Best Serverless GPU Providers in 2026

Serverless GPU infrastructure has become an important option for teams that need elastic AI compute without directly managing clusters. It is one deployment model among several: dedicated instances, managed Kubernetes, reserved clusters, and marketplace VMs remain viable depending on utilization, topology, latency, and training requirements. RunPod itself separates Pods, Serverless, and Clusters for different workload classes, and Nebius positions its serverless products alongside orchestrated training infrastructure. Whether you're deploying model inference at scale, running distributed training jobs, or executing massively parallel batch workloads, choosing the right serverless GPU provider directly impacts your iteration speed, production reliability, and total cost of ownership. This guide examines seven serverless GPU providers in 2026, starting with Modal, a code-first AI infrastructure platform that pairs SDKs and code-defined infrastructure in Python, TypeScript, and Go with an integrated product surface spanning inference, training, batch, sandboxes, and notebooks.

Serverless GPU infrastructure

Key Takeaways

1. Modal

Modal delivers high-performance serverless GPU infrastructure through a code-first approach that removes traditional DevOps complexity. The platform takes your code, puts it in a container, and executes it in the cloud. Container startup is engineered for fast cold starts through an optimized, content-addressed filesystem and multi-tier caching, and GPU Memory Snapshots reduce initialization work substantially for compatible workloads.

Core Capabilities

Product Portfolio

Modal offers purpose-built products for distinct AI workloads:

Security and Compliance

Modal has successfully completed a SOC 2 Type 2 audit. For HIPAA, Modal states plainly that there is no officially recognized HIPAA certification process, and Modal supports HIPAA-compliant workloads on Enterprise plans via a Business Associate Agreement. Audit logs and Okta SSO are available as enterprise features. Compute isolation uses gVisor-based sandboxing, all user data is encrypted in transit and at rest, and public Modal APIs use TLS 1.3. Best For: ML teams prioritizing developer experience, an integrated product surface across the AI lifecycle, and enterprise governance controls.

2. RunPod Serverless

RunPod provides serverless GPU infrastructure with a focus on broad hardware availability and flexible deployment options. RunPod announced in July 2026 that its platform had crossed one million developers. That figure is a platform-wide developer metric rather than a Serverless-specific count, and it is separate from the Community Cloud and Secure Cloud tiers, which describe RunPod's Pod and GPU Cloud infrastructure.

Key Features

Platform Deployment Options

Beyond Serverless, RunPod's broader GPU Cloud offers Community Cloud and Secure Cloud Pod deployment types, allowing teams to balance cost against consistency requirements. For Serverless specifically, the relevant controls are worker configuration, active versus flex worker counts, and endpoint scaling settings. Best For: Teams needing broad GPU variety and the flexibility to mix serverless workloads with dedicated instances on a single platform.

3. Vast.ai Serverless

Vast.ai operates a GPU marketplace model connecting users with compute providers worldwide. The company reported in March 2026 that monthly active paying customers had exceeded roughly 14,000; a separate May 2026 company article cited 120,000+ AI developers actively searching for compute, which is a different metric. Its Serverless launch documented 500+ locations, and the company reported in March 2026 that its marketplace had grown to nearly 20,000 GPUs across 5,000 machines from more than 1,000 independent hosts.

Key Features

Marketplace Considerations

The marketplace model means pricing and availability vary with host supply. This creates opportunities for cost savings alongside variability across hosts. Vast.ai documents production-use considerations, including reliability filtering and its Secure Cloud option. Best For: Cost-conscious teams with tolerance for marketplace variability who prioritize hardware selection breadth over managed platform consistency.

4. Beam Cloud

Beam Cloud delivers Python-native serverless GPU infrastructure with a focus on simplicity and competitive compute rates. The platform emphasizes deployment workflows and developer-friendly APIs.

