| # R3-Embedding-0.6B |
|
|
| The latest agent skill retrieval model at the 0.6B scale. **R3-Embedding** is the bi-encoder |
| (recall) stage of R3-Skill's two-stage retriever for query-conditional agent skill retrieval. It |
| embeds a query and every skill independently and ranks candidates by cosine similarity, paired |
| with [R3-Rerank-0.6B](https://huggingface.co/tencent/R3-rerank-0.6b) for reranking. |

| ## Usage |
|
|
| ```python |
| from sentence_transformers import SentenceTransformer |
| |
| model = SentenceTransformer("tencent/R3-embedding-0.6b") |
| query_embedding = model.encode_query("I need to compose music") |
| document_embeddings = model.encode_document([ # The format is "name | description | skill_md" |
| "music-composer | Composes original music | Creates music for various media formats ...", |
| "music-lyricist | Writes lyrics for songs | Creates lyrics for various music genres ...", |
| "music-editor | Edits and mixes music tracks | Provides audio editing and mixing services ...", |
| ]) |
| similarities = model.similarity(query_embedding, document_embeddings) |
| print(similarities) |
| # tensor([[0.7410, 0.5510, 0.5028]]) |
| ``` |
