Everything you need to build, run, and operate workloads on Flyte, from first task to production deployment.

Union.ai

Union.ai is the durable AI runtime your team owns. Your workloads run in your own cloud, and your data and code never leave it: they never traverse the Union.ai control plane. On it, you build model factories, production agents, and model serving in plain Python, as durable steps that can recover from failure.

Union.ai is enterprise-grade Flyte, open source at the core. See Platform deployment for the ways to run it.

Basics

Learn the basics of Flyte, covering all the core concepts around tasks, apps, agents, and typed model calls.

Get started What Flyte 2 is, how to install it, the core concepts, and the ways to run your code. Tasks Configure, build, and deploy the durable batch workloads that everything else is made of. Apps Long-running services for dashboards, REST APIs, and model endpoints. Triggers Run tasks automatically on a schedule or in reaction to new data, or save named launch configurations to fire on demand. Agents Durable, self-healing agents built from tasks and apps, with sandboxing and MCP. System one types Answer many typed questions in one call, with calibrated confidence, and decide what happens next in code.

Artifacts and factories

Name and version the datasets and models your tasks produce, trace where they came from, and build them on demand with factories.

Artifacts Register task outputs and uploads as named, versioned artifacts, trigger runs on new versions, mount them into apps, and trace lineage. Factories Declare how artifacts are made from other artifacts, then ask for any artifact for a partition or a range and let Union build only what is missing or stale.

Access and identity

How to authenticate and manage user permissions on your Union cluster.

Authenticating Authenticate with Union.ai using OAuth2, API keys, and service accounts. User management Manage users, roles, and policies for your Union cluster.

Cluster and workload management

Stand up clusters and govern where your workloads run.

Clusters and queues Group clusters into pools, register clusters, and create queues that route and rate-limit your workloads.

Advanced guides

Organize your codebase, optimize performance for production, and migrate from other workflow orchestrators.

Project patterns Patterns for BYO images, monorepos with uv, CI/CD, and multi-team resource management. Run scaling Tune task overhead, batching, reusable containers, and fanout to scale your workflows. Advanced project An advanced guide for building an LLM reporting agent on Flyte. Migration Port a Flyte 1 codebase to Flyte 2, or map Airflow concepts to their Flyte 2 equivalents.