Key Features

Developer Experience

Beam's Python-native approach reduces the learning curve for ML engineers already familiar with serverless patterns, and its scheduled jobs, volumes, and checkpoint-based startup optimizations cover the common deployment primitives for recurring GPU work. Best For: Python-focused teams seeking a balance between developer experience and compute costs, particularly for scheduled batch workloads.

5. Cerebrium AI

Cerebrium focuses on real-time AI workloads, with particular optimization for voice agents, video processing, and streaming applications. The platform emphasizes inference workloads and production reliability.

Key Features

Specialized Use Cases

Cerebrium's optimization for real-time streaming workloads makes it particularly suited for voice agents, video processing pipelines, and other latency-sensitive applications. Best For: Teams building real-time AI applications, particularly voice agents and streaming inference.

6. Koyeb

Koyeb provides a global serverless platform with GPU support, emphasizing scale-to-zero billing and multi-region deployment. The platform expanded GPU availability in January 2026 with reduced pricing across several SKUs.

Key Features

Platform Focus

Koyeb's strength lies in its developer-friendly deployment experience and global distribution. As of May 2026, Koyeb labels both scale-to-zero and volumes as public-preview functionality. Best For: Teams seeking a general-purpose serverless platform with GPU support and native GitHub integration for containerized workloads.

7. Nebius Serverless AI

Nebius offers enterprise AI cloud infrastructure with serverless capabilities, backed by its corporate history and a strategic partnership with NVIDIA. Nebius Group is the renamed former Dutch parent of Yandex following the divestiture of the Russian and certain other businesses. The platform includes interactive development environments alongside its serverless Jobs and Endpoints services.

Key Features

Development Focus

DevPods give Nebius an integrated interactive Jupyter and VS Code workflow alongside Jobs and Endpoints. Nebius described DevPods, Jobs, and Endpoints as its first steps toward container-based serverless compute, with endpoints running as persistent workloads and a current single-node scope. Best For: Enterprise teams seeking interactive GPU development environments alongside serverless deployment capabilities, particularly those requiring the latest NVIDIA hardware.

Why Modal Stands Out for Serverless GPU Workloads

Code-First Developer Experience

Modal's decorator-based API lets engineers define compute requirements directly in code without external configuration files, avoiding Dockerfiles, YAML configurations, and Kubernetes manifests for supported workloads. Modal ships SDKs and code-defined infrastructure in Python, TypeScript, and Go, and the code running on Modal is not limited to a single programming language. This code-first workflow can materially shorten deployment cycles. As one concrete example, OpenArt reported moving ComfyUI workflow deployments from hours to minutes and described development speed in its own workflow as roughly 5x to 10x faster. Those figures reflect that customer's own workflow.

Production-Grade Cold Start Performance

Cold start behavior separates predictable production APIs from unpredictable services. Modal is engineered for fast cold starts and faster feedback loops: a Rust-based container runtime with a content-addressed filesystem and multi-tier caching helps containers come online quickly without letting large images slow startup down. Container reuse and configurable warm pools, controlled by parameters such as scaledown_window, min_containers, and buffer_containers, keep frequently used functions ready to serve, and GPU Memory Snapshots cut initialization work for initialization-heavy inference workloads.

Comprehensive AI Workload Coverage

Modal provides purpose-built products spanning the AI development lifecycle:

Modal integrates inference, training, batch, Sandboxes, Notebooks, storage, queues, and key-value state in one code-first platform, which can reduce infrastructure integration work compared with assembling separate services for each workload type.

Enterprise Security and Compliance

Modal has completed a SOC 2 Type 2 audit. SOC 2 is an attestation and reporting framework rather than a legally mandated certification, but enterprise buyers commonly require a current report during procurement. For healthcare workloads, Modal notes that no officially recognized HIPAA certification process exists, and Modal supports HIPAA-compliant workloads on Enterprise plans via a BAA. Governance features including Audit logs and Okta SSO are available to enterprise customers. Modal's security architecture includes gVisor-based compute isolation, TLS 1.3 for public APIs, and encryption of all user data in transit and at rest.

