Qwen3.5-0.8B Intent Classification

A lightweight, quantized GGUF model fine-tuned on top of Qwen3.5-0.8B for conversational intent classification. Designed to run efficiently on consumer hardware with no GPU required.

Intended Use

This model is designed to classify user intents from conversational text. It is suitable for:

• Chatbot routing and intent detection
• Virtual assistant pipelines
• Customer support automation
• NLU (Natural Language Understanding) systems

Quickstart

Using llama.cpp

# Download the model
huggingface-cli download Nikhil1581/qwen3.5-0.8b-intent-classification Qwen3.5-0.8B.Q4_K_M.gguf --local-dir ./models

# Run inference
./llama-cli -m ./models/Qwen3.5-0.8B.Q4_K_M.gguf \
  -p "Classify the intent of the following message: 'What is the weather like today?'" \
  -n 128

Using llama-cpp-python

from llama_cpp import Llama

llm = Llama(
    model_path="./models/Qwen3.5-0.8B.Q4_K_M.gguf",
    n_ctx=2048,
)

prompt = """You are an intent classification assistant. 
Classify the intent of the user message below into a single intent label.

User message: "Book me a flight to New York for next Monday."
Intent:"""

output = llm(prompt, max_tokens=64, stop=["\n"])
print(output["choices"][0]["text"].strip())

Using Ollama

# Create a Modelfile
cat <<EOF > Modelfile
FROM ./models/Qwen3.5-0.8B.Q4_K_M.gguf
SYSTEM "You are an intent classification assistant. Given a user message, respond with the most appropriate intent label."
EOF

ollama create qwen-intent -f Modelfile
ollama run qwen-intent "Cancel my subscription"

Quantization Details

This model uses Q4_K_M quantization, which offers a good balance between size, speed, and accuracy.

Hardware Requirements

---

Limitations

• Output quality depends on prompt formatting — clear, structured prompts yield better results.
• As a 0.8B parameter model, performance on complex or ambiguous intents may be limited compared to larger models.
• Primarily optimized for English-language inputs.
