The verdict

GPT #1Claude #1Gemini #1Grok #1
Best node autoscaler for modern Kubernetes: fast just-in-time provisioning, flexible instance selection, bin-packing, consolidation, spot/on-demand cost optimization, and strong production maturity especially on EKS
What would move Karpenter up
- GPT Make non-AWS provider support as mature and predictable as its AWS experience
- Claude Reach true first-class multi-cloud parity (GCP and on-prem providers are still immature), so it's the default everywhere instead of mainly on AWS
- Gemini Achieve full out-of-the-box maturity and parity on GCP and Azure without relying on community-maintained provider workarounds.
- Grok deliver mature first-class production support for GCP and other non-AWS clouds at parity with its AWS leadership
