Okapi is a biweekly magazine published by the Bayard Presse group since 1971. At the time, it was intended for former readers of Pomme d'Api, once they had learned to read. After the creation of Astrapi, Okapi refocused on the middle school audience (10-15 years old). Okapi's universe is in a way the ancestor of the current Images Doc, a documentary journal of the same press group.
Issue 1000 was released on April 15, 2015.
