Contador de Tokens LLM y Calculadora de Costes de API
Esta herramienta funciona 100% del lado del cliente en su navegador. Su código, tokens, claves API y datos confidenciales nunca se envían a servidores externos, garantizando privacidad absoluta.
Fórmula y Método de Cálculo
Costo de API = (Tokens de prompt × Tarifa de entrada) + (Tokens de finalización × Tarifa de salida)
LLM providers charge drastically different rates for 'Input' (reading the prompt) versus 'Output' (generating the response). Output tokens are almost always significantly more expensive.
Mejores Prácticas y Consejos
- Pre Tokenize Massive Datasets: If you are feeding a 50 page PDF into a model, always run it through a token counter first. If the token count exceeds the model's Context Window (e.g., 128K for GPT4), the API call will crash.
- Optimize Prompt Verbosity: Because you pay per token, remove unnecessary pleasantries (like 'Please' or 'Thank you') and redundant instructions from massive automated prompts to drastically reduce monthly AWS/OpenAI bills.
- Understand Multilingual Penalties: LLMs are optimized for English. A sentence in English might cost 10 tokens, while the exact same meaning translated to Japanese or Arabic might cost 40 tokens due to inefficient byte pairing.
