A high-efficiency 33.5 million parameter embedding model that dominates the MTEB leaderboard for English retrieval tasks.

Engineered by the Beijing Academy of Artificial Intelligence (BAAI), BGE-small-en-v1.5 delivers elite performance in a compact 133MB footprint. It processes 512-token sequences into 384-dimensional vectors, balancing low latency with high accuracy for RAG pipelines and semantic search. This model currently maintains top-tier rankings on the Massive Text Embedding Benchmark (MTEB) by outperforming significantly larger architectures in retrieval, reranking, and clustering metrics.

## Recent Public Talks and Demos

### [DoppelGoner: Building a Vector-Based Entity Clustering System for Federated Data](https://seattle.aitinkerers.org/talks/rsvp_eeZXANggQPM)

I'll demonstrate how I built DoppelGoner, an open-source Rust implementation that uses transformer embeddings and graph-based clustering to solve entity reconciliation across federated databases. The demo will include: Live code walkthrough of the vector similarity pipeline using BGE-small embeddings Technical deep-dive into the incremental processing architecture that enables efficient repeated runs Demonstration of the graph-based cluster consolidation using petgraph for transitive relationship discovery Performance optimization techniques for pgvector operations and parallel embedding generation Live demo of semantic service matching where I'll show how the system identifies semantically similar services even with different terminology I'll run everything live on my MacBook showing that sophisticated AI tooling can be deployed efficiently without massive compute resources.
