AI teams face a growing challenge: how to access powerful GPUs globally without the operational and financial burden of managing infrastructure. Provisioning GPU resources on AWS, GCP, or Azure is often slow and expensive - idle instances waste money, scaling takes minutes not seconds, and access to in-demand chips like H100s or H200s requires costly long-term reservations. And when your application goes viral, scaling quickly across regions can be nearly impossible.

On top of that, many organizations must comply with strict data residency requirements. Sensitive data — such as healthcare records, financial information, or user conversations - often needs to be processed and stored within specific geographic regions. Setting up and maintaining multi-region GPU infrastructure that meets these compliance standards adds even more operational complexity.

Serverless GPU compute solves these problems by offering on-demand access to GPUs without the need to manage clusters, nodes, or scaling policies. You deploy your model or workload, and the platform automatically handles container orchestration, scaling, load balancing, and fault tolerance — all while charging only for actual compute time, often billed per second. Under the hood, modern serverless GPU platforms source capacity from multiple providers and regions to overcome GPU shortages and deliver global coverage while ensuring data stays within compliant boundaries.

For workloads that don’t require GPU acceleration, the same serverless model extends to CPU-based compute - essential for data preprocessing, ETL pipelines, or inference routing. These large CPU nodes are also scarce and expensive to manage manually, making the abstraction just as valuable across both compute types.

The Core Problem: Volatile, Unpredictable Workloads

This is the biggest reason teams move to serverless GPUs. Most AI workloads - whether inference, training, or experimentation - are inherently bursty and unpredictable:

• Inference requests spike during business hours and drop to near-zero overnight

• Training runs occur sporadically - short bursts of high GPU utilization followed by idle periods

• Experimentation leads to frequent starts, stops, and configuration changes

• Global traffic patterns and seasonal events cause large swings in demand across regions

Traditional infrastructure forces you to provision for peak load, meaning you pay for idle GPUs during low-traffic periods. Scaling up takes time, and scaling down still leaves you over-provisioned.

To make matters worse, sourcing GPU capacity itself has become a major challenge. High-demand chips like H100s or H200s often require long-term reservations or are limited to specific regions. Relying on a single cloud provider makes it difficult - sometimes impossible - to acquire the required capacity when demand spikes.

Serverless GPU platforms eliminate this friction. They scale automatically from zero to hundreds of GPUs based on real-time demand and draw from multiple cloud and hardware providers under the hood. This ensures availability, performance, and cost-efficiency - without the need for teams to worry about reservations, capacity planning, or multi-region scaling.

What Workloads Serverless Compute Works Best For

Serverless GPU compute isn’t a silver bullet for every type of workload - but for the majority of modern AI applications, it’s an ideal fit. The key factor is variability: if your workload doesn’t require GPUs to be running 24/7, or scales dynamically based on user or model activity, serverless architecture gives you the flexibility and efficiency you need.

1.Model Inference & APIs

Inference workloads are naturally spiky. User requests fluctuate throughout the day and can change dramatically with traffic patterns or viral growth. Serverless GPUs shine here — they scale instantly based on demand and scale back to zero when idle, eliminating the cost of idle compute. This is especially powerful for startups or global products serving users in multiple time zones.

2.Batch & Scheduled Jobs

Data processing pipelines, video/audio transcription, and periodic fine-tuning jobs don’t need constant compute. With serverless, these tasks can run at massive parallelism when triggered, then release all resources when complete — ideal for high-throughput, short-lived workloads.

3.Training & Experimentation

Model training is often iterative and unpredictable. Teams frequently start, stop, and modify runs as they experiment with architectures or hyperparameters. Serverless GPUs allow you to spin up training environments instantly, run an experiment, and tear it down automatically — perfect for fast-paced R&D environments or automated sweeps.

4.Event-Driven or Real-Time Applications

Voice agents, generative chatbots, or live video applications demand compute that responds in real time — often with low latency and dynamic scaling. Serverless GPU platforms handle these bursts seamlessly, spinning up containers within seconds while maintaining consistent performance across global regions.

5. Hybrid Workloads (GPU + CPU)

Many AI applications combine GPU inference with CPU-heavy preprocessing (e.g., feature extraction, data normalization, or routing). Serverless platforms that offer both GPU and CPU compute let teams run entire pipelines on-demand without managing separate clusters or environments.

