AI infrastructure on tap with the Pulumi AICR provider. Recently, some members of the Pulumi team spent time in San Francisco attending the CoreWeave: Fully Connected 2026 conference, where Pulumi had a chance to talk to everyone from solo developers to engineering leaders at Fortune 500 organizations and learn more about how they are building with AI. A frequent topic of conversation was open weight models and self-hosted inference. Whether AI is integrated into your platform, your product, or your productivity pipelines, rising token costs have decision makers everywhere giving open weight models a closer look, in exchange for the promise of tighter control over spend and greater domain expertise. If you are actively exploring the space or building with AI yourself, you may already have seen the challenges that come with serving inference at scale: * Model stability and reliability can differ (sometimes dramatically) across hardware architectures and at different traffic volumes. * Model performance and throughput can change depending on your workload type or model configuration. * Cost differences and commitments across providers can make tracking spend challenging. * Supply constraints and capacity shortages mean teams can't source hardware when they need it most. Many teams naturally gravitate toward multicloud strategies that combine hyperscalers with specialized GPU clouds as a way of balancing spend, performance, and reliability. One thing Pulumi has seen is that developers everywhere are choosing Pulumi to help them navigate the fragmented hardware ecosystem and maintain consistent environments, even when the provider is different. As part of its ongoing commitment to building better tools for builders, Pulumi is excited to announce the Pulumi NVIDIA AI Cluster Runtime (AICR) provider to help make your ideal self-hosted AI infrastructure available on demand. The Pulumi AICR provider lets you spin up workload-specific training and inference endpoints as you need them, configured with pre-validated recipes to match your workload with the right hardware across a number of cloud-based GPU providers. AI performance-engineering team as code. Deploying a cluster of GPU nodes as a production AI platform is a complex and time-consuming exercise that often requires specialized expertise. NVIDIA's AICR offers a collection of validated GPU infrastructure recipes for various cloud providers. By building a provider around AICR, Pulumi offers an efficient and reliable way to manage your GPU clusters, dramatically shortening time to first token. In addition to bundling a complex technology stack, Pulumi makes it simple to deploy with minimal verbosity. pulumi preview shows every component the recipe expands into (namespaces, operators, schedulers, metrics, training runtime) before anything is applied. pulumi up then deploys them as children of a single resource, with a full day-2 lifecycle: diff, update, drift detection, and destroy. This short Python snippet shows how easy it is to use AICR to deploy a simple pre-validated inference endpoint without wasting time or resources on guess-and-check configuration, so you can get started serving production traffic immediately. import pulumi import pulumi_labs_nvidia_aicr as aicr config = pulumi.Config service = config.get("service") or "lke" accelerator = config.get("accelerator") or "rtx-pro-6000" # The CoreWeave Kubernetes Service (CKS) kubeconfig is a plain token config downloaded # from the CoreWeave console and placed in the same directory as this script (gitignored). with open("kubeconfig.yaml") as f: kubeconfig = f.read gpu_stack = aicr.ClusterStack("nvidia-aicr", kubeconfig=pulumi.Output.secret(kubeconfig), accelerator=accelerator, service=service, intent="inference", nodes=2, skip_components=[ "gpu-operator", "nfd", "nvidia-dra-driver-gpu",], skip_await=True,) Deploying an inference endpoint to CoreWeave with the Pulumi NVIDIA AICR provider Behind the scenes, the recipe resolves the code into the full list of Kubernetes components. Recipes are tested and validated by NVIDIA across a broad matrix of both hardware (EKS, GKE, and AKS; A100 through GB200; Ubuntu, RHEL, COS, and Talos; Kubeflow, NIM, Dynamo, Slurm, and Run:ai) and cloud provider permutations. Because AICR is open source, the SDK lends itself to configuration by new providers, giving you a future-forward inference solution that performs in all of the areas that count: * Deployment: does the running cluster match the recipe? Operator health, GPU visibility via nvidia-smi, and metrics flowing. * Conformance: dynamic resource allocation, gang scheduling, and job-level networking behave as required. * Performance: NCCL all-reduce bandwidth for training; model throughput and latency for inference.

