How AI Large Models are Revolutionizing Low-Code/No-Code Platforms​

Imagine a world where creating a powerful web application is as simple as describing what you want. No more endless lines of code, no more debugging nightmares, and certainly no more waiting for weeks or even months for a finished product. Welcome to the era of AI-enhanced Low-Code/No-Code platforms.

These platforms, combined with the might of AI large models, are not just a dream—they're the new reality. But how exactly does AI make this possible? Let’s embark on a journey to uncover this fascinating transformation.

The Magic of Low-Code/No-Code Platforms​

Before diving into the AI aspect, let's briefly touch on what low-code/no-code platforms are. These platforms are designed to simplify and accelerate the app development process:

  • Low-Code platforms offer a visual development environment where you can drag and drop components and write minimal code to customize your application. They strike a balance between simplicity and flexibility, allowing developers to build complex applications faster while still having the option to write custom code when needed.
  • No-Code platforms go a step further, allowing even those with no coding knowledge to build applications entirely through visual interfaces. They empower business analysts, project managers, and other non-technical users to create fully functional applications by configuring pre-built modules and defining workflows visually.

Now, let's see how AI is enhancing these platforms.

The AI Revolution: Making Development a Breeze​

1. Intelligent Code Generation​

Imagine telling your computer, "Create a login form with a username, password, and a submit button." Within seconds, AI generates the necessary HTML, CSS, and JavaScript. This isn’t science fiction; it’s happening right now. Platforms like OutSystems and AppGyver are integrating AI to offer such intelligent code generation.

For example, when using OutSystems, you might start by dragging a form component onto your canvas. Instead of manually adding fields and writing validation logic, you can describe your requirements in natural language, and the AI will generate the code for you. This feature not only saves time but also ensures that best practices and security standards are followed.

2. Automated Workflow Design​

Creating complex workflows can be daunting, especially for those unfamiliar with the intricacies of business logic. AI steps in to automate this process. By understanding your descriptions, it can set up everything from order processing in an e-commerce app to patient management in a healthcare system.

Take Microsoft Power Apps as an example. When you describe a business process, such as approving a vacation request, the AI can automatically generate the necessary workflows. It sets up the approval hierarchy, notification triggers, and data storage, allowing you to focus on refining the process rather than building it from scratch.

3. Natural Language Interfaces​

Have you ever wished you could just talk to your computer to build an app? AI makes this possible with natural language processing (NLP). Platforms like Bubble and AppSheet enable users to describe their needs in plain English, and the AI interprets these commands to build the corresponding features.

For instance, with Bubble, you can simply type "I need a user registration form with email and password fields," and the platform will create the form for you. This makes the development process more intuitive and accessible, especially for those who may not have a technical background.

4. Smart Recommendations​

As you build your app, AI can suggest components, templates, and best practices tailored to your needs. This is especially useful for newcomers who might not know the best way to proceed. Zoho Creator leverages AI to provide these smart recommendations, helping users create more efficient and effective applications.

Imagine you're building a CRM system. As you start adding components, Zoho Creator might suggest adding a lead scoring system based on your business model. These recommendations help ensure that you don't miss out on essential features and that your application adheres to industry standards.

5. Error Detection and Fixes​

No more hunting for bugs in your code! AI can automatically detect errors and suggest fixes, saving you hours of frustration. This feature is particularly powerful in platforms like OutSystems, which use AI to ensure your application is robust and error-free.

Consider a scenario where you're integrating a payment gateway. The AI can scan your code for common vulnerabilities and suggest improvements to enhance security. This proactive approach to error detection helps maintain the quality and reliability of your applications.

6. Automated Testing​

Testing is crucial but often tedious. AI can generate and execute tests automatically, ensuring your application works flawlessly. This not only speeds up the development process but also enhances the reliability of your application.

Platforms like AppSheet utilize AI to create test cases based on your application’s workflows and user interactions. By continuously testing and validating the application, AI helps catch issues early, reducing the risk of bugs in production.

