deepseek-v3-tiny-random-GGUF

QuantFactory/deepseek-v3-tiny-random-GGUF

This is quantized version of yujiepan/deepseek-v3-tiny-random created using llama.cpp

Original Model Card

This model is for debugging. It is randomly initialized with the config from deepseek-ai/DeepSeek-V3 but is of smaller size.

⚠️Note: At this moment, this repo does not contain the Multi-Token Prediction (MTP) module as explained here.

Usage:

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "yujiepan/deepseek-v3-tiny-random"
device = torch.device("cuda")

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id, trust_remote_code=True,
).eval().to(device)

prompt = 'Hello!'
messages = [
    {"role": "system", "content": "You are a helpful assistant."},
    {"role": "user", "content": prompt}
]

inputs = tokenizer.apply_chat_template(
    messages, tokenize=True, add_generation_prompt=True, return_tensors="pt"
).to(device)

with torch.inference_mode():
    outputs = model.generate(
        inputs,
        max_new_tokens=16,
        do_sample=False,
        use_cache=True,
    )
string = tokenizer.decode(outputs[0])
print(string)
