Union.ai

Union.ai enables AI development teams to rapidly ship high-quality code to production by offering optimized performance, unparalleled resource efficiency, and a delightful workflow authoring experience. With Union.ai your team can:

  • Run complex AI workloads with performance, scale, and efficiency.
  • Achieve millisecond-level execution times with reusable containers.
  • Scale out to multiple regions, clusters, and clouds as needed for resource availability, scale, or compliance.

Union.ai is built on top of the leading open-source workflow orchestrator, Flyte.

Union.ai provides all the features of Flyte, plus much more, in an environment where you keep your data and workflow code on your own infrastructure. Union.ai is available as BYOC (Bring Your Own Cloud), where Union.ai manages the infrastructure for you, or Self-managed, where you manage the data plane yourself.

These are the Union.ai 2.0 docs. To switch to version 1.0 or to another product variant, use the selectors above.

Basics

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

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. Agents Durable, self-healing agents built from tasks and apps, with sandboxing and MCP.

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.