Scalability Without Operational Burden

Modal handles capacity management by pooling capacity across major clouds and automatically scaling workloads to zero when inputs stop and scaling out across thousands of containers. Teams access B300, B200, H200, H100, A100, and other GPU types without reservations or minimum usage-time increments, and the same platform runs CPU and GPU workloads. Modal's AWS and Google Cloud Marketplace availability, announced in January 2026 for Enterprise customers, allows enterprises to apply existing committed cloud spend to Modal usage. Modal's Starter plan also includes $30 per month of free compute. For teams that prioritize developer velocity, an integrated product surface, and enterprise governance, Modal brings inference, training, batch, Sandboxes, and Notebooks together in a single code-first platform.

Frequently Asked Questions

  • Serverless GPU platforms reduce infrastructure management overhead, enabling teams to focus on model development rather than cluster operations. Common benefits include autoscaling, billing granularity that limits idle GPU-compute cost, and shorter deployment cycles. The degree of automation varies by provider: depending on the platform, serverless GPU services can automate resource provisioning, infrastructure lifecycle, driver and runtime management, health management, and failover. Service terms differ in how much of that scope they cover. Modal manages provisioning, container lifecycle, autoscaling, and scaling workloads to zero for both CPU and GPU workloads, so teams deploy from code rather than operating clusters.

  • Cold start performance varies across providers, and published numbers are only comparable when the measurement boundary is the same. Modal is engineered for fast cold starts and faster feedback loops, using an optimized, content-addressed filesystem and multi-tier caching so that large images do not slow startup down, with configurable warm pools and GPU Memory Snapshots reducing initialization work for compatible workloads. RunPod's FlashBoot maintains pre-warmed workers and supports cold starts. Beam supports cold starts and applies checkpoint-based startup optimizations, and Cerebrium supports cold starts alongside GPU-memory snapshot restoration. For latency-sensitive production APIs, consistent cold start performance matters more than best-case numbers, and startup is only one component of total request latency.

  • SOC 2 Type II reports are commonly requested in enterprise security reviews but are not universally mandated by law; SOC 2 is a voluntary attestation framework that enterprise customers often make a contractual procurement requirement. Modal, RunPod, Vast.ai, and Cerebrium all report SOC 2 Type II, with Cerebrium completing its Type II audit in July 2026. For healthcare applications, HIPAA obligations and business associate arrangements apply where a cloud provider handles ePHI, and vendor marketing language alone does not authorize a workload. Modal supports HIPAA-compliant workloads on Enterprise plans via a BAA. Additional considerations include encryption standards, compute isolation mechanisms such as gVisor sandboxing, and governance features like audit logs and SSO integration.

  • Yes, serverless GPU platforms support both training and inference workloads, though capabilities vary widely. Modal provides dedicated products for training, including multi-node GPU clusters with RDMA and InfiniBand, and inference with dynamic batching. RunPod's broader platform spans Pods, Serverless, and multi-node Clusters. Nebius combines broader AI Cloud infrastructure with Serverless Jobs and Endpoints, where Jobs launched as single-node workloads under its service terms. For training specifically, look for multi-node support, high-bandwidth networking between GPUs, and persistent storage for checkpoints. Inference workloads prioritize cold start performance and autoscaling capabilities.

  • Marketplace providers such as Vast.ai can offer lower prices through supply-driven competition, where comparable hardware is often cheaper, although rates, availability, and host characteristics vary. Managed platforms such as Modal instead pool capacity across major clouds and provide integrated developer tooling, autoscaling, and enterprise governance controls, with pricing published on a per-second basis without reservations rather than set by host supply. Marketplace infrastructure can suit experimentation, batch, and production workloads alike, and managed platforms concentrate on consistent performance, integrated tooling, and governance for production teams. The right choice depends on workload requirements rather than a fixed rule about which category belongs in production.
