Cost Optimized Training Execution

via “query-execution-with-cost-based-optimization”

The AI-native database built for LLM applications, providing incredibly fast hybrid search of dense vector, sparse vector, tensor (multi-vector), and full-text.

Unique: Implements cost-based query optimization for vector databases, estimating costs of vector operations (ANN search, BM25 ranking, fusion) alongside traditional SQL operations; uses C++20 modules for compile-time plan specialization.

vs others: More sophisticated than Pinecone (no query optimization) because Infinity automatically selects optimal execution strategy; simpler than Postgres because vector operations have specialized cost models.
