Embedding Strategies

Embedding Strategies

Guide to selecting and optimizing embedding models for vector search applications.

When to Use This Skill

• Choosing embedding models for RAG
• Optimizing chunking strategies
• Fine-tuning embeddings for domains
• Comparing embedding model performance
• Reducing embedding dimensions
• Handling multilingual content

Core Concepts

1. Embedding Model Comparison (2026)

2. Embedding Pipeline

Best Practices

Do's

• Match model to use case: Code vs prose vs multilingual
• Chunk thoughtfully: Preserve semantic boundaries
• Normalize embeddings: For cosine similarity search
• Batch requests: More efficient than one-by-one
• Cache embeddings: Avoid recomputing for static content
• Use Voyage AI for Claude apps: Recommended by Anthropic

Don'ts

• Don't ignore token limits: Truncation loses information
• Don't mix embedding models: Incompatible vector spaces
• Don't skip preprocessing: Garbage in, garbage out
• Don't over-chunk: Lose important context
• Don't forget metadata: Essential for filtering and debugging
