DSPy: see a signature produce the author’s haiku
Build the first haiku program from the author’s complete LM setup and signature example. The printed poem is the tutorial’s illustrative output; its exact generation model is unspecified. The copied recipe preserves the setup model string and API-key placeholder.
Input di esempio
import dspy
# Pass the key explicitly...
lm = dspy.LM("openai/gpt-5-nano", api_key="YOUR_OPENAI_API_KEY")
dspy.configure(lm=lm)
haiku_signature = "subject -> haiku"
haiku_generator = dspy.Predict(haiku_signature)
result = haiku_generator(subject="computer science")
print(result.haiku)Risultato di esempio

Source-authored examples are separate from site-reproduced results; no original scripts, installations, model/API requests, account creation, memory writes, graph queries or tests were executed. Complete pinned source blocks are assembled in documented order, with their separate file bindings retained in the review record. The SDK setup and printed illustrative poem come from separate source sections; no exact generation-model binding is claimed.

DSPy: specify setting, mood and season
The full source signature adds setting, mood and a Literal season before calling the haiku program for Bodega Bay. The author’s printed poem stays alongside the recipe. Setup and sample output come from separate documented sections, so the poem’s exact model is unspecified.
Input di esempio
import dspy
# Pass the key explicitly...
lm = dspy.LM("openai/gpt-5-nano", api_key="YOUR_OPENAI_API_KEY")
dspy.configure(lm=lm)
from typing import Literal
Season = Literal[
"spring", "summer", "autumn", "winter",
]
class HaikuBot(dspy.Signature):
"""
Write a classical haiku given the provided inputs.
"""
location: str = dspy.InputField()
mood: str = dspy.InputField()
season: Season = dspy.InputField()
haiku: str = dspy.OutputField()
haiku_bot = dspy.Predict(HaikuBot)
result = haiku_bot(location="Bodega Bay", mood="mysterious", season="autumn")
print(result.haiku)Risultato di esempio
Fog drifts over waves,
Crimson leaves swirl by the pier—
Night whispers secrets.Licenza
