L3: A GPU-Native Co-Designed Data Format for Learned Lossless Lightweight Compression

Summary: L3 co-designs a GPU-native learned lossless codec around SLAP’s lane-major residual layout, warp-cooperative decoding, and fully on-device compression. It delivers TB/s decompression, 1.2–2.6B random accesses/s, and strong compression, outperforming GPU baselines. (summarized by gpt-5.6-luna on Jul 26 2026)
