## AI overview

IPIP-0499 has been merged into the IPFS specification and defines configuration profiles for DAG construction. Implementations that conform to the same profile produce the same CID for identical input, enabling direct CID comparison for verification and providing a more performant default for large files.

## Source excerpt

IPIP-0499 makes IPFS CIDs deterministic and consistent across all implementations.
