Frequently Asked Questions about Aya Expanse 8B
How much does the Aya Expanse 8B API cost per 1M tokens?+
Aya Expanse 8B by Cohere is priced at $0.08 per 1M input tokens and $0.16 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0.02 per 1M tokens, and asynchronous Batch API requests receive a 50% discount.
Should I use a $20/month subscription or the Aya Expanse 8B 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 Aya Expanse 8B's context window?+
Aya Expanse 8B features a 8K tokens context window, which equals approximately 6,144 English words or ~16 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 4,096 tokens.
Can I run Aya Expanse 8B locally on my own GPU (Open Weights)?+
Yes, Aya Expanse 8B (8B) releases open weights that can be self-hosted locally or on private cloud GPUs using vLLM, Ollama, SGLang, or llama.cpp.
Does Cohere train on data sent to the Aya Expanse 8B API, and is commercial use allowed?+
100% Isolated when self-hosted on private GPUs or VPC. License tier: Open-Weights Research & Commercial License. Full commercial ownership of generated outputs. Supported deployment channels include: Self-Hosted GPU (vLLM / Ollama), Private VPC, or Managed Serverless API.
How does Aya Expanse 8B perform on coding and reasoning benchmarks?+
Aya Expanse 8B achieves a composite Intelligence Index of 36/100, scoring 24% on SWE-bench Verified, 40% on GPQA Diamond, 62% on MMLU-Pro, and 1205 pts on Chatbot Arena Elo.
What is Aya Expanse 8B best used for?+
Aya Expanse 8B is best suited for: multilingüe cliente interaction, bajo-resource idioma traducción, y perimetral implementaciones. Assessment: un brilliant de código abierto contribution un linguistic equity y global AI accessibility.

AI Glossary & Architecture Concepts
View full glossary →Key machine learning concepts and benchmarks relevant to Aya Expanse 8B:
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.
