Bonsai 2 27B: Near-Lossless Compression in a 9x Smaller Footprint

Bonsai 2 27B is a near-lossless compression algorithm that achieves a 9x smaller footprint than the previous version, Bonsai 2 27A. This is made possible by a new technique called 'Patch-based' compression. The algorithm is still not open-source, but the authors claim it can compress images up to 9 times smaller than the original size without significant loss of quality. Bonsai 2 27B is designed for high-performance applications such as graphics, video and 3D rendering, and is expected to be used in industries such as gaming, film, and architecture.
