Instructions to use Redhanuman/Shadow-0.7B with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use Redhanuman/Shadow-0.7B with Transformers:

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

pipe = pipeline("text-generation", model="Redhanuman/Shadow-0.7B")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# pip install -U transformers accelerate
# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("Redhanuman/Shadow-0.7B")
model = AutoModelForCausalLM.from_pretrained("Redhanuman/Shadow-0.7B", 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=256)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

🌑 Shadow 0.7B (Reasoning + Coding Edition)

Shadow 0.7B is a specialized Small Language Model (SLM) optimized for logical reasoning, competitive programming, and chain-of-thought processing.

Built on the Qwen3 0.6B architecture and fine-tuned using Unsloth, Shadow delivers surprising reasoning depth and "thinking-first" responses uncommon for a model of this size.

Key Features

🧠 Structured Reasoning: Uses <think> style internal reasoning patterns to improve answer quality.
💻 Coding Specialist: Excels at Python, C++, and algorithmic problem-solving.
⚡ Ultra-Lightweight: Runs on CPU, T4, mobile, or even low-VRAM consumer GPUs.

💻 Quick Start (Python)

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_name = "Redhanuman/Shadow-0.7B"

model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype="auto",
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained(model_name)

prompt = "Write a Python script to check for palindromes. Explain your logic."
messages = [
    {"role": "user", "content": prompt}
]

text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)

inputs = tokenizer([text], return_tensors="pt").to(model.device)

generated_ids = model.generate(
    **inputs,
    max_new_tokens=1024
)

print(tokenizer.decode(generated_ids[0], skip_special_tokens=True))
