Libraries

How to use hf-internal-testing/tiny-muse-spark with Transformers:

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

pipe = pipeline("image-text-to-text", model="hf-internal-testing/tiny-muse-spark")
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)

# pip install -U transformers accelerate
# Load model directly
from transformers import AutoProcessor, AutoModelForMultimodalLM

processor = AutoProcessor.from_pretrained("hf-internal-testing/tiny-muse-spark")
model = AutoModelForMultimodalLM.from_pretrained("hf-internal-testing/tiny-muse-spark", 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=256)
print(processor.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

muse-spark-tiny

Randomly initialised tiny Muse Spark checkpoint for shape/plumbing/TP smoke tests. No weight comes from the released checkpoint — do not use for any quality evaluation.

Built from the release's config.json with exactly two knobs shrunk:

	release	tiny
`text_config.num_hidden_layers`	62	6
`text_config.num_local_experts`	256	8
parameters	822 B	9.48 B (1.15 %)
size (bf16)	1644 GB	18.97 GB, 5 shards

Everything else matches the release: vision tower 50 layers, audio encoder 4 stages, hidden_size 8192, moe_intermediate_size 4096, vocab 202048 with an untied head, plus the release tokenizer, processor config and chat template.

The per-layer lists layer_types, layer_rope_theta and mlp_layer_types were dropped from the source config so MuseSparkTextConfig.__post_init__ re-derives them at depth 6 rather than truncating the 62-entry lists — the [w, w, w, 0] sliding/NoPE pattern is counted backward from the last layer, so NoPE correctly lands on layers 1 and 5.

Parameter split:

component	params
text MoE blocks	2.819 B
vision tower + projector	1.928 B
embeddings	1.655 B
lm_head (untied)	1.655 B
text attention + norms	1.309 B
audio encoder	0.118 B
