Best Reranker Model for RAG

Pros and Cons of Different Models

RAGFlow

  • Pros:
    • Successful when combined with offline LLMs and rerankers
    • Utilizes a <8GB RAM model
  • Cons:
    • Potential retrieval overhead
    • Limited self-hostable options

Gemini 2.0 Flash Experimental

  • Pros:
    • Uses infini-attention for 1M token context
    • Succeeds in all retrievals
    • Offers comprehensive Google AI Studio and RAGFlow support
  • Cons:
    • Requires specific setup for successful use

TensorFlow IDF, BM25, Snowflake Embed Model

  • Pros:
    • Variety in retrieval options
  • Cons:
    • Limited discussion in the Reddit comments on its effectiveness

Deepseek R1

  • Pros:
    • Utilizes locally running Ollama models
    • Llama 3 or QWEN quantized models
  • Cons:
    • Limited hardware requirements information provided

Hybrid Search and other Techniques

  • Pros:
    • Promising for enhancing retrieval accuracy
  • Cons:
    • Limited discussion on specific models or implementations

LLMs (Large Language Models) and RAG Frameworks in General

  • Pros:
    • Useful for semantically capturing information
  • Cons:
    • Limited in complex reasoning scenarios
    • Issues with complex retrieval tasks

Recommendations and Further Considerations

  • Consider exploring models such as Infini-Attention, YOCO, and Mnemosyne for expanding token capacity and improving retrieval accuracy.
  • Evaluate the time to first response and retrieval overhead when selecting a reranker model for RAG.
  • Look into vector databases with built-in support for hybrid search, such as Milvus.
  • Explore the use of knowledge graphs for visualizing RAG results and potential integration with tools like OpenWebUI.

Ultimately, the choice of the best reranker model for RAG will depend on factors such as resource constraints, specific use cases, and desired retrieval accuracy. Additional testing and experimentation may be necessary to determine the most effective solution for a given project or application.
