Kontextkosten
~1,811Tokens (Tool-Definitionen)
~2.1 KBTypische Antwortgröße
Mittlere Auswirkung auf die Aufmerksamkeit (1.41% von 128k Kontext)
Dies ist die ungefähre Anzahl der Tokens, die jedes Mal verbraucht werden, wenn die Tools des Servers in den Kontext eines Modells geladen werden. Höhere Werte verringern die Aufmerksamkeit, die für andere Aufgaben verfügbar ist.