7. User Behavior Analysis​

Understanding how users interact with your application can provide valuable insights. AI analyzes user behavior data to offer suggestions on improving user experience and application performance. This continuous feedback loop helps in creating applications that truly resonate with users.

For example, AI in AppGyver can analyze user navigation patterns and suggest layout changes to improve usability. By identifying bottlenecks and areas of friction, AI helps you optimize your application for a better user experience.

Welcome to an exciting journey where we combine the power of Svelte and Next.js to create a real-time code compilation and preview tool. Whether you're a seasoned developer or just getting started, this guide will help you build a dynamic application that brings your code to life instantly. We'll break down the process step-by-step and make it as enjoyable as possible. So, grab your favorite beverage, and let's dive in!

🚀 Setting the Stage: Project Setup​

First things first, let's set up our Next.js project. If you haven't already, create a new Next.js application with the following command:

npx create-next-app@latest svelte-repl
cd svelte-repl

Next, we need to install a few essential dependencies. These include Svelte for our compilation magic and Monaco Editor for a sleek code editing experience.

npm install monaco-editor @monaco-editor/react

🧙‍♂️ The Magic of Compilation: Web Worker​

To handle the heavy lifting of code compilation, we'll use a Web Worker. This keeps our main thread free and responsive. Create a file named compile.worker.js in the public directory with the following content:

self.onmessage = async (event) => {
  const svelteUrl = "https://unpkg.com/svelte";
  const version = "4.2.18";
  const compiler = await fetch(`${svelteUrl}/compiler.cjs`).then((r) =>
    r.text()
  );
  (0, eval)(compiler + "\n//# sourceURL=compiler.cjs@" + version);

  const { code } = event.data;
  try {
    const result = svelte.compile(code, { format: "esm" });
    self.postMessage({ result });
  } catch (error) {
    self.postMessage({ error: error.message });
  }
};

This worker listens for code updates, compiles the Svelte code, and sends the result back to the main thread. Think of it as a dedicated wizard, tirelessly transforming your code into magical outputs.

🖋️ Crafting the Code Editor​

Now, let's create a component for our code editor. This will be the playground where you write your Svelte code. Create a file named Editor.js in the components directory:

import React, { useRef, useEffect, useState } from "react";
import MonacoEditor from "@monaco-editor/react";

const Editor = ({ onChange }) => {
  const editorRef = useRef(null);
  const [code, setCode] = useState(
    `<script>
	let name = 'world';
</script>

<h1>Hello {name}!</h1>`
  );

  const handleEditorChange = (value) => {
    setCode(value);
    onChange(value);
  };

  return (
    <MonacoEditor
      height="350px"
      language="html"
      value={code}
      onChange={handleEditorChange}
      editorDidMount={(editor) => {
        editorRef.current = editor;
      }}
    />
  );
};

export default Editor;

This component leverages the Monaco Editor, providing a robust and user-friendly interface for writing Svelte code. As you type, it sends updates back to the main application.

🌟 The Preview Pane: Rendering the Output​

Next, we'll create a component to display the compiled Svelte code. This will be an iframe that dynamically updates with your latest code. Create a file named Preview.js in the components directory:

import React, { useRef, useEffect } from "react";

const Preview = ({ code }) => {
  const iframeRef = useRef(null);

  useEffect(() => {
    const iframe = iframeRef.current;
    const doc = iframe.contentDocument;
    doc.open();
    doc.write(`
            <style>${code.css ? code.css.code : ""}</style>
            <div id="app"></div>
            <script type="module">
                ${code.js ? getJsCode() : ""}
                try{
                  if (Component) {
                      new Component({ target: document.getElementById('app') });
                  }
                }catch(e){}
            </script>
        `);
    doc.close();
  }, [code]);

  function getJsCode() {
    return code.js.code
      .replace(
        "svelte/internal",
        "https://unpkg.com/svelte@4.2.18/src/runtime/internal/index.js"
      )
      .replace(
        "svelte/internal/disclose-version",
        "https://unpkg.com/svelte@4.2.18/src/runtime/internal/disclose-version/index.js"
      );
  }

  return (
    <>
      Preview
      <iframe
        ref={iframeRef}
        style={{
          width: "100%",
          height: "350px",
          border: "none",
          background: "#fff",
        }}
      />
    </>
  );
};

export default Preview;

This updated component not only injects the compiled code into an iframe but also includes a function getJsCode to replace module imports with URLs pointing to the Svelte runtime on a CDN. This ensures that your Svelte components run correctly within the iframe. The try...catch block around the component instantiation prevents runtime errors from breaking the entire preview.

