## Introduction:
Recently, I explored the free course on ChatGPT prompt engineering for developers, led by the renowned Andrew Ng. I'm sharing the key insights I gained during this informative journey. We'll dive into the dos and don'ts of prompting, iterative prompt development, best practices, cases where it doesn't work, the remarkable capabilities, and much more.

## Do's of Prompting:

**Write Clear and Specific Instructions:**
- Precise prompts yield better results.
- Clearly communicate what you expect from the model.
- Use explicit language to frame your request.

**Iterative Prompt Development:**
- Crafting an effective prompt often requires refinement.
- Experiment with different prompt formulations.
- Refine your prompts based on model responses.

**Give the Model Time to Think:**
- Large language models may take a moment to generate responses.
- Use appropriate wait times before evaluating model outputs.
- Avoid rushing the model, especially for complex tasks.

## Don'ts of Prompting:

**Don't Assume Prior Knowledge:**
- Models don't possess real-time or specific domain knowledge.
- Avoid expecting the model to have access to current data.
- Provide context and information as needed.

**Don't Overload the Model:**
- Avoid overly long or complex prompts.
- Extremely verbose instructions may confuse the model.
- Keep prompts concise and to the point.

## Best Practices:

**Prompt Framing:**
- Use a system message to set the behavior and persona of the assistant.
- Whisper high-level instructions to guide the assistant's responses.
- Keep the user unaware of the system message.

**Context Management:**
- Provide all relevant messages in a conversation for context.
- Context is crucial for models to recall earlier interactions.
- Context ensures coherent and accurate responses.

**Temperature Control:**
- There is a parameter called "temperature", just like prompt.
- Adjust temperature to control response randomness.
- Lower values (e.g., 0.2) provide more deterministic responses.
- Higher values (e.g., 0.8) yield more varied and creative outputs.

## Cases Where It Doesn't Work:

**Lack of Specific Information:**
- Models lack real-time data and may provide outdated information.
- Avoid expecting precise details, especially in rapidly changing fields.

**Ethical Considerations:**
- Ensure applications built with large language models adhere to ethical guidelines.
- Avoid generating harmful, biased, or misleading content.

## Capabilities of Large Language Models:

**Summarization:**
- Models can summarize lengthy texts, making information more accessible.
- Useful for creating concise, informative content.

**Inference:**
- Models can provide answers, explanations, or predictions based on input data.
- Valuable for generating insights and responses.

**Transformation**:
- Models excel at converting text from one format or language to another.
- Simplifies tasks like translation, correction, and formatting.

**Expanding:**
- Generate longer text based on shorter prompts.
- Ideal for brainstorming, creative writing, and content generation.

**Building Chatbots:**
- Create custom chatbots for various applications.
- Automate tasks, provide customer service, or collect information interactively.

## Conclusion
Mastering the art of prompting large language models is a valuable skill for developers. Remember to iterate, experiment, and build with ethical considerations in mind. The possibilities are endless, and it's an exciting time to explore the potential of large language models.
