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)
| Model | Dimensions | Max Tokens | Best For | | -------------------------- | ---------- | ---------- | ----------------------------------- | | voyage-3-large | 1024 | 32000 | Claude apps (Anthropic recommended) | | voyage-3 | 1024 | 32000 | Claude apps, cost-effective | | voyage-code-3 | 1024 | 32000 | Code search | | voyage-finance-2 | 1024 | 32000 | Financial documents | | voyage-law-2 | 1024 | 32000 | Legal documents | | text-embedding-3-large | 3072 | 8191 | OpenAI apps, high accuracy | | text-embedding-3-small | 1536 | 8191 | OpenAI apps, cost-effective | | bge-large-en-v1.5 | 1024 | 512 | Open source, local deployment | | all-MiniLM-L6-v2 | 384 | 256 | Fast, lightweight | | multilingual-e5-large | 1024 | 512 | Multi-language |

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
