The models' case: The default CI for the majority of cloud-native teams because it lives where the code already is — massive marketplace of reusable actions, first-class container/K8s. The models' main caveat: It is CI-only in practice — no real deployment orchestration, environments, or GitOps story, so serious Kubernetes CD means bolting on Argo CD or. The strongest alternative is GitLab CI/CD — Best end-to-end balance: mature pipelines, container registry, security scanning, environments, Kubernetes runners, deployment controls, and credible. Not unanimous: ChatGPT picks GitLab CI/CD.