What to Look For in a Serverless GPU Platform

Cold Start Performance

Cold starts are one of the most important factors when evaluating a serverless GPU platform. They determine how quickly your application becomes responsive when scaling from zero or handling new workloads.

There are two key components:

• Container Cold Starts: How quickly the platform can spin up containers and load your environment - including your Python runtime, dependencies, and image layers.

• Application Startup Time: How fast your models load and imports initialize once the container is active.

Leading serverless GPU platforms achieve 1–4 second container cold starts. To further reduce startup time, look for platforms that offer memory and GPU checkpointing, which restores the application’s state directly from memory instead of reloading models from scratch - resulting in significantly faster readiness after scale events.

It’s also important to evaluate these metrics at scale, not just for a few instances. Some platforms maintain low startup times when scaling from 0→5 containers but degrade substantially when scaling from 0→200. Consistent performance under large-scale concurrency is what truly differentiates a mature serverless platform.

Compute Variety and Workload Flexibility

As organizations expand their use of AI, they’re running an increasingly diverse mix of workloads - from large language models and voice agents to data processing, audio, and multimodal applications. Each of these workloads has unique compute requirements in terms of latency, throughput, memory, and cost efficiency.

A strong serverless GPU platform should provide a wide range of compute types to match those needs. Low-latency inference may require high-end GPUs like NVIDIA H100s or H200, while cost-efficient batch jobs might run better on L4’s or AMD Instinct GPUs. Data-heavy preprocessing workloads often perform best on large CPU instances, and some teams may benefit from access to specialized accelerators such as TPUs, AWS Inferentia, or Trainium.

Choosing the right compute for the right task can dramatically reduce costs and improve performance. Look for platforms that not only offer variety but also make it easy to select or dynamically assign compute based on your workload’s specific constraints - whether it’s latency, speed, batching, or cost optimization.

Multi-Region Deployment and Global Compliance

As companies scale globally and serve clients in various markets, compliance and latency become critical. Regulations like GDPR (Europe), HIPAA (U.S.), and emerging data protection laws in India and other countries require data to stay within specific regions.

Modern serverless GPU platforms address this by offering dedicated deployment regions across North America, Europe, the U.K., India and many more ensuring workloads meet local residency and privacy requirements while maintaining low-latency performance.

Multi-region deployment isn’t just about compliance - it’s also about speed. Routing inference requests to the nearest GPU region can reduce latency by hundreds of milliseconds, delivering noticeably faster performance for real-time AI workloads such as voice agents and interactive chatbots.

Security and Compliance: Enterprise Requirements for AI Infrastructure

Companies expect their serverless GPU platform to meet the same security and compliance standards their customers demand of them. This includes industry-recognized certifications and frameworks that guarantee data protection and regulatory alignment.

SOC 2 Type II: Confirms that the platform maintains strong operational and security controls around data protection, availability, and confidentiality - essential for enterprise AI workloads in the United States.

GDPR Compliance: Ensures that European user data is processed and stored in accordance with EU privacy regulations, including consent management, deletion rights, and cross-border data safeguards.

HIPAA Compliance: Required for healthcare applications handling PHI, covering encryption, access management, audit logging, and signed Business Associate Agreements (BAAs).

As you serve, larger enterprise cusomters, they start to expect standards beyond certifications, companies expect platforms to offer end-to-end encryption, role-based access control (RBAC), private networking options like VPC or PrivateLink, and comprehensive audit trails.

Pricing

Serverless GPU platforms are typically priced on usage-based billing, measured per second or minute of active compute time. You only pay when your workload is running.

However, it’s important to understand that usage refers to compute time, not just inference time. For example, if it takes 30 seconds for your model to load into VRAM before serving any requests, you’re still billed for that period - since GPU compute is being consumed during initialization. This is why memory and GPU checkpointing are so valuable: beyond delivering faster responsiveness, they restore your model state instantly and significantly reduce billable startup time.

Many platforms still charge for entire GPU instances, bundling fixed CPU and memory allocations with each GPU (e.g., a 1×H100 with 24 vCPUs and 124 GB of RAM). Since most workloads don’t fully utilize those resources, this leads to unnecessary waste and higher costs.

