# 🦙 TinyLlama TRL Merged - Complete Fine-tuned Model
|
||||
|
||||
## 📋 Model Overview
|
||||
|
||||
This is a **fully merged and standalone model** of TinyLlama (1.1B parameters) fine-tuned using **TRL (Transformer Reinforcement Learning)** framework with LoRA adapters. The LoRA weights have been permanently merged into the base model, creating a single complete model that can be loaded without any adapter libraries.
|
||||
|
||||
### Key Features

|
||||
|---------|-------------|
|
||||
| **Standalone** | No PEFT library required — single model file |
|
||||
| **Fine-tuned** | Custom trained on educational Q&A dataset |
|
||||
| **Optimized** | FP16 precision for memory efficiency |
|
||||
| **Production Ready** | Single folder deployment |
|
||||
| **Chat Optimized** | Fine-tuned for conversational responses |
|
||||
|
||||

## 🚀 Usage Guide
|
||||
|
||||
### Installation
|
||||
```bash
|
||||
pip install transformers torch accelerate
|
||||
|
||||
Method 1: Direct Transformers Loading
|
||||
from transformers import AutoTokenizer, AutoModelForCausalLM
|
||||
import torch
|
||||
|
||||
# Load model and tokenizer
|
||||
model_id = "arif-butt/tinyllama-trl-merged"
|
||||
tokenizer = AutoTokenizer.from_pretrained(model_id)
|
||||
model = AutoModelForCausalLM.from_pretrained(
|
||||
model_id,
|
||||
torch_dtype=torch.float16,
|
||||
device_map="auto",
|
||||
trust_remote_code=True,
|
||||
)
|
||||
model.eval()
|
||||
|
||||
# Define prompt template
|
||||
prompt = "Q: What is machine learning?\nA:"
|
||||
|
||||
# Tokenize
|
||||
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
|
||||
|
||||
# Generate
|
||||
with torch.no_grad():
|
||||
outputs = model.generate(
|
||||
**inputs,
|
||||
max_new_tokens=150,
|
||||
temperature=0.7,
|
||||
top_p=0.95,
|
||||
do_sample=True,
|
||||
repetition_penalty=1.1,
|
||||
pad_token_id=tokenizer.eos_token_id,
|
||||
)
|
||||
|
||||
# Decode and print
|
||||
response = tokenizer.decode(outputs[0], skip_special_tokens=True)
|
||||
print(f"Prompt: {prompt}")
|
||||
print(f"Response: {response[len(prompt):].strip()}")
|
||||
|
||||
Method 2: Pipeline for Simple Inference
|
||||
from transformers import pipeline
|
||||
|
||||
pipe = pipeline(
|
||||
"text-generation",
|
||||
model="arif-butt/tinyllama-trl-merged",
|
||||
torch_dtype=torch.float16,
|
||||
device_map="auto",
|
||||
)
|
||||
|
||||
prompt = "Q: Explain neural networks in simple terms\nA:"
|
||||
result = pipe(prompt, max_new_tokens=150, temperature=0.7, do_sample=True)
|
||||
print(result[0]["generated_text"])
