Управление длиной ответа

AI so powerful
Computers

Что такое токены

Токены: единицы текста, которые помогают ИИ понимать и интерпретировать текст

Предложение «How can the OpenAI API deliver business value?», в котором каждый токен выделен отдельным цветом.

Расчёт стоимости

Стоимость зависит от модели и количества токенов 💰
- Модели тарифицируются по принципу стоимость/токены
- Входные и выходные токены могут стоить по-разному
Увеличение max_completion_tokens повышает стоимость 📈

Расчёт стоимости

prompt = f"""Summarize the customer support chat 
             in three concise key points: {text}"""

max_completion_tokens = 500

response = client.chat.completions.create(
  model="gpt-4o-mini",
  messages=[{"role": "user", "content": prompt}], 
  max_completion_tokens=max_completion_tokens
  )

Расчёт стоимости

# Define price per token
input_token_price = 0.15 / 1_000_000
output_token_price = 0.6 / 1_000_000

# Extract token usage
input_tokens = response.usage.prompt_tokens

output_tokens = max_completion_tokens

# Calculate cost
cost = (input_tokens * input_token_price + output_tokens * output_token_price)
print(f"Estimated cost: ${cost}")

Estimated cost: $0.00124
