  • 1. Fixed-Length Chunking
  • How it works:
  • Example (Fixed number of words per chunk):
  • Integration with Pinecone:
  • Pros: ✅ Simplicity and speed.
  • Cons: ❌ Ignores natural structure.
  • Ideal use cases:
  • 2. Semantic Chunking
  • How it works:
  • Example (Sentence-based chunking with token limit):
  • Integration with Pinecone:
  • Pros: ✅ Maintains context integrity.
  • Cons: ❌ Variable size and complexity.
  • Ideal use cases:
  • 3. Hybrid Chunking (Semantic + Token-Aware)
  • How it works:
  • Example (Accumulating sentences up to a token limit):
  • Integration with Pinecone:
  • Pros: ✅ Balanced approach.
  • Cons: ❌ Increased complexity.
  • Ideal use cases:
  • 4. Dynamic Chunking with Content-Aware Optimization
  • How it works:
  • Example (Content-aware pseudo-code):
  • Integration with Pinecone:
  • Pros: ✅ Maximized relevance through flexibility.
  • Cons: ❌ High complexity and overhead.
  • Ideal use cases:
  • Comparison of Chunking Strategies
  • Context Window and Embedding Model Considerations