🛠️ Bringing It All Together: The Main Page​

Now it's time to integrate our editor and preview components into the main page of our Next.js application.

"use client";
import React, { useState, useEffect } from "react";
import dynamic from "next/dynamic";

const Editor = dynamic(() => import("./components/Editor"), { ssr: false });
const Preview = dynamic(() => import("./components/Preview"), { ssr: false });

const Home = () => {
  const [code, setCode] = useState("");
  const [compiledCode, setCompiledCode] = useState({});

  useEffect(() => {
    const worker = new Worker("/compile.worker.js");
    worker.onmessage = (event) => {
      const { result, error } = event.data;
      if (error) {
        console.error(error);
      } else {
        setCompiledCode(result);
      }
    };

    if (code) {
      worker.postMessage({ code });
    }

    return () => {
      worker.terminate();
    };
  }, [code]);

  return (
    <div
      style={{
        display: "flex",
        flexDirection: "column",
        alignItems: "start",
        gap: "16px",
        padding: "2rem",
        fontWeight: "bold",
      }}
    >
      <h1>Svelte REPL with Next.js</h1>
      <Editor onChange={setCode} />
      <Preview code={compiledCode} />
    </div>
  );
};

export default Home;

In this setup, the Home component integrates our Editor and Preview components. It also sets up the Web Worker to compile the code whenever changes are made, seamlessly updating the preview.

🎉 Wrapping Up​

And there you have it! You've built a real-time Svelte compiler and preview tool using Next.js. This project is not just a great learning experience but also a powerful tool you can use and expand upon. Here's a quick recap of what we covered:

  • Setting up the Next.js project and installing dependencies.
  • Creating a Web Worker for Svelte code compilation.
  • Building a code editor using Monaco Editor.
  • Implementing a dynamic preview pane to display the compiled output.
  • Integrating everything into a cohesive and responsive application.

Feel free to customize and enhance this project further. Perhaps add syntax highlighting, error notifications, or additional features like saving and loading snippets. The possibilities are endless!

Writing prompts for large language models (LLMs) is an art and a science. Much like how a skilled artist uses brushes and colors to create a masterpiece, a proficient engineer uses words and context to craft prompts that yield optimal results. In this blog post, we’ll delve into the best practices for writing effective prompts, presented in a story-like fashion to keep things engaging and easy to understand.

What is a Prompt?​

Imagine you're a wizard, and the prompt is your spell. A well-crafted spell produces a powerful effect, while a poorly crafted one might not work as intended. Similarly, a well-written prompt can make the difference between receiving a precise, helpful response and getting an ambiguous or irrelevant one.

Prompts are the instructions given to LLMs, guiding them to generate the desired output. Think of them as the starting point of a conversation, setting the stage for the model to understand and respond appropriately.

Best Practices for Writing Prompts​

Best Practice 1: Quick Start with a Meta-Prompt​

To get started quickly, you can write a meta-prompt—a prompt that asks the model to help you write a prompt. This approach is akin to teaching a student how to frame questions to get the best answers from their teacher. This technique can save you time and provide a strong foundation for more specific prompts.

Meta-Prompt Example:

You are an expert in writing prompts for large language models. Explain how to write an effective prompt that achieves the desired result. Include examples and common pitfalls to avoid.

Using this meta-prompt, the LLM can provide a comprehensive guide on writing effective prompts, which you can then refine for your specific task.

Best Practice 2: Be Clear and Specific​

Clarity is king when it comes to prompts. The more specific and clear your instructions, the better the response. Ambiguity is the enemy; it can lead to vague or incorrect answers. This is similar to giving directions; the clearer you are, the more likely you’ll arrive at your desired destination.

