Modal runs containers up to 100x faster than Docker, giving AI teams serverless compute for inference, training, and batch jobs without managing servers. It automatically scales from zero to hundreds of GPUs across multiple clouds, targeting ML teams that need infrastructure to expand and shrink with demand rather than staying provisioned around the clock.
About Modal
Modal Labs, founded in 2021, raised a $111M Series B in July 2025. The company built a serverless compute platform purpose-built for AI, ML, and data teams: developers run compute-intensive workloads without managing infrastructure, with sub-second container cold starts, instant autoscaling, and a developer experience that feels local. Define everything in code using Python decorators (no YAML, no Dockerfiles) and Modal handles containerization, resource allocation, scaling, and orchestration automatically.
The platform is engineered from the ground up for heavy AI workloads, with multi-cloud GPU capacity, globally distributed storage, and integrated observability. Whether deploying LLM inference at scale, fine-tuning models on multi-node clusters, running massive batch jobs, or executing untrusted code in sandboxes, Modal abstracts away operational complexity so teams can focus on model development rather than infrastructure management.
Pricing
Free Starter tier with $30/month in compute credits. Team plan at $250/month (includes $100/month in credits, unlimited seats, 1000 containers, 50 GPU concurrency). Enterprise plan with custom pricing for volume-based discounts and higher concurrency.
001097/sec (H100). Multipliers apply for regional selection and non-preemptible sandboxes.
| Tier | Monthly price | What it includes |
|---|---|---|
| Starter | Free | Per-second CPU/GPU/Memory usage with $30/month free credits; 100 containers max, 10 GPU concurrency |

| Team | $250/mo | Per-second CPU/GPU/Memory usage with $100/month in credits on top of $250/month subscription; 1000 containers, 50 GPU concurrency, unlimited seats |
Key Features
- Sub-second Cold Starts: Spin up GPU-enabled containers in as little as one second with custom infrastructure optimized for rapid iteration and scaling, eliminating cold start latency that plagues traditional serverless platforms.
- Elastic GPU Scaling: Autoscale from zero to hundreds of GPUs on-demand based on workload, with deep multi-cloud capacity and intelligent scheduling that ensures access to CPUs and GPUs without managing quotas or reservations.
- Python-First Infrastructure: Define entire environments, hardware requirements, and deployment logic in pure Python using simple decorators (@app.function, @app.cls) without YAML files or complex configuration, keeping environment and hardware requirements in sync.
- Unified Observability: Integrated logging and full visibility into every function, container, and workload with built-in dashboards, real-time logs, and first-party integrations with Datadog and OpenTelemetry for monitoring and debugging.
- Multi-workload Support: Deploy inference for LLMs and generative models, fine-tune open-source models, run large-scale batch jobs, execute untrusted code in sandboxes, and collaborate in real-time with shareable notebooks, all from a unified platform.
- Memory Snapshots: Dramatically reduce cold start latency (up to 10x) by capturing container state after initialization and restoring it for subsequent starts, enabling GPU snapshots for even faster LLM deployments.
Pros
- Exceptional developer experience with Python decorators, minimal boilerplate, and local-like iteration loops in the cloud
- Cold starts are quick enough that GPU functions behave like ordinary local code instead of waiting through a container boot, which matters most for interactive inference
- Flexible usage-based pricing without per-request charges, scaling from zero to thousands of GPUs on-demand
- Genuinely serverless: no infrastructure management, no Kubernetes, no container orchestration to maintain
- Deep multi-cloud capacity with intelligent scheduling ensuring GPU access without managing quotas or reservations
Cons
- Python-first platform limits flexibility for polyglot teams or non-Python workloads
- Vendor lock-in due to managed-only deployment model (no Bring Your Own Cloud option)
- Less granular control over underlying infrastructure compared to traditional cloud providers like AWS/GCP
- Regional limitations for latency-sensitive inference (primarily Ashburn, Virginia for HTTP traffic)
Data Handling
- Compliance
- SOC 2 · HIPAA · Okta SSO · audit logs · data residency controls
Frequently Asked Questions
What does Modal actually cost?
Modal has three tiers: Starter is free, Team costs $250 a month, and Enterprise is custom-priced with volume discounts. Beyond the included credits, usage is billed per second for CPU, memory, and GPU time, with extra multipliers applied for regional selection or non-preemptible sandboxes.
What do you get on Modal's free tier?
Modal's free Starter tier includes $30 a month in compute credits, capped at 10 concurrent GPU workers. It does not include the Team plan's unlimited seats or 50-GPU concurrency, and any usage beyond the included credits bills at the same per-second rates as the paid tiers.
Which tools compete with Modal in 2026?
Replicate is the simpler choice for calling a pre-packaged open-source model through an API rather than writing custom deployment code. Together AI offers a managed catalog of open-source models to fine-tune without building a container pipeline from scratch. Fireworks AI is worth a look when the need is pay-per-token LLM inference rather than general-purpose Python compute.
Modal or AWS Lambda: which should you pick?
Modal is purpose-built for ML workloads, offering direct GPU access and support for long-running jobs that Lambda cannot handle. AWS Lambda caps out at a 15-minute timeout and a 50MB deployment package, making it a fit for short, event-driven glue code rather than model inference or training. Choose Modal for AI workloads and Lambda for lightweight application backends.
How long does it take to get going with Modal?
A first deployment usually takes minutes: install the Python client and wrap any existing Python function with the @app.function decorator instead of writing a Dockerfile or YAML config, and Modal handles containerization and scaling automatically. New accounts default to the free Starter tier, so early deployments cost nothing until the included credits run out. The official Getting Started guide at modal.com/docs/guide walks through that first deployment step by step.
Top Alternatives
- Replicate: Replicate covers calling a pre-packaged open-source model over an API and nothing more. Modal is built for the opposite case: running and scaling custom Python code you wrote yourself.
- Together AI: Together AI works from a managed catalog of ready-to-fine-tune open-source models. Modal has no catalog at all, built instead for custom Python code and container logic that goes beyond any fixed model list.
- Fireworks AI: Fireworks AI is scoped to pay-per-token LLM inference alone. Modal covers more ground: training, batch jobs, and sandboxes, all billed per second instead of per token.
- Groq: Groq's LPU hardware delivers low-latency inference, but only across a fixed model lineup. Modal runs general-purpose GPU compute instead, covering training, fine-tuning, and custom inference code Groq's fixed lineup can't touch.
