What is LangGPT?
LangGPT is a structured and reusable prompt-design framework for people who want a more systematic way to write and maintain prompts for large language models. Drawing on ideas from programming languages, it organizes a prompt into understandable parts such as a role, goals, rules, skills, and a workflow.
Users can start from a template, combine modules, and introduce variables or commands to represent changing parts of a prompt. They can then test the result with a language model and refine it, making the framework useful for individual prompt libraries as well as developers, content creators, and teams that need clearer, repeatable prompt-design practices.
Key features of LangGPT
Structured templates
Use layered templates to organize roles, goals, skills, rules, and workflows into a clearer prompt structure.
Prompt modularity
Break prompts into composable modules that can be selected, adjusted, and reused for different tasks.
Variables and commands
Represent changing content with variables and define commands as interaction entry points to reduce repeated prompt writing.
Workflow design
Define how a model receives input, identifies intent, applies skills, and delivers an outcome for more complex tasks.
Prompt iteration
Test a template with a large language model and refine its contents based on the output until it better matches the intended goal.
Community resources
Use examples, documentation, and community resources in the open-source project to learn structured prompt organization.