Example of a Clear Prompt:

Write a short story about a young wizard who discovers their magical abilities in a small village.

Example of an Ambiguous Prompt:

Tell me a story.

Notice how the first prompt sets clear expectations about the story's content, while the second is too vague.

Best Practice 3: Provide Context​

Context is crucial. Imagine asking a friend to fetch something from a room without telling them what or where it is. Similarly, LLMs need context to generate relevant responses. Providing context helps the model understand the background and generate more accurate responses.

Example of Providing Context:

In the style of J.K. Rowling, write a short story about a young wizard who discovers their magical abilities in a small village.

By adding context about the style, you guide the model to produce a more tailored and coherent response.

Best Practice 4: Specify the Format​

If you need the output in a specific format, make it clear in your prompt. This ensures that the model understands your requirements and structures the response accordingly. This is particularly useful when you need structured data or a specific layout.

Example of Format Specification:

Create a bulleted list of the top five benefits of learning to code.

Expected Response:

- Enhances problem-solving skills
- Opens up job opportunities
- Encourages creativity
- Provides a high earning potential
- Facilitates continuous learning

Best Practice 5: Iterate and Refine​

Writing prompts is an iterative process. Start with a draft, test it, and refine based on the responses you receive. Even the best prompts can often be improved. Think of it like editing a piece of writing; the first draft is rarely perfect, and revisions help hone the final product.

Iteration Example:

First Draft:

Explain how a computer works.

Refined Draft:

Explain in simple terms how a computer processes data, including the roles of the CPU, memory, and storage.

Best Practice 6: Use Examples and Analogies​

Examples and analogies can help clarify complex instructions and make the prompt more relatable. They act as bridges between abstract concepts and the model's understanding, ensuring clearer communication.

Example with Analogy:

Explain how a neural network works, using the analogy of how the human brain learns from experience.

Best Practice 7: Anticipate Possible Misunderstandings​

Consider potential misunderstandings the model might have and address them in your prompt. By preempting these issues, you can craft a more precise prompt that avoids common pitfalls.

Example of Anticipating Misunderstandings:

Describe the steps to bake a cake, focusing on the sequence of mixing ingredients, baking time, and cooling period. Avoid discussing decoration techniques.

Best Practice 8: Include Instructions for Length​

If you need a response of a particular length, specify it in your prompt. This helps the model generate a response that meets your expectations in terms of detail and comprehensiveness.

Example of Length Specification:

Write a 200-word summary of the plot of 'The Great Gatsby.'

Best Practice 9: Test with Multiple Models​

Different models might interpret prompts slightly differently. Test your prompts with multiple models to ensure consistency and accuracy. This approach helps identify any variations in responses and refine prompts for broader applicability.

Best Practice 10: Seek Feedback​

Engage with a community or colleagues to get feedback on your prompts. Peer review can provide insights you might have missed and help improve the quality of your prompts.

Conclusion​

Writing effective prompts is like crafting a spell: it requires clarity, specificity, context, and refinement. By following these best practices, you can enhance the performance of LLMs and achieve more accurate and useful responses. Start with a meta-prompt, be clear and specific, provide context, specify the format, and always iterate and refine. Use examples and analogies, anticipate misunderstandings, include length instructions, test with multiple models, and seek feedback to continually improve your prompt-crafting skills.

Happy prompt crafting!

    value: i64,
}

enum Msg {
    AddOne,
}

impl Component for Model {
    type Message = Msg;
    type Properties = ();

    fn create(_: Self::Properties, link: ComponentLink<Self>) -> Self {
        Self { link, value: 0 }
    }

    fn update(&mut self, msg: Self::Message) -> ShouldRender {
        match msg {
            Msg::AddOne => self.value += 1,
        }
        true
    }

    fn view(&self) -> Html {
        html! {
            <div>
                <button onclick=self.link.callback(|_| Msg::AddOne)>{ "+1" }</button>
                <p>{ self.value }</p>
            </div>
        }
    }
}

Yew leverages Rust's powerful type system and concurrency model, making it a robust choice for building frontend applications that require high performance and reliability.

