Unfortunately, the giant squid Architeuthis has not been studied enough to make a comprehensive diet. From the few that have been dissected though, it was discovered that they would eat sperm whales that dive deep underwater.
Their common foods to feed on include various types of small fish, crabs, and shrimp. They have been known to feed on other squid that are smaller than them too. This generally only will occur though when other sources of food are scarce. The squid features a small beak like mouth.
