To optimize hyperparameters for fine-tuning GPT-3/4 on specific tasks, common methods include grid search, random search, and advanced techniques like Bayesian Optimization or Hyperband. Here is the code snippet which you can refer to:

In the above code, we are using the following key steps:
- Define hyperparameter search space with trial.suggest_*.
- Train and evaluate the model using the suggested hyperparameters.
- Optimize to minimize loss or maximize accuracy.
Hence, this approach automates hyperparameter tuning for better fine-tuning performance.