Seed​

Seed is another Rust framework for creating frontend web applications. It focuses on simplicity and developer productivity, providing an Elm-inspired architecture with Rust's safety and performance.

// Example of a simple Seed component

    Increment,
    Decrement,
}

fn update(msg: Msg, model: &mut Model, _: &mut impl Orders<Msg>) {
    match msg {
        Msg::Increment => model.counter += 1,
        Msg::Decrement => model.counter -= 1,
    }
}

fn view(model: &Model) -> Node<Msg> {
    div![
        button![ev(Ev::Click, |_| Msg::Increment), "+"],
        div![model.counter],
        button![ev(Ev::Click, |_| Msg::Decrement), "-"],
    ]
}

#[wasm_bindgen(start)]
pub fn start() {
    App::start("app", init, update, view);
}

fn init(_: Url, _: &mut impl Orders<Msg>) -> Model {
    Model { counter: 0 }
}

Seed's approach combines the best practices from functional programming with the performance benefits of Rust and WebAssembly, making it an excellent choice for building scalable and efficient web applications.

The integration of Rust into frontend development through WebAssembly and frameworks like Yew and Seed brings significant benefits in terms of performance, safety, and concurrency.

Introduction​

In the world of AI, particularly when working with large language models (LLMs) like GPT-4, the prompt you provide plays a crucial role in determining the quality and stability of the model's output. Writing effective prompts, especially longer ones, can be a bit of a challenge, but mastering this skill can significantly enhance the performance and reliability of your AI applications. This blog post will guide you through the best practices for crafting long, stable prompts, ensuring that your interactions with LLMs are as effective and consistent as possible.

What is Prompt​

A prompt is a piece of text or instruction provided to a language model to generate a desired response. It serves as the initial input that guides the model's output. The quality and clarity of the prompt significantly influence the relevance, accuracy, and coherence of the model's responses.

Prompts can vary in length and complexity, from simple questions or statements to detailed instructions. A well-crafted prompt provides sufficient context and specific guidance, reducing ambiguity and enhancing the model's ability to produce useful and relevant outputs. For instance, a simple prompt like "Explain the importance of water conservation" can yield general responses, while a more detailed prompt specifying the aspects to cover, such as environmental, economic, and social impacts, can lead to a more comprehensive and structured output.

Effective prompt design is crucial, especially when dealing with complex tasks. It involves clarity in language, providing necessary context, and being specific about the desired outcome. By mastering prompt engineering, users can leverage the full potential of large language models, ensuring that the responses generated are both insightful and reliable.

Understanding the Importance of Prompts​

Prompts are the initial input you provide to a language model to generate a desired output. They set the stage for the model's response and heavily influence the quality, relevance, and coherence of the output. A well-crafted prompt can lead to insightful, accurate, and useful responses, while a poorly designed one can result in vague, incorrect, or irrelevant answers.

Why Long Prompts?​

Longer prompts are often necessary when dealing with complex tasks that require detailed instructions or multiple pieces of information. They provide the model with sufficient context and guidance, reducing ambiguity and improving the relevance of the responses. However, writing long prompts requires careful consideration to maintain clarity and coherence.

Key Principles for Writing Effective Prompts​

Clarity​

Clarity is the cornerstone of an effective prompt. A clear prompt ensures that the model understands exactly what you are asking for.

  • Use Simple Language: Avoid jargon or overly complex sentences. The goal is to make your prompt easy to understand.
  • Be Direct: Clearly state your request or question. Avoid unnecessary information that could confuse the model.

Context​

Context provides the background information the model needs to generate a relevant response.

  • Background Information: Provide any necessary details that the model might need to understand the prompt fully.
  • Relevant Details: Include only the information that directly impacts the task at hand. Irrelevant details can distract the model and lead to less accurate responses.

Specificity​

Specificity ensures that the model knows exactly what you want.

  • Define the Scope: Clearly outline the scope of the task or question. Specify any constraints or requirements.
  • Ask Precise Questions: Instead of asking broad questions, break them down into more specific sub-questions.