Bring your Terraform estate into the agentic era. At Pulumi, Pulumi is building the platform for agentic infrastructure. Pulumi Cloud provides the guardrails and enterprise readiness needed to safely move fast in this new era. While Pulumi is seeing extraordinary adoption - over 40% of its users now manage infrastructure using AI agents - Pulumi know many organizations are at different phases in their AI journey and have to balance building for the future with maintaining their existing infrastructure as code (IaC) solutions like Terraform. Today, Pulumi is launching three ways that Pulumi lets you avoid trading off building for the future against building for today. You don't have to rip out Terraform to enter the agentic era. Pulumi Cloud brings agentic infrastructure to the IaC estate you already have. What Pulumi is shipping today. Last December, its CEO Joe Duffy laid out his vision to make Pulumi the platform for all of your infrastructure as code. The capabilities Pulumi is launching today make that promise a reality. Pulumi is now fully interoperable with Terraform and OpenTofu and enables organizations to build upon their existing IaC estate rather than starting from scratch as they work toward the agentic infrastructure future. Pulumi Cloud as a Terraform backend. Pulumi is excited to announce the general availability of Pulumi Cloud as the backend to your Terraform state, enabling organizations to seamlessly lift and shift their existing Terraform estates. Pulumi recognize there is lots of infrastructure that works as is, and switching over to a new management paradigm may not always be possible. Pulumi Cloud support for the Terraform state backend lets organizations maintain their existing Terraform deployment patterns while also unlocking the power of Pulumi Cloud. The following common patterns for running Terraform are now supported: * Plans and applies run remotely by default for new Terraform stacks, following the behavior of HCP Terraform and Terraform Enterprise. When you run a Terraform operation, it executes on a Pulumi-hosted runner rather than your local machine. You get full visibility into these operations both on your local CLI and in the Pulumi Cloud console. * Production deployments may be gated with manual approvals before applying a Terraform plan. With this release, stacks with Terraform state are first-class entities in Pulumi Cloud. They get access to all of the capabilities that organizations need to scale in this new AI-first era. * Manage access to your Terraform stacks at scale using tag-based access control, team role assignments, and user role assignments. * Take advantage of Neo code reviews. On every pull request, leverage what Pulumi Cloud knows about your running infrastructure and get clear feedback on whether it's safe to merge changes to your Terraform and OpenTofu projects. * Run preventive policies after a Terraform plan to block non-compliant resources before deployment. * Configure your Terraform deployments with Pulumi ESC, which is natively available to Pulumi Cloud-backed Terraform projects, to securely inject OIDC credentials at apply time and expose outputs to downstream stacks and services. Reuse your Terraform modules. Pulumi programs, regardless of language, now support importing Terraform modules natively. Organizations can leverage their existing reusable artifacts as is, without having to make a single change. This enables organizations to focus on new infrastructure projects and lets them build those projects in the language of their choice, regardless of what their existing IaC estate is. In addition, Pulumi Cloud's private registry can now host Terraform modules alongside Pulumi packages. This enables you to consolidate all of your IaC building blocks in a single source of truth rather than managing disparate solutions and making sure your teams know where to look. Terraform modules hosted in Pulumi Cloud provide maximum interoperability and can be used in both Pulumi and Terraform programs. Build in HCL natively. HashiCorp Configuration Language (HCL) is now generally available as a first-class language in Pulumi IaC. Like any other Pulumi language, it has full access to the entirety of the Pulumi ecosystem, including thousands of providers. Thanks to its Terraform bridge, if there's a Terraform provider out there, it just works. Best of all, HCL in Pulumi is 100% OpenTofu compatible with no syntactical differences. Pulumi recognize there are many teams out there that prefer to work in HCL over general-purpose languages but want to leverage the modern Pulumi IaC engine, or want to be able to use the reusable components their partner teams rely on - regardless of whether those teams work in Terraform or Pulumi. You are still covered until your HashiCorp renewal. Pulumi stand by the promise Pulumi made last December, and the last thing Pulumi want is for you to pay for two IaC solutions. To set your team up for long-term success and ensure your transition to Pulumi is as smooth as possible, Pulumi is continuing to offer three things: * An escape hatch for your current contract. Pulumi know paying for two IaC solutions at once is a non-starter, so Pulumi is letting you apply credits purchased from HashiCorp toward your Pulumi usage until your next renewal, avoiding double pay. * A free IaC modernization workshop. Its professional services cloud architects host a free IaC modernization workshop to review where you're at with your IaC already and share best practices for adopting the Pulumi platform at scale, learned from working with world-class organizations like BMW and Supabase. You will leave this session trained up and equipped to succeed with the next phase of your IaC journey. * A return on investment (ROI) calculation. Pulumi will show you how the move to Pulumi will not only be spend-neutral thanks to the escape hatch, but how much value and savings you should expect to see, given its experience helping innovators like Snowflake accelerate their time to market - going from code to cloud in weeks to hours. These ensure there's no financial penalty for switching, a clear ROI, and no learning curve. Pulumi has always been proud to work with customers of all sizes in all industries, so these offers are available to you whether you're a Global 2000, a startup, or somewhere in between.
