Unit example (nearest native match)

See the idea in context

from axllm import ax

answer = ax('question:string -> answer:string')

Create the program
The signature asks for an answer and a numeric confidence.
Pass a provider and input
forward() runs the program with llm and the required question.
Use the typed result
result exposes the declared output fields instead of raw model text.

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.