More advanced platforms offer granular pricing, charging separately for GPU, CPU, and memory utilization. This lets you right-size your environment based on actual workload requirements — achieving better cost efficiency and transparency while maintaining high performance.

Head-to-Head Comparison of Top Providers

As more teams adopt serverless GPU infrastructure, the ecosystem has matured with several competing platforms. Each offers trade-offs in cold start latency, pricing models, GPU variety, and compliance coverage. The table below provides a snapshot comparison of leading providers.

Cold-Start Latency

Cerebrium and Beam lead in cold start performance, both achieving 2–4 second startup times, while RunPod and Google Cloud Run fall in the mid-range, and Baseten trails with 16–60 second startup delays.

GPU Variety

In terms of hardware variety, RunPod offers the widest selection with 11 GPU types, closely followed by Cerebrium at 10, while Baseten and Beam provide fewer options.

Security and Compliance

Compliance coverage varies considerably. Cerebrium supports HIPAA, SOC 2, and GDPR, matching enterprise-level requirements, while RunPod and Google Cloud Run offer similar frameworks, though Baseten’s compliance list is narrower but does come with a self-hosted option.

Multi-Region Deployment and Global Compliance

Google Cloud Run provides the broadest global reach with 20 regions, whereas Cerebrium offers a balanced footprint across 5 key regions optimized for data residency and latency. Beam and Baseten remain limited to a single region, making them less suitable for globally distributed workloads.

Pricing Model

Cerebrium and Beam also stand out for their granular per-second pricing, allowing customers to pay only for the GPU, CPU, and memory actually consumed — unlike Baseten, which bills per minute, or RunPod, which allocates entire nodes for each request, while platforms like Cerebrium charge for exactly the resources consumed.

Real-World Cost Analysis: Running GPT-OSS-120b

To understand the real cost impact of serverless GPU infrastructure, let’s look at a practical example - running a large language model workload on both traditional cloud infrastructure and serverless GPU platforms.

In this analysis, we’ll benchmark GPT-OSS-120B using the vLLM framework for a throughput-intensive workload. The workload parameters are as follows:

• Average input prompt size: 5,000 tokens

• Average output tokens generated: 1,780 tokens

• Target throughput: 12 million tokens per minute

For this test, we needed a H100 GPU with a 2-GPU configuration and it never needed more than 40 vCPUs and 200 GB memory. Based on internal benchmarks, achieving the desired throughput requires approximately 21 instances, each using 2×H100 GPUs.

Note: Google cloud run doesn’t support H100’s and so they were not included.

Let us see what this would cost across different providers per minute:

The cost comparison shows significant differences in both pricing models and operational flexibility across serverless GPU providers. Runpod offers the lowest rate with Cerebrium in close second. However, Cerebrium offers the per-second, granular billing across GPU, CPU, and memory resources allowing teams to pay only for the compute they actually use, avoiding the resource waste common with fixed instance bundles.

RunPod and AWS charge flat rates per GPU instance ($0.09 and $0.131 per minute, respectively), which can lead to inefficiencies when workloads don’t fully utilize bundled CPU or memory. Baseten and Beam are the most expensive option ($0.2166 per minute and $0.2476 per second) making it less suitable for volatile or bursty inference workloads that frequently scale up and down.

It’s also worth noting that AWS requires capacity reservations for H100 clusters (typically 8 GPUs or more), which limits elasticity - meaning if your workload suddenly spikes (e.g., a product goes viral), you may not be able to provision additional capacity in time.

The Bottom Line

As AI adoption accelerates, teams are realizing that building great models is only half the challenge - running them efficiently, securely, and globally is the other. Traditional cloud infrastructure struggles to keep up with volatile workloads, strict data residency requirements, and the growing diversity of AI applications. Serverless GPU platforms solve this by abstracting away the complexity of provisioning, scaling, and managing compute - giving teams instant access to powerful GPUs anywhere in the world, without the cost of idle resources or operational overhead.

The best platforms combine fast cold starts, multi-region compliance, broad compute variety, and transparent per-second pricing to meet modern AI demands. With support for features like GPU and memory checkpointing, they not only improve performance but also reduce costs by eliminating wasted compute time. For organizations scaling AI across multiple products or regions, serverless GPU infrastructure isn’t just a convenience - it’s becoming a foundational layer for running production AI at global scale.
