Unit 4 · Connect AI steps into a workflow

Build a workflow with explicit steps

You define application-owned state and a visible sequence of typed nodes. Input mappings feed each node, and the return mapping selects the final result.

See the idea in context

step = ax('request:string -> route:class "support, sales, engineering"')
program = (
    flow({"id": "supportRouter"})
    .execute("classify", step)
    .returns({"route": "classify"})
)

Declare a typed node
draft states exactly what the AI step receives and returns.
Map state into the node
execute() passes the workflow topic into the draft program.
Choose the public result
returns() exposes only the final text to the caller.

Run itIn your own project

pip install axllm

from axllm import ai, ax

llm = ai('openai', api_key=os.environ['OPENAI_API_KEY'])
classify = ax('review:string -> sentiment:class "positive, negative, neutral"')

Set OPENAI_APIKEY in your environment before running provider-backed code.
