+Aligning the model using Proximal Policy Optimization (PPO). The goal is to train the model to generate non-toxic reviews. The training process utilizes the `trl` library for reinforcement learning, the `transformers` library for model handling, and `datasets` for dataset management.
+Implementation code is available here: [GitHub](https://github.com/sathishkumar67/GPT-2-Non-Toxic-RLHF)
+```python
+# Load model and tokenizer directly
+from transformers import AutoTokenizer, AutoModelForCausalLM
+
+tokenizer = AutoTokenizer.from_pretrained("pt-sk/GPT2_NonToxic")
+model = AutoModelForCausalLM.from_pretrained("pt-sk/GPT2_NonToxic")
+
+# Example usage
+input_text = "The movie was fantastic"
+inputs = tokenizer(input_text, return_tensors='pt')
+outputs = model.generate(**inputs)
+
+print(tokenizer.decode(outputs[0], skip_special_tokens=True))
+```
