Costo de contexto

~1,813Tokens (definiciones de herramientas)
~18.4 KBTamaño de respuesta típico
Impacto moderado en la atención (1.42% del contexto de 128k)

Este es el número aproximado de tokens que se consumen cada vez que las herramientas del servidor se cargan en el contexto de un modelo. Los recuentos más altos reducen la atención disponible para otras tareas.