Structuring Long Prompts​

When dealing with longer prompts, structuring your content becomes even more crucial. A well-structured prompt helps maintain clarity and coherence, making it easier for the model to understand and respond accurately.

Introduction​

Introduce the Task or Question

  • Set the Stage: Begin with a brief introduction that outlines the main task or question. This helps the model understand the overall objective.
  • Provide Necessary Background: Include any essential background information that is necessary for understanding the task.

Body​

Break Down the Task

  • Divide into Sections: For complex tasks, divide the prompt into clear sections or steps. This helps the model follow the logical flow of information.
  • Use Bullet Points or Lists: Organizing information in bullet points or lists can make it easier for the model to process and understand.

Conclusion​

Summarize and Reinforce

  • Summarize the Key Points: End with a brief summary that reinforces the main points of the prompt.
  • Reiterate the Objective: Clearly restate the desired outcome or the main question to keep the model focused.

Structured Template Example​

Below is a commonly used Markdown template for prompts, with various sections that can be expanded, contracted, or customized as needed.

# Role

Define the roles of a large model, such as specialists in specific areas.

# Background

Provide background information pertinent to the task.

# Requirements

Task requirements:

- Requirement 1;
- Requirement 2;
- Requirement 3;
  ...

# Work Steps

- Step 1;
- Step 2;
- Step 3;
  ...

Ensuring Stability in Model Outputs​

Stability in the outputs of a language model means that the responses are consistent and reliable over multiple interactions. Achieving this requires a combination of clear prompts, consistency in wording, and iterative testing.

Consistency​

Maintain Consistent Wording and Structure

  • Use Consistent Terminology: Ensure that you use the same terms and phrases throughout your prompt to avoid confusing the model.
  • Standardize Prompt Structure: Develop a standard structure for your prompts to make them more predictable for the model.

Reinforcement​

Reinforce Key Points

  • Repeat Important Information: Reiterate key details or instructions to reinforce their importance.
  • Bold font for key parts: When using Markdown syntax to format Prompts, use bold for the parts that require emphasis.
  • Capitalization of key parts: When writing Prompts in English, capitalization can be used to emphasize the parts that need to be emphasized, for example: "MUST..., DON NOT..."

Provide Examples​

Provide Positive Examples​

  • Provide positive examples to illustrate the desired response or format.

Provide Negative Examples​

  • Provide negative examples to illustrate the undesired response or format.

Testing and Iteration​

Iterative Testing for Improvement

  • Test Different Versions: Experiment with different versions of your prompt to see which one yields the best results.
  • Refine and Optimize: Based on the model's responses, refine and optimize your prompt to improve clarity and effectiveness.

Examples and Case Studies​

Example 1: Writing a Research Paper​

Initial Prompt:

确保模型输出的稳定性​

模型输出的稳定性意味着响应在多次交互中是一致且可靠的。实现这一目标需要结合清晰的 Prompt、一致的措辞以及迭代测试。

一致性​

保持一致的措辞和结构

  • 使用一致的术语：确保在 Prompt 中使用相同的术语和短语，以避免混淆模型。
  • 标准化 Prompt 结构：开发标准结构，使其对模型更具可预测性。

强化​

强化关键点

  • 重复重要信息：重申关键细节或指示，以强化其重要性。

  • 重点部分字体加粗：在使用 Markdown 语法格式组织 Prompt 时，对需要强调的部分可使用**加粗。例： **重点强调内容**。

  • 重点部分字体大写：对英文编写 Prompt 时，对需要强调的部分可使用大写以示强调。例： MUST..., DON NOT...。

提供示例​

提供正面示例​

  • 提供正面示例以说明期望的响应或格式。

提供反面示例​

  • 提供反面示例以说明不期望的响应或格式。

测试与迭代​

通过迭代测试进行改进

  • 测试不同版本：尝试不同版本的 Prompt，看看哪个能产生最佳结果。
  • 优化和改进：根据模型的响应，优化和改进您的 Prompt，以提高清晰度和有效性。
