About
Flyte is a production-grade, open-source orchestration platform designed for AI, machine learning, and data engineering workflows. With over 80 million downloads, it has become a trusted foundation for teams that need reliable, scalable execution of complex computational pipelines. Flyte excels at running durable AI agents with full observability, enabling teams to build autonomous workflows powered by LLMs and tools like OpenAI Agents. It natively supports high-throughput generative AI inference tasks — including Stable Diffusion image generation — by managing GPU resources, containerized environments, and secrets out of the box. The platform also handles large-scale data ETL jobs using modern frameworks like DuckDB and Pandas, making it equally valuable for data engineering teams. Flyte's task environment system allows developers to declaratively define compute resources, Docker images, pip packages, and secrets per task, ensuring reproducibility and isolation. Flyte 2 offers local execution for rapid iteration, while Flyte 1 supports distributed execution at scale. For enterprise teams, Union.ai provides a hosted platform built on top of Flyte. Flyte integrates with a rich ecosystem including OpenAI, Hugging Face, Spark, and more. It is the platform of choice for ML engineers, data scientists, and platform teams building robust AI systems that need to run reliably in production.
Key Features

- Generative AI Inference at Scale: Supports high-throughput inference for models like Stable Diffusion, with GPU resource management, containerized environments, and automated reporting.
- Data ETL Pipeline Orchestration: Orchestrate large-scale data transformation jobs using modern frameworks like DuckDB, Pandas, and Spark with declarative task definitions.
- Declarative Task Environments: Define compute resources, Docker images, pip packages, and secrets per task, ensuring full reproducibility and environment isolation.
- Local and Distributed Execution: Flyte 2 supports rapid local iteration, while Flyte 1 enables distributed execution at scale, with an enterprise-hosted option via Union.ai.
Use Cases
- ML engineering teams building and scheduling end-to-end model training and evaluation pipelines
- AI teams deploying durable LLM-powered agents with external tool integrations
- Data engineers orchestrating large-scale ETL jobs using DuckDB, Pandas, or Spark
- Generative AI teams running high-throughput image or text generation workloads on GPU infrastructure
- Platform teams providing a standardized, observable workflow execution environment for multiple internal teams
Pros
- Production-Proven at Scale: With 80M+ downloads and enterprise adoption, Flyte is battle-tested for running critical AI and data workflows in production.
- Rich Ecosystem Integrations: Integrates with OpenAI, Hugging Face, DuckDB, Spark, and many other tools, making it adaptable to diverse AI and data stacks.
- Full Observability: Built-in observability features provide visibility into task execution, resource usage, and workflow state for easier debugging and monitoring.
Cons
- Steep Learning Curve: Flyte's declarative model and infrastructure concepts can be complex for teams without prior workflow orchestration experience.
- Self-Hosting Overhead: Running Flyte at scale in a distributed setting requires Kubernetes expertise and infrastructure management unless using the hosted Union.ai platform.
Frequently Asked Questions
What is Flyte used for?
