Examples

Every example here lives in the Flux source tree under examples/. Each page renders the current source verbatim, plus a one-line context note and the command to run it. If the source changes upstream, the page changes with the next regen.

Top-level examples

Twenty-one single-file examples cover the core surface — one feature each, kept small enough to read in a sitting. Start with these if you are new to Flux:

• Hello World — the smallest workflow you can write
• Simple pipeline — tasks chained in sequence
• Parallel tasks — fan out with parallel(...)
• Subflows — workflows calling other workflows
• Pause — pause and resume with operator input
• GitHub stars — a real HTTP call, retried and cached
• Scheduled workflow — cron-driven runs
• Using secrets — pull credentials at task time
• Output storage — offload large outputs to disk or S3
• Determinism — what the replay engine guarantees

The full set also covers cancellation, sleep, graph composition, task progress, resource requests, dataframe-with-pause, multiple pause points, and a couple of AI samples. Browse the sidebar for the complete list.

Full pipelines

Longer tutorials that build production-shaped systems end-to-end. Each one walks through five to eight stages with prose explaining why the boundaries fall where they do.

• End-to-end RAG application — extract, embed, store, retrieve, generate
• Document processing pipeline — OCR, structured extraction, classification, indexing
• Customer support automation — email ingest, triage, draft, human approval, send

AI agent examples

Flux ships dozens of AI agent examples under examples/ai/ in the source repository — conversational agents, tool use, planning, RAG, streaming, sub-agents, and more. Each script is its own page in the AI / Agents sub-group; browse the sidebar for the full set. For the canonical recipes, read Agents → Patterns.
