Turns text in many languages into number vectors for search, clustering and similarity matching, a 0.6B embedding model from Microsoft for developers building retrieval and ranking tools. harrier-oss-v1-0.6b is a kit in the Developer category, listed by Mindket. It is free. This is version 1, last updated on 2026-11-12. Download it on this page, a zip of its files. Nothing in it runs by itself. Made by microsoft ## About ### What it is harrier-oss-v1-0.6b is the mid-sized member of Microsoft's harrier-oss-v1 family of multilingual text embedding models. It converts a piece of text into a vector of 1,024 numbers, so that texts with similar meaning end up close together. It has 596M parameters and accepts up to 32,768 tokens. ### Who it suits It suits developers and data teams who need search, matching or grouping of text across many languages without calling an outside service. Who uses this model | Industry | Who uses it | How they use it | Example | | --- | --- | --- | --- | | Software | Search and app developers | Rank passages for a search query | Find the passage that best answers a question | | Data and analytics | Data teams | Group similar documents | Cluster support tickets by topic | | Localization | Language engineers | Match text with its translation | Mine sentence pairs across languages | | AI products | Retrieval builders | Feed a retrieval step in a question answering tool | Embed documents once and compare queries to them | If you need a model that writes text, you can skip it, since this one only produces vectors. ### Where to use it - Python scripts that use the sentence-transformers library - Python scripts that use the transformers library - Windows, macOS or Linux with Python Jobs it does | Use case | Who | What they get back | | --- | --- | --- | | Retrieval | Search builders | Scores that show which passages match a query | | Clustering | Analysts | Vectors you can group by meaning | | Semantic similarity | Developers | A closeness score between two texts | | Classification and reranking | ML engineers | Vectors that feed a classifier or a reranker | ### How to set it up You need Python and a library that can load the model. - Python with pip - The sentence-transformers library, or transformers - About 1.2 GB of disk space for BF16 weights 1. Install sentence-transformers. 2. Optionally save the files first with the two download commands. 3. Run the sample script. It loads the model and encodes two queries and two passages. ```bash pip install -U huggingface_hub hf download microsoft/harrier-oss-v1-0.6b ``` ### How to use it Encode your queries with a prompt name, encode your documents without one, then multiply the two sets of vectors to get scores. The model's config file defines ready-made prompt names for query types, including web\_search\_query. You can also pass your own instruction as the prompt. ```python from sentence_transformers import SentenceTransformer model = SentenceTransformer("microsoft/harrier-oss-v1-0.6b", model_kwargs={"dtype": "auto"}) queries = [ "how much protein should a female eat", "summit define", ] documents = [ "As a general guideline, the CDC's average requirement of protein for women ages 19 to 70 is 46 grams per day. But, as you can see from this chart, you'll need to increase that if you're expecting or training for a marathon. Check out the chart below to see how much protein you should be eating each day.", "Definition of summit for English Language Learners. : 1 the highest point of a mountain : the top of a mountain. : 2 the highest level. : 3 a meeting or series of meetings between the leaders of two or more governments." ] query_embeddings = model.encode(queries, prompt_name="web_search_query") document_embeddings = model.encode(documents) scores = (query_embeddings @ document_embeddings.T) * 100 print(scores.tolist()) ``` ### Example You encode a nutrition question and two passages, one about daily protein for women and one defining a mountain summit. The printed scores are higher for the protein passage, which is the one that answers the question. ### For newcomers and experts Think of an embedding as a fingerprint of a text's meaning. Two texts that mean similar things get fingerprints that sit close together. A first small test is the sample script with your own question and two short passages. The model is decoder-only. It pools the final token and normalizes the vector with L2. Training used contrastive objectives on a large multilingual mix, and the 270m and 0.6b sizes also learned by distillation from larger embedding models. Queries want a one-sentence task instruction, while documents need none. Text goes in → Decoder-only model reads it → Final token is pooled → L2-normalized vector comes out ### Good to know Hugging Face lists many languages. The card ranks the family on Multilingual MTEB v2 and places the 0.6b size between the 270m and 27b models. Other people have published 28 quantized and 15 fine-tuned versions. Multilingual MTEB v2 score by size | Label | Value | | --- | --- | | 270m | 66.5 points | | 0.6b | 69.0 points | | 27b | 74.3 points | - License: MIT. - Cost to run: none named. - Data it reaches: the files come from Hugging Face, and the text you encode stays on your own computer. - Not for: writing or chatting, since it only turns text into vectors. ## README ````markdown # harrier-oss-v1-0.6b Turns text in many languages into number vectors for search, clustering and similarity matching, a 0.6B embedding model from Microsoft for developers building retrieval and ranking tools.
