Zyora-Byte-32B

An AI Teaching Assistant for Anna University Engineering Students, fine-tuned from Qwen2.5-Coder-32B-Instruct using QLoRA.

Model Details

Model Description

Zyora-Byte-32B (ByteBuddy) is a 32B parameter language model fine-tuned to help engineering students at Anna University with syllabus information, course details, problem-solving, and coding assistance. It understands both formal queries and casual student language.

• Developed by: Zyora Labs
• Model type: Causal Language Model (LoRA Adapter)
• Language(s): English
• License: Apache 2.0
• Finetuned from: Qwen/Qwen2.5-Coder-32B-Instruct

Model Sources

• Repository: zyoralabs/zyora-Byte-32B

Uses

Direct Use

• Answer syllabus questions for Anna University R2021 curriculum
• Provide course information (credits, semesters, prerequisites)
• Solve math problems (calculus, Laplace transforms, differential equations)
• Generate code with explanations (C, Python)
• Academic guidance for engineering students

Supported Branches

• Computer Science and Engineering (CSE)
• Electronics and Communication Engineering (ECE)
• Electrical and Electronics Engineering (EEE)
• Mechanical Engineering
• Civil Engineering
• Information Technology (IT)
• Computer Science - Data Science
• Computer Science - Cyber Security
• Computer Science - Business Systems (CSBS)

Out-of-Scope Use

• Non-Anna University curriculum queries
• Medical, legal, or financial advice
• Content generation for harmful purposes

Bias, Risks, and Limitations

• Focused specifically on Anna University R2021 curriculum
• Best performance for Semesters 1-4 (based on training data)
• May hallucinate for courses not in the training dataset
• Requires the base model (Qwen2.5-Coder-32B-Instruct) for inference

Recommendations

Users should verify critical academic information with official university sources. This model is meant to assist, not replace, official curriculum documents.

How to Get Started with the Model

from peft import PeftModel
import torch

# Load base model with 4-bit quantization
bnb_config = BitsAndBytesConfig(
    load_in_4bit=True,
    bnb_4bit_quant_type="nf4",
    bnb_4bit_compute_dtype=torch.bfloat16,
    bnb_4bit_use_double_quant=True,
)

base_model = AutoModelForCausalLM.from_pretrained(
    "Qwen/Qwen2.5-Coder-32B-Instruct",
    quantization_config=bnb_config,
    device_map="auto",
    trust_remote_code=True,
)

tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen2.5-Coder-32B-Instruct")

# Load LoRA adapters
model = PeftModel.from_pretrained(base_model, "zyoralabs/zyora-Byte-32B")

# Generate response
prompt = """<|im_start|>system
You are ByteBuddy, an AI teaching assistant helping engineering students understand their coursework.<|im_end|>
<|im_start|>user

"""

inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=512, temperature=0.7, top_p=0.9)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
