BGE
A series of open-source text embedding models released by the Beijing Academy of Artificial Intelligence (BAAI). BGE models demonstrate strong performance on multiple semantic retrieval benchmarks, support both Chinese and English, and are among the most widely used open-source embedding models.

RAG成本优化杠杆包括：嵌入模型换用本地BGE可省90%以上，向量数据库自托管可省80%，简单查询路由到小模型可省50-80%，高频查询加Redis缓存可省30-60%
Open-source embedding models such as BGE and Nomic-Embed can run on ordinary GPUs or even CPUs without requiring an internet connection.
Even in modern embedding models optimized through instruction fine-tuning or contrastive learning (such as BGE and E5), the anisotropy problem has not been completely eliminated, only reduced in degree.
Mainstream embedding models such as OpenAI's text-embedding-3-small and lightweight versions of the BGE series typically have parameter counts in the range of 100M–500M.
Starting from version 2.8, Blender gradually removed the built-in Game Engine (BGE); the community primarily uses UPBGE or exports scenes to external engines such as Godot/Unity to implement game logic.
The BGE series models on HuggingFace offer better support for Chinese and can be deployed locally to avoid data-export compliance risks.
OpenAI text-embedding, BGE, and Jina are different Embedding models to choose from.
Embedding models (such as BGE and text-embedding-3-small) are much smaller than LLMs and can typically run on CPUs or low-spec GPUs, with inference latency in the millisecond range.
Representative models for dense vector retrieval include DPR, BGE, and text-embedding-ada.
Mainstream text embedding models are typically trained based on contrastive learning, mapping semantically similar text pairs to nearby positions in vector space and pushing unrelated text pairs further apart.
