bge-large-en-v1.5

Use cases

• High-precision semantic search where embedding quality is the primary constraint
• Embedding for legal, medical, or technical domain retrieval requiring fine-grained distinction
• MTEB benchmark baseline as a strong English embedding reference point
• Re-ranking large candidate sets using embedding similarity
• Knowledge base retrieval where 768-dim models underperform

Pros

• Strong MTEB retrieval accuracy at 1024 dimensions
• MIT license for commercial use
• ONNX and text-embeddings-inference compatible for production deployment
• Part of the well-maintained BAAI BGE family with documented benchmarks

Cons

• 1024-dim output doubles storage cost vs. 512-dim alternatives
• Higher inference compute than BGE-small or BGE-base
• English-only; no multilingual or cross-lingual capability
• May provide marginal gains over BGE-base for many standard retrieval tasks
• Newer instruction-following embedding models are competitive at smaller sizes
