What it is
Flyte is an orchestration engine designed to reliably manage ML pipelines, models, and agents at scale, primarily via a Python-focused user experience, with a Go-based backend. The repository has ongoing development and multiple releases in 2026, indicating active maintenance.
How it works
The project coordinates tasks, environments, and workflows to run end-to-end AI pipelines. The README includes Python code examples showing task definitions, environment configuration, and a simple local execution flow using flyte.init() and run(). It also demonstrates serving a model via a FastAPI app wrapped in Flyte's app environment. Local development features include a TUI and a DevBox option for running locally.
Getting started
Install Flyte with:
uv pip install flyte
For full SDK and development tools, see the flyte-sdk repository. Local development experience can be enhanced by installing the TUI via:
uv pip install flyte[tui]
See links in the README for run-modes and getting started with DevBox.
