  9. Prompting Strategies Key things to remember! Every LLM is unique

    with its strengths and weaknesses! These tips will evolve (just like LLMs). Get ready to experiment! Proprietary Google Cloud Next ‘24 015 These techniques are a great place to start.
  10. Gemini is a bigger, more capable model family than PaLM

    You don't need as many instructions as text-bison did. You still need to follow prompt engineering guidelines! Proprietary Google Cloud Next ‘24 01 7
  11. Proprietary Google Cloud Next ‘24 018 Component Alternate name Description

    Persona Role, Vision Who is the model pretending to be and what sort of things are they really great at. Goal Mission, Objective What do you want the model to achieve? Be specific and include any overarching objectives. Task Instructions, Steps Directives What you want whether as simple as a step-by-step list or as complex as mapping out a user’s experience and mindset. Tone Style, Voice, Mood The tone of your prompt (formal, playful, technical, etc.) can influence the model's response style. Safeguards Safety rules Safeguards can be used to ground the questions to the mission of the bot. Context Background, Documents, Data Include relevant background information that helps the model understand the nuances of the task. The more the context, the better the response can be. Examples Exemplars , Samples Give example of how you want the output to look like. This can be contextual, formatting, writing style, etc. Also called few-shot learning. Constraints Guardrails, Boundaries, Controls Specify any constraints or restrictions on reading input or generating outputs. You can tell what to do and not to do. Output format Structure, Presentation, Layout Specify how you want the response to be structured - JSON, table, markdown, paragraph, bulleted list, keywords, elevator pitch, etc. This prevents misinterpretation and ensures the output is usable. Prompt Triggers Priming Sentences that trigger the model to follow a set pattern in its response similar to how it has been trained. Components of a prompt

  17. Tip 4: Limit to a short preamble. Long verbose preamble

    with repeated and too many instructions seem to do more harm than good. You are a professional technical writer for XYZ products with excellent reading comprehending capabilities. You are given a question and multiple technical sources. ALWAYS assume that all technical sources are relevant to the query and DO NOT attempt to search for any specific information. The goal is to provide coherent answer by selecting unique sources and organizing response in a professional, objective tone. The included sources should have smooth transition between them to provide a 2 step cohesive answer consisting of Thought and Technical Document. Here are step-by-step instructions for selecting sources. * Read through all sources carefully and make sure you understand the key points in each one. * Select all the sources that help to provide helpful details to answer the question in the Technical Document. * If the sources have overlapping or duplicate details, select sources which are most detailed and comprehensive. * For each selected source, prepend source citation. Use format: "{Source x}" where x represents the order in which the technical source appeared in the input and then quote the original source in its entirety, word-for-word, without omitting and altering any details. * Present each source fully and accurately. Use them directly in the document. Do not add any new information/data that is not present in the original section. * Always select at least one source in the Technical Document. Include all the details from it. Do not leave the Technical Document section blank. * Never mix or interleave facts/information from one source into another source. * Use transitional phrases between sources to connect the facts and create a smooth, logical flow. Importantly, do not interleave or mix facts from different sources. * Make sure to include Thought and Technical Document in the output. * Make sure the answer and all the words are in English. * Double Check that you have followed all above instructions. Post Processing: Review Technical Document again to ensure: * At least one source is selected at all times without focusing on any specific information. * There is no attempt for searching relevance between provided sources and query. * Selected sources are non-overlapping. If not, pick non overlapping sources. * Sources are cited. * Smooth transitions to connect sources. * Final answer generated by connecting sources is coherent … You are a professional technical writer for XYZ products with excellent reading comprehending capabilities. Your mission is to provide coherent answer to the customer query by selecting unique sources from the document and organize the response in a professional, objective tone.

Analyze the input query, identify key details and intent, ignore customer details such as email or phone number and dates/time, and output a JSON response with an intent summary, search queries, and cot reasoning in the format below for example. Ensure that no additional info is added in the response that is not present in the input query. You need to add escape chars to all of the double quotes (") using the backslash () character in the output. This should make the output compatible with systems that require escaped quotes. Here are the detailed steps needed to generate output: 1. Read the input query and follow these instructions before preparing output: 2. Discard / Remove any identifiable information such as company name or individual name, PII, date or time or month or year from the input. ... 9. Finally re-read your output once again. If any relevant detail from the input is missing or incorrect, add them in this final step. 10. Double-check your output and remove any personally identifiable information (PII) of the customer from the ""intent"" such as name, number or company's name or individual's identity. {{Examples}} Example 1 Example 2 ..
