Sollte ich dies verwenden
Qualität und Sicherheit
A
Basierend auf einer automatisierten Analyse der Tool-Definitionen und der Einhaltung des Protokolls.
Kontextkosten
~3,926Tokens (Tool-Definitionen)
~15.7 KBTypische Antwortgröße
Erhebliche Auswirkung auf die Aufmerksamkeit (3.07% 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.
