Use your Nvidia GPU's VRAM as swap space on Linux

https://opengraph.githubassets.com/2dbdd4438347db6dfb5d180394307019da2d2c3fdca12b1e830e1b00d2dd2bb3/c0deJedi/nbd-vram

The Unreasonable Redundancy of Nature's Protein Folds

https://research.ligo.bio/posts/unreasonable-redundancy-of-natural-protein-folds/assets/antibody-antigen-scaling.png
Researchers improved biomolecular modeling by scaling models, compute, and data, but found that natural protein sequences are vast and their folds are more redundant than sequence counts suggest. They developed a scalable clustering algorithm to identify reusable structural neighborhoods and found that natural proteins reuse a relatively small set of fold solutions, suggesting that enzyme ...

How we index images for RAG

https://framerusercontent.com/images/qURKX4mwPMBTX9peq1oYfpPQw.png
Kapa's AI assistant uses a vision model at indexing time to describe images as text, then retrieves these descriptions alongside text chunks at query time, improving answer quality and reducing costs. This approach, which involves describing images once at ingestion and storing them as separate text chunks, outperforms query-time vision and is more cost-effective for large-scale applications.
