Frequently Asked Questions about Grok 2
How much does the Grok 2 API cost per 1M tokens?+
Grok 2 by xAI is priced at $2 per 1M input tokens and $10 per 1M output tokens. With prompt caching enabled, cached input tokens cost $1 per 1M tokens, and asynchronous Batch API requests receive a 50% discount.
Should I use a $20/month subscription or the Grok 2 pay-as-you-go API?+
A flat $20/month consumer subscription is predictable for daily interactive chat and manual coding. However, if you are building software, running automated workflows, or sending low-to-moderate volume with prompt caching enabled, the pay-as-you-go API is typically far more cost-effective and offers higher rate limits without manual UI caps.
How many words and pages fit in Grok 2's context window?+
Grok 2 features a 131K tokens context window, which equals approximately 98,304 English words or ~262 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 8,192 tokens.
Can I run Grok 2 locally on my own GPU (Open Weights)?+
No, Grok 2 is a proprietary closed-weights model hosted by xAI. It cannot be downloaded for local GPU execution and must be accessed via xAI's official API or cloud platform.
Does xAI train on data sent to the Grok 2 API, and is commercial use allowed?+
API payloads are excluded from model training by default. License tier: Proprietary Commercial API (xAI Terms). Full commercial ownership of generated outputs. Supported deployment channels include: xAI Cloud API & Enterprise Endpoints.
How does Grok 2 perform on coding and reasoning benchmarks?+
Grok 2 achieves a composite Intelligence Index of 45/100, scoring 36.5% on SWE-bench Verified, 56% on GPQA Diamond, 74.5% on MMLU-Pro, and 1295 pts on Chatbot Arena Elo.
What is Grok 2 best used for?+
Grok 2 is best suited for: en tiempo real trending news síntesis, visual STEM razonamiento, y interactivo X aplicaciones. Assessment: de xAI breakthrough insignia demonstrating que raw compute scaling y datos calidad puede rival el de industry mejor.

AI Glossary & Architecture Concepts
View full glossary →Key machine learning concepts and benchmarks relevant to Grok 2:
La unidad básica de texto que procesa un modelo de lenguaje, que normalmente equivale a 3 o 4 caracteres o aproximadamente 0,75 palabras. Por ejemplo, una frase típica se divide en varios tokens.
Un conjunto estandarizado de pruebas para evaluar y comparar objetivamente las capacidades de distintos modelos de IA en tareas como programación (SWE-bench) o matemáticas avanzadas (AIME).
La cantidad máxima de tokens que un modelo puede considerar a la vez, incluyendo tanto la entrada que lee como la salida que genera. Una ventana de 1.000.000 de tokens puede procesar unas 750.000 palabras en una sola petición.
La capacidad de un modelo de detectar la necesidad de una función externa y emitir argumentos JSON estructurados para ejecutar API, búsquedas web o consultas a bases de datos.
Un protocolo abierto desarrollado por Anthropic que permite a los agentes de IA conectarse de forma estandarizada a sistemas de archivos locales, entornos de desarrollo y servicios externos.
Una optimización donde los proveedores almacenan estados de atención previos para prefijos de prompts frecuentes, reduciendo el coste de entrada hasta en un 90% y acelerando la respuesta.
Las puntuaciones de benchmarks, precios por token y límites de tasa evolucionan rápidamente. Verifique siempre las especificaciones actuales en la documentación oficial del proveedor.
