st.write("*The real democratization of AI can only be achieved by a powerful open-source ecosystem and low prices for memory/GPU usage. Thanks to quantization, we can say bye to float32, and hello binary! Compression-friendly embedding models implemented in int8 and binary can save up to x4 and x32 of memory, storage, and, costs. To achieve X32 compute efficiency and retain ∼96% of retrieval performance, the binary quantization is powered by the normalization of embedding values (either 0 or 1), the calculation of Hamming Distance with only 2 CPU runtimes, and the application of ReRank step of [Yamada et al (2021)](https://arxiv.org/abs/2106.00882). Scalar and binary embeddings revealed great retrieval efficiency with just a minimal degradation of performance, perfect for NLP downstream tasks, semantic search, recommendation systems, and retrieval-augmented generation solutions.*")
