Amazon S3 Vector Search
Leveraging Amazon S3 as a storage layer for vector databases, enabling 70-95% cost reduction for certain use cases. S3's low storage costs make it attractive for large-scale vector datasets with appropriate access patterns.
Perpetual Sandbox
Sandbox architecture that maintains state indefinitely while scaling costs to zero during idle periods. Pioneered by Blaxel with sub-25ms resume times from standby mode.
Breaking the Storage-Compute Bottleneck in Billion-Scale ANNS
A 2025 research paper presenting a GPU-driven asynchronous I/O framework for billion-scale approximate nearest neighbor search. The system addresses the fundamental bottleneck of data movement between storage and compute in large-scale vector search.
Semantic Caching
A caching technique that uses vector embeddings to identify and reuse responses for semantically similar queries, reducing LLM costs and latency. Unlike traditional caches based on exact matches, semantic caching achieves cache hit ratios of up to 92% by matching queries based on semantic similarity.
LLM Caching for Vector Search
Caching strategies for LLM and vector search systems including semantic caching, embedding caching, and response caching to reduce costs and improve latency in RAG applications.
LazyGraphRAG
Cost-optimized variant of GraphRAG that reduces indexing cost to 0.1% of full GraphRAG while maintaining retrieval quality. Designed for resource-constrained deployments where traditional GraphRAG's 100-1000x higher indexing cost is prohibitive.
