	# Clef-Flash (4-bit NF4 Quantized)

	This repository contains the 4-bit NF4 quantized version of Cloudflare's Clef-Flash multimodal decision model.

	- Base Model: [Cloudflare/clef-flash](https://huggingface.co/Cloudflare/clef-flash)
	- Quantization: 4-bit NormalFloat (NF4) with double quantization via `bitsandbytes`
	- Compute Dtype: `bfloat16`
	- Backbone: Qwen3.5-9B
	- Joint Schema Head: Unquantized BF16 precision for accurate scoring and routing
	- Format: Safetensors

	## Quickstart / Usage

	```python
	import sys
	import torch
	from huggingface_hub import snapshot_download

	path = snapshot_download("meossistant/clef-flash-4bit")
	sys.path.insert(0, path)
	from joint_schema_model import load_release_model, systemone

	model, processor = load_release_model(path, device="cuda")

	response = systemone(model, processor, {
	"model": "clef-flash",
	"state": "Our checkout started returning errors and orders are blocked.",
	"questions": {
	"department": {
	"type": "choice",
	"instructions": "Which team should handle the message?",
	"criteria": {"billing": "Payments or invoices", "technical": "Bugs or outages"},
	},
	"urgency": {"type": "score", "criteria": ["Can wait", "This week", "Today"]},
	"outage": {"type": "noul", "instructions": "Is a service down?"},
	},
	})
	print(response["answers"])
	```

	## Overview

	Clef-Flash is a 9B multimodal model that turns a state and a schema of typed questions into decisions in a single forward pass.
	This 4-bit quantized version reduces the VRAM requirement to ~6 GB, making it easily runnable on consumer GPUs.
