Introduction to Gilial

Gilial is an intelligent vector compression system for Pinecone indexes. It helps you reduce storage costs and improve query performance by removing low-scoring vectors while maintaining search quality.

Vector databases like Pinecone can grow unbounded as you add more embeddings. Over time, your index accumulates:

  • Low-quality vectors that don’t contribute to search relevance
  • Redundant or duplicate vectors
  • Outdated vectors that are no longer needed

Gilial solves this by analyzing your vectors and intelligently removing the lowest-scoring ones based on L2 norm calculations.

  • Reduce storage costs by removing unnecessary vectors
  • Lower API costs through smaller index sizes
  • Decrease bandwidth requirements for index transfers
  • Faster nearest-neighbor searches with smaller datasets
  • Improved cache hit rates
  • Lower query latency
  • Dry-run mode lets you preview changes before applying
  • Multiple compression strategies (Balanced, Aggressive)
  • Clear metrics on impact and savings
  1. Sample - Connect to your Pinecone index and sample vectors
  2. Score - Calculate L2 norm for each vector to determine quality
  3. Delete - Remove low-scoring vectors based on your chosen strategy

The process is fast, deterministic, and reversible (with backups).
