LangGPT

What is LangGPT

LangGPT is a new type of prompt design tool that proposes a structured and reusable prompt-writing methodology to help users write high-quality prompts. Inspired by programming languages, the tool designs a two-layer structured prompt design framework that is easy to learn and apply. Through built-in and extension modules, LangGPT supports flexible customization and adapts to different application scenarios. LangGPT has established an online community to promote the exchange and sharing of prompt design, improving the practicality and ease of use of the framework.

Main Features of LangGPT

• Systematic Templates: LangGPT provides a rich set of templates, and users can quickly write prompts based on the templates.
• Flexibility: By using variables, users can easily reference, set, and change the content in prompts.
• Interaction Friendliness: The workflow design of LangGPT makes user interaction simple and easy to guide users in using it.
• Modular Configuration: LangGPT fully utilizes the capabilities of large language models and responds to complex prompt requirements through modular configuration.
• Reminder Feature: Effectively alleviates the problem of long-term memory loss and maintains the coherence of conversations.

Technical Principles of LangGPT

• Two-Layer Prompt Design Framework：LangGPT adopts a two-layer structure, similar to the class and object structure in programming languages.
  • Built-in Modules: Defines a set of preset modules, such as Role, Goal, Constraint, etc. The modules contain the necessary internal elements of prompts.
  • Extension Modules: Supports users in adding new modules according to specific needs, improving the flexibility and extensibility of the framework.
• Modular Configuration：Prompts are decomposed into multiple modules, and each module represents a different aspect of interaction with large language models.Users can select and combine different modules as needed to build prompts suitable for specific tasks.
• Structured and Standardized：LangGPT emphasizes the structuring and standardization of prompts, making prompts clearer, easier to understand, and easier to reuse.It provides clear templates and formats, reducing the learning cost.
• Combination of Natural Language and Programming Language：The design inspiration comes from the structured characteristics of programming languages, while retaining the flexibility of natural language. Prompts are constructed by analogy with elements of programming languages, such as variables, functions, classes, etc.

How to Use LangGPT

Using LangGPT to write high-quality prompts (Prompt) can roughly be divided into the following steps:

• Understand the Core Concepts of LangGPT：
  • Templates: LangGPT provides a series of templates, such as the Role template, to guide users on how to construct prompts.
  • Variables: Use specific markers (such as "<VariableName>") to represent dynamic content in prompts.
  • Workflow: Define the steps and process for interacting with users.
• Choose an Appropriate Template: According to the role you want the large language model (LLM) to play or the task to complete, choose an appropriate template. For example, if you want the model to play the role of a poet, choose a template specifically designed for the poet role.
• Fill in the template content: According to the structure of the template, fill in the necessary information. This includes the role description, skills, rules, workflow, etc.
• Use variables: Use variables in the template to represent parts that can change, such as user input or specific attributes of the role.
• Define the workflow: Design the workflow for interaction between the role and the user, including how the role receives user input, how it responds, etc.
• Initialize the role: If needed, you can write initialization behavior for the role, which are steps executed before the role begins interacting with the user.
• Test and adjust: Input the written prompt into the large language model for testing. Based on the model's output, adjust and optimize the prompt.
• Use the LangGPT assistant: Use the LangGPT assistant to help design and optimize prompts. The assistant can generate corresponding prompt templates according to the user's needs.
