ShaziLLM-1B

ShaziLLM-1B is a compact 1.08B-parameter instruction and reasoning language model designed for coding, structured instruction following, tool use, and local deployment. This repository contains the normal BF16 Transformers checkpoint.

For lower-memory CPU and browser inference, use ShaziLLM-1B-ONNX.

Quick start

pip install -U transformers torch accelerate

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

model_id = "Sharjeelbaig/ShaziLLM-1B"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    dtype=torch.bfloat16,
    device_map="auto",
)

messages = [{"role": "user", "content": "Write a Python function to merge two sorted lists."}]
text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True,
)
inputs = tokenizer(text, return_tensors="pt").to(model.device)

with torch.inference_mode():
    output = model.generate(
        **inputs,
        max_new_tokens=256,
        do_sample=False,
    )

new_tokens = output[0, inputs.input_ids.shape[1]:]
print(tokenizer.decode(new_tokens, skip_special_tokens=True))

Model details

Item	Value
Parameters	1.08B
Layers	24
Hidden size	1536
Attention heads / KV heads	16 / 2
Vocabulary	130,560
Maximum configured context	131,072 tokens
Weight format	BF16 Safetensors
Architecture	Llama-compatible causal language model

The configured context limit is not a practical memory recommendation. Start with a much shorter context on low-memory hardware and increase it only after measuring KV-cache usage.

ShaziLLM alignment

The release received a focused identity-alignment and capability-retention pass before export. A rank-8 LoRA adapter targeting the query and value projections was trained for four epochs at a 1e-4 learning rate on 48 short examples, with 1,032,192 trainable parameters. The adapter was merged into the BF16 checkpoint. Validation probes covered model identity, arithmetic, coding, and factual recall.

Capabilities

• Code generation and debugging
• Instruction following and structured responses
• Reasoning-style responses
• XML-formatted tool calls through the included chat template
• English and Chinese text generation

Low-hardware deployment

The BF16 checkpoint requires roughly 2.1 GB for weights alone, plus runtime and KV-cache memory. The separate ONNX INT8 release reduces weight storage and CPU inference memory substantially. Limit context and generated-token counts on constrained devices.

Limitations

ShaziLLM-1B can hallucinate, produce incorrect code, and expose reasoning-like text. Do not treat its output as professional, security, legal, medical, or financial advice. Validate generated code before execution and isolate tool access behind deterministic authorization checks.
