Libraries

How to use EmbeddedLLM/Inkling-Small-MXFP4 with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("image-text-to-text", model="EmbeddedLLM/Inkling-Small-MXFP4")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
pipe(text=messages)

# Load model directly
from transformers import AutoProcessor, AutoModelForMultimodalLM

processor = AutoProcessor.from_pretrained("EmbeddedLLM/Inkling-Small-MXFP4")
model = AutoModelForMultimodalLM.from_pretrained("EmbeddedLLM/Inkling-Small-MXFP4", device_map="auto")
messages = [
    {
        "role": "user",
        "content": [
            {"type": "image", "url": "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/p-blog/candy.JPG"},
            {"type": "text", "text": "What animal is on the candy?"}
        ]
    },
]
inputs = processor.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Inkling-Small-MXFP4

Model Overview

Model architecture: Thinking Machines Lab Inkling-Small
- Parameters: 276B total / 12B active
- Input: Text, image, audio
- Output: Text
Validated inference engine: vLLM
Model optimizer: AMD Quark (0.12.post1+rocm72.torch2.11)
- Quantized layers: MoE routed experts in transformer layers 3 through 41
- Weight quantization: OCP MXFP4, static, group size 32, E8M0 scales
- Activation quantization: OCP MXFP4, dynamic, group size 32, E8M0 scales

This checkpoint was built from thinkingmachines/Inkling-Small revision b2d4f225a02032c5d154bff748ab5a00c5ca26e4 by applying AMD Quark OCP MXFP4 quantization to the BF16 routed experts. Routed-expert weights are stored as packed MXFP4 weights with E8M0 scales. Dense layers 0 through 2, attention, shared experts, embeddings, norms, the audio and vision towers, MTP, and other non-routed components remain in their source formats.

Environment

The file-to-file conversion and validation targeted AMD gfx950 and used:

Container: docker.io/rocm/vllm-dev:nightly_main_20260714
Python: 3.12
ROCm/HIP: 7.2
PyTorch: 2.11.0+gitd0c8b1f
AMD Quark: 0.12.post1+rocm72.torch2.11
Expert chunk size: 8

The paired quality evaluation used the same GPU type and TP8 topology, with Transformers 5.14.1 and vLLM commit 846e2d01a0be00acf31f1a354059c7c302c93042 (0.23.1rc1.dev1212+g846e2d01a).
