jina-embeddings-v5-text-small-classification: Classification-Targeted Embedding Distillation

Blog | Technical Report | API

Model Overview

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

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-classification outperforms existing state-of-the-art models of similar size across diverse embedding benchmarks.

Feature	Value
Parameters	677M
Supported Tasks	`classification`
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

via vLLM

from vllm import LLM

# Initialize model
name = "jinaai/jina-embeddings-v5-text-small-classification"
model = LLM(model=name, task="embed", dtype="bfloat16")

# 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
