Libraries

How to use kshitijthakkar/deepseek-v4-mini-3B-init with Transformers:

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

pipe = pipeline("text-generation", model="kshitijthakkar/deepseek-v4-mini-3B-init")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("kshitijthakkar/deepseek-v4-mini-3B-init")
model = AutoModelForCausalLM.from_pretrained("kshitijthakkar/deepseek-v4-mini-3B-init")
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]:]))

DeepSeek-V4 Mini (3B) — randomly-initialized architecture replica

Faithful small-scale (~3.2B total / ~1.10B activated per token) replica of the DeepSeek-V4 architecture, sized to be trainable on rented GPUs and to map cleanly onto the full-scale V4-Flash dimensions for weight slicing.

This is a randomly-initialized scaffold — generates noise. Its purpose:

reference architecture for ablation / hyperparameter-search experiments
target for weight transfer / slicing from real V4-Pro / V4-Flash

Quick start

from huggingface_hub import login, snapshot_download
login()  # private repo

local = snapshot_download(repo_id="kshitijthakkar/deepseek-v4-mini-3B-init")

import sys, os
sys.path.insert(0, os.path.join(local, "code"))
import deepseek_v4  # registers DeepseekV4{Config,ForCausalLM} with HF auto classes

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

tok = AutoTokenizer.from_pretrained(local)
model = AutoModelForCausalLM.from_pretrained(local, torch_dtype=torch.bfloat16)
model.eval()

ids = tok.apply_chat_template(
    [{"role": "user", "content": "Hello"}],
    return_tensors="pt", add_generation_prompt=True, return_dict=True,
)
with torch.no_grad():
    out = model(input_ids=ids["input_ids"])
print(out.logits.shape)

Components implemented

mHC (Sinkhorn-Knopp) · CSA + Lightning Indexer · HCA · pure sliding-window · Shared-KV MQA + grouped output projection (per-group wo_a) · partial RoPE + output -i rotation · attention sink · DeepseekMoE with sqrt(softplus) routing · hash-routed early layers · clamped SwiGLU · MTP head · YaRN.

Every component is bit-equivalent in math to the official inference/model.py

kernel.py:hc_split_sinkhorn (FP4/FP8 quantization and Hadamard rotation are skipped — those are inference optimizations, not architecture).
