Key Points

  • A new “project memory” MCP project (linked as mind-mem) was shared, designed to help LLM-based applications recall prior project information.
  • The approach uses hybrid retrieval that combines BM25 keyword search with vector similarity search.
  • It further blends retrieval results using RRF (Reciprocal Rank Fusion) to improve the quality of returned memories.
  • The project is reported to work with FFT on the Qwen3.5-4B model (per the post’s description).
