harrier-oss-v1-0.6b

This repository contains microsoft/harrier-oss-v1-0.6b together with a Furiosa Executable Bundle (FXB) for running it on FuriosaAI RNGD with Furiosa-LLM. The same model also runs on other frameworks (such as Sentence Transformers and Transformers); for usage with those, see the upstream microsoft/harrier-oss-v1-0.6b model card.

Overview

Harrier OSS v1 is a family of multilingual text-embedding models developed by Microsoft. The 0.6B model uses a dense, decoder-only Qwen3 architecture, but it is trained with Harrier's own multilingual, instruction-aware embedding recipe rather than the Qwen3-Embedding training recipe. It produces 1,024-dimensional embeddings through last-token pooling and L2 normalization. It is designed for retrieval, clustering, semantic similarity, classification, bitext mining, and reranking. Its intended use is the same as the upstream microsoft/harrier-oss-v1-0.6b, and it is released under the MIT License.

Architecture: Qwen3 (dense), Qwen3Model
Input / Output: Text / Embeddings (vector)
Supported Inference Engine: Furiosa LLM
Supported Hardware: FuriosaAI RNGD

Quantization

No quantization — the model runs in its native BF16 precision.

Parallelism Strategy

On RNGD, harrier-oss-v1-0.6b runs with a tensor-parallel size of 8 PEs, which maps to a single RNGD card (8 PEs per card).

Usage

To run this model with Furiosa-LLM, follow the examples below after installing Furiosa-LLM and its prerequisites. You can use the model either online through the OpenAI-compatible server or offline through the Furiosa-LLM Python API.

Launch the server

Serve the model by passing its furiosa-ai/<repo> identifier:

# Launch the server, listening on port 8000 by default
furiosa-llm serve furiosa-ai/harrier-oss-v1-0.6b

When the server is ready, you will see:

INFO:     Started server process [27507]
INFO:     Waiting for application startup.
INFO:     Application startup complete.
INFO:     Uvicorn running on http://0.0.0.0:8000 (Press CTRL+C to quit)

Basic Usage

The server exposes an OpenAI-compatible /v1/embeddings endpoint. Harrier is instruction-aware: prepend a one-sentence task description to each query in the Instruct: ...\nQuery: ... format, and do not add the instruction to documents. For more details, see the base model card. Request embeddings with curl:

curl http://localhost:8000/v1/embeddings \
    -H "Content-Type: application/json" \
    -d '{
    "model": "furiosa-ai/harrier-oss-v1-0.6b",
    "input": [
      "Instruct: Given a web search query, retrieve relevant passages that answer the query\nQuery: summit define",
      "Definition of summit: the highest point of a mountain."
    ]
    }' \
    | python -m json.tool

Because the endpoint is OpenAI-compatible, you can also use the OpenAI Python client:

python

from openai import OpenAI

client = OpenAI(base_url="http://localhost:8000/v1", api_key="EMPTY")

query = (
    "Instruct: Given a web search query, retrieve relevant passages that answer the query\n"
    "Query: summit define"
)
document = "Definition of summit: the highest point of a mountain."

response = client.embeddings.create(
    model="furiosa-ai/harrier-oss-v1-0.6b",
    input=[query, document],
)

for data in response.data:
    print(f"Index {data.index}: {len(data.embedding)} dimensions")

Advanced Usage

For offline use, load the model with the LLM constructor (the FXB shipped in the repo is discovered automatically) and call embed to obtain L2-normalized dense vectors. Their dot product is therefore the cosine similarity:

python

from furiosa_llm import LLM

query = (
    "Instruct: Given a web search query, retrieve relevant passages that answer the query\n"
    "Query: summit define"
)
document = "Definition of summit: the highest point of a mountain."

with LLM("furiosa-ai/harrier-oss-v1-0.6b") as llm:
    outputs = llm.embed([query, document])
    embeddings = [output.outputs.embedding for output in outputs]

similarity = sum(a * b for a, b in zip(*embeddings, strict=True))
print(f"Cosine similarity: {similarity:.4f}")
