Modal (modal-com)

Modal is a serverless cloud platform for AI and data workloads. Developers write ordinary Python and run it on remote GPUs and CPUs with sub-second cold starts, instant autoscaling, and declarative container images. Modal's primitives — Functions, Sandboxes, Volumes, Images, Secrets, Dicts, Queues, Schedules, and Web Endpoints — cover inference, fine-tuning, multi-node training, batch processing, agent code execution, and HTTP/web APIs.

APIs

Modal Functions API

Serverless Python functions backed by autoscaling container pools. Optional GPU attachment, declarative images, Volumes, Secrets, retries, timeouts, scheduling, dynamic batching, and class-based stateful workers. Invoke synchronously (.remote()), asynchronously (.spawn()), or as a map (.map()).

• Naftiko Capability — Functions

Modal Sandboxes API

Secure containers for executing untrusted user or agent code. Sandbox.create() returns a long-lived isolated environment with exec, filesystem snapshots, port tunnels, volume mounts, GPU attachment, idle timeouts up to 24 h, readiness probes, named lookup, and tag-based filtering. The workhorse primitive for LLM coding agents on Modal.

• Naftiko Capability — Sandboxes

Modal Volumes API

High-performance distributed file system optimized for ML workflows. Volume.from_name() attaches to Functions and Sandboxes with concurrent-read support, explicit commit() and reload() semantics, sub-path mounting, and read-only mounts. Volumes v2 (beta) removes inode limits and supports hundreds of concurrent writers to distinct files.

• Naftiko Capability — Volumes

Modal Images API

Declarative, layered container image specifications built lazily on Modal's backend. Build from debian_slim, micromamba, from_registry, or from_dockerfile; layer pip_install, apt_install, run_commands, env, copy_local_file, and copy_local_dir. Modal caches layers globally so cold starts of identical images are sub-second.

• OpenAPI
• Naftiko Capability — Images

Modal Secrets API

Encrypted, named bundles of environment variables injected into Functions and Sandboxes at runtime. Manage via dashboard, the modal secret CLI, or programmatically with Secret.from_name() / Secret.from_dict().

Human URL: https://modal.com/docs/guide/secrets

• OpenAPI
• Naftiko Capability — Secrets

Modal Dicts and Queues API

Distributed in-memory primitives. modal.Dict is a named key-value store; modal.Queue is a FIFO queue with optional partitioning and blocking gets. Both are addressable by name across Functions and Sandboxes for cross-container coordination.

Human URL: https://modal.com/docs/guide/dicts

• OpenAPI
• Naftiko Capability — Dicts and Queues

Modal Schedules API

Periodic execution attached to a Function via @app.function(schedule=modal.Cron(...)) or modal.Period(...). Cron supports full cron syntax with timezone; Period specifies a fixed interval. Past runs appear in the dashboard with manual "run now" support.

• OpenAPI
• Naftiko Capability — Schedules

Modal Web Endpoints API

Expose Functions over HTTP via @modal.fastapi_endpoint, @modal.asgi_app (FastAPI / Starlette / FastHTML), @modal.wsgi_app (Flask / Django), or @modal.web_server (any port-binding server). Supports streaming, WebSockets, proxy-auth tokens, custom URL labels, and live development via modal serve.

• OpenAPI
• Naftiko Capability — Web Endpoints

Modal Tokens and Administration API

Token id/secret pair creation and revocation, environment management (e.g. dev/staging/prod), and workspace metadata. Tokens authenticate the modal CLI and the Python/TypeScript/Go SDKs against the control plane at api.modal.com.
