The Compression Transformer

Letting a neural network build the compression graph

OpenZL compresses data by chaining processing layers in any order. This is powerful, but requires careful configuration: choosing the right combination of codecs for a given input has always been its greatest challenge. The Compression Transformer now makes that choice automatically, building the compression graph on the fly, one decision at a time. It needs no per-source training, no manual tuning, and no change on the decompression side. It is available from both the API and the CLI.
