From ChatGPT: ATTENTION is Key to Good Prompts

Question for ChatGPT: How can I use knowledge of AI transformer attention to improve the effectiveness of my prompts for ChatGPT?

1.     Provide Sufficient Context: Transformer models use attention to weigh the importance of each word in the input when generating a response. (This is the purpose of role-playing.) Therefore, providing clear and sufficient context in your prompts will help the model generate more relevant and accurate responses. Keep in mind that if a conversation is very long, some of the older parts may be ignored due to the model's token limit (e.g., 2048 tokens for GPT-3), so the most relevant information should be closer to your current prompt.

2.     The Sequence of Information: Since attention mechanisms weigh all words in the input but give more importance to recent ones, the sequence in which you present information can impact the response. Important information is often better placed toward the end of your prompt.

3.     Avoid Ambiguity: Transformer models can struggle with ambiguous prompts because they cannot ask clarifying questions. They will make their best guess based on the attention scores, which may not align with what you intended. So, strive for clarity in your prompts.

4.     Use Instructive Prompts: Instructive prompts, where you tell the model what kind of answer you're looking for, can help get the desired output. For example, if you want a summarized answer, you can say, "In a short summary, explain...".

5.     Experiment with Different Prompts: Different prompt styles can lead to different responses because of how attention weights are assigned. If you're not getting the results you want, try rephrasing your prompt or presenting the information in a different order.

6.     Temperature & Max Tokens: You can adjust parameters like 'temperature' and 'max tokens’ to influence the response. Higher temperature values make the output more random, while lower values make it more deterministic.

7.     The 'max tokens' parameter limits the length of the response. Token Limitations: There is a maximum limit on the number of tokens the model can handle. For GPT-3, this is 2048 tokens, but it may vary for later versions. If a conversation exceeds this limit, you might need to truncate your text, this could cause the model to lose context.

8.     Incremental Queries: If your query is complex, you can break it down into multiple simpler queries. This can often result in better responses, as the model can handle each part separately.

9.     These suggestions are based on general principles and might need some experimentation & adjustments to get the best results for your specific case. The model doesn't genuinely understand the context or have real-world knowledge beyond its training data, manage your expectations.

The temperature parameter is used in the sampling process of a language model's output. It determines how focused or diverse the output will be. Here's how you adjust it: When you use an API like OpenAI's to interact with a model like GPT-4, you can specify the temperature as a parameter in your API call.

The temperature parameter controls the randomness of the model's responses:

  • High temperature values (close to 1.0) make the output more diverse and creative, but also more likely to be inconsistent or make errors.

  • Low temperature values (close to 0.0) make the output more focused and deterministic, often sticking closely to the style and content of the input. However, the responses can also be more repetitive and less creative.

You can adjust the temperature value according to the needs of your application. If you want more creativity and are okay with a bit of randomness, use a higher temperature. If you want more consistency and focus, use a lower temperature.

Remember, as of my knowledge cut-off in September 2021, the actual effect of the temperature parameter can depend on various factors, including the specific model version and the complexity of the input prompt.
