Libraries

How to use K1zE/BPM with Transformers:

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

pipe = pipeline("text-generation", model="K1zE/BPM")
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("K1zE/BPM")
model = AutoModelForMultimodalLM.from_pretrained("K1zE/BPM", 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]:]))

vLLM

How to use K1zE/BPM with vLLM:

Install from pip and serve model

# Install vLLM from pip:
pip install vllm
# Start the vLLM server:
vllm serve "K1zE/BPM"
# Call the server using curl (OpenAI-compatible API):
curl -X POST "http://localhost:8000/v1/chat/completions" \
	-H "Content-Type: application/json" \
	--data '{

				"content": "What is the capital of France?"
			}
		]
	}'

Use Docker

docker model run hf.co/K1zE/BPM

# BPM · GLM-Z1-9B → Qwen3.5-2B

[arXiv:2607.22334](https://arxiv.org/abs/2607.22334) · [Project page](https://bpm-opd.github.io/)

Qwen3.5-2B distilled from GLM-Z1-9B-0414 with **BPM** (Byte-Prefix Marginalization), a
cross-tokenizer on-policy distillation method. Forward-KL arm, step 149.

## Results

Every cell is `avg@8 / pass@8`, matching Table 1 of the paper. Sampling: temperature 0.6,
top-p 0.95, top-k 20, 8 samples per prompt, thinking enabled.

## Usage

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

tok   = AutoTokenizer.from_pretrained("K1zE/BPM")
model = AutoModelForCausalLM.from_pretrained("K1zE/BPM", dtype="auto", device_map="auto")

msgs = [{"role": "user", "content": "What is the remainder of 7^100 modulo 13?"}]
ids  = tok.apply_chat_template(msgs, add_generation_prompt=True, return_tensors="pt").to(model.device)
print(tok.decode(model.generate(ids, max_new_tokens=2048)[0][ids.shape[-1]:], skip_special_tokens=True))
```
