Por qué es importante la especificidad

El problema de la vaguedad

Prompt vago: escriba sobre perros

import anthropic

client = anthropic.Anthropic(api_key='sk-ant-your-key-here')

vague = 'Write something about dogs.'
specific = (
    'Write a 200-word Instagram caption for a golden retriever puppy\'s '
    'first day at the beach. Tone: playful and emotional. '
    'End with 5 relevant hashtags.'
)

for label, prompt in [('VAGUE', vague), ('SPECIFIC', specific)]:
    response = client.messages.create(
        model='claude-opus-4-5',
        max_tokens=300,
        messages=[{'role': 'user', 'content': prompt}]
    )
    print(f'--- {label} ---')
    print(response.content[0].text)
    print()

Por qué se producen respuestas genéricas

# Default (vague) output
default_response = client.chat.completions.create(
    model='gpt-4o',

)
print('DEFAULT OUTPUT (first 200 chars):')
print(default_response.choices[0].message.content[:200])
print()

# Constrained output
constrained_response = client.chat.completions.create(
    model='gpt-4o',
    messages=[{
        'role': 'user',
        'content': (
