Step 4: Model Configuration and Hyperparameter Tuning

After data integration, fine-tuning your model's configuration is crucial:

• Base Model Selection: Choose from various GPT versions based on your specific needs (e.g., GPT-4 for complex tasks, GPT-3.5 for more general applications).

• Context Window: Determine the optimal amount of preceding text the model should consider:

  • Larger windows (8k-32k tokens) for tasks requiring extensive context
  • Smaller windows (1k-4k tokens) for more concise, focused responses

• Temperature Setting:

  • Low (0.1-0.5): For factual, consistent outputs
  • Medium (0.6-0.8): For a balance of creativity and accuracy
  • High (0.9-1.0): For more diverse, creative responses

• Top-p (nucleus sampling):

  • Lower values (0.1-0.5) for more focused, deterministic outputs
  • Higher values (0.6-0.9) for a broader range of possible responses

• Frequency and Presence Penalties: Adjust to control repetition and topic diversity in outputs

• Stop Sequences: Define custom stop tokens to control response length and structure

Prompt Engineer Perspective: Start with moderate settings (e.g., temperature 0.7, top-p 0.9) and systematically adjust based on output analysis. Document each configuration change and its impact on model performance.

Step 5: Training Process and Evaluation

With your data uploaded and settings configured, initiate the training process:
