jina-embeddings-v5-text-small-clustering: Clustering-Targeted Embedding Distillation

Blog | Technical Report | Jina API | EIS

Model Overview

jina-embeddings-v5-text-small-clustering is a compact, high-performance text embedding model designed for clustering.

It is part of the jina-embeddings-v5-text model family, which also includes jina-embeddings-v5-text-nano, a smaller model for more resource-constrained use cases.

Trained using a novel approach that combines distillation with task-specific contrastive losses, jina-embeddings-v5-text-small-clustering outperforms existing state-of-the-art models of similar size across diverse embedding benchmarks.

Feature	Value
Parameters	677M
Supported Tasks	`clustering`
Max Sequence Length	32768
Embedding Dimension	1024
Matryoshka Dimensions	32, 64, 128, 256, 512, 768, 1024
Pooling Strategy	Last-token pooling
Base Model	Qwen/Qwen3-0.6B-Base

Training and Evaluation

For training details and evaluation results, see our technical report.

Usage

Requirements

The following Python packages are required:

transformers>=5.1.0
torch>=2.8.0
peft>=0.15.2
vllm>=0.15.1

Optional / Recommended

flash-attention: Installing flash-attention is recommended for improved inference speed and efficiency, but not mandatory.
sentence-transformers: If you want to use the model via the sentence-transformers interface, install this package as well.

via vLLM

from vllm import LLM

# Initialize model
name = "jinaai/jina-embeddings-v5-text-small-clustering"
model = LLM(
    model=name,
    dtype="float16",
    runner="pooling",
    pooler_config=PoolerConfig(seq_pooling_type="LAST", normalize=True)
)

# Create text prompts
document1 = "Overview of climate change impacts on coastal cities"
document1_prompt = f"Document: {document1}"

document2 = "The impacts of climate change on large cities"
document2_prompt = f"Document: {document2}"

# Encode all prompts
prompts = [document1_prompt, document2_prompt]
outputs = model.encode(prompts, pooling_task="embed")


embed_document1 = outputs[0].outputs.data
embed_document2 = outputs[1].outputs.data

via llama.cpp (GGUF)

After installing llama.cpp one can run llama-server to host the embedding model as OpenAI API compatible HTTP server with the respective model version:

llama-server -hf jinaai/jina-embeddings-v5-text-small-clustering:F16 --embedding --pooling last -ub 32768

Client:

curl -X POST "http://127.0.0.1:8080/v1/embeddings" \
  -H "Content-Type: application/json" \
  -d '{
    "input": [
      "Document: A beautiful sunset over the beach",
      "Document: Un beau coucher de soleil sur la plage",
      "Document: 海滩上美丽的日落",
      "Document: 浜辺に沈む美しい夕日",
      "Document: Golden sunlight melts into the horizon, painting waves in warm amber and rose, while the sky whispers goodnight to the quiet, endless sea."
    ]
  }'
