AICR v1.0: Open, stable, and verifiable GPU cluster configuration | NVIDIA Technical Blog

The v1.0 release of NVIDIA AI Cluster Runtime (AICR) establishes a stable compatibility contract across its CLI, REST API, Go SDK, bundle layout, and artifact schemas. This release introduces merge-blocking checks for public integration surfaces and defines semantic breaking changes for future releases. It also enhances the validation dashboard to display published evidence for each supported recipe, including test results and signatures. Integrations with Pulumi Labs and Mirantis's k0rdent are highlighted, demonstrating the consumption of AICR configurations through different tools. The post details AICR's four core capabilities: Snapshot (recording observed state), Recipe (describing desired configuration), Bundle (rendering deployment artifacts), and Validation (verifying running clusters against recipes with signed evidence).
