Instructions to use tiny-random/deepseek-v4-bf16 with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use tiny-random/deepseek-v4-bf16 with Transformers:

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

pipe = pipeline("text-generation", model="tiny-random/deepseek-v4-bf16")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("tiny-random/deepseek-v4-bf16")
model = AutoModelForCausalLM.from_pretrained("tiny-random/deepseek-v4-bf16", device_map="auto")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.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(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

vllm reports:

(EngineCore pid=979) File "/workspace/vllm/models/deepseek_v4/amd/model.py", line 860, in load_weights
(EngineCore pid=979) param = params_dict[name]
(EngineCore pid=979) ~~~~~~~~~~~^^^^^^
(EngineCore pid=979) KeyError: 'hc_head.hc_base'
Loading safetensors checkpoint shards: 0% Completed | 0/1 [00:00<?, ?it/s]

vllm expects the weight names to be hc_head_base.
Other weight names are also incorrect.
