GPUs you already have, time-slicing and MIG let several workloads share one device.

Full disks crash your apps, and throttled disks slow them down

Cast AI expands volumes before they fill and tunes IOPS and throughput on supported disks in GKE and EKS. It starts in dry-run mode, so you review every change first.

Your database is slow and overloaded

Cast AI’s Database Optimizer sits in front of PostgreSQL and MySQL. It caches repeated reads, pools connections so traffic spikes don’t exhaust your connection limit, and flags slow queries with suggested fixes.

You don't trust automation with production yet

Cast AI starts in read-only mode, so you can review recommendations on selected clusters first. Once you enable changes, Cast Radar reports show cost next to error rate and latency (P50, P95, P99), so you can verify the savings came without a performance hit.

Cast AI observes, decides, and acts

It reads how your workloads and nodes behave, works out what should change, and applies eligible changes to live infrastructure within your policies. When a change belongs in your repo, it opens a pull request for your team to review.

Observe and decide

Workloads and nodes, tuned together

Workload rightsizing informs node capacity, bin-packing, and placement. Node conditions and available capacity inform workload adjustments and remediation. Cast AI connects both while preserving existing policies and integrations.

Keep your existing Cluster Autoscaler, Karpenter or use Cast AI's native autoscaler.

Act at runtime

Change it live

Resize workloads, add nodes, move pods, and grow volumes, within your policies, where your setup supports it.

Act in code

Fix the source

When a change belongs in code or configuration, Kimchi agents open a pull request. Your team reviews and merges, and your CI/CD ships it.
