Libraries

How to use Jundot/clef-oQ4e with MLX:

# Make sure mlx-vlm is installed
# pip install --upgrade mlx-vlm

from mlx_vlm import load, generate
from mlx_vlm.prompt_utils import apply_chat_template
from mlx_vlm.utils import load_config

# Load the model
model, processor = load("Jundot/clef-oQ4e")
config = load_config("Jundot/clef-oQ4e")

# Prepare input
image = ["http://images.cocodataset.org/val2017/000000039769.jpg"]
prompt = "Describe this image."

# Apply chat template
formatted_prompt = apply_chat_template(
    processor, config, prompt, num_images=1
)

# Generate output
output = generate(model, processor, formatted_prompt, image)
print(output)

clef-oQ4e

This model was quantized using oQ mixed-precision quantization.

A mixed-precision MLX checkpoint of Cloudflare/clef, a decision model that answers typed questions (noul, choice, score) about text and images with a probability for each option. It includes the Qwen3.8-27B language backbone, the vision encoder and the joint schema head.

The joint schema head (joint_head.safetensors, joint_head_config.json) is copied unchanged from the source. oMLX serves this checkpoint through POST /v1/systemone once decision model support (jundot/omlx#4315) is available.

The effective average is 5.264 bits/weight for the complete checkpoint.

Quantization and Bit Distribution

4-bit affine quantization, group size 64, for most language-backbone projections and the token embeddings.
5-bit affine quantization, group size 64, for projections boosted by measured layer sensitivity.
6-bit affine quantization, group size 64, for the output projection (lm_head).
BF16 for the vision encoder, the joint schema head, norms and the remaining small tensors.

The oQ4e allocation uses measured layer sensitivity and importance-matrix calibration (128 samples x 512 tokens, built-in code and multilingual set).

Storage format	Logical weights	Share of total	Tensor storage	Effective bits/weight
