via “domain-specific embedding models for finance, legal, and code”

Domain-specific embedding models for RAG.

Unique: Fine-tuned embeddings for finance, legal, and code domains that optimize for domain-specific terminology and semantic relationships, outperforming general-purpose embeddings on domain benchmarks while maintaining compatibility with standard vector database infrastructure.
